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 VA25A-A01AA1SSBNBNPT represents a 1 inch, 50 gpm aluminum pump (VA25A), with aluminum center section (A01), a standard air valve (A), aluminum fluid covers (A) and manifolds with standard ports in inches (1).

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 2. Check fittings to be sure they are tight. Use unexpectedly, which could result in serious a compatible liquid thread sealant on male injury from splashing.

Flush before fluid can dry in the equipment, • 11. Close the bleed-type master air valve. at the end of the day, before storing, and before repairing equipment.
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.

Operating Temperature Range NOTICE Temperature limits are based on mechanical stress only. Certain chemicals will further limit the fluid temperature range. Stay within the temperature range of the most-restricted wetted compo- nent. Operating at a fluid temperature that is too high or too low for the components of your pump may cause equipment damage.
