Pump Service
To remove the pumping units from the PrintClean, perform the following procedures:
•
Disconnect the PrintClean from the power or air source.
•
Remove the pump safety guard from the unit by unfastening the machine screws from the
motor/filter shelf.
•
Remove the motor cover by unscrewing all machine screws. Remove four machine screws on
motor/filter shelf to free up pump shelf assembly.
•
Remove each wire nut from the electrical cord and tag for re-assembly.
If your model has a Hydro-Jet manifold
(1” pipe), it can be removed by using a pipe wrench to
loosen. Swing (from back end) motor/filter shelf to the left to allow enough room for pipe wrench.
With the pipe removed, the whole pump/filter assembly can be swung (back end) to the left and lifted
out. Reverse the procedure when replacing the pump assembly.
Ensure pump shaft alignment after re-coupling with motor shaft.
Pump shaft must have
≤ 0.005” TIR.
If your model is equipped with external filters, they can be removed simply be unscrewing them from
the manifold:
See REPLACEMENT PARTS section for more information on replacement filter part numbers.
All models have double suction impellers with no set screws. They have a “D” shaped hole that is flush
with the shaft. A castle nut compresses shaft springs which adjusts impeller clearance. Insert cotter pin
to keep the nut from turning. All impellers should be close to the upper surface of the volute (impeller
chamber) and checked for rubbing. Assemble gasket and cover plates firmly with fasteners provided.
