WARNING

KEEP CLEAR OF MOVING OR

HEATED PARTS

Keep your fingers and hands away from the moving parts in the pump housing while the pump is operating to reduce the risk of amputation.

Keep all tools, etc. away from the moving parts to reduce the risk of accidentally catching and breaking them in the moving parts, which could cause broken pieces to be projected into the air and cause serious bodily injury as well as pump damage.

GROUNDING AND ELECTRICAL WIRING

Be sure the pump, the object being sprayed, and all related equipment is properly grounded to reduce the risk of static sparking, which can cause electric shock, fire or explosion and result in serious bodily injury and property damage.

Have a qualified, licensed electrician perform all wiring and grounding in accordance with all applicable safety codes in your area.

Consult the electric motor manufacturer for the proper heater-breaker requirements.

Always shut off all electrical power to the pump before servicing or adjusting the pump to reduce the risk of electric shock and serious injury from moving parts.

Before removing the pump for repair, shut off the electrical power and relieve the system pressure to reduce the risk of serious bodily injury from shock, moving parts, or pressurized fluid.

SYSTEM PRESSURE

Never operate the pump at more than 250 psi (17 bar)

MAXIMUM WORKING PRESSURE to reduce the risk of component rupture, which could result in serious bodily injury and property damage and cause premature bearing and seal failure.

The pump housing and pump shaft couplers become heated during operation. To reduce the risk of burning yourself, do not touch them until they have cooled.

INSTALLATION

WARNING

Ground the pump in accordance with all applicable safety codes in your area. Proper grounding reduces the risk of shock, fire or explosion caused by static sparking, which can result in serious bodily injury and property damage.

Return Line

Install a back pressure valve (F) to maintain proper line pressure to all outlets. Install a flow meter (G) to visually check the fluid flow rate.

Extend the return line (E) going into the mix tank (B) to the bottom of the tank and end it with an elbow (A). The elbow directs fluid around the walls of the tank to help minimize air entrainment in the fluid.

1. Have a licensed electrician complete the electrical hookup and wiring.

2. Consult the electric motor manufacturer for proper heater-breaker requirements.

3. Before coupling the pump coupler to the motor shaft coupler, check to be sure the shaft rotates in the proper direction. Refer to Fig 1, page 4.

NOTE: This pump is designed for systems with mix tanks of a maximum 60 inches (1.5 m) height.

Supply Line

Install a line check valve (J) near the 2 in. npt(f) pump outlet.

CAUTION

The line check valve (J) is required to prevent fluid backflow into the pump in case of a power failure or incorrect operating procedure.

System Design

The Typical Installation shown on page 2, and the following text, is only a guide to show the relationship of the pump to other system components. Due to the pressure characteristics of the pump, which vary widely with viscosity and specific gravity, professional systems design is essential. Contact an application engineer at one of the following locations for assistance:

Graco Detroit (313) 471–0500

Graco Chicago (312) 678–7200

Graco Minneapolis (800) 543–0339

Pump dimensions and the mounting hole layout are shown on page 22. Accessories are shown on page 23.

The Technical Data is given on the back cover.

Install a pressure gauge (G) at the plugged 1/2 npt(f) port at the left of the pump outlet. Make sure the gauge is corrected sized for the operating pressure.

Fluid Filters

Install two fluid filters (U) with line isolation valves (Q) on each side. This allows the system to be used while cleaning a filter.

Mounting the Pump

Secure the pump, without the motor , in the pump standpipe (V), using the bolts provided.

Fluid Lines

Line sizes depend on the flow requirements and calculated pressure drop due to the length of the run.

The pipe, tubing and fittings must be compatible with the fluid and solvent you plan to use.

Keep in mind that sharp corners and fittings between lengths of pipe or tubing may cause flow restrictions and fluid breakdown. Use the longest lengths of pipe or tubing available to minimize couplings. Use the most direct route to the spray stations, and whenever practical, use long sweeping bends. A “holsclaw” bender is recommended for making bends in tubing; a common electrician’s or plumber’s bender is not satisfactory.

Remove burrs, dirt and contaminants from the ends of the tubes before installing the fittings.

Be sure the pump inlet and the plumbing to the mix tanks are at the same level. Install the necessary plumbing, using shims as necessary. Then bolt the pump standpipe and the tanks securely to the floor.

After All Lines Are Installed

Flush all lines with a compatible solvent and blow out with air. Then clean the elements of the filters (P).

(Installation continued on page 4)

INSTALLATION

Installing the Motor

Remove the protective cover and the shipping dowel from the pump base (31). Remove the motor coupler

(29).

When wiring the motor, be sure the shaft rotates in the direction shown on the pump base and in Fig 1.

Place the motor coupler on the motor shaft (A), pushing it up, well beyond the end of the shaft. Lightly snug the setscrew.

Lower the motor onto the pump base, making sure the motor locating flange seats properly on the pump base.

Loosen the motor coupler setscrew . Pull the coupler down to engage with the pump coupler (58) and coupling insert (6).

Adjust the motor coupler to 0.094 in. (2.39 mm) clearance. See Fig 1. Tighten the pump coupler setscrew.

CAUTION

1. Before operating the pump, turn the motor coupler by hand to be sure the shaft rotates freely.

Then recheck the 0.094 in. (2.39 mm) coupler clearance.

2. The pump is factory–set to deliver maximum outlet pressure. Do not tamper with this adjustment as it could cause damage to the impellers and bowls and void the warranty.

3. Never leave any contaminants, nuts, bolts, rags, etc., in the fluid tank or supply lines as they could seriously damage the impellers or bowls.

OPERATION

CAUTION

This pump is designed for continuous operation.

