Installation

General Information

NOTE: Reference numbers and letters in parentheses

in the text refer to the callouts in the figures and the parts drawings.

NOTE: Always use Genuine Graco Parts and Accessories, available from your Graco distributor. Refer to the Product Data Sheet, Form No. 305546. If you supply your own accessories, be sure they are adequately sized and pressure-rated to meet the system’s requirements.

Fig. 1 is only a guide for selecting and installing system components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

System Accessories

WARNING

A red-handled main air bleed valve (V), pump air bleed valve (G), and fluid drain valve (L) are required. These accessories help reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The red-handled main air bleed valve (V) shuts off and relieves the air to the pump and ram. Order Part No. 113269 for Monark and President Pumps, or 113218 for Senator and Bulldog Pumps. The ram will hold pressure if the ram director valve (U) is in the horizontal (neutral) position. To relieve air pressure in the ram, close the red-handled bleed valve (V) and move the director valve (U) to DOWN. The ram will slowly drop.

The pump air bleed valve (G) relieves air trapped between it 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.

The fluid drain valve (L) assists in relieving fluid pressure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient. Order Part No. 210658 (3/8 npt).

Air Line

Install the following accessories as shown in Fig. 1, using adapters as necessary:

D A red-handled main air bleed valve (V) is re-

quired in your system to shut off the air supply to the pump and ram (see the WARNING at left). When closed, the valve will bleed off all air in the ram and pump, and the ram will slowly drop. Be sure the valve is easily accessible from the pump, and is located upstream from the air manifold (D).

D The pump air bleed valve (G) is required in your

system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING at left). Be sure the valve is easily accessible from the pump, and is located downstream from the air regulator (H).

D The pump air regulator (H) controls pump speed

and outlet pressure by adjusting the air pressure to the pump. Locate the regulator close to the pump, but upstream from the pump air bleed valve (G).

D An air line lubricator (F) provides automatic air

motor lubrication.

D A pump runaway valve (E) senses when the

pump is running too fast and automatically shuts off the air to the motor. A pump which runs too fast can be seriously damaged.

D An air manifold (D) has a swivel air inlet. It has

ports for connecting lines to air accessories, such as the ram air regulator (T), which controls the air pressure to the ram.

D The air pressure relief valve (Q) limits the air

pressure to the ram to 10 bar (150 psi).

D The ram director valve (U) controls the raising

and lowering of the ram.

D An air line filter (J) removes harmful dirt and

moisture from the compressed air supply. Also, install a drain valve (W) at the bottom of each air line drop, to drain off moisture.

D A bleed-type air valve (K) isolates the air line

accessories for servicing. Locate upstream from all other air line accessories.

6 308017

Installation

Fluid Line Accessories

Install the following accessories in the positions shown in Fig. 1, using adapters as necessary:

D Install a fluid drain valve (L) in a tee near the

pump fluid outlet. The drain valve is required in your system to relieve fluid pressure in the displacement pump, hose and gun/valve (see the WARNING on page 6). Install with the drain valve pointing down, but so the handle points up when the valve is open.

D A fluid regulator (M) controls fluid pressure to the

gun/valve, and dampens pressure surges.

D A gun or dispense valve (N) dispenses the fluid.

The gun shown in Fig. 1 is a high pressure dispensing gun for highly viscous fluids.

D A gun/valve swivel (P) allows freer gun/valve

movement.

Air and Fluid Hoses

Be sure all air hoses (S) and fluid hoses (R) are properly sized and pressure-rated for your system. Use only electrically conductive hoses. Fluid hoses must have spring guards on both ends.

Operation

Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from

starting or dispensing accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

D are instructed to relieve the pressure, D stop spraying/dispensing, D check or service any of the system equipment, D or install or clean the spray tip/nozzle.

1. Lock the gun/valve trigger safety.

2. Close the pump’s bleed-type air valve (G, required in your system).

Packing Nut/Wet-Cup

Before starting, fill the packing nut (2) 1/3 full with Graco Throat Seal Liquid (TSL) or compatible solvent. See Fig. 3.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left.

