Description

Hypro centrifugal pumps are designed for agricultural and industrial spraying and transfer of a variety of fluids: water, insecticides, herbicides, wettable powders, emulsives, liquid fertilizers, etc. Polypropylene centrifugal pumps may also be used to pump acid fertilizer, calcium chloride and other highly corrosive liquids such as sulfuric and phosphoric acids.

Hypro Series 9300 hydraulic motor-driven centrifugal pumps provide smooth performance. They can be conveniently mounted on the tractor or sprayer, becoming part of the vehicle’s hydraulic system and freeing the PTO for other uses. The Hypro “close-coupled” design reduces the mounting space required, eliminating long shafts and couplers between the pump and motor.

General Information—Hydraulic Systems

Hydraulic Pumps

Hydraulic pumps come in two basic types:

Constant displacement - which will continue to put out its rated flow regardless of pressure, until the relief valve bypasses the flow.

Variable displacement - which will produce only the flow needed by the implement until the total pump output is reached. If less than the full pump output is required, an automatic stroke control mechanism decreases the pump output to maintain a constant pressure and flow. The output varies according to demand.

Spool Valves

There are two basic types of spool valves used in conjunction with these pumps — Open and Closed Center.

In the Open Center Valve (See Figure 1), the flow goes straight through the valve when in the neutral position. This type is used for constant displacement pumps where the flow should never be shut off.

Closed Center

Spool Valve

In Neutral

Position

Figure 2

The Closed Center Valve (See Figure 2) is used with variable displacement pumps. The flow is completely shut off in the neutral position, causing the pump stroke to adjust to zero flow. The flow stops, but the pump maintains a static pressure up to the valve.

Hydraulic Motors

Figure 3 shows an internal gear motor (Gerotor) where pressure causes the cavities between the gears to expand on one side, developing torque. The Gerotor type of hydraulic motor is used on Hypro pumps for its superior performance characteristics, including cooler running and higher rpm capabilities.

Three Systems

Fitting these components together and installing a motor, we have one of the three types of systems: Open Center,

Closed Center (pressure compensated) and Closed Center

Load Sensing (flow and pressure compensated).

Open Center Systems

In an Open Center System, the hydraulic pump puts out a constant flow. If the pump puts out more oil than the motor can use, a portion of the oil must be bypassed around the motor. When the oil is bypassed around a loop and does no work, the energy put into it by the pump turns into heat.

Therefore, the amount of oil bypassed should be kept to a minimum. Use the largest motor possible.

Closed Center (Pressure-Compensated) Systems

The Closed Center Pressure-Compensated system has a variable displacement pump which will deliver flow at the necessary rate to maintain a specified pressure. It is desirable to equip implements with a motor of a low flow range that will cause the pump to operate between 1800 and 2100 psi [124 and 145 BAR]. A motor that requires a large volume to obtain the correct implement speed usually causes the hydraulic pump in a closed center system to operate at a lower pressure than desirable. This low pressure results in unnecessary flow and the generation of heat that lowers the lubricating quality of the oil and may damage transmission parts. Use the smallest motor possible.

Closed Center Load Sensing Systems

(Flow and Pressure-Compensating)

The Closed Center Flow-Compensated System is a variation of the pressure-compensated system, designed primarily for more efficient operation and the generation of less heat. It works on the principle of maintaining a constant pressure drop from the pump to the work port of the selector valve. Any variation in demand at the motor will cause a change in flow. The system senses this change in flow due to the change in pressure drop across the valve and causes the pump to compensate by varying the pump flow. No restrictor is used in the pressure line and no oil is bypassed.

Installation Instructions

All Models — Open Center Systems

Models include Tank Port Adapter with built-in Check Valve

Assembly and Pressure Port Adapter.

HM2C and HM4C Models Only — Closed Center and

Small Open Center Systems.

Models include Tank Port Adapter with built-in Check Valve

Assembly and Pressure Port Adapter with three different size metering orifices for HM4C models. The orifices are not required for use with closed center systems with flow control, such as John Deere closed center systems. Also, do not use for small open center systems with a maximum flow of 8 gpm [30.28 lpm] for HM2C model; 10 gpm [37.85 lpm] for HM4C model. If necessary, the pressure port adapter may be used without a metering orifice installed in any closed center system, provided the pressure differential across the hydraulic motor does not exceed 2200 psi (15.2

Mpa).

NOTE: For applications over 2200 psi hyd: use HM1 or HM5.

