8. Installation
8.1 Pump location
Locate the pump in a dry, well-ventilated, frost-free area which is
not subject to extreme variation in temperature.
Make sure the pump is mounted at least 6 inches (150 mm) clear
of any obstruction or hot surfaces.
The motor requires an adequate air supply to prevent overheating
and adequate vertical space to remove the motor for repair.
In open systems requiring suction lift, locate the pump as close to
the liquid source as possible to reduce friction loss in pipes.
8.2 Foundation
Use concrete or similar foundation material to provide a secure,
stable mounting base for the pump.
See table below for bolt hole center line dimensions for the
various pump types.
Secure the pump to the foundation using all four bolts and shim
pump base to assure the pump is vertical and all four pads on the
base are properly supported (uneven surfaces can result in pump
base breakage when mounting bolts are tightened).
Fig. 4 Pump position
The pump can be installed vertically or horizontally. See fig. 4.
Ensure that an adequate supply of cool air reaches the motor
cooling fan. The motor must never fall below the horizontal plane.
Arrows on the pump base show the direction of flow of liquid
through the pump.
To minimize possible noise from the pump, it is advisable to fit
expansion joints on either side of the pump and anti-vibration
mountings between the foundation and the pump.
Fit isolating valves on either side of the pump to avoid draining
the system if the pump needs to be cleaned, repaired or replaced.
Warning
Do not turn on the power supply until the pump is
properly installed.
