Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. When these symbols appear in the body of this manual, refer back to these Warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
Warnings WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • • • • • • • • • • • • • Do not operate the unit when fatigued or under the influence of drugs or alcohol. Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Warnings WARNING TOXIC FLUID OR FUMES HAZARD Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed. • • • Read MSDSs to know the specific hazards of the fluids you are using. Route exhaust away from work area. If diaphragm ruptures, fluid may be exhausted into the air. Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
Troubleshooting Troubleshooting Problem Pump cycles but will not prime. Cause Solution Pump is running too fast, causing cavitation before prime. Reduce air inlet pressure. Check valve ball severely worn or wedged in seat or manifold. Replace ball and seat. See page 12. Seat severely worn. Replace ball and seat. See page 12. Outlet or inlet clogged. Unclog. Inlet or outlet valve closed. Open. Inlet fittings or manifolds loose. Tighten. Manifold o-rings damaged. Replace o-rings.
Troubleshooting Problem Exhaust air contains fluid being pumped. Moisture in exhaust air. Cause Diaphragm (or backup) ruptured. Replace. See page 14. Loose diaphragm shaft bolt. Tighten or replace. See page 14. Diaphragm shaft bolt o-ring damaged. Replace o-ring. See page 14. High inlet air humidity. Use drier air supply. Pump exhausts excessive air at stall. Worn air valve cup or plate. Pump leaks air externally. Pump leaks fluid externally from joints.
Repair Repair Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until pressure is relieved manually. To help prevent serious injury from pressurized fluid, such as splashing in the eyes or on skin, follow the Pressure Relief Procedure whenever you stop pumping and before you clean, check, or service the equipment. 1. Shut off the air supply to the pump. 2. Open the dispensing valve, if used. 3.
Repair Reassemble the Air Valve NOTE: Apply lithium-based grease whenever instructed to grease. Order Graco PN 111920. 1. Use all parts in the repair kits. Clean other parts and inspect for damage. Replace as needed. 2. Grease the detent cam (204◆) and install into housing (201). 3. Grease the u-cups (208◆†) and install on the piston with lips facing toward the center of the piston. 4. Grease both ends of the piston (202◆) and the housing bore.
Repair 7. Grease and install the detent assembly (203◆) into the piston. Install the o-ring (214◆) on the cup (213◆). Apply a light film of grease to the outside surface of the o-ring and the inside mating surface of the base (212◆). Orient the end of the base that has a magnet toward the end of the cup that has the larger cutout. Engage the opposite end of the parts. Leave the end with the magnet free. Tilt the base toward the cup and fully engage the parts, using care so that the o-ring remains in place.

Repair Diaphragms and Center Section b. Plastic Pumps: Hold the hex of one fluid side diaphragm plate (15) with a 1-5/8 socket or box end wrench. Use another wrench (same size) on the hex of the other plate to remove. Then remove all parts of the diaphragm assembly. See FIG. 7. Metal Pumps: Turn the pump on its side. Hold one diaphragm shaft bolt (16) with a wrench, then use a 15/16 socket to remove the other bolt. Remove all parts of the diaphragm assembly. See FIG. 7, page 17. c.
Repair Reassembly of Housing Parts and Air Covers Follow all notes in FIG. 7. These notes contain important information. NOTE: Apply lithium-based grease whenever instructed to grease. Order Graco PN 111920. 4. Assemble air covers, if removed: a. Put one air cover on the bench. Install the alignment pins (112*) and a new gasket (107*). b. Carefully place the center section on the air cover. c. Install second set of alignment pins (112*) and gasket (107*) in the center section.
Repair Reassembly of Standard Diaphragms NOTE: If your pump has overmolded diaphragms, see page 19. PTFE Diaphragms 1. Clean all parts and inspect for wear or damage. Replace parts as needed. 2. Clamp the shaft flats in a vise. 3. For metal pumps, install the washer (18) and o-ring (17) on the shaft bolt (16). 4. Assemble the fluid side plate (15), the diaphragm (20), the backup diaphragm (305), the air side diaphragm plate (14), and the washer (18) on the bolt exactly as shown in FIG. 7. 5.

Repair All Other Standard Diaphragms - Metal Pumps: 1. Install the washer (18) and o-ring (17) on the shaft bolt (16). 2. Assemble the fluid side plate (15), the diaphragm (20), the air side diaphragm plate (14), and the washer (18) on the bolt exactly as shown in FIG. 7. 3. Apply medium-strength (blue) Loctite or equivalent to the bolt (16) threads. Screw the bolt into the shaft hand tight. 4. Grease the shaft u-cups (101*) and the length and ends of the diaphragm shaft (108*).
Repair Attach Second Fluid Cover To reduce the risk of serious injury, do not put your fingers or hand between the air cover and the diaphragm. NOTE: If you are replacing the diaphragms but not the air valve, you still must remove the air valve, and replace the gasket with the tool so the air valve can be used for proper installation of the second fluid cover. Remember to remove the tool and replace the gasket when finished.
Repair Torque Instructions See FIG. 9 for fluid cover and air valve fasteners. See FIG. 10 for manifold fasteners. NOTE: Fluid cover and manifold fasteners on the polypropylene pumps have a thread-locking adhesive patch applied to the threads. If this patch is excessively worn, the fasteners may loosen during operation. Replace screws with new ones or apply medium-strength (blue) Loctite or equivalent to the threads.