Preliminary to Mounting

Consult the owners manual to determine the type and capacity of the hydraulic system. Make sure the hydraulic system is recommended to operate with a continuous load.

Refer to the Pump Selection Guide to confirm you have the proper pump for your hydraulic system.

Check to see that the pump impeller can be turned by hand.

(Turn the shaft clockwise using a deep socket wrench on the impeller nut.) If it cannot be turned, open the pump casing to look for obstructions. Clean out any corrosion build up where the casing fits over the eye of the impeller.

Pump Inlet Line

To achieve full capacity from the pump, the inlet line should be at least the same size as the inlet port on the pump. Reducing this line size will restrict the capabilities of the pump. The line must also be free of air leaks. Check all fittings and connections in the suction line for tightness.

The introduction of air may affect the priming and pumping capabilities of the pump. Use good quality suction hose that will not be collapsed by suction.

For non self-priming models, the centrifugal pump should be mounted below the liquid level and as near to the liquid source as possible to allow for the shortest suction line practical. To achieve optimal performance, the suction line should slope down into the pump. Avoid rises and humps that could trap air in the line to the pump. The suction line and pump should be filled with liquid prior to starting the pump, and all discharge lines should be open.

Pump Outlet Line

The recommended orientation for the outlet port is pointing straight up. This allows liquid to stay in the pump while it is priming. The outlet line should be the same size as the pressure port on the pump to give the optimal flow. The line should have as few restrictions and elbows as possible to optimize the pump performance and reduce pressure drop from the pump to the spray tips.

Priming the Pump

The Pump must not be run dry.

Before starting the pump, the inlet line and pump must be filled with liquid and all discharge lines must be open. On self-priming models, only the pump chamber needs to be filled with liquid. The pump must not be run unless it is completely filled with liquid because there is a danger of damaging the mechanical seal, which depends on the liquid for its lubrication.

Non-self-priming models should be mounted below the level of the liquid. The suction line should slope down to the pump and be free of dips and bends. If this cannot be done, a foot valve should be installed in the end of the inlet line so that the line can be completely filled with liquid before starting the pump.

For best priming results, the top vent plug should be removed from the pump casing, and a vent line (1/4" [ 6.35

mm] tubing is sufficient) should be installed running back to the top of the tank. This line prevents air lock and allows the pump to prime itself by bleeding off trapped air. The small stream of liquid that returns to the tank during operation is negligible. The discharge from this line should be positioned in the tank above the high liquid level. Self-priming models can be primed by removing the top vent plug and filling the priming chamber. The priming chamber will fill to the level of the inlet port. After use, the priming chamber should be flushed and drained to avoid chemical corrosion and damage from freezing. Drain by removing the lower drain plug.

Controlling the Pump Flow

The best way to control the flow is by incorporating two control valves in a pipe tee immediately after the strainer in the discharge line. This permits controlling agitation flow independently of nozzle flow.

In any centrifugal pump, it is the large volume of liquid which puts load on the drive. Use only the flow needed to develop the pressure required at the boom and to maintain adequate agitation. Hydraulic motor-driven centrifugal pumps are easily adjusted to the exact flow required, as explained in the Operating Instructions of this manual.

Centrifugal Pump Control

Hypro now offers many different components for spraying systems. The Hypro centrifugal pump control incorporates the electric flow control valve, a self-cleaning line strainer, a visual pressure gauge and a manual agitation control valve.

Flow Control Valve

A high-flow electric proportional valve allows for maximum flow control to the boom valves. It provides smooth, rapid control that can be controlled from either an electronic rate controller or switch box.

Strainers

The recommended placement of the strainer for a centrifugal pump is in the pump outlet line. This will eliminate any possible restriction that the strainer could create if it were installed in the inlet line. Ensure that the

-5-

proper strainer size and screen mesh are used to limit the pressure drop and achieve the best filtration. Line strainers can also be installed in the tank fill line to filter liquid as it is loaded into the tank as well as in the boom lines to further filter the solution prior to the spray tips. Tank baskets can also be used to filter material added through the tank lid.

Agitation

The centrifugal pump control contains a manual agitation control valve that can be adjusted to provide the right amount of flow to the jet agitators in the tank to ensure proper mixing within the tank.

Flowmeter

To eliminate the mechanical problems of a turbine flowmeter, we recommend that an electromagnetic flowmeter be used. These flowmeters have no moving parts to wear out and will provide a more consistent and accurate flow reading. They can be input into just about any electronic rate controller or switch box.

