DESCRIPTION and SPECIFICATIONS:

The 3642 (closed-coupled) and 3742 (frame-mount-
ed) are single stage, end suction, centrifugal pumps
for water circulation, booster service, liquid transfer,
spraying systems, jockey pump and general service
pumping. Pumps are available in three different ma-
terials of construction: all iron, bronze-fitted and all
bronze.
Pump impellers are enclosed design for high efficien-
cy, threaded directly on the motor shaft.
Close-coupled units have NEMA standard frame mo-
tors with C-face mounting and threaded shaft exten-
sions. Frame mounted units can be coupled to motors
through a spacer coupling, or belt driven.

INSTALLATION
Location:
Locate pump as near liquid source as practical; below
level of liquid for repriming capability.
Allow adequate space for servicing and ventilation.
Protect the unit from weather and water damage due
to rain, flooding or freezing temperatures.
Close - Coupled Units
Units may be installed horizontally, inclined or
vertically with the motor above the pump.
NOTICE: DO NOT INSTALL WITH MOTOR BELOW
PUMP. ANY LEAKAGE OR CONDENSATION
WILL AFFECT THE MOTOR.

Foundation:

A flat and substantial foundation surface MUST be
provided to avoid distortion and/or strain when
tightening the foundation bolts. A rubber mounting is
acceptable to reduce noise or excessive vibration.
Tighten motor hold-down bolts BEFORE connecting
piping to pump.

Bedplate must be grouted to a foundation with solid
footing. Refer to Figure 1.
Place unit in position on wedges located at four
points, two below approximate center of driver and
two below approximate center of pump. Adjust wedg-
es to level unit. Level or plumb suction and discharge
flanges.
Make sure bedplate is not distorted and final coupling
alignment can be made within the limits of movement
of motor and by shimming, if necessary.
Tighten foundation bolts finger tight and build dam
