•
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
pump’s base plate should be placed on loose fitting wedges
or shims located near each anchor bolt. Intervals between
the wedges or shims should be less than 24” per side.
•
Wedges or shims should raise the bottom of the pump about
¾ - 1¼ inches in order for there to be room for slurry.
Wedges and shims should be adjusted to make the pump
level using a spirit level.
•
Make sure that piping is aligned so as not to place stress on
either flange.
•
Once the pump is aligned, putting on bolt nuts and tightening
them will be sufficient to anchor the pump to the steel or
concrete foundation.
•
Once any grout is completely hardened, tighten the
foundation bolts as necessary. If tightening occurs then
recheck pump alignment.