Boom Section Valves

For rapid response and reliability, we recommend electric plunger valves be used for boom control. The valves should be sized accordingly to minimize the pressure drop and maximize the flow rate. The boom tubing or hose should be sized accordingly to ensure that a pressure drop in the lines does not occur, causing inconsistent pressures at the nozzles.

Nozzle Bodies

Nozzle bodies with shut-off check valves are recommended to eliminate dripping from the spray tips when the boom valves are shut down.

Hooking Up the Hydraulic Motor to the

Tractor Hydraulic System

Hypro Series 9300HMC hydraulic motor-driven pumps can be mounted on either the tractor or sprayer. When hooking up, make sure that no dirt or liquid gets into the hydraulic motor. Keep all hydraulic connections clean. Be sure to connect the hydraulic motor into the system correctly by putting the pressure line to the Pressure Port Adapter and

Plumbing Installation

return line to the Tank Port Adapter. The port adapters on the hydraulic motor are sized to accommodate 1/2" NPT fittings. For maximum performance, the hydraulic lines should also be at least 1/2" [12.7 mm] in size. For lines longer than 8 feet [2.44 m] or for the HM3C models, hydraulic line size should be at least 3/4" [19.05 mm] in order to reduce heat generation.

The tank (OUT) port adapter with a built-in check valve assembly will guard against reverse operation — allowing you to reverse oil flow to operate other equipment. This

adapter must not be removed. On HM2C and HM4C model pumps, the pressure (IN) port adapter is a two-piece assembly consisting of an open (unrestricted) adapter with three orifices packed loose with the pump (See the

Operations Section).

When using the HM2C or HM4C unit on any flowcompensated (load sensing) closed center system, or any small open center system with a maximum flow of 8 gpm

[30.28 lpm] for HM2C or 10 gpm [37.85 lpm] for HM4C, the metering orifice should be removed from the pressure port adapter. When using these units on flow-compensated systems, connect to the motor priority circuit if your tractor has one.

Standard spool valves, which are found on all tractor hydraulic systems, may cause potentially damaging high peak pressures in the hydraulic system when closed because of abrupt shut-off of oil flow in both the supply and return lines. When shutting off the pump, move the selector to the FLOAT position to allow the centrifugal pump to come to a stop gradually.

For further information regarding Hypro products, contact your local dealer or

Hypro directly at www.hypropumps.com or by calling 1-800-424-9776.

Open Center Systems— All Models

Adjusting Centrifugal Pump Output

HM1C and HM3C motors have a bypass screw set 1-1/2 turns from fully closed at the factory. HM2C and HM4C have the bypass screw fully closed from the factory.

1. Open the bypass adjustment screw 2-1/2 turns from fully closed. Turn the bypass screw in to achieve the flow for the desired gpm and psi.

2. Start the tractor. Leave the directional valve in the neutral position and allow hydraulic oil to circulate for approximately 10 to 15 minutes or until adequately warmed.

Operation

3. Prime the centrifugal pump with all valves open (See the Installation Instructions and System Configuration

Diagram).

4. Close the agitation line valve and keep the control valve and the boom shut-off valve open. Note the spray pressure.

5. Open the agitation line valve until you have desired circulation in the tank. Recheck the spray pressure. If it is too low, close down the agitation line valve until the desired spray pressure is reached. If the spray pressure is too high, throttle the centrifugal pump by closing down the control valve.

-6-

Closed Center (Pressure-Compensated) —

HM2C and HM4C Models Only

On a pressure-compensated system, the amount of oil that is allowed to flow through the hydraulic motor is regulated by a metering orifice in the pressure port adapter. Three different sizes of orifices are supplied with the HM2C and

HM4C model pumps to allow flexibility in the flow required for individual sprayer needs.

The smaller the orifice, the less hydraulic oil goes through the motor, so the pump will run slower and the flow of liquid pumped and the spray pressure will also be less. As the hydraulic oil flow is increased (by installing a larger orifice), the amount of liquid being pumped and the spray pressure is also increased.

Installing and Removing Metering Orifice

1. Shut off the hydraulic system.

2. Disconnect the line to the pressure port of the hydraulic motor.

3. Remove the adapter from the motor using a 1-1/16'' wrench. Make sure the o-ring is on the metering orifice before installing into port adapter.

