Pump Models ETL LISTED PUMPS NON-LISTED PUMPS The following pumps are ETL listed for light viscosity paints, lacquers, varnishes, thinners, solvents when installed in accordance with NFPA (National Fire Protection Association) Standards No. 30, Flammable and Combustible Liquids Code, and No. 33 Spray Finishing Using Flammable Materials. The ETL listed pumps have been evaluated using ASTM Reference Fuels A, C, H, I, and IRM No.
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 for assistance in planning a system to suit your needs. D Always use Genuine Graco Parts and Accessories. D Reference numbers and letters in parentheses refer to the callouts in the figures and the parts lists on pages 12–34. 2. Non ETL–Listed Pumps: See Fig. 1. Remove the ground screw (Z).

Installation System Accessories Model 226951 Only Refer to Fig. 2 and the Accessories section. Using moderate force, extend the pump suction tube, insert the pump into the drum or tank bung hole, and screw the bung adapter (B) tightly into the bung hole. Lift the pump about 13 mm (0.5 in.) and tighten the bung adapter (B) screw to hold the pump. Loosen the vent plug (A). Refer to Fig. 2.
Operation Pressure Relief Procedure WARNING PRESSURIZED EQUIPMENT HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: D D D D are instructed to relieve the pressure, stop spraying, check or service any of the system equipment, or install or clean the spray nozzle.
Maintenance Fill the wet-cup (P) 1/2 full of Graco Throat Seal Liquid (TSL) or compatible solvent and keep it 1/2 full to keep fluid from drying on the displacement rod and damaging pump throat packings. See Fig. 5. Lubricate the throat packings frequently when you are pumping a non-lubricating fluid, or are shutting down for more than a few days. Some pumps have a grease fitting (DD) for this purpose. See Fig. 5. WARNING Do not attempt to adjust the packing nut with the pump operating.
Troubleshooting WARNING 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. Check all other possible remedies before disassembling the pump. PROBLEM CAUSE SOLUTION The pump fails to operate. Dirty or worn air motor. Clean, service; see the separate motor manual 307456. Inadequate air supply or restricted Clean lines or increase the air supply lines. (see Technical Data).
Pump Service Disconnecting the Air Motor WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. 115 103 3 1. Flush the pump. 2. Relieve the pressure. Remove the pump from its mounting. S 3. See Fig. 6. Unscrew the tie rod locknuts (103). 4. Unscrew and remove the screw (105) and barrel (104). 105 104 5. Raise the air motor (115) away from the displacement pump (114).
