Typical Installation

The Typical Installations shown in Figs. 2 and 3, and the following installation information are only guides. Proper sizing of the pump, accessories and lines is essential to get the maximum performance from your system. Contact your Graco distributor for assistance in designing a system to meet your needs.

Mount the Pump

This pump can be mounted on a floor stand, cart, wall bracket, or drum. The floor stand shown in the Typical Installation is Part. No. 220???581.

Instructions for mounting the pump are supplied with the mounting accessory.

Plumbing

The pump has a 1???1/2 in. npt(f) fluid inlet and a 1 in. npt(f) fluid outlet. Use a minimum 25 mm (1 in.) diame- ter pipe or hose between the pump outlet and any supply line accessories. Use a minimum 38 mm (1???1/2 in.) diameter pipe or hose between the mix tanks and pump inlet.

When using a stainless steel pump, use stainless steel plumbing to maintain a corrosion-resistant system.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE AND EXPLOSION HAZARD on page 5.

1.Pump: use the ground wire and clamp. See Fig. 1. Loosen the grounding lug locknut (W) and washer

(X). Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. For a ground wire and clamp, order Part No. 237???569.

2.Air and fluid hoses: use only electrically conductive hoses.

3.Air compressor or hydraulic power supply: follow manufacturer???s recommendations.

4.Surge tank: use a ground wire and clamp. See Fig. 1.

5.Spray gun: ground through connection to a prop- erly grounded fluid hose and pump.

6.Fluid supply container: follow your local code.

7.Object being sprayed: follow your local code.

8.Solvent pails used when flushing: follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continu- ity.

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

Air Line to Motor

5.The air filter (K) removes harmful dirt and moisture from the compressed air supply.

WARNING

A bleed-type master air valve (D) is required in your system, to help reduce the risk of serious injury including splashing fluid in the eyes or on the skin, and injury from moving parts if you are adjust- ing or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump. Order Part No. 113???333.

1.The air line lubricator (N) automatically lubricates the air motor to prevent corrosion. See Fig. 2.

2.The bleed-type master air valve (M) relieves air trapped between itself and the motor, when the valve is closed. Install one valve close to the pump, downstream from the air regulator. Install a second bleed valve upstream from all other air line accessories, to isolate the accessories for servic- ing.

3.The air regulator (L) controls pump speed.

4.The pump runaway valve (P) shuts off the air to the pump if the pump speed exceeds your pre-ad- justed setting. Running a pump too fast can dam- age it.

6.The air supply line (J) must be large enough to supply the proper volume of air to the motor.

Fluid Line from Pump

WARNING

A fluid drain valve (J) is required in your system, to help reduce the risk of serious injury including splashing in the eyes or on the skin if the pump cycles unexpectedly.

Locate one valve downstream from the pump outlet and another valve downstream from the surge tank

(G). These drain valves are used to relieve fluid pressure in the pump and surge tank during shut- down.

1.The surge tank (G) reduces fluid surging to pre- vent backflow into the pump. Mounting instructions are supplied with the tank.

2.The shutoff valves (D) before and after the surge tank, and between each mix tank and the pump fluid inlet, isolate these components for servicing.

3.Be sure the supply line (C) between the pump and mix tanks is level.

Hydraulic Power Supply

CAUTION

The Hydraulic Power Supply must be kept clean at all times to avoid damage to the motor and hydraulic power supply.

1.Blow out hydraulic lines with air and flush thor- oughly before connection to the motor.

2.Plug hydraulic inlets, outlets, and line ends when disconnecting them for any reason.

1.Be sure the power supply can provide sufficient power to the motor.

2.Be sure the power supply is equipped with a suction filter to the hydraulic pump.

Hydraulic Supply to Motor

NOTE: The motor???s hydraulic inlet is 3/4 in., 37_ flare. Use a minimum 13 mm (1/2 in.) ID hydraulic supply line (L).

1.The shutoff valve (R) isolates the motor when servicing the system. See Fig. 3.

2.The hydraulic fluid pressure gauge (Q) monitors the hydraulic oil pressure to the motor. This helps avoid overpressurizing the motor or displacement pump.

3.The pressure- and temperature-compensated flow control valve (S) prevents the motor from running too fast, which can damage it.

4.The pressure reducing valve (P) which has a drain line (M) running to the return line (K), controls the hydraulic pressure to the motor.

