DESCRIPTION and SPECIFICATIONS
The series 3656/3756 are single stage, end suction, centrifugal
pumps for general liquid transfer, booster applications, irriga-
tion and general service pumping. Pumps are available in three
different materials of construction: all iron, bronze-fitted and
all bronze ("S" group only).
Pump impellers are fully enclosed, key driven and held in
position by an impeller bolt and washer. Casings are full volute
in design with replaceable wear rings.
Dependant on the pump size, the suction and discharge
connections will be threaded or flanged. Shafts are protected
with stainless steel shaft sleeves.
Close-coupled units have NEMA standard JM or JP motors
with C-face mounting and key driven shaft extension. SAE
drive units bolt directly to the engine flywheel housing for SAE
sizes 1, 2, 3, 4 or 5. Optional elastomer element couplings
are available for 6½, 7½, 8, 10, 11½ and 14 inch flywheels.
Frame mounted units can be coupled to motors through a
spacer coupling, or belt driven.

Installation
loCATion
• Locate the pump as near liquid source as practical; below
level of liquid for automatic repriming capability.
• Allow adequate space for servicing and ventilation. Protect
the unit from weather and water damage due to rain,
flooding or freezing temperatures.
• Protect the pump and piping from freezing temperatures.
• Allow adequate space around the unit for service and
ventilation.
CloSE-CoUPlED UniTS
• Units may be installed horizontally, inclined or vertically with
the motor above the pump.
• The motor feet MUST be bolted to a substantial surface
(horizontal or vertical) that is capable of complete and rigid
support for the pump and motor. For L-Group pumps, the
motor adapter feet must also be bolted to the supportive
surface.
• For vertical operation, the motor should be fitted with a drip
cover or otherwise protected against liquid entering the mo-
tor (rain, spray, condensation, etc.)
NOTICE: DO NOT INSTALL WITH MOTOR
BELOW PUMP . ANY LEAKAGE OR
CONDENSATION WILL AFFECT
THE MOTOR.
