Symbols Warning Symbol Caution Symbol WARNING CAUTION This symbol alerts you to the possibility of serious injury or death if you do not follow the instructions. This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions. WARNING EQUIPMENT MISUSE HAZARD Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury. INSTRUCTIONS D This equipment is for professional use only.
WARNING TOXIC FLUID HAZARD Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. D Know the specific hazards of the fluid you are using. D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines. D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer.
Installation General Information D The Typical Installation shown in Fig. 2 is only a guide for selecting and installing system components. Contact your Graco distributor or Graco Technical Assistance (see back page) for assistance in planning a system to suit your needs. D Always use Genuine Graco Parts and Accessories. Be sure all accessories are adequately sized and pressure-rated to meet the system’s requirements.
Installation Ground all of this equipment: Grounding WARNING FIRE AND EXPLOSION HAZARD This pump must be grounded. Before operating the pump, ground the system as explained below. Also, read the section FIRE AND EXPLOSION HAZARD, on page 4. Polypropylene and PVDF are not conductive. Attaching the ground wire to the grounding lug will ground only the air motor.
Installation b. Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. See the WARNING at left. Locate the other master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair. Air Line WARNING A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump.
Installation Installation of Remote Pilot Air Lines Fluid Suction Line 1. Refer to Parts Drawings. Connect air line to pump as in preceding steps. 1. The pump fluid inlet (R) is a 2” raised face flange. Refer to Flange Connections on page 9. 2. Connect 1/4 in. O.D. tubing to push type connectors (14) on air motor of pump. 2. If the fluid inlet pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation.
Installation 1. Place a flat washer (E) on each bolt (C). Refer to Fig. 3. Flange Connections The fluid inlet and outlet ports are 2” raised face, standard 150 lb class pipe flanges. Connect 2” flanged plastic pipe to the pump as follows. You will need: 2. Align the holes in the gasket (B) and the pipe flange (A) with the holes in the pump outlet flange (S). D Torque wrench D Adjustable wrench 3. Lubricate the threads of the four bolts.
Installation Changing the Orientation of the Fluid Inlet and Outlet Ports The pump is shipped with the fluid inlet (R) and outlet (S) ports facing the same direction. See Fig. 4. To change the orientation of the inlet and/or outlet port: 1. Remove the screws and washers (106, 112, 113 and 114) holding the inlet (102) and/or outlet (103) manifold to the covers (101). 2. Reverse the manifold and reattach. Install the screws and washers and torque to 150–160 in–lb (17–18 NSm). See Torque Sequence, page 32.
Installation The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation. Air Exhaust Ventilation WARNING If the muffler (P) is installed directly to the air exhaust port, apply PTFE thread tape or anti–seize thread lubricant to the muffler threads before assembly.
Operation Pressure Relief Procedure 1. Be sure the pump is properly grounded. Refer to Grounding on page 6. WARNING PRESSURIZED EQUIPMENT HAZARD The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun or splashing fluid, follow this procedure whenever you: D D D D Are instructed to relieve pressure, Stop pumping, Check, clean or service any system equipment, Install or clean fluid nozzles. 1.
Operation Operation of Remote Piloted Pumps 1. Fig. 2 and Parts Drawings. Follow preceding steps 1 through 7 of Starting and Adjusting Pump. 2. Open air regulator (C). NOTE: Leaving air pressure applied to the air motor for extended periods when the pump is not running may shorten the diaphragm life. Using a 3–way solenoid valve to automatically relieve the pressure on the air motor when the metering cycle is complete prevents this from occurring.
Troubleshooting 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 before checking or servicing the equipment. 2. Check all possible problems and causes before disassembling the pump. PROBLEM CAUSE SOLUTION Pump cycles at stall or fails to hold pressure at stall. Worn check valve balls (301), seats (201) or o-rings (202). Replace. See page 18.
Troubleshooting PROBLEM CAUSE SOLUTION Fluid in exhaust air. Diaphragm ruptured. Replace. See pages 19–22. Loose fluid side diaphragm plate (105). Tighten or replace. See pages 19–22. Worn air valve block (7), o-ring (6), plate (8), pilot block (18), u-cups (10), or pilot pin o-rings (17). Inspect; replace. See pages 16–17. Worn shaft seals (402). Replace. See pages 19–22. Pump exhausts excessive air at stall. Pump leaks air externally. Air valve cover (2) or air valve cover Tighten screws.

Service 4. Unscrew one outer plate (105) from the diaphragm shaft (24). Remove one diaphragm (401), and the inner plate (104). See Fig. 13. For overmolded diaphragms: Grip both diaphragms securely around the outer edge and rotate counterclockwise. One diaphragm assembly will come free and the other will remain attached to the shaft. Remove the freed diaphragm and air side plate. NOTE: PTFE models include a PTFE diaphragm (403) in addition to the backup diaphragm (401). 5.
Reassembly – Overmolded Diaphragms WARNING To reduce the risk of serious injury, including amputation, do not put your fingers or hand between the air cover and the diaphragm. 1. Lubricate and install the shaft u–cup packings (402*) so the lips face out of the housing (1). See Fig. 13. 2. Assemble the air side plate (104) onto the diaphragm (403). The wide, radiused side of the plate must face the diaphragm. Apply medium–strength (blue) Loctite or equivalent to the threads of the diaphragm assembly.
