DIRECTIONS FOR DISASSEMBLY/REASSEMBLY
Step 2.
Figure 2
Utilizing the 13 mm (1/2") box wrench, remove the two small
clamp bands that fasten the discharge manifold to the liquid
chambers.
Step 3.
Figure 3
Remove the discharge manifold to expose the valve balls and
seats. Inspect the ball cage area of the manifold for excessive
wear or damage. Remove the discharge valve balls, seats and
o-rings from the discharge manifold and inspect for nicks,
gouges, chemical attack or abrasive wear. Replace worn parts
with genuine Wilden parts for reliable performance. PTFE
o-rings should be replaced when reassembled.
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 T8 has a 51 mm (2") inlet and 51 mm (2") outlet
and is designed for flows up to 617 lpm (163 gpm). The model
T8 is available in aluminum, cast iron, or 316 stainless steel
wetted parts. The center block is available in polypropylene,
aluminum, nickel-plated aluminum, PTFE-coated aluminum
and 316 stainless steel. All o-rings used in the pump are of
a special material and shore hardness that should only be
replaced with factory-supplied parts.
TOOLS REQUIRED:
Adjustable Wrench
13 mm (1/2") Socket
14 mm (9/16") Box Wrench
17 mm (11/16") Socket
25 mm (1") Box Wrench or Adjustable 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 A8 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.