Hydraulic Return from Motor

NOTE: The motor???s hydraulic outlet is 7/8 in., 37_ flare. Use a minimum 16 mm (5/8 in.) ID hydraulic return line (K).

1.The shutoff valve (R) isolates the motor when servicing the system.

CAUTION

To avoid damage to the pump, never use the return line shutoff valve to control the hydraulic flow. Do not install any flow control devices on the hydraulic re- turn line.

2.The 10 micron size return filter (J) removes resi- due from the hydraulic fluid to help keep the sys- tem running smoothly.

Fluid Line from Pump

WARNING

A fluid drain valve (J) is required in your system, to help reduce the risk of serious injury including splashing in the eyes or on the skin if the pump cycles unexpectedly.

Locate one valve downstream from the pump outlet and another valve downstream from the surge tank

(G). These drain valves are used to relieve fluid pressure in the pump and surge tank during shut- down.

1.The surge tank (G) reduces fluid surging to pre- vent backflow into the pump. Mounting instructions are supplied with the tank.

2.The shutoff valves (D) before and after the surge tank, and between each mix tank and the pump fluid inlet, isolate these components for servicing.

3.Be sure the supply line (C) between the pump and mix tanks is level.

Before You Start the Pump

Read and follow all instruction manuals, labels and tags supplied with this pump and with all the accesso- ries you add to the system, before operating the sys- tem.

Flush the Pump Before First Use

The pump was tested in lightweight oil. If the oil will contaminate the fluid you are pumping, flush it out with a compatible solvent.

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying acci- dentally. To reduce the risk of an injury from acci- dental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Proce- dure whenever you:

Dare instructed to relieve the pressure,

Dstop spraying,

Dcheck or service any of the system equipment,

Dor install or clean the spray nozzle.

1.Shut off the power to the pump.

2.In an air-powered system, close the air regulator and close the bleed-type master air valve.

3.In a hydraulic-powered system, close the hy- draulic supply line shutoff valve first, then the return line shutoff valve. In a multi-pump system, do this at each pump to isolate the pumps.

4.Close the fluid shutoff valves from the supply tanks.

5.Trigger the gun at the last gun station to relieve fluid pressure. Maintain firm metal-to-metal contact between the gun and a grounded waste pail. Repeat for all gun stations.

6.Open the pump drain valve to relieve fluid pres- sure which may be trapped in the pump or hose.

If you suspect that pressure is not fully relieved after following the steps above, wrap a fitting near the pump outlet with a rag, and slowly and carefully loosen the fitting to relieve pressure. Be careful to protect your eyes from splashing.

Starting and Adjusting the Pump

1.Charge the surge tank, if you are using one. See the separate instruction manual, 307???707.

2.Open all shutoff valves (D).

3.Open the dispensing valve/spray gun at the last gun station and keep it open while starting the pump.

4.Open the bleed-type master air valves (M).

5.Adjust the air regulator (L) to the minimum pres- sure necessary for the pump to cycle slowly.

6.When fluid is flowing smoothly from the gun, release the gun trigger.

7.One at a time, open any other guns in the system to purge air from the lines.

8.Adjust the pump runaway valve (P) according to the instructions supplied with it.

9.Adjust the lubricator (N) according to the instruc- tions supplied with it.

NOTE: In a circulating system, the pump operates continuously until the power supply is shut off. In a direct supply system, the pump starts when the gun/ valve is opened, and stops when the gun/valve is closed. The pump always stops on the downstroke due to the vented inlet seat (32).

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing your system, which could cause

component rupture and serious injury, never exceed the specified maximum air input pressure to the pump (see Technical Data on pages 40???45).

Shutdown

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 12.

Relieve the pressure.

Starting and Adjusting the Pump

1.Charge the surge tank, if you are using one. See the separate instruction manual, 307???707.

2.Open all shutoff valves (D).

3.Turn on the hydraulic power supply.

4.Open the flow control valve (S) all the way.

5.Open the return line shutoff valve first, then open the supply line shutoff valve.

6.Open the dispensing valve/spray gun at the last gun station and keep it open while starting the pump.

7.Adjust the pressure reducing valve (P) until you get the desired fluid pressure.

8.When fluid is flowing smoothly from the gun, release the gun trigger.

9.One at a time, open any other guns in the system to purge air from the lines.

10.With a gun triggered open (dead-end systems only) or with the pump running in a circulating system, count the cycle rate of the pump for one minute. Close the flow control valve (S) until the cycle rate drops to below the desired cycle rate.