The packing nut is torqued at the factory and is ready for operation. If it becomes loose and there is leaking from the throat packings, relieve pressure, then torque the nut to 45–53 NSm (33–39 ft-lb) using the supplied wrench (110). Do this whenever necessary. Do not overtighten the packing nut.

Bleed hole must face down.

Torque to 45–53 NSm (33–39 ft-lb).

3. Shut off the red-handled main air bleed valve (V, required in your system). If the pump is mounted on a ram, set the ram director valve (U) to DOWN. The ram will slowly drop.

4. Unlock the gun/valve trigger safety.

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

6. Lock the gun/valve trigger safety.

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

8. Leave the drain valve open until you are ready to spray/dispense again.

110

If you suspect that the spray tip/nozzle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly

loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip/nozzle or hose.

Operation

Flush the Pump Before First Use

The pump is tested with lightweight oil, which is left in to protect the pump parts. If the fluid you are using may be contaminated by the oil, flush it out with a compatible solvent. See Flushing on page 11.

Starting and Adjusting the Pump

WARNING

MOVING PARTS HAZARD

See Fig. 3. The priming piston (25) and the air motor piston (located behind the air motor plates, AA) move during operation.

Keep hands and fingers away from the priming piston (25) during operation and whenever the pump is charged with air. The priming piston extends beyond the intake cylinder (23) to pull material into the pump and can amputate a hand or finger caught between it and the intake cylinder. Follow the Pressure Relief Procedure on page 9, before checking, clearing, or cleaning the priming piston.

Never operate the pump with the air motor plates (AA) removed.

1. Do not install the spray tip yet.

6. Slowly open the air regulator (H) until the pump starts.

7. Cycle the pump slowly until all air is pushed out and the pump and hoses are fully primed.

8. Release the gun/valve trigger and lock the trigger safety. The pump should stall against pressure.

WARNING

SKIN INJECTION HAZARD

To reduce the risk of fluid injection, do not use your hand or fingers to cover the bleed hole on the underside of the bleeder valve body (43) when priming the pump. Use a crescent wrench to open and close the bleeder plug (35). Keep your hands away from the bleed hole.

9. If the pump fails to prime properly, open the bleeder valve plug (35) slightly. Use the bleed hole on the underside of the valve body (43) as a priming valve until the fluid appears at the hole. See Fig. 3. Close the plug (35).

NOTE: When changing fluid containers with the hose and gun/valve already primed, open the bleeder valve plug (35) to help prime the pump and vent air before it enters the hose. Close the plug when all air is eliminated.

2. Supply fluid to the pump, per the requirements of your system.

3. See Fig. 1. Close the pump air regulator (H).

4. Open the red-handled main air bleed valve (V) and the pump’s bleed-type air valve (G).

5. Hold a metal part of the gun/valve (N) firmly to the side of a grounded metal pail and hold the trigger open.

CAUTION

Do not allow the pump to run dry. It will quickly accelerate to a high speed, causing damage. If your pump is running too fast, stop it immediately and check the fluid supply. If the container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.

10 308017

Operation

Starting and Adjusting the Pump (continued)

10. With the pump and lines primed, and with adequate air pressure and volume supplied, the pump will start and stop as you open and close the gun/valve. In a circulating system, the pump will speed up or slow down on demand, until the air supply is shut off.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 9.

11. Relieve the pressure. Install the spray tip in the gun.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing your system, which could cause component rupture and serious injury, never

exceed the Maximum Incoming Air Pressure to the pump (see the Technical Data on pages 33–43).

Flushing

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, read the section FIRE AND EXPLOSION HAZ- ARD on page 5. Be sure the entire system and flushing pails are properly grounded. Refer to Grounding on page

Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system. Check with your fluid manufacturer or supplier for recommended flushing fluids and flushing frequency. Always flush the pump before fluid dries on the displacement rod.

CAUTION

Never leave water or water-base fluid in the pump overnight. If you are pumping water-base fluid, flush with water first, then with a rust inhibitor such as mineral spirits. Relieve the pressure, but leave the rust inhibitor in the pump to protect the parts from corrosion.

