System Accessories
WARNING
A bleed-type master air valve (B) and a fluid drain valve (J) are required in your system. These acces­sories help reduce the risk of serious injury includ­ing skin 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 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. 113269.
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. Order Part No. 210657.
Air and Fluid Hoses
Be sure all air and fluid hoses are properly sized and pressure-rated for your system. Use only electrically conductive air and fluid hoses. Use a 1/2 in. (13 mm) I.D. (minimum) air hose (A) to supply air to the pump.
Connect a fluid hose (P) to the pump’s 1/2 npt(f) fluid outlet. Connect a fluid suction hose and tube (S) to the pump’s 3/4 npt(m) fluid intake.
Air Line Accessories
Install the following accessories in the order shown in Fig. 2, using adapters as necessary:
D A bleed-type master air valve (B) is required in
your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING above). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air regulator (C).
D An air line filter (F) removes harmful dirt and
moisture from the compressed air supply. Also, install a moisture trap and drain valve (H) to help remove moisture and contaminants from the com­pressed air supply. Install these accessories on the pump air supply line and the air supply line to an air-assisted airless spray gun.
D A second bleed-type air valve (G) isolates the air
line accessories for servicing. Locate upstream from all other air line accessories.
D A gun air regulator (T) adjusts the air pressure to
the air-assisted airless spray gun (R).
Fluid Line Accessories
Install the following accessories in the positions shown in Fig. 2, using adapters as necessary:
D A fluid drain valve (J) is required in your system
to relieve fluid pressure in the hose and gun (see the WARNING at left). Install the drain valve point­ing down, but so the handle points up when opened.
D A fluid filter (K) filters harmful particles from the
fluid.
D A fluid shutoff valve (L) shuts off the fluid flow to
the gun.
D An air regulator (C) 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 bleed-type master air valve (B).
D An air line lubricator (D) provides automatic air
motor lubrication.
D A pump runaway valve (E) shuts off the pump if it
starts running too fast. A pump which runs too fast can seriously damage itself.

Pressure Relief Procedure
Operation
WARNING
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually relieved to prevent the system from
starting or spraying 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,
D check or service any of the system equipment,
D or install or clean the spray tip.
1. Lock the gun trigger safety.
2. Close the bleed-type master air valve (B, required in your system).
3. Unlock the gun trigger safety.
4. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.
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 the pressure. Using a spanner wrench or 1/4 in. (6 mm) diameter rod, tighten the nut just enough to stop the leakage. Do this when­ever necessary. Do not overtighten the packing nut.
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. If the pump is being used to supply a circulating system, allow the solvent to circulate until the pump is thoroughly flushed. See Flushing on page 11.
5. Lock the gun trigger safety.
6. Open the drain valve (J, required in your system), having a container ready to catch the drainage.
7. Leave the drain valve open until you are ready to spray again.
If you suspect that the spray tip 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 or hose.
Packing Nut/Wet-Cup
Before starting, fill the packing nut (W) 1/2 full with Graco Throat Seal Liquid (TSL) or compatible solvent. See Fig. 3.

Operation
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your fingers or other body parts. When air is supplied to the motor, the air motor
piston (located behind the air motor plates) moves. Therefore, never operate the pump with the air motor plates (P) removed. See Fig. 3.
Starting and Adjusting the Pump
Begin these steps before you install the spray tip.
1. Ensure that the air regulator (C) and bleed-type master air valve (B) are closed. See Fig. 2 on page 7.
2. Connect a suction hose (S) to the pump’s fluid inlet.
10. Control the pump speed and fluid pressure with the air regulator (C). Always use the lowest air pressure necessary to get the desired results. Higher pressure causes premature spray tip and pump wear.
NOTE: For more precise control of fluid pressure at the gun, use a fluid pressure regulator (M).
11. With the pump and lines primed, and with ade­quate air pressure and volume supplied, the pump starts and stops as the spray gun is opened and closed. In a circulating system, the pump runs continuously and speeds up or slows down as supply increases or decreases until the air supply is shut off.
CAUTION
3. Hold a metal part of the spray gun (R) firmly to the side of a grounded metal pail and hold the trigger open.
4. Open the pump’s bleed-type master air valve (B).
5. Slowly open the air regulator (C) until the pump starts (approximately 40 psi [0.28 MPa, 2.8 bar]).
6. Cycle the pump slowly until all the air is pushed out and the pump and hoses are fully primed.
7. Release the spray gun trigger and lock the trigger safety. The pump should stall against pressure when you release the trigger.
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.
8. Relieve the pressure.
9. Install the spray tip in the gun.
WARNING
Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. If your pump accel­erates quickly, or is running too fast, stop it immedi­ately and check the fluid supply. If the supply con­tainer is empty and air has been pumped into the lines, refill the container and prime the pump and the lines with fluid, or flush and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid system.
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
page 22).

