WARNING

FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.

Read and understand all instruction manuals before operating equipment.

EQUIPMENT MISUSE HAZARD

General Safety

Any misuse of the spray equipment or accessories, such as overpressurizing, modifying parts, using incompatible chemicals and fluids, or using worn or damaged parts, can cause them to rupture and result in fluid injection or other serious bodily injury, fire, explosion or property damage.

NEVER alter or modify any part of this equipment; doing so could cause it to malfunction.

CHECK all spray equipment regularly and repair or replace worn or damaged parts immediately. the back cover. Always read the fluid and solvent manufac­ turer's literature before using them in this pump.

Pressure Relief Procedure

To reduce the risk of serious bodily injury, including splashing in the eyes or on the skin or injury from moving parts, always follow this procedure whenever you shut off the pump, when checking or servicing any part of the spray system, when in­ stalling, cleaning or changing fluid tips, and whenever you stop spraying.

Read and follow the fluid and solvent manufacturer's literature regarding the use of protective clothing and equipment.

System Pressure

This pump can develop 900 psi (62 bar) MAXIMUM WORK­

ING PRESSURE, at 180 psi (12 bar) MAXIMUM INCOMING

AIR PRESSURE. Be sure that all spray equipment and ac­ cessories are rated to withstand the maximum working pressure of this pump. DO NOT exceed the maximum working pressure of any component or accessory used in the system.

1. Shut off the air to the pump.

2. Close the bleed-type master air valve (required in your system).

3. Hold a metal part of the gun firmly to the side of a ground­ ed metal pail, and trigger the gun to relieve pressure.

4. Open the drain valve (required in your system), having a container ready to catch the drainage.

5. Leave the drain valve open until you are ready to spray again.

Fluid Compatibility

BE SURE that all fluids and solvents used are chemically com­ patible with the wetted parts shown in the Technical Data on

If you suspect that the fluid tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the hose end coupling and relieve pressure gradually, then loosen completely. Now clear the fluid tip or hose.

FIRE OR EXPLOSION HAZARD

Static electricity is created by the flow of fluid through the pump and hose. If every part of the spray equipment is not properly grounded, sparking may occur, and the system may become hazardous. Sparking may also occur when plugging in or unplugging a power supply cord. Sparks can ignite fumes from solvents and the fluid being sprayed, dust particles and other flammable substances, whether you are spraying in­ doors or outdoors, and can cause a fire or explosion and serious bodily injury and property damage.

If you experience any static sparking or even a slight shock while using this equipment, STOP SPRAYING IMMEDI­

ATELY. Check the entire system for positive grounding. Do not use the system again until the problem has been identified and corrected.

Grounding

To reduce tne risk of static sparking, ground the pump and all other spray equipment used or located in the spray area.

CHECK your local electrical code for detailed grounding in­ structions for your area and type of equipment. BE SURE to ground all of this spray equipment:

1. Pump: use ground wire and clamp as shown in Fig 1.

2.

Air and fluid hoses: use only grounded hoses with a max­ imum of 500 feet (150 m) combined hose length to en­ sure grounding continuity.

3.

Air compressor: according to manufacturer's recommen­ dations.

MOVING PARTS HAZARD

The piston in the air motor, located behind the air motor plates moves when air is supplied to the motor. Moving parts can pinch or amputate your fingers or other body parts. Therefore,

NEVER operate the pump with the air motor plates removed.

KEEP CLEAR of moving parts when starting or operating the pump. Before checking or servicing the pump, follow the

Pressure Relief Procedure above to prevent the pump from starting accidentally.

2 306-743

4.

Spray gun: obtain grounding through connection to a properly grounded fluid hose and sprayer.

5.

Object being sprayed: according to local code.

6.

Fluid supply container: according to local code.

7.

All solvent pails used when flushing, according to local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity.

8.

To maintain grounding continuity when flushing or reliev­ ing pressure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.

To ground the pump, loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm 2

) minimum ground wire (Y) into the slot in the lug (Z) and tighten the locknut securely. See Fig 1. Connect the other end of the wire to a true earth ground. Refer to page 10 to order a ground wire and clamp. z

NOTE: Reference numbers and letters in paren­ theses in the text refer to the callouts in the figure illustrations and the parts drawing.

See pages 10 and 11 for accessories that are available from Graco.

The Typical Installation shown above is only a guide for selecting and installing system components. Contact your Graco representative for assistance in designing a system to suit your particular needs.

Mount the pump to suit the type of installation planned.

Be sure the pump intake is 1 /2 in. (13 mm) off the bot­ tom of the drum or pail. The pump dimensions and mounting hole layout are shown on the back cover.

-------WARNING-------

Two accessories are required in your system: a bleed-type master air valve (Al and a fluid drain valve (E). These accessories help reduce the risk of serious bodily injury including fluid injection, splashing in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trap­ ped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cy­ cle unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose and gun; triggering the gun to relieve pressure may not be sufficient.