Regular shutdown at night or on weekends may cause premature bearing wear and invalidate the warranty.

Don’t let the pump run dry . Operating the pump for more than 10 seconds without fluid circulating through it will overheat the pump and damage it.

Cleaning, Flushing and Priming System

(See the Typical Installation and Fig 1.)

The procedure given here is for a standpipe–mounted pump, two mix tank system as shown in the TYPICAL IN-

STALLATION. Some specific instructions may not apply to other systems; consult your plant’s flushing procedures.

Flushing is important; it cleans all equipment and lines of impurities. Following these instructions will help assure satisfactory operation with quality control.

4

CAUTION

1. Be sure the motor rotates in the correct direction and the drive coupler clearance is set at

0.094 in. (2.39 mm). See Fig 1.

2. If the motor labors or the pump doesn’t run smoothly, check the motor for high amp draw and check the thrust bearing for overheating.

The normal operating temperature is from 120 _ to 150 _ F (49 _ to 65 _ C). If the temperature is higher than 150 _ F (65 _ C), consult a qualified

Graco representative after a repeat check of the drive coupler clearance.

3. Be sure the circulating lines are flushed clean and primed with fluid as instructed below.

1. Preparing to clean the inside of the mix tanks a. Close the outlet valves (W) of both tanks.

b. Pour about 100 gallons (380 liters) of the appropriate solvent into each tank.

c. Open the outlet (W) and return valves (K) on one tank only.

OPERATION

2. Starting the pump

(Always use this procedure to start the pump) a. Close the isolation valves (Q) on one filter.

b. Use the valve (Q) in front of the other filter to control the pump flow to 50 psi (3.5 bar) until the lines are full. Then completely open the valve.

c. Run the pump for several minutes, and then shut off the pump.

d. Recheck the drive coupler for 0.094 in.

(2.39 mm) clearance.

CAUTION

The pump coupler and bearing could move up during shipment and then, when the pump is operated, it could move down, leaving too much clearance.

This could damage both the coupler insert and the coupler.

3. Checking the system for leaks a. Restart the pump and check the entire system for leaks.

b. Tighten leaking joints as necessary.

c. Periodically check for leaks during flushing.

4. Continue cleaning a. Continue circulating the solvent, changing the solvent as needed until the system is thoroughly cleaned.

b. When the system is clean, stop the pump.

c. Drain all filtered residue from the filters (P).

d. Reconnect the return line (E) to the back pressure valve (F).

e. Close the outlet (W) and return valves (K) for the tank being used and open the outlet and return valves for the other tank.

f.

Start the pump and circulate the solvent for at least one hour.

g. While circulating, open the spray gun at each drop and flush the hoses with about one gallon

(4 liters) of solvent.

5. When flushing is complete a. Stop the pump and drain all solvent from the tanks and lines.

b. Open the filter drain valves (R) to flush out all filtered residue.

c. Thoroughly blow out the entire system with clean, dry compressed air , or nitrogen, to remove all solvent from the system.

6. Pumping paint a. Fill a tank with paint and start the agitator (C).

b. Start the pump.

c. Use the filter isolation valve (Q) to control the pump flow to 50 psi (3.5 bar) until the lines are full, and then open the valve completely.

d. Circulate the paint until all air is removed from the fluid lines.

e. While the paint is circulating, check and adjust the viscosity as necessary.

7. Filling standby tank a. Fill the other mix tank (standby tank) with paint and start the agitator.

b. Leave the agitator running so that paint in the standby tank will be ready for use when needed.

c. To keep air out of the system, always switch to the standby tank before the paint supply in the tank you have been using is completely exhausted.

8. Flushing paint from system

Consult the paint supplier for a compatible solvent for flushing paint from the system. Water reducible paints should use de-ionized water and a solvent which will keep resin in the solution. If water reducible paint has a

20% solvent content, the flush media should also contain approximately 20% solvent.

Adjusting System Pressure

Use the back pressure valve (F) to adjust the system pressure.

Determine the line pressure required. Then, with paint circulating in the line loop only , set the back pressure valve so that the pressure at the last spray gun is 10 psi

(0.7 bar) greater than needed.

Refer to the TYPICAL INSTALLATION drawing on page

2 and the separate back pressure valve instructions.

CAUTION

The pump is set at the factory to deliver the maximum volume and outlet pressure. The pressure cannot be increased by any adjustment of the pump. Refer to Pump Thrust Bearing and Seal

Replacement, page 8, for proper adjustments.

5

LUBRICATION

Lubricate the thrust bearing once a month if the pump is operating continuously. To lubricate the bearing, pump one or two shots (about 0.1 oz/2.8 grams) of Chevron

SRI/No. 2 NLGI grade grease through the fitting on the top of the seal retainer . A 14 oz. tube of this grease is supplied with the pump. See Fig 2.

NOTE: Do not lubricate the bearing when you first receive the pump as it is factory greased.

CAUTION

Use only Chevron SRI/No. 2 NLGI grade grease to help prevent bearing overheating and premature bearing failure. This green or brown-colored grease is used for the factory pack and must not be mixed with any other type of grease. The use of any other type of grease will void the Graco Warranty.

GREASE

HERE

CAUTION

Do not over grease the pump, which may cause the bearing to overheat. Remove any excess grease after lubricating.

TROUBLESHOOTING

CAUTION

When checking the pump pressure, DO NOT leave the check valve (J) or isolation valves (Q) closed for more than 10 seconds while the pump is operating to avoid overheating the pump and damaging the seals and bearings.

NOTE: Graco offers a rebuild program on all Imperial and Crown Imperial pumps. Contact your local sales representative for details.