4. The orifice is removed or installed in the port adapter by tapping either in or out of the adapter.

A. To remove — tap the orifice out from the small end of the adapter.

B. To install — tap the orifice in from the large end of the adapter. The orifice is seated when a snap sound is heard.

Adjusting Centrifugal Pump Output

1. Open the bypass adjusting screw in the hydraulic motor three (3) turns.

2. Start the tractor and allow the hydraulic oil to circulate for approximately 10 to 15 minutes or until adequately warmed.

3. Close and lock down the bypass adjusting screw in the hydraulic motor.

4. Prime the centrifugal pump with all valves open (See

Installation Instructions and System Configuration

Diagram).

5. Close the agitation line valve and the control valve; open the boom shut-off valve.

6. With the pump running, open the control valve until the pressure gauge indicates the desired spraying pressure.

7. Open the agitation line valve until sufficient agitation is observed. Then, if spray pressure drops, readjust the control valve to restore to the desired pressure.

8. If a sufficient boom pressure cannot be attained, install the #2 size orifice and repeat Steps 5 through 7.

9. If a sufficient boom pressure still cannot be attained with the #2 size orifice, install the #3 size orifice and repeat

Steps 5 through 7.

10. If a sufficient boom pressure still cannot be attained with the #3 size orifice, remove the orifice and repeat

Steps 5 through 7.

Closed Center (Load Sensing) — All Models

Many tractors are being introduced with load sensing systems (also referred to as flow and pressure-

-7-

compensated systems) which simplify system setup and eliminate many of the problems associated with using the wrong size pump motors on a given hydraulic system.

Usually, any of Hypro’s 9300HMC models may be used on this type of system, provided the hydraulic system produces sufficient oil flow for the hydraulic motor being used (Refer to the Pump Selection Guide).

This system maintains a constant flow of hydraulic oil for a given pressure drop. The flow is adjustable with a flow control valve installed in the hydraulic system (such as the

Tortoise/Hare control on John Deere tractors). Because this system has adjustable flow, there is no need to bypass hydraulic oil as in an open center system, or to restrict the flow with orifices as in a closed center pressurecompensated system.

Adjusting Centrifugal Pump Output

1. Make sure the orifice from the pressure port adapter of the hydraulic motor has been removed (HM2C and

HM4C models only).

2. Close and lock down the bypass adjusting screw in the hydraulic motor.

3. Set the tractor hydraulic flow control valve for minimum hydraulic oil flow to the remote outlet (Tortoise position).

4. Start the tractor and allow the hydraulic oil to circulate for approximately 10 to 15 minutes or until adequately warmed.

5. Prime the centrifugal pump with all valves open (See the Installation Instructions and System Configuration

Diagram).

6. Close the agitation line valve and open the control valve and the boom shut-off valve.

7. Slowly adjust the tractor hydraulic flow control valve until the desired boom pressure is attained.

8. Open the agitation line valve until sufficient agitation is observed. If spray pressure drops, readjust the tractor hydraulic flow control valve to restore it to the desired pressure.

Flush Pump After Use

One of the most common causes for faulty pump performance is gumming or corrosion inside the pump.

Flush the pump and entire system with a solution that will chemically neutralize the liquid pumped. Mix this solution according to the manufacturer’s directions. This will dissolve most residue remaining in the pump, leaving the inside of the pump clean for the next use.

To Prevent Corrosion

After cleaning the pump as directed above, flush it with a permanent-type automobile antifreeze (Prestone®, Zerex®, etc.) containing a rust inhibitor. Use a 50% solution, half antifreeze and half water, or fill the pump with FLUID FILM® and then drain it. A protective coating of FLUID FILM® will remain on the inner pump surfaces. Save the excess FLUID

FILM® for the next application. Plug the ports to keep out air during storage. For short periods of idleness, noncorrosive liquids may be left in the pump, but air must be kept out.

Plug the ports or the seal port connections.

Instructions in italics describe procedures for the

Series 9300P Polypropylene Centrifugal Pumps, when different than the cast iron pumps.

1. Using a 9/16" box end wrench, remove the four Hex

Head Bolts holding the Pump Casing to the Mounting

Flange. (If necessary, tap Pump Casing Outlet Port with rubber mallet or hammer to separate.) [Using a 1/2"

wrench, remove the six bolts from the front. For the two bottom bolts securing the base, you will need to hold the two nuts with another 1/2" wrench. Also remove the

5/16" screw from the rear near the outlet port.]

