Pump Wet End Assembly
To assemble the wet end of the pump, reverse the order of disassembly. Ensure all
hardware is fastened in accordance with torque specifications (see page 18). In
-
verting one of the diaphragms during reassembly will facilitate ease of assembly.
NOTE: When using pumps built with PTFE O-Rings, always replace with new PTFE
O-Rings, since the original O-Rings may not reseal the pump.

In order to remove both “Outer Cham
-
bers”, using two 3/4 inch wrenches
(or socket), remove ten “Hex Head Cap
Screws”, “Washers”, “Lock Washers”
and “Nuts” from each side. Note the
lower four bolts are inserted from the
center.
STEP 8
Remove both “Outer Chambers” and
“Power Rings” from the “Intermediate”.
Note the “Lock Washers” are installed
on the “Power Rings” which should be
on the “Intermediate” side.

Using two 1-1/4 inch wrenches, re-
move “Outer Diaphragm Plate”, “Dia-
phragm”, “Inner Diaphragm Plate” and
“Custom Washer” from one side of the
pump.

Placing the 1-1/4 inch wrench on the remaining “Outer Diaphragm Plate” and the
3/4 inch wrench on the “Diaphragm Rod Assembly”, remove the remaining “Outer
Diaphragm Plate”, “Diaphragm”, “Inner Diaphragm Plate” and “Custom Washer”
