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 15). Inverting one of the diaphragms during reassembly will
facilitate ease of assembly.
When positioning clamps use soapy water or a compatible lubricating
spray on the inside of band clamps to aid assembly. Tap with a mallet
on the outside of clamp to help position the clamp while tightening the
fasteners. The band clamp fasteners and cap screws are stainless steel.
To prevent galling always apply an anti-seize compound to the thread.
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.
STEP 7
In order to remove both “Outer
Chambers”, using the ½
inch
wrench, remove the “Chamber
Clamps” from each side of the
“Intermediate”.
STEP 10
Placing the ¾ inch wrench on the remaining “Outer Diaphragm Plate” and the straight blade screwdriver on
the “Diaphragm Rod”, remove the remaining “Outer Diaphragm Plate”, “Diaphragm” and “Inner Diaphragm
Plate” (washer) from the other side of the pump.
Note PTFE diaphragms also contain an O-Ring on the “Intermediate” side.
STEP 8
Remove both “Outer Chambers”

Using two ¾ Inch wrenches,