2. To remove the Impeller Nut, insert a large screwdriver or file (at least 10" [254 mm] long) into Impeller Vanes to prevent Impeller from turning when loosening nut. Use a

5/8" socket wrench to remove the Impeller Nut by turning it counterclockwise (See Figure 6). [Use 7/8"

deep socket wrench to remove Plastic Seal Nut, then

9/16" deep socket to remove Metal Jam Nut and

Washer.]

3. Once nut [and washer] is removed, place a screwdriver on each side behind the Impeller and pry away from the

Mounting Flange (See Figure 7). Remove Woodruff Key from the Shaft. Remove O-ring from the Mounting

Flange.

Pump Seal Removal

1. Lightly lubricate the Shaft for easier removal of the Seal.

Using two screwdrivers positioned opposite each other, pry the rotary portion of the Seal from the Shaft (See

Figure 8).

Figure 8

In the case of a severe Pump Seal leak, inspect the

Shaft/Bearing Assembly in the Hydraulic Motor for possible contamination.

2. Using a 1/2'' box end wrench, remove the four bolts holding the Motor to the Mounting Flange. Remove

Motor. [Remove the Plastic Back Cover flange. Knock

the Seal out from back with a hammer and screwdriver.

Use a 1/2'' socket wrench and 1/2'' box end wrench to

remove the Mounting Flange from the Hydraulic Motor.]

Figure 6

Figure 7

-8-

3. Using a screwdriver and hammer, tap out the stationary portion of the Mechanical Seal from the Motor side of the Mounting Flange. (If the Motor is not removed, the

Seal can be pried out with a small screwdriver.)

The seal will be damaged by removal in this manner. A new seal must be used when pump is reassembled.

Clean-Up Of Pump Housing

1. Using a circular bottle-type wire brush with air or hand drill, clean the Outlet Port, Inlet Port and the sealing areas of the O-ring on the Pump Casing and Mounting

Flange. Using the port brush, clean the seal cavity in the

Mounting Flange. [The last step should not be

performed on the 9300P.]

2. After wire brush cleaning, it is recommended that the

Pump Casing and Mounting Flange be further cleaned in a solvent tank to remove rust and corrosion particles.

Seal Replacement/Pump Housing Reassembly

The threads of the Plastic Seal Nut are fine and can be easily cross threaded. To prevent cross threading, turn the Plastic Seal Nut counterclockwise until area of thread engagement is detected; then turn the Plastic

Seal Nut clockwise until it is secure. Do not over tighten the Plastic Seal Nut.

6. Insert a Woodruff Key into the Shaft key slot; then place the Impeller on the Shaft and align it with the Key and press against the Mechanical Seal Assembly. Apply a blue thread locking compound to the Impeller Nut, and using a 5/8'' socket wrench and using a screwdriver to hold the Impeller, install the Impeller Nut. [On

polypropylene models, insert the Woodruff Key into the

Shaft key slot. Place the Impeller on the Shaft and align it with the Key; then press against the Mechanical Seal

Assembly. Place the Metal Seal Washer on the Shaft.

Apply a drop of blue thread locking compound on the

Impeller Nut and secure the Impeller to the Shaft as

described previously.]

7. Install the O-ring on the Mounting Flange. Replace the

O-ring if worn or damaged.

8. Place the pump casing on the mounting flange, insert and tighten the bolts.

Disassembly and Repair of the Hydraulic Motor

If the Hydraulic Motor requires repair, proceed to

Disassembly and Repair of the Hydraulic Motor.

1. Lubricate the seal cavity in the Mounting Flange with

WD-40

®

, LPS or equivalent. Do not lubricate the shaft.

2. Install the stationary portion of the Mechanical Seal by sliding over the Shaft with the ceramic side out.

The work area and motor should be as clean as possible to prevent contamination of parts.

Make sure both the seal cavity and seal are clean and lubricated.

3. To seat the Seal in the seal cavity, use a piece of 3/4"

PVC pipe 4" to 6" [101.6 to 152.4 mm] in length.

Lubricate sealing surface on seal after it is seated. Do not lubricate the shaft.

4. To install the rotary portion of the mechanical seal, place it over the shaft with the carbon side facing in, and press against the stationary portion (See Figure 9).

Figure 9

5. Install rubber gasket 1700-0100 over shaft against rotary portion of seal.

On Models 9305C-HM3C-SP, 9505C-HM3C-BSP, and

9305C-HM3C, install the Washer on the Shaft prior to installing the Impeller Nut.

Figure 10

1. Remove the Mounting Flange from the Motor body and place Hydraulic Motor in vise (Figure 10).

2. Remove Tank Port Adapter and Pressure Port Adapter with large crescent wrench or 1-1/16" box end wrench

(See Figure 10).

