Disassembly / Reassembly
Air Valve / Center Section Disassembly
Tools Required:
• 5/32" Hex Head
Wrench
• O-ring Pick
CAUTION: Before any maintenance or repair is attempted, the compressed air line to the pump
should be disconnected and all air pressure allowed 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 hazardous effects of contact with your process fluid.
The P.025 plastic utilizes a revolutionary Pro-Flo
®
air distribution system. A 3 mm (1/8”) air inlet
connects the air supply to the center section. Proprietary composite seals reduce the coefficient of
friction and allow the P.025 to run lube-free. Constructed of Acetal or polypropylene, the Pro-Flo air
distribution system is designed to perform in on/off, non-freezing, non-stalling, tough duty applications.
NOTE: Replace worn parts with genuine Wilden parts for reliable performance.