Shutdown and Care of the Pump
Operation
WARNING
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.
For overnight shutdown, relieve the pressure. Always stop the pump at the bottom of the stroke to prevent the fluid from drying on the exposed displacement rod and damaging the throat packings.
Always flush the pump before the fluid dries on the displacement rod. Never leave water or water-base fluid in the pump overnight. First, flush with water or a compatible solvent, then with mineral spirits. Relieve the pressure, but leave the mineral spirits in the pump to protect the parts from corrosion.
Flushing
WARNING
FIRE AND EXPLOSION HAZARD Before flushing, read the section FIRE AND EXPLOSION HAZARD on page
4. Be sure the entire system and flush­ing pails are properly grounded. Refer to Grounding on page 5.
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.
1. Relieve the pressure.
2. Remove the tip guard and spray tip from the gun. See the gun instruction manual.
3. Remove the filter element from the fluid filter (K). Reinstall the filter bowl.
4. Place the suction tube (S) in a container of solvent.
5. Hold a metal part of the gun firmly to the side of a grounded metal pail.
Flush the pump:
D Before the first use
D When changing colors or fluids
D Before fluid can dry or settle out in a dormant pump
(check the pot life of catalyzed fluids)
D Before storing the pump.
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.
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.
6. Start the pump. Always use the lowest possible fluid pressure when flushing.
7. Trigger the gun.
8. Flush the system until clear solvent flows from the gun.
9. Relieve the pressure.
10. Clean the tip guard, spray tip, and fluid filter ele­ment separately, then reinstall them.
11. Clean the inside and outside of the suction tube (S).

Displacement Pump Service (215930 only)
Disassembly
When disassembling the pump, lay out all removed parts in sequence, to ease reassembly. Refer to Fig. 6.
NOTE: Repair Kit 218559 is available. For the best results, use all the new parts in the kit. Parts included in the kit are marked with one asterisk.
Always replace the glands when replacing the pack­ings, whether or not you use a repair kit. Install the packings one at a time to be sure they “nest” properly.
Clean all the parts thoroughly when disassembling. Check them carefully for damage or wear, replacing parts as needed.
1. Unscrew intake valve housing (6) from pump housing (3). Remove pin (11), ball (9), retainer (12), and o–ring (10). See Fig. 6. If seat in valve housing (6) is chipped or worn, replace housing.
2. Loosen throat packing nut (4). Push displacement rod (19) down until the piston body clears the bottom of the pump housing (3). Grasp piston (5), and pull piston and displacement rod out through bottom of pump housing, being careful not to scratch the sleeve inside the housing.
3. Screw the piston body (5) out of the rod (19). Remove the ball (8), glands (31 and 32), packings (14), shims (29) and packing retainer (21).
Assembly
1. Lubricate packings, displacement rod (19) and inside of sleeve (18) before assembling.
2. Install male gland (31*), five v–packings (14*) with the lips facing down, and female gland (32*) in throat of pump housing (3). See Detail A of Fig. 6. Install packing nut (4) loosely.
NOTE: If the ball stop pin (20) and ball guide (36) were removed from the displacement rod during disassem­bly, reinstall them and secure with the cotter pins (7). Make sure the ball stop pin is in the top set of holes.
3. Install the piston ball (8*) on the piston and screw the piston valve assembly into the displacement rod (19) Torque to 35–40 ft–lb (47–54 NSm).
4. Install up to six shims (29*) on the piston, to attain a packing stack height of 0.668–0.683 in. (17.0–17.3 mm). Install the female gland (32*), five v–packings (14*) with the lips facing up, male gland (31*), and packing retainer (21) on the piston (5). Verify that the packing stack height is correct. See Detail B of Fig. 6.
NOTE: Inspect the ball stop pin (20) and ball guide (36) in place. If either is damaged, or if the displace­ment rod is being replaced, remove one cotter pin (7) and pull the ball stop pin out of the rod (19). Remove the ball guide.
4. Screw throat packing nut (4) out of pump housing (3). Remove packings (14) and glands (31 and
32).
5. Clean all parts and threads with a compatible solvent and blow dry before reassembling. Inspect all parts for wear or damage. Inspect the polished surfaces of the displacement rod (19) and sleeve (18) for scratches, scoring or other damage, which can cause premature packing wear and leaking. To check, run a finger over the surface or hold the part up to the light at an angle. If one of these parts is worn or damaged, replace both parts. When replacing the sleeve, be sure to replace the gasket (17*).
NOTE: If the sleeve (18) needs replacement and is hard to remove, contact your Graco distributor.
306936
16
NOTE: If you removed the sleeve (18), reinstall it in
the outlet housing (3), making sure to replace the gasket (17*). Be sure the tapered end of the sleeve
faces down, toward the pump intake.
5. Place ball (8*) on piston (5). Apply liquid thread sealant to threads of piston (5) and screw piston into displacement rod (19). Torque to 35–40 ft–lb (47–54 NSm). Install displacement rod (19) and piston (5) up through bottom of pump housing (3).
6. Place ball (9*) in intake housing (6) and install o–ring (10), retainer (12), and pin (11) in housing. Lubricate threads of valve housing (6) and screw valve housing into pump housing (3). Tighten throat packing nut (4) just enough to stop leakage – no tighter.
7. Reconnect the displacement pump to the air motor as explained on page 13.
