Liquiflo Installation, Operation & Maintenance Manual
Section 3: Pump & Motor Installation
3.1

Installation of Pump, Motor and Base

Refer to the Hydraulic Institute Standards for proper installation procedures of the base, pump and motor.
Observe the following guidelines:
1) The foundation area must be rigid and level for maintaining pump alignment.
2) The pump and motor assembly must be securely fastened to the base, and the base must be
securely attached to the ground.
3) The pump inlet should be as close to the liquid source as practical and preferably below it.
4) The pump and motor should be accessible for servicing and inspection.
5) The pump and motor should be cleaned periodically to prevent the build-up of dust.
NOTE: The pump models covered in this manual are close-coupled and no alignment procedure between
the pump and motor is required.
3.2

General Piping Requirements

Guidelines for piping are given in the Hydraulic Institute Standards and should be reviewed prior to pump
installation.
1) All piping must be supported independently and must line up naturally with pump ports.
CAUTION! Do not use the pump to support the piping or allow the piping
to apply stress to the pump ports. This can distort the alignment of the
pump housing with internal parts and lead to rapid wear or malfunction.
2) DO NOT make final connection of piping to pump until the grout has hardened and the pump and
motor hold-down bolts have been tightened.
3) Piping that handles both hot and cold liquids require proper installation of expansion loops and
joints so that thermal expansion of the piping will not cause misalignment.
4) Gasket installation and materials must be suitable for the service.
5) Piping runs should be designed to minimize friction losses.
6) Suction and discharge piping should be the same size or larger than the inlet and outlet ports.
7) The piping should be arranged to allow the pump to be flushed and drained prior to the removal
of the pump for servicing. Valves and unions should be installed to allow the pump to be isolated
during maintenance.
8) The piping system should be thoroughly cleaned prior to installation of the pump.