12. Use the air regulator (H) to control the pump speed and the fluid pressure. Always use the lowest air pressure necessary to get the desired results. Higher pressures cause premature tip/nozzle and pump wear.

Disassembly

When disassembling the pump, lay out all removed parts in sequence, to ease reassembly.

NOTE: Repair Kit 222773 is available for Displacement Pumps 222790, 237206, 237450 and 246933. The kit includes piston and intake seals and cylinder o-rings. For the best results, use all the new parts in the kit. Kit parts are marked with one asterisk, for example (11*).

Repair Kits 222774 (UHMWPE/PTFE), 222775 (PTFE), 237916 (UHMWPE/leather), and 234422 (UHMWPE/Tuffstack) are available to replace the throat packings. For the best results, use all the new parts in the kit. Kit parts are marked with a symbol, for example (3{). See page 32.

Repair Kit 222793 is available to service the intake valve of Displacement Pumps 222790, 237206, 237450 and 246933. For the best results, use all the new parts in the kit. Kit parts are marked with a symbol, for example (19}).

1. Remove the displacement pump from the air motor as explained on page 14. Place the pump in a vise, with the jaws on the outlet housing (10).

2. Hold the flats of the priming piston rod (24) with a 12 mm wrench. Using a 22 mm wrench, unscrew the priming piston nut (30). Slide the priming piston (25) and piston guide (31) off the rod. Inspect the surfaces of the guide (31) and piston (25) for scoring, wear, or other damage.

3. Loosen the packing nut (2) using the wrench (110) supplied, or a hammer and brass rod. Remove the intake cylinder (23), using an adjustable wrench.

4. Unscrew the intake valve housing (17) from the cylinder (12), using an adjustable wrench. Pull the housing off the pump. The intake check valve assembly (DD) should slide down the priming piston rod (24) as you remove the housing; if it does not slide easily, firmly tap on the top of the housing (17) with a rubber mallet to loosen.

5. Use an o-ring pick to remove the seal (21) from the intake valve housing (17). Discard the seal; use a new one for reassembly. Pull the intake valve seat (22) out the bottom of the housing (17). If the seat is difficult to remove, insert a brass rod through the top of the housing and drive the seat out with a hammer. Take care not to drop the check valve assembly (DD) as it comes free, and set it aside for later.

6. Push the displacement rod (1) down as far as possible, then pull it and the priming piston rod (24) out of the outlet housing (10) and cylinder (12).

7. Remove the packing nut (2), throat packings (5 and/or 3) and glands (4 and 6) from the outlet housing (10). Some models include a fluid outlet nipple (8) and o-ring (9). Do not remove these parts from the housing unless they need replacement.

8. Unscrew the bleeder valve plug (35) completely from the valve body (43). Clean the valve threads and the bleed hole. It is not necessary to remove the valve body from the pump outlet housing (10).

9. Use a 400 mm adjustable wrench on the flats of the pump cylinder (12) and unscrew the cylinder from the outlet housing (10). Remove the o-rings (11). Inspect the inside surface of the cylinder for wear, scoring or other damage by holding it up to the light at an angle or running a finger over the surface.

10. Inspect the outer surfaces of the displacement rod (1) and priming piston rod (24) for wear, scoring or other damage by holding them up to the light at an angle or running a finger over the surface.

11. Use a vise with soft jaws to hold the displacement rod (1) by its flats. Place a 19 mm wrench on the flats of the piston and unscrew the piston (13) and priming piston rod (24) from the displacement rod (1). Remove the spacer (33). Disassemble the piston guide (14) from the piston (13).

12. It is not necessary to remove the priming piston rod (24) from the piston (13) unless your inspection reveals scoring, wear, or other damage to either part. To disassemble, place the piston flats in a vise and unscrew the rod, using a 12 mm wrench on the flats.

13. Place the flats of the piston seat (16) in a vise. Using a 13 mm (1/2 in.) dia. brass rod (EE), unscrew the piston guide (14) from the piston seat (16). See Fig. 6. Remove the piston seal (15); always replace with a new one. Inspect the mating surfaces of the piston (13) and piston seat (16) for nicks, scoring or wear.

