TOOLS REQUIRED:
• 9/16" Wrench
• 3/4" Wrench
• Adjustable Wrench
• Vise equipped w/soft jaws (such as ply-
wood, plastic or other suitable material)
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.
NOTE: All O-rings used in the pump are
made of special material and at any of sign
of hardness should be replaced with only
factory-supplied parts.
Step 1.
Before starting disassembly, mark a line
from each liquid chamber to its corre-
sponding air chamber. This line will assist
in proper realignment during reassembly.
Step 2.
Using a 3/4" wrench, loosen the discharge
manifold from the liquid chambers.
Step 3.
Remove the discharge manifold to expose
the top-left valve ball.
NOTE: the HX400S pump does not use
valve balls in the amplification chamber.
Step 4.
Remove the discharge valve ball, valve seat
and valve seat O-ring from the left liquid
chamber and inspect for nicks, gouges,
chemical attack or abrasive wear. Replace
worn parts with genuine Wilden® parts for
reliable performance.
Step 5.
To ensure no excessive wear or damage has
occurred to the amplification chamber plug
O-rings, remove plugs located between top
and bottom tee sections and elbows (right
side of pump only). Inspect and replace
seat plug O-rings if necessary. Install Buna®
O-ring on air side of plug and the encapsu-
lated Viton® O-ring on liquid side of plug.
Step 6.
Using a 3/4" wrench, loosen the inlet mani-
fold from the liquid chambers.
