GENERAL

This manual contains installation, operation, cleaning, and repair instructions, with parts list, for the
SP Series base mounted pumps manufactured by Tri-Clover, Inc. of Kenosha, Wisconsin.  It also
provides a troubleshooting chart to aid in determining pump malfunctions.

DESCRIPTION

The SP Series pump units are generally mounted on base plates which accommodate both the
pump units and the drive motors.

The pump units are comprised of two sections, the power frame section which transmits power
from the motor to the pump and the liquid end or pump section.  The pump impeller is mounted to
the power frame shaft and is secured by a floating retainer or by a threaded shaft and castellated
nut.  The casing is clamped to the power frame, greatly simplifying removal, and permitting
positioning of the discharge outlet through 360°.

Three basic standard seal designs, external balanced seal, packing gland, and water cooled
balanced double seal, insure long seal life and optimum pump performance for all applications.  A
wide variety of commercial seals are also available for special applications.  Consult the factory for
seal parts lists and service instructions.

WARNING

Before servicing pump, disconnect electrical
power source.
