Installation.
Location.
•
Place the pump as close to the suction source as
possible.
•
Suction piping should be as short and direct as possible.
•
Place the pump below the water level whenever possible.
This will facilitate priming, ensures a constant flow of liquid,
and provides a positive suction.
•
Make sure the NPSH (Net Positive Suction Head) is
accounted for at the suction end of pump relative to the
whole system. Available NPSH must always exceed the
required NPSH specified in the yield curve specifications of
the pump.
•
Always allow sufficient access for maintenance and
inspection, plus space for the use of a crane strong enough to
lift the unit.
•
Be sure to have an adequate power supply for the pump
motor. The electrical characteristics should fall within the
range specified on the engine data plate.
•
Protect the pump from exposure to extremely low
temperatures to prevent fluid inside the pump from freezing.
The foundation for a horizontal pump.
•
To absorb vibrations and prevent misalignment, horizontal
pumps should be permanently installed on foundations of
sufficient size, that are made of concrete or steel.
•
The foundation may either be on springs or on a raised
portion of the floor.
•
Concrete foundations must be poured without interruption. All
foundations must be between 3/4 to 1-1/2 inches below the
elevation of the end pump.
•
Anchor bolts should be in their designated positions along the
pipe sleeves, and be long enough to go through grout, flange,
nuts, and washers..
•
As the foundation needs time to set, the pump should be
installed several days after the foundation is laid.
•
Once the foundation (if concrete) is poured and set, the
