Pump Matrix Pump Matrix Check the identification plate (ID) for the 20-digit part number of your pump. Use the following matrix to define the components of your pump. For example, pump number 1050A-A01AA1SSBNBNPT represents a Husky 1 inch, 50 gpm aluminum pump (1050A), with aluminum center section (A01), a standard air valve (A), aluminum fluid covers (A) and manifolds with standard ports in inches (1).
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. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable. WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode.
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.
Installation 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 MSDS’s to know the specific hazards of the fluids you are using. • Route exhaust away from work area. If diaphragm ruptures, fluid may be exhausted with air. • Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines. • Always wear impervious gloves when spraying or cleaning equipment.
Installation Mounting • • The pump exhaust air may contain contaminants. Ventilate to a remote area. See Air Exhaust Ventilation on page 8. Never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure on page 14 before moving or lifting the pump. wire to a true earth ground. A ground wire and clamp, Part 238909, is available from Graco. Polypropylene: Only conductive polypropylene pumps have a ground screw.
Installation Check your system electrical continuity after the initial installation, and then set up a regular schedule for checking continuity to be sure proper grounding is maintained. Remote option: Insert 5/32 OD tubing into the push-to-connect fitting at each pilot and route to your control. NOTICE Air Line See FIG. 3 and FIG. 4, pages 10 and 11. 1. Install an air regulator (C) and gauge to control the fluid pressure. The fluid stall pressure will be the same as the setting of the air regulator. 2.

Installation Fluid Inlet and Outlet Ports NOTE: Remove and reverse the manifold(s) to change the orientation of inlet or outlet port(s). Follow Torque Instructions on page 16. Aluminum (1050A) The fluid inlet and outlet manifolds each have four 1 in. npt(f) or bspt threaded ports (FIG. 3, M, N). Close off the unused ports, using the supplied plugs. Plastic (1050P, 1050C) The fluid inlet and outlet manifolds each have a 1 in. raised face ANSI/DIN flange (FIG. 4, M, N) in either a center or end location.
Installation Fluid Pressure Relief Valve Some systems may require installation of a pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose. Thermal expansion of fluid in the outlet line can cause overpressurization. Thermal expansion can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm area (for example, from an underground tank).
Operation Operation Pressure Relief Procedure Starting and Adjusting the Pump 1. Be sure the pump is properly grounded. Refer to Grounding on page 7. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing. 1. Shut off the air supply to the pump. 2. Open the dispensing valve, if used. 3. Open the fluid drain valve to relieve fluid pressure. Have a container ready to catch the drainage. Flush the Pump Before First Use The pump was tested in water.
Maintenance 10. If you are flushing, run the pump long enough to thoroughly clean the pump and hoses. 11. Close the dispensing valve, if used. 12. Close the bleed-type master air valve. 13. Pumps with runaway protection: Disable the prime/flush function by pushing the prime/flush button on the DataTrak. DataTrak Operation Tighten Threaded Connections Before each use, check all hoses for wear or damage and replace as necessary. Check to be sure all threaded connections are tight and leak-free.
Maintenance Torque Instructions NOTE: Fluid cover and manifold fasteners 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. If fluid cover or manifold fasteners have been loosened, it is important to torque them using the following procedure to improve sealing.
