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.
Frame-Mounted Units:
DESCRIPTION and SPECIFICATIONS:
The 3642 (closed-coupled) and 3742 (frame-mounted) 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 materials of construction: all iron, bronze-fitted and all
bronze.
Pump impellers are enclosed design for high efficiency, threaded directly on the motor shaft.
Close-coupled units have NEMA standard frame motors with C-face mounting and threaded shaft extensions. Frame mounted units can be coupled to motors
through a spacer coupling, or belt driven.
ENGINEERING DATA
Maximum Liquid Temperature:
212º F (100º C) – standard seal
250º F (120º C) – Optional high temp. seal
Maximum Working Pressure: 125 psi
Figure 1
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 wedges 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
around foundation. Pour grout under bedplate mak-

PIPING
Piping should be no smaller than pump’s discharge
and suction connections and kept as short as possible,
avoiding unnecessary fittings to minimize friction
losses.
All piping MUST be independently supported and
MUST NOT place any piping loads on the pump
NOTICE: DO NOT FORCE PIPING INTO PLACE
AT PUMP SUCTION AND DISCHARGE
CONNECTIONS.
All pipe joints MUST be airtight.
Piping – Suction
For suction lifts over 15 ft. (4.6 m), consult pump performance curve for net positive suction head required
(NPSHR).
If a pipe size larger than pump suction is required,
an eccentric pipe reducer, with the straight side up,
MUST be installed at the pump suction.
If pump is installed below the liquid source, install
a gate valve in the suction for pump inspection and
maintenance.
NOTICE: DO NOT USE THE GATE VALVE TO
THROTTLE PUMP. THIS MAY CAUSE LOSS
OF PRIME, EXCESSIVE TEMPERATURES
AND DAMAGE TO PUMP, VOIDING
WARRANTY.
If the pump is installed above the liquid source, the
following MUST be provided:
To avoid air pockets, no part of the piping should
be above the pump suction connection.
Slope the piping upward from liquid source.
Use a foot valve or check valve ONLY if neces-
sary for priming or to hold prime during intermittent duty.
The suction strainer or suction bell MUST be at
least three times the suction pipe diameter area.
Insure that the size and minimum submergence
over suction inlet is sufficient to prevent air from
entering pump through a suction vortex. See Figures 2 through 5.
Piping – Discharge
Install a check valve suitable to handle the flow, liquids and to prevent backflow. After the check valve,
install an appropriately sized gate valve to be used to
regulate the pump capacity, pump inspection and for
maintenance.
When required, pipe increaser should be installed
between the check valve and the pump discharge.

WIRING AND GROUNDING
Install, ground and wire according to local and National
Electrical Code Requirements.
Install an all leg disconnect
switch near the pump.
Disconnect and lockout electrical power before installing or
servicing the pump.
Electrical supply MUST match pump’s nameplate specifications. Incorrect voltage can cause
fire, damage to the motor and voids the warranty.
Motors not protected MUST be provided with
contactors and thermal overloads for single
phase motors, or starters with heaters for three
phase motors. See motor nameplate.
Use only copper wire to motor and ground. The
ground wire MUST be at least as large as the wire to
the motor. Wires should be color coded for ease of
maintenance.
Follow motor manufacturer’s wiring diagram on the
motor nameplate or terminal cover carefully.

Parallel misalignment (shafts with axis parallel but not
concentric). Place dial indicator on one hub and rotate
this hub 360º while taking readings on the outside diameter of the other hub. Parallel alignment is achieved
when reading is 0.005” (0.127 mm) TIR, or less.
Angular misalignment (shaft with axis concentric but
not parallel). Place dial indicator on one hub and
rotate this hub 360º while taking readings on the face
of the other hub. Angular alignment is achieved when
reading is 0.005” (0.127 mm) TIR, or less.
Final alignment is achieved when parallel and angular
requirements are satisfied with motor hold-down bolts
tight.
NOTICE: ALWAYS RECHECK BOTH ALIGNMENTS
ROTATION
NOTICE: INCORRECT ROTATION MAY CAUSE
Correct rotation is right-hand, CLOCKWISE when
viewed from the motor end. Remove motor end plug
or cover to observe rotation.
To reverse three phase motor rotation, interchange
any two power supply leads.

After stabilizing the system at normal operating conditions, check the piping. If necessary, adjust the pipe
supports.
On frame-mounted units, coupling alignment may
have changed due to the temperature differential
between pump and motor. Recheck alignment following procedures and hazard warnings in “COUPLING
ALIGNMENT” section of this manual.
