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. Discon-
nect 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 T4 has a 38 mm (1-1/2") inlet and 32 mm (1-1/4")
outlet and is designed for flows up to 81 gpm (307 lpm). The
model T4 is available in aluminum, cast iron, or 316 stainless
steel wetted parts. The air valve is manufactured of brass,
PTFE-coated brass, nickel-plated brass or stainless steel.
All o-rings used in the pump are of a special material and
shore hardness which should only be replaced with factory-
supplied parts.
TOOLS REQUIRED:
Adjustable Wrench
1/2" Wrench
3/8" Box Wrench
3/16" Allen Wrench
Vise equipped with soft jaws (such as plywood, plastic
or other suitable material)
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. The procedures for A4 Accu-Flo™ pumps are the
same except for the air distribution system.
DISASSEMBLY:
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.