11.Open the flow control valve (S) slowly until the cycle rate and fluid pressure return to the desired level. This method of setting the hydraulic controls ensures proper pump operation and prevents pump runaway and damage if the fluid supply runs dry.

12. Release the gun trigger.

NOTE: In a circulating system, the pump operates continuously until the power supply is shut off. In a direct supply system, the pump starts when the gun/ valve is opened, and stops when the gun/valve is closed. The pump always stops on the downstroke due to the vented inlet seat (32).

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing your system, which could cause

component rupture and serious injury, never exceed the specified maximum hydraulic input pressure to the pump (see Technical Data on page 46).

Shutdown

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 12.

Relieve the pressure.

Always shut off the supply line shutoff valve first, and then the return line shutoff valve. This is to prevent overpressurizing the motor or its seals.

The operating conditions of your particular system determine how often maintenance is required. Estab- lish a good maintenance schedule during the first several weeks of operation by recording when and what kind of maintenance is needed, and then deter- mine a regular schedule for checking your system. Your maintenance schedule should include the follow- ing:

Flushing

WARNING

FIRE AND EXPLOSION HAZARD

Before flushing, read the section FIRE AND EXPLOSION HAZARD on page 5. Be sure the entire system and flush- ing pails are properly grounded. Refer to

Grounding on page 7.

1.Flush before shutting down the system for an extended period of time.

2.Flush before repairing the pump, if possible.

3.Flush before the fluid you are pumping can dry out, settle or set up in the pump and hoses.

Packing Nut Tightness

The packing nut (21) should be tight enough to stop leakage, but no tighter. Overtightening compresses and damages the packings, and may cause the pump to leak, reducing performance. See Fig. 4.

To check the adjustment of the packing nut, first re- lieve fluid pressure. If you have a torque wrench, tighten the packing nut to 34???40 NSm (25???30 ft???lb).

Excessive Leaking at Throat

To monitor leaking at the throat, remove one of the small plugs (31) from the packing nut (21). Place one end of a drain tube in the hole and the other end in a container. See Fig. 4. Monitor the drainage. If it seems excessive, and tightening the packing nut does not help, replace the throat packings. See page 20.

Air Line Filter

Drain and clean as necessary.

Hydraulic Power Supply Check

Carefully follow the hydraulic power supply manufac- turer???s recommendations on reservoir and filter clean- ing, and periodic changes of hydraulic fluid.

Stop the Pump at the Bottom of Its Stroke

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 12.

Whenever you stop the pump for any reason, relieve the pressure. Stop the pump on the downstroke, before the air motor changes over. If the pump is stopped on the upstroke a pressure relief seat causes the piston to creep until it reaches the up position. Following the Pressure Relief Procedure helps stop the pump at the bottom of its stroke.

Mix Tank Volume

Don???t let the mix tank run dry. When the tank is empty, the pump demands more power as it tries to suck in some fluid. This causes the pump to run too fast, which can seriously damage the pump.

CAUTION

Failure to stop the pump at the bottom of its stroke allows fluid to dry on the piston rod, which can cause damage to the throat packings when the pump is restarted.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 12.

1.Relieve the pressure.

2.Check all possible problems and solutions before disassembling pump.

Disconnecting the Displacement Pump

NOTE: In stand or wall-mounted installations, you do not have to remove the entire pump from its mounting.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 12.

1.Relieve the pressure.

2.Disconnect the hoses from the displacement pump and plug the ends to prevent fluid contamination.

3.Disconnect the displacement pump from the motor as follows:

Repair Kits

A pump seal kit is available for each pump size. Throat packing kits are also available, one for UHMWPE/ leather pumps and one for PTFE pumps. The piston seals may also be converted to PTFE. Refer to page 36 for ordering.

Parts supplied in the pump seal kit are marked with one asterisk in the text and drawings, for example (2*). Parts supplied in the throat packing kit are marked with a symbol, for example (19{). For the best results, use all the parts in the kit.

Disassembling the Displacement Pump

1.Remove the pump from the motor as explained on page 18.

2.Secure the displacement pump intake housing (10) in a vise.

3.Refer to Fig. 9. Remove the four capscrews (9) and washers (8) from around the pump outlet housing (22).

4.Remove the outlet housing (22), balls (23), seats

(24)and gaskets (7).

