CAUTION:
Before any maintenance or repair is attempt- ed, 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 any hazardous effects of contact with your process fluid.
The Wilden model P2 has a 25 mm
(1”) inlet and 25 mm (1”) outlet and is
designed for flows up to 140 lpm (37 gpm). The wetted path comes in both
PVDF and polypropylene. The single-piece center section, consisting of center
block and air chambers, is molded of polypropylene or acetal. The air valve
body is manufactured of acetal or polypropylene. All o-rings used in the pump
are of a special material and shore hardness that should only be replaced with
factory-supplied parts.
PLEASE read all directions before starting disassembly.
NOTE:
The model used for these instructions incorporates rubber diaphragms,
balls, and seats. Models with PTFE diaphragms, balls and seats are the same
except where noted.
NOTE:
Replace worn parts with genuine Wilden parts for reliable performance.
Step 1
Before starting disassembly, mark a line from each liquid
chamber to its corresponding air chamber. This line will
assist in proper alignment during reassembly.

Using a screwdriver or other long, slim object, loosen the
top liquid retainers from the liquid chambers.
