CAUTION: Before attempting any maintenance or repair, disconnect the compressed
air line to the pump and allow all air pressure to bleed from the pump. Disconnect all
intake, discharge, and air lines. Drain the pump by turning it upside down and allowing
any fluid to flow into a suitable container. Be aware of any hazardous effects of contact
with your process fluid.
NOTE: Your specific pump model may vary from the configuration shown; however,
pump disassembly procedure will be the same.
NOTE: Replace worn parts with genuine Wilden parts for reliable performance.
