Grounding
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 injury and property damage.
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.
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. 2, page 6.
System Design
The Typical Installation shown on page 4, 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 Graco (see back page) for further information.
Pump dimensions and the mounting hole layout are shown on page 24. The Technical Data is given on page 29.
Remove burrs, dirt and contaminants from the ends of the tubes before installing the fittings.
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.
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.
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.
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 correctly rated for the operating pressure.
Fluid Filters
Install two fluid filters (P) with line isolation valves (Q) on each side. This allows the system to be used while cleaning a filter.
308060 5
Installation
Mounting the Pump
Secure the pump, without the motor, in the pump standpipe (V), using the bolts provided.
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.
CAUTION
Do not flush the pump with any acid, caustic or abrasive flush solution (line stripper) of any type. The pump is designed to circulate automotive paint coatings only.
Place the motor coupler (29) on the motor shaft (A), pushing it up, well beyond the end of the shaft. Lightly snug the setscrew (B).
Lower the motor onto the pump base, making sure the motor locating flange seats properly on the pump base.
Loosen the motor coupler setscrew (B). Pull the coupler (29) 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. 2. Tighten the pump coupler setscrew.
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).
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. 2.
CAUTION
1.
Before operating the pump, turn the motor coupler by hand to be sure the shaft rotates freely in the correct direction. 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
2.
Starting the pump
(Always use this procedure to start the pump)
CAUTION
The pump is designed for continuous operation.
Regular shutdown at night or on weekends may cause premature bearing wear and invalidate the warranty.
Do not 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.
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.
Flushing and Priming System
(See the Typical Installation and Fig. 2.)
The procedure given here is for a stand-mounted pump, two mix tank system as shown in the Typical
Installation on page 4. 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.
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.
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. 2.
2.
If the motor labors or the pump does not 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 repair check of the drive coupler clearance.
3.
Be sure the circulating lines are flushed and primed with fluid as instructed below. Do not flush the pump with any acid, caustic or abrasive flush solution (line stripper) of any type. The pump is designed to circulate automotive paint coatings only.
1.
Preparing to flush 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.
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 flushing a.
Continue circulating the solvent, changing the solvent as needed until the system is thoroughly flushed.
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).
308060 7
Operation
8.
Flushing paint from system 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.
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.
CAUTION
Do not flush the pump with any acid, caustic or abrasive flush solution (line stripper) of any type. The pump is designed to circulate automotive paint coatings only.
CAUTION
De-ionized (D.I.) water is an agressive, corrosive material. It can be used on the wateborne versions of the Imperial Pumps. Exposure of all other Imperial
Pumps to D.I. water should be minimized, and the
D.I. water should be flushed from the pump with a non-corrosive material such as alcohol.
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.
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 on page 4 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 Replace-
ment, page 12, for proper adjustments.
8 308060
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. 3.
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.
CAUTION
Do not over grease the bearing, which may cause the bearing to overheat. Remove any excess grease after lubricating.
Preventive
Maintenance
Thrust Bearing. Once a month, lubricate the thrust bearing if pump is run continuously. Refer to thrust bearing Lubrication instructions on this page. It is recommended that the Imperial pump thrust bearing assembly be replaced at least once a year.
Pump Pressure, Flow, and Temperature. Once a month, check the static discharge pressure, flow rate of the pump, thrust bearing temperature, and coupler clearance. Record them.
NOTE: If the operating temperature exceeds 150 F
(65 C) and normal maintenance, troubleshooting, and service fails to reduce temperature, contact a qualified
Graco representative.
CAUTION
Blockage of the overflow tube and overflow chamber on pump base will cause leakage through the shaft seal and adjustment nut opening.

TROUBLESHOOTING CHART IS CONTINUED ON PAGE 11.
* Before removing the pump for cleaning, close the check valve (J) or line isolation valves (Q) and note the maximum pump pressure; the pressure should be steady. Do not leave valves closed for more than 10 seconds.
If pressure variations or pulsations are noted, the problem could be 1.) a clogged intake, 2.) too low a fluid level in the tanks, or 3.) restricted plumbing.
Correct the clogged condition to obtain steady pressure.
Low pressure can also be caused by air entrainment in water reducible fluids. All return lines in tanks with water reducible fluid must be routed to the bottom of the tank.
Be careful to avoid allowing deteriorated pieces of bag filters into the pump which can result in serious damage to the pump.

c.
Remove the collet (18) and impeller (30). Do not pry the impeller.
d.
Remove all of the impeller bowl assemblies in this way.
6.
Inspect the shaft (33) for scoring or wear and replace it, if needed. Check all bowls and impellers for wear or damage and replace as needed. Install new o-rings (9) on all impeller bowls (37b) and the intake bowl (36a), then lubricate the o-rings in place. Be sure the impeller nuts (32) rotate freely on the collets.
7.
To replace the bearings: a.
Use the short-nippled end of tool 177219 to press out the bearings (37a) from all bowls
(37b) and the intake bowl (36a). See Fig. 10.
b.
Use the long-nippled end of the tool to press new bearings (36b, 37a) into the bowls. This tool maintains the required 0.06 in. (1.6 mm) dimensions of the impeller bowls as shown in
Fig. 10.

Graco Standard Warranty
Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract, breach of warranty, the negligence of Graco, or otherwise.
