3.2 Preparation
Before installing the pump, clean the suction and discharge flanges thoroughly.
Remove the protective coating from the pump shaft.
If the pump has been in storage and prepared for storage in the manner outlined
previously, remove all the grease from the bearings. The bearings should then be
flushed with carbon tetrachloride or kerosene and relubricated.
3.3 Location
The pump should be installed as near the suction supply as possible, with the
shortest and most direct suction pipe practical. The total dynamic suction lift (static lift
plus friction losses in suction line) should not exceed the limits for which the pump was
sold.
The pump must be primed before starting. Whenever possible, the pump should be
located below the fluid level to facilitate priming and assure a steady flow of liquid. This
condition provides a positive suction head on the pump. It is also possible to prime the
pump by pressurizing the suction vessel.
Pumps must be fully primed at all times during operation.
When installing the pump, consider its location in relation to the system to assure that
sufficient Net Positive Suction Head (NPSHA) is available at the pump inlet connection.
Available NPSH must always equal or exceed the required NPSH (NPSHR) of the pump.
The pump should be installed with sufficient accessibility for inspection and
maintenance. A clear space with ample head room should be allowed for the use of an
overhead crane or hoist sufficiently strong to lift the unit.
NOTE: Allow sufficient space to be able to dismantle pump without disturbing the
pump inlet and discharge piping.