14. To disassemble the intake check valve (DD), place the nut (18) in a vise and unscrew the intake valve body (19), using a 28 mm wrench. See Fig. 7. Remove the seals (42, 20) from the nut and from the valve body; always replace them with new ones. Inspect the mating surfaces of the intake valve body (19) and seat (22) for wear, scoring, or other damage.

NOTE: The seal (42) is press-fit in the nut (18) and may require cutting to ease removal.

15. Inspect all parts for damage and clean with a compatible solvent. To reassemble, refer to page

Reassembly (Refer to Fig. 8)

1. Place a 13 mm (1/2 in.) diameter brass rod lengthwise in a vise. Install a new piston seal (15*) on the piston seat. Apply thread sealant to the threads of the piston seat. Place the piston guide (14) securely on the brass rod. Using a 32 mm crow’s-foot, screw the piston seat (16) into the piston guide. Torque to 27–34 N.m (20–25 ft-lb).

2. If it was necessary to remove the priming piston rod (24) from the piston (13), apply thread sealant to the threads of the rod. Place the flats of the piston (13) in a vise. Hold the flats of the rod with a 12 mm wrench, and screw the rod into the piston. Torque to 45–53 N.m (33–39 ft-lb).

3. Use a vise with soft jaws to hold the displacement rod (1) by its flats. Install the spacer (33, see the following note) on the rod. Install the assembled piston guide/seat on the piston (13). Apply thread sealant to the threads of the displacement rod, and screw the piston assembly onto the rod, using a 19 mm wrench on the flats of the piston. Torque to 120–130 N.m (88–95 ft-lb). There will be a small gap between the top of the piston (13) and the shoulder of the rod (1).

NOTE: The piston spacer (33) is not required when pumping fluids with a viscosity greater than 1 million centipoise.

4. Lubricate the threads of the bleeder valve plug (35). The plug has two sets of threads. Be sure to screw the plug completely into the valve body (43). Torque the plug to 30–38

NOTE: Some models include an outlet nipple (8) and o-ring (9*). It is not ordinarily necessary to remove these parts. However, if they were replaced because of damage, lubricate the o-ring and place it on the nipple. Screw the nipple into the outlet housing (10). Torque to 70–75 N.m (51–55 ft-lb).

5. Lubricate the o-rings (11*) and install them on the cylinder (12). Apply thread lubricant to the top threads of the cylinder. Using a 400 mm wrench on the flats of the cylinder, screw it into the outlet housing (10). Torque to 325–354 N.m (240–260 ft-lb).

6. Lubricate the throat packings and glands, and install them in the outlet housing (10) one at a time in the following order, with the lips of the v-pack- ings facing down: the male gland (6{), v-pack- ings (see the NOTE below), and the female gland (4{). Apply thread lubricant to the packing nut (2) and install the nut loosely in the outlet housing.

NOTE: Refer to page 32 for the correct throat packing configuration for your pump.

7. Carefully insert the displacement rod (1) into the bottom of the cylinder (12). Push the rod up into the cylinder and through the outlet housing (10), until it protrudes from the packing nut (2). Be careful not to damage the piston seal (15*) while performing this step.

8. Apply thread lubricant to the bottom threads of the cylinder (12). Be sure the o-ring (11*) is in place on the cylinder. Guide the intake valve housing (17) up onto the priming piston rod (24) and screw it onto the cylinder, using an adjustable wrench. Torque to 325–354 N.m (240–260 ft-lb).

12. Place a 26 mm wrench on the flats of the packing nut (18) and a 28 mm wrench on the flats of the valve body (19). Screw the nut into the body, making certain they remain in position above the flats of the rod (24). Torque to 45–53 N.m (33–39 ft-lb). Slide the assembled intake check valve up the priming piston rod until it reaches the stop (FF); this may be difficult due to high friction between the seal and rod.

13. Position the intake valve seat (22) so its large beveled side faces down toward the pump intake. Slide the seat (22) onto the priming piston rod (24) and into the intake valve housing (17) until it seats on the lower lip of the housing.

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 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.