5.Remove the three tie bolts (13) and lockwashers

(14).Lift off the upper pump housing (1), along with the fluid tubes (3), cylinder (4), and piston assembly (16).

6.Remove the packing nut (21), glands (19, 26) and packings (20, 25) from the upper housing (1).

NOTE: Model 237???220 and 237???221 displacement pumps use 5 PTFE v-packings in the throat, instead of 3 UHMWPE (20) and 2 leather (25).

7.Remove the tubes (3) and cylinder (4) from the housing.

8.Remove the intake housing (10) from the vise.

9.Remove the four capscrews (9) and washers (8) from the intake housing (10). Use a flatblade screwdriver inserted between the lower pump housing (11) and the intake housing (10) to sepa- rate the parts.

10.Remove the balls (5), seats (6 and 32) and gas- kets (7).

NOTE: One of the seats (32) has a vent hole. Take note of the side of the pump in which this seat is used (the left side when viewed as shown in Fig. 9).

WARNING

COMPONENT RUPTURE HAZARD

The vented ball seat (32) must be in- stalled at the fluid inlet. This valve

relieves pressure trapped in the pump cylinder when the pump is shut off, and reduces the risk of pump overpressurization. The seat cannot relieve pressure if installed in any other position.

NOTE: Inspect the parts of the piston assembly (items 12, 15 and 16) in place before disassembling the piston. The piston seal (15) is included in the Seal Repair Kit. If it or any other parts of the piston show wear or damage, proceed to step 11. If no damage is apparent, it is not necessary to disassemble the piston.

11.Place the flats of the piston nut (12) in a vise. Unscrew the rod (17) from the nut. Disassemble the two halves of the piston (16) and remove the seal (15).

Cleaning and Inspecting Parts

Clean all parts in a compatible solvent. Inspect all parts for wear or damage. If you are using a repair kit, use all the new parts in the kit, discarding the old ones they replace. Replace any other parts as needed. Worn or damaged parts may cause the pump to per- form poorly or cause premature wear of the new seals and packings.

2.Apply thread sealant to the piston rod (17) threads. Screw the rod through the piston and packings and into the special piston nut (12). Torque the nut to 68???81 NSm (50???60 ft-lb).

3.With the lower pump housing (11) turned upside down, install the balls (5). Install the seats; place the vented seat (32) in the left side as viewed in Fig. 9 (housing has a label to identify the correct side), and the non-vented seat (6) in the right side. Install the gaskets (7*).

NOTE: The seats (6 and 32) are not reversible; the chamfered side must face the ball.

4.Place the intake housing (10) on the lower pump housing (11). Install the lockwashers (8) and capscrews (9). Torque to 34???40 NSm (25???30 ft-lb). See Fig. 10.

5.Place the intake housing (10) in a vise. Place one o-ring (2*) in each side of the lower pump housing (11) where the tubes (3) sit. Place anoth- er o-ring (2*) in the grooves at each end of the tubes. Place a gasket (18*) in both the upper and lower housings (1 and 11). Position the tubes and cylinder (4) in the lower housing (11).

6.Lubricate the inside of the cylinder (4). Slide the piston assembly into the cylinder.

7.Lubricate the throat packings and glands.

Install them one at a time in the throat of the upper pump housing (1). Make sure the lips of the v- packings face down into the housing, and use a finger to seat the parts: the male gland (19{), one UHMWPE packing (20{), one leather packing (25{), UHMWPE, leather, UHMWPE, and the female gland (26{). Install the packing nut (21) finger-tight.

NOTE: Model 237???220 and 237???221 displacement pumps use 5 PTFE v-packings in the throat, instead of 3 UHMWPE (20) and 2 leather (25).

8.Install the upper pump housing (1). It may not seat well on the tubes and cylinder. Apply thread sea- lant to the threads of the three tie bolts (13). Install the bolts and lockwashers (14) from the lower pump housing (11). As you tighten the bolts into the upper housing (1), they will draw the housings firmly onto the tubes and cylinders. Tighten the bolts uniformly and torque to 34???40 NSm (25???30 ft-lb).

9.Torque the packing nut (21) to 68???74 NSm (50???55 ft-lb).

10.Place a ball (23), seat (24) and gasket (7*) in each side of the outlet housing (22). Install the outlet housing on the upper pump housing (1). Note that the flatter side of the housing faces the outside edge of the pump. Install the lockwashers (8) and screws (9), and torque to 34???40 NSm (25???30 ft-lb).

CAUTION