3. Using a 9/16" box end wrench, loosen the Nut on the

Bypass Adjusting Screw (See Figure 10).

4. Using a small screwdriver, remove the Bypass Adjusting

Screw from the Motor. (This will remove the Screw, Nut,

Washer and Thread-Seal Gasket.)

5. Using a 1/4" Allen wrench, remove the Socket Head

Cap Screws from the Motor End Plate (See Figure 10).

6. If Motor End Plate will not lift off easily, use a small screwdriver to carefully pry apart the boss portion of the

End Plate and Gerotor Housing until free (See Figure

11). If Gerotor Housing will not lift off easily, carefully pry

apart the boss area between the Gerotor Housing and the Motor Body. (It may be necessary to alternate sides when prying apart Motor sections.)

Figure 11

7. Remove both parts of the Gerotor.

8. On HM3C models, remove the Woodruff Key from the

Shaft. On HM1C, HM2C and HM4C models, remove the Roll Pin from the Shaft.

9. Remove the O-ring from the Motor End Plate and Body with a flat instrument such as a knife blade.

10. Inspect Motor End Plate, Body and Gerotor Housing for wear and/or gouging. If gouging has occurred in both the Motor End Plate and Body, the Motor is not repairable. If gouging has occurred in the Motor End

Plate, Body or Gerotor Housing, the part that is worn must be replaced. If Gerotor Housing is damaged,

Gerotor parts must also be replaced.

Hydraulic Motor Shaft Disassembly and Repair

1. Remove Large Retaining Ring from Shaft with a screwdriver. Remove Thrust Bearing Assembly from

Shaft (includes the Thrust Bearing and two Thrust

Bearing Races) and the Seal Spacer.

2. Remove the Small Retaining Ring next to the Shaft Ball

Bearing.

3. To remove the Bearing from the Shaft, place the Shaft

(threaded end up) in the arbor press fixture. Place the two support bars provided in the repair kit opposite each other and between the Seal on the Shaft and the arbor press fixture. Using an arbor press, press the Shaft through the

Bearing, Seal Spacer and Seal (See Figure 13).

To Remove the Shaft Assembly from the Motor Body

1. Remove the Slinger Ring from the Motor Shaft.

Special attention should be exercised when working with retaining rings. Always wear safety goggles when working with spring or tension loaded fasteners or devices.

2. Using the large retaining ring pliers, remove the Retaining

Ring next to the Ball Bearing in the Motor Body.

If Bearing is binding against the Retaining Ring so that it cannot easily be removed, place the Motor Body

(threaded portion of the shaft up) on arbor press. Using a piece of un-threaded metal pipe (1" dia. x 4" high [254.

mm x 101.6 mm high]), slide over the Shaft and gently press down with the arbor press just enough to relieve the pressure on the Retaining Ring.

Figure 12

3. Place Body in position on arbor press. Threaded portion of the Shaft should be inside the fixture. Press out Shaft assembly with arbor press (See Figure 12).

Figure 13

4. Inspect the sealing area of the Shaft for wear. Inspect other Shaft Assembly Components for wear and replace if necessary.

5. While Motor is completely disassembled, clean all parts in a solvent bath.

To Install New Shaft Seal

1. The sealing lips on a new Seal must be expanded to fit on the Shaft. Press seal onto large end of Shaft with seal lip facing out. Do not push Seal past keyway on

Shaft.

2. Once seal lip has been expanded, remove the Seal from the Shaft.

3. With the seal lip facing the large end of the Shaft, slide the Seal over the threaded end of Shaft and gently push onto the raised area of the Shaft, stopping approximately 1/4" [6.35 mm] from the Large Retaining

Ring groove.

4. Over the large end of the Shaft, install the Seal Spacer,

Thrust Bearing Race, Thrust Bearing, second Thrust

Bearing Race and the Large Retaining Ring.

To Install Shaft Bearing

1. Over the threaded end of the Shaft, install the Spacer

Ring and the Ball Bearing.

2. Insert the Shaft (threaded end down) into the arbor press fixture. Place the two support bars opposite each other and between the Bearing and the fixture. Place on an arbor press and carefully press the Shaft down, allowing just enough room for the Retaining Ring next to the Bearing to be installed.

-10-

Make sure the Spacer ring between the seal and

Bearing is free floating (not binding).

