INSTALLATION
Foundations
The foundation should be substantial in order to reduce vibrations, and rigid enough to prevent flexing
which can result in misalignment. Foundation bolts of the correct size should be located by reference
to certified drawings if the baseplate is supplied with the pump.
The pump must be mounted horizontally on a level foundation, with the discharge port vertically
upwards.
The pumpset should be mounted on a level horizontal base. The base should be of sufficient rigidity to
prevent flexing. When bolting the pump down, insert shims as necessary under the pump feet to level
the pump using a spirit level on the suction and discharge flanges of the pump. Use all six bolt holes to
mount the pump.
Motor-pump units on baseplates
Level the baseplate accurately, using shims under the base-plate next to the foundation bolts. The
baseplate must sit firmly and evenly on its foundation: it must not be distorted by bolting to an uneven
surface, which will throw the pump and motor out of alignment.
Isolate the supply
before commencing
work on the pump.