Install the air line accessories in the approximate order shown in the Typical Installation. The pump air inlet is

3/8 npsm. Install an air line lubricator (Cl close to the pump air inlet for automatic air motor lubrication. Install a pump runaway valve (Ml shut the pump off automatically if it runs out of fluid. Install an air filter and regulator assembly (Bl to remove harmful dirt and moisture from your compressed air supply, and to regulate the air pressure to the pump. Install a bleed­ type master air valve (Al downstream from the regulator, and upstream from the lubricator, but within easy reach of the pump, to relieve air trapped between the valve and the pump.

An air line filter /regulator (Bl should also be installed on the air line to each air spray gun (Kl.

On the fluid supply line, install a drain valve (El, a surge tank (Fl to reduce line pulsations, and a fluid filter (H) with shutoff valves (G) to isolate it for cleaning.

Each fluid supply line to the air spray guns should also have a fluid regulator (J).

On each fluid return line, install a back pressure valve (L) after the last gun station, to provide constant system back pressure for all spray guns and proper pressure for fluid circulation.

Be sure all air and fluid hoses are properly sized for your system. Use only grounded air and fluid hoses.

Grounding

Proper grounding is essential to maintaining a safe system. Read FIRE OR EXPLOSION HAZARD on page 2, then ground the pump and system as explained in that section.

306-743 3

OPERATION

Flushing

Flush the supply lines and hoses with compatible solvent and blow dry with air before connecting them to the system. This is to purge any contaminants such as dirt, moisture or metal shavings that could damage the pump or system components.

Then flush the pump. The pump was tested in lightweight oil, which was left in to protect the pump from corrosion. Flush out the pump before connecting it to the system if the oil could contaminate the fluid you are pumping.

If the pump is not immersed, fill the packing nut/wet cup 1 /2 full with Graco Throat Seal Liquid or a compati­ ble solvent. Keep the cup filled at all times to help pre­ vent the fluid you are pumping from drying on the displacement rod and damaging the throat packings.

Starting the Pump (Circulating System)

1. Close the pump air regulator (Bl.

2. Open the shutoff valves on one side of the filter (H) loop.

3. Set the pump runaway valve (Ml at a high setting until after the system is operating.

4. Open the back pressure valves (L).

5. Open the bleed-type master air valves (A).

6. Slowly open the pump air regulator and allow the pump to run slowly until fluid is flowing freely from both return lines.

7. Trigger the last gun in the loop, holding a metal part of it firmly to the side of a grounded metal waste container to reduce the risk of sparking. When fluid is flowing freely, release the trigger.

8. Repeat Step 7 for all gun stations.

9. Adjust the pump runaway valve, accumulator, back pressure valves, and spray guns according to the in­ structions supplied with them.

Use an air regulator (Bl to control pump speed and fluid pressure. Always use the lowest pressure necessary to get the desired results. Higher pressures cause premature pump wear, wastes fluid, and usually does not improve the spray pattern.

-------WARNING-------.

To reduce the risk of overpressurizing your pump, which could result in component rupture and cause serious bodily injury, NEVER exceed 180 psi

(12 bar) Maximum Incoming Air Pressure to the pump. Reduce the pump pressure, if necessary, to avoid overpressurizing any other system component.

In a circulating system, the pump runs continuously and slows down or speeds up as supply demands, until the air supply is shut off.

In a direct supply system, with adequate air pressure supplied to the motor, the pump starts when the gun or dispensing valve is opened, and stalls against pressure when it is closed.

4 306-743

If the pump accelerates quickly or is running too fast, stop it immediately. Check the fluid supply and refill it if necessary. Prime the pump to remove all air from the system, or flush the pump and relieve pressure. If you have a carbon steel pump, see Corrosion Protection, below. A pump runaway valve (Ml installed on the air line to the pump will automatically shut off the pump if it is running too fast.

Auid Piston and Intake Valve Adjustment

The fluid piston and intake valves are factory set for pumping medium viscosity fluids such as spray paint.

See page 6 for how to adjust these valves for lighter or heavier viscosity fluid.

Shutdown and Care of the Pump

Always stop the pump at the bottom of its stroke to pre­ vent fluid from drying on the rod and damaging the throat packings.

-------WARNING-------.

Always follow the Pressure Relief Procedure

Warning on page 5 whenever you stop spraying and before checking or repairing any part of the system, to reduce the risk of serious bodily injury.

If you are pumping fluid which dries, hardens or sets up, flush the system with a compatible solvent as often as necessary to prevent a buildup of dried fluid in the pump or hoses.

Check the tightness of the packing nut weekly. It should be tight enough to stop leakage, but no tighter. To ad­ just the nut, first follow the Pressure Relief Pro­ cedure Warning on page 5, and then use a 1 /4 in.

(6.4 mm) dia. rod to adjust the nut.

Corrosion Protection for Carbon Steel Pumps

-------CAUTION-------.

Water, or even moist air, can cause your pump to corrode. To help prevent corrosion, NEVER leave the pump filled with water or air. After normal flushing, flush the pump again with mineral spirits or oil-based solvent, relieve pressure, and leave the mineral spirits in the pump. Be sure to follow all steps of the Pressure Relief Procedure Warn­ ing on page 5.

------WARNING------....

