cals, dyes, detergents, waxes, gels, solutions with
suspended solids and emulsions.
METAL PLATING: Filtration of plating solutions. Filling
and emptying vats. Adding chemicals for Ph balance.

AGRICULTURAL: Transferring liquid fertilizers, herbi-
cides and pesticides.
OPERATING INSTRUCTIONS
1. INSTALLATION – Pump may be mounted in any
position. The rotation of the pump shaft determines
the location of the pump’s intake and discharge
ports (Refer to dimensional drawing). Pump is
normally assembled at factory for clockwise rota-
tion (looking at end cover). If counter clockwise rota-
tion is desired, follow steps 1 and 2 of disassembly
and step 7 of assembly instructions to change direc-
tion of impeller blade deflection under cam.
2. MOTOR SELECTION – Pump head is designed to fit
a 145 TC Frame NEMA C-face motor. Motor should
be rated 1-1/2 horsepower at 1750 RPM with a ser-
vice factor of one. Due to high bearing loads, motor
should be ball bearing equipped with the front bear-
ing locked against axial movement. Motor should be
capacitor start and foot mounted.
3. SPEEDS – 100 RPM to the maximum shown in the
performance curves. For longer pump life, operate

Explosion hazard. Do not pump gasoline,
solvents, thinners or other flammable liquids.
To do so can cause an explosion resulting in
injury or death.
