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 any hazardous effects of contact with your process fluid.
The Wilden T15 has a 76 mm (3") inlet and 76 mm (3") outlet and is designed
for flows up to 878 lpm (232 gpm). The T15 is available in aluminum, cast iron
or 316 stainless steel wetted parts. The center block is available in
polypropylene, aluminum, nickel-plated aluminum, and 316 stainless steel. Air
valves come in brass, nickel-plated brass or 316 stainless steel. A variety of
diaphragms, valve balls, valve seats and o-rings are available to satisfy
temperature, chemical compatibility, abrasion and flex concerns. All o-rings
used in the pump are of a special material and shore hardness that should only
be replaced with factory-supplied parts.
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 A15 Accu-Flo™ pumps are the same
except for the air distribution system.
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.
Step 2
Utilizing the 11/16" box wrench, remove
the two small clamp bands that fasten the
discharge manifold to the liquid chambers.
Step 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.