Should the Main Needle Bearings in the Hydraulic Motor need replacement, a new Body and/or End Plate with the Main Bearing already installed, must be used. If this occurs, check other internal parts of the Motor for damage and wear.

To Install the Shaft Assembly in the Motor Body

1. Place the Shaft Assembly into the Motor Body bearing bore with threaded end up (See Figure 14).

Figure 14

2. On arbor press, place Body on arbor press fixture.

Make sure the surface edge of the fixture is smooth and clean.

An un-threaded piece of pipe (1" dia. x 4" [25.4 mm x

101.6 mm] high) is needed to support the outer bearing race on the shaft ball bearing. Place this pipe over the shaft and press shaft assembly down until retaining ring can be installed in its groove in the bearing core of the motor body (Figure 15).

Figure 15

Reassembly of Remaining Hydraulic Motor Parts

1. Place Motor Body in a vise with large end of Shaft facing up.

2. Install the O-ring in the Body.

3. Install the Woodruff Key or Roll Pin on the Shaft. Place the Inner Gear of the Gerotor onto the Shaft making sure Gerotor slot lines up with the key in the shaft.

The Woodruff Key can slide up behind the inner gear of the gerotor when the gear is installed. Make sure the key is visible in the slot after the gear is in place.

4. Install the outer portion of the Gerotor, making sure the

Gerotor is centered within the O-ring groove on the

Body.

5. Install the Gerotor Housing, making sure the pins in the

Gerotor Housing line up with their respective holes in the Body.

6. Lightly lubricate the area between the Inner and Outer

Gerotor and the Outer Gerotor and Gerotor Housing with hydraulic oil or mineral oil.

Special attention should be exercised when working with retaining rings. Always wear safety goggles when working with spring or tension-loaded fasteners or devices.

7. Install O-ring on the motor end plate.

8. Place end plate on gerotor housing, making sure holes in end plate line up with pins in the gerotor housing.

9. Install four Socket Head Cap Screws in Motor End

Plate, and using a 1/4" Allen wrench, tighten Cap

Screws alternately and evenly in a crisscross pattern to approximately 15 foot pounds [ 20 Nm] of torque.

10. Install the Thread Seal Gasket on the Bypass Adjusting

Screw. Put the Gasket on from the slotted end and turn until four threads on the Screw are showing. Install the

Washer and the Nut. Install Bypass Adjusting Screw in the Motor end plate.

A. For closed center hydraulic systems, turn the

Bypass Adjusting Screw in until it bottoms out in the

End Plate. Tighten nut down with 9/16" box end wrench.

B. For open center hydraulic systems, turn the Bypass

Adjusting Screw in until it bottoms out in the End

Plate; then turn back out 1

1

2 full turns. Holding the

Bypass Adjusting Screw with a screwdriver, tighten

Nut. (Motor will then have to be readjusted to tractor system.)

11. Replace O-ring on both port adapters.

12. Install Pressure Port Adapter and Tank Port Adapter back onto the Motor. (For ease of installation, tighten the Pressure Port Adapter first, then the Tank Port

Adapter.)

13. Remove Hydraulic Motor from the vise. Turn Shaft by hand to check for binding.

14. Install Slinger Ring over Motor Shaft.

15. Install Motor into Pump Mounting Flange. Insert four

Hex Head Bolts; then alternately and evenly tighten them. [For polypropylene models, secure the Hydraulic

Motor to the Mounting Flange with four Hex Head Cap

Screws and Nuts. The Nuts should be visible when the

assembly is complete.]

If the proper Hydraulic Pump Unit has been selected according to Hypro recommendations, and the unit has been correctly plumbed into the hydraulic system, operation should be quite satisfactory. If spraying performance is unsatisfactory or hydraulic system heat is excessive etc., check the following troubleshooting guide for possible problems and solutions.

Symptom

Low Discharge

Probable Cause(s)

Pump not primed.

Air leaks in inlet line.

Blocked or clogged line strainer.

Impeller plugged.

Undersize inlet line or collapsed hose.

Improperly sized hydraulic motor.

Bypass Adjustment Screw not set properly.

Eye of impeller rubbing on volute.

Hydraulic system Improper hydraulic motor size.

overheating

Improper metering orifice installed in pressure port.

Insufficient hydraulic hose size.

Troubleshooting Guide

Corrective Action(s)

— Remove topmost vent plug from face of pump and run pump to expel trapped air (See Installation Instructions).

— Check and reseal inlet fittings.

— Inspect strainer and clear any debris from screen.

