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 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.
The Wilden single-piece manifold pump models are air- operated, double-diaphragm
pumps with all wetted parts molded in PTFE PFA
.
The single-piece center section,
consisting of center block and air chambers, is molded from glass-filled acetal on
conductive models. All fasteners and hardware are stainless steel. The primary
diaphragm is constructed of PTFE. All wetted sealing o-rings are PTFE encapsulated
FKM on the UPII. The standard air distribution system is used on the UPII. All o-rings
used in the pump are of a special material, and should only be replaced with Wilden
factory-supplied parts.
NOTE:
Replace worn parts with genuine Wilden parts for reliable performance.
PLEASE read all directions before starting disassembly.
DISASSEMBLY:
Before actual disassembly is started, turn pump upside down
and drain all liquid trapped in the pump into a suitable container.
Be sure to use proper caution if liquid is corrosive or toxic.
Mark each liquid chamber to its respective air chamber for easy
alignment during reassembly.