Pressure Relief Procedure

To reduce the risk of serious bodily injury, in­ cluding splashing in the eyes or on the skin or in­ jury from moving parts, always follow this pro­ cedure whenever you shut off the pump, when checking or servicing any part of the spray system, when installing, cleaning or changing fluid tips, and whenever you stop spraying.

1. Shut off the air to the pump.

2. Close the bleed-type master air valve (required in your system).

3. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.

4. Open the drain valve (required in your system), having a container ready to catch the drainage.

5. Leave the drain valve open until you are ready to spray again.

If you suspect that the fluid tip or hose is com­ pletely clogged, or that pressure has not been fully

relieved after following the steps above, VERY

SLOWLY loosen the hose end coupling and relieve pressure gradually, then loosen completely. Now clear the fluid tip or hose.

-------WARNING-------.

NEVER operate the air motor with the muffler plates removed. Operating the air motor with these plates removed can result in amputation if your fingers are caught in a moving part, such as the air motor piston.

Displacement Pump Repair

Before you start:

1. Be sure you have all necessary repair parts on hand to reduce down time. A packing repair kit, 206-926, is available. See page 8. Use all the new parts in the kit for the best results.

Parts which are included in the kit are marked with an asterisk in the following procedures, for exam­ ple, (21*).

2. Clean all parts thoroughly after disassembly and in­ spect them for wear or damage. Replace worn parts as necessary.

Check the balls for nicks or scratches which could prevent them from completely sealing the intake or piston valves.

Carefully inspect the outside of the displacement rod and the inside of the cylinder. Scoring or ir­ regular surfaces on these smooth, polished parts causes premature packing wear and leaking. Check the parts by holding them up to a light at a slight angle and/or by rubbing a finger on the surface.

Repair Procedure

1. Flush the pump, if possible, and then follow the

Pressure Relief Procedure Warning on page 5.

Disconnect the hoses from the pump. Unscrew the swivel (29) from the tube (12), and the lower locknut (7) from the tube (11 ). Screw the coupling nut (30) up, off the displacement rod (39).

Intake Valve

2. Remove the lower tie rod locknuts (18). Slide the in­ take valve housing (33) off the cylinder. Remove the ball stop pin (36), ball (16), seat (44) and o-ring

(21*). Take note of which hole the ball stop pin is in. Clean and inspect.

Piston

3. Pull the cylinder (37) down and off the pump hous­ ing (34).

4. Unscrew the piston seat (43). Remove all the pack­ ings. Remove one of the pins (17) and pull out the ball stop pin (40). Take note of which hole the ball stop pin is in. Clean and inspect.

5. Lubricate the packings and reassemble as follows:

Install the ball stop pin (40) and cotter pin (17*).

One at a time, stack the washer (42*), spreader

(41*), leather cup packing (26*), spacer (27), o-ring

(20*), leather cup packing (26*), spreader (41 *), and washer (42*) on the piston (43). Place the ball

(15) on the piston and screw the assembly into the displacement rod.

6. Replace the o-ring (35*) in the bottom of the pump housing (34) with a new one.

Throat Packings

7. Remove the locknuts (18) from the top of the tie plate (32). Remove the tie plate. Pull the displace­ ment rod (39) down and out of the pump housing

(34).

8. Remove all parts from the throat and clean and inspect.

9. Lubricate all parts and reassemble as follows: One at a time, install the spring (25), male gland (24*), six leather v-packings (23*) (with the lips of the packings facing down), female gland (22*) and bearing (28*) in the pump housing. Place the tie plate (32) on the throat packings.

Reassembly

10. Install the cylinder (21) in the pump housing (34).

11. Lubricate the displacement rod and packings and slide the assembly through the cylinder.

12. Install the intake valve assembly and the two lower locknuts (18). Tighten the upper and lower locknuts

(18) evenly to keep the pump balanced.

13. Position the pump mounting tubes (11, 12) on the pump housing (34). Thread the lockwasher (4) and locknut (7) onto the return tube ( 11) a few turns.

Tighten the swivel union (29) onto the supply tube

(12).

14. Butt the connecting rod (45) and displacement rod

(39) together. Adjust the return tube lock nuts (7) to align the tubes. Without losing alignment, tighten the locknuts securely. Now tighten the coupling nut securely down onto the displacement rod.

15. Connect the air supply to the motor and apply about 50 psi (3.5 bar) of air. Adjust the locknuts on the return mounting tube (11) until the pump operates smoothly on 15 psi (1 bar) or less. Tighten the nuts securely.

16. Remount the pump, and be sure to reconnect the ground wire.

Adjusting the Piston and Intake Valve

The fluid and intake valves are factory set in the middle holes for pumping medium viscosity fluids. For heavier fluids, increase the ball travel by moving the ball stop pins to a higher set of holes in the intake valve and seat

(44) and in the displacement rod (39). For very light fluids, decrease ball travel by moving the ball stop pins to a lower set of holes.

To adjust, follow the Pressure Relief Proce<ture

Warning on page 5. Then follow Steps 2 to 4 at the left, except don't remove the packings. Install the pins in a different set of holes and reassemble.
