OPERATING INSTRUCTIONS
1. INSTALLATION - Pump may be mounted in any posi-
tion. 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 rotation (looking at
end cover). If counter clockwise rotation is desired,
follow steps 1 and 2 of dis as sem bly and step 12 of
assembly instructions to change direction of impeller
blade deflection under cam.
2. DRIVE - Belt or Direct with flexible coupling.
BELT DRIVE - Overtight belt load will reduce
bearing life.
DIRECT DRIVE - Clearance should be left
between drive shaft and pump shaft when
installing coupling. Always mount and align pump
and drive shaft before tightening the coupling
set screw.
NOTICE: If drive pulley or coupling must be pressed
on shaft, remove end cover and impeller and sup-
port shaft from impeller end during press operation.
Do not hammer a pulley or coupling on shaft. Failure
to follow above instructions can damage the
pump.