— Inspect and clear obstruction.

— Suction line should be the same diameter as inlet port of pump or larger.

— Refer to Pump Selection Guide to determine proper size hydraulic motor for your hydraulic system.

— Adjust bypass screw on side of hydraulic motor in until the desired output is attained.

— Remove volute (front cover) and inspect the impeller.

If wear detected, sand the impeller eye O.D. with emery cloth.

— Refer to Pump Selection Guide to determine proper size for your hydraulic system.

— Close adjustment screw on side of hydraulic motor to lessen the amount of oil being bypassed.

— Install proper size orifice. Refer to Installation section for proper sizing.

Limited Warranty on Hypro Pumps and Other Hypro Products

Hypro warrants to the original purchaser of its products (the “Purchaser”) that such products will be free from defects in material and workmanship under normal use for the period of one (1) year for all products except: oil crankcase plunger pumps will be free from defects in material and workmanship under normal use for the period of five (5) years, and accessories will be free from defects in material and workmanship under normal use for the period of ninety (90) days. In addition, Hypro warrants to the purchaser all forged brass pump manifolds will be free from defects in material and workmanship under normal use and from damage resulting from environmental conditions for the life of the pump.

“Normal use” does not include use in excess of recommended maximum speeds, pressures, vacuums and temperatures, or use requiring handling of fluids not compatible with component materials, as noted in Hypro product catalogs, technical literature, and instructions. This warranty does not cover freight damage, freezing damage, normal wear and tear, or damage caused by misapplication, fault, negligence, alterations, or repair that affects the performance or reliability of the product.

THIS WARRANTY IS EXCLUSIVE. HYPRO MAKES NO OTHER WARRANTY, EXPRESS OR IMPLIED, INCLUDING BUT NOT

LIMITED TO ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

Hypro’s obligation under this warranty is, at Hypro’s option, to either repair or replace the product upon return of the entire product to the Hypro factory in accordance with the return procedures set forth below. THIS IS THE EXCLUSIVE REMEDY FOR ANY BREACH

OF WARRANTY.

IN NO EVENT SHALL HYPRO BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND, WHETHER

FOR BREACH OF ANY WARRANTY, FOR NEGLIGENCE, ON THE BASIS OF STRICT LIABILITY, OR OTHERWISE.

Return Procedures

All pumps or products must be flushed of any chemical (ref. OSHA Section 0910.1200 (d)(e)(f)(g)(h)) and hazardous chemicals

must be labeled before being shipped* to Hypro for service or warranty consideration. Hypro reserves the right to request a

Material Safety Data sheet from the Purchaser for any pump or product Hypro deems necessary. Hypro reserves the right to

“disposition as scrap” pumps or products returned which contain unknown substances, or to charge for any and all costs incurred for chemical testing and proper disposal of components containing unknown substances. Hypro requests this in order to protect the environment and personnel from the hazards of handling unknown substances.

For technical or application assistance, call the Hypro Technical/Application number: 1-800-445-8360.

To obtain service or warranty assistance, call the Hypro Service and Warranty number: 1-800-468-3428; or call the Hypro Service and Warranty FAX: (651) 766-6618.

Be prepared to give Hypro full details of the problem, including the following information:

1. Model number and the date and from whom you purchased your pump.

2. A brief description of the pump problem, including the following:

• Liquid pumped. State the pH and any non-soluble materials, and give the generic or trade name.

• Temperature of the liquid and ambient environment.

• Suction lift or vacuum (measured at the pump).

• Discharge pressure.

• Size, type, and mesh of the suction strainer.

• Drive type (gas engine/electric motor; direct/belt drive; tractor PTO) and rpm of pump.

• Viscosity (of oil, or other than water weight liquid).

• Elevation from the pump to the discharge point.

• Size and material of suction and discharge line.

• Type of spray gun, orifice size, unloader/relief valve.

Hypro may request additional information, and may require a sketch to illustrate the problem. Contact the factory to receive a return material authorization before sending the product. All pumps returned for warranty work should be sent shipping charges prepaid to:

* Carriers, including U.S.P.S., airlines, UPS, ground freight, etc., require specific identification of any hazardous materials being shipped.

Failure to do so may result in a substantial fine and/or prison term. Check with your shipping company for specific instructions.

Note: This warranty does not apply to Hypro Pump Kit Model 1538,

1551, 1538-SP and 1551-SP. This is because the user could incorrectly assemble the parts and cause the pump to work improperly.
