If the pump is to be mounted on a steel frame, or similar structure, it should be set directly over
the supporting beams. These beams and the structure must be rigid enough to prevent
distortion and potential misalignment due to movement within the structure or base.
The location of this structure should be as close as possible to the pumpage source. Provide
adequate space for operation, maintenance and inspection of the pump and equipment.
The concrete foundation should be provided with anchor bolts for attachment to the base plate.
If required, provide adequate drainage to keep pump and motor dry and clean. Also, provide
either leveling nuts or leveling wedges for mounting the base plate to the foundation.
LEVELING
When mounting the base plate to the foundation use the leveling nuts or wedges to provide a
level, flat base plate. Use a machinist's level on the mounting pads and make adjustments as
necessary as the anchor bolts are tightened. This will provide the true alignment between the
pump and motor.
GROUT
If this base plate is to be grouted, ensure that you have the mounting surface flat and level for
correct alignment of pump and motor. Build a dam around the base plate perimeter that is to be
watertight. Use standard grouting practice and be sure to protect (cover) the leveling wedges
with caulk or plastic tape if they are to be removed later. After the grout has thoroughly
hardened, remove forms. If the wedges are removed, fill holes with grout. Seal grout by
covering with a quality paint or sealer.
TRAILER MOUNTED UNITS
See "OPERATION" section.
INSTALLING PUMP
Ensure that all foreign material has been removed from the pump before mounting. Be sure to
remove all shipping protection prior to operation.
NOTE: Many of the bare pumps are shipped with protective guards and coatings.
SUCTION PIPING
For best performance the suction piping should be at least as large as the pump flange, never
smaller. Use an eccentric reducer at the suction flange with the straight side up. The use of
flow-retarding fittings is to be avoided and if necessary should never be placed closer to the
pump suction than four (4) times the pipe diameter. The pump should be at the highest point of
the piping. Slope the piping up to the pump to prevent air pockets and avoid changing pipe
size with the exception of the eccentric reducer mentioned above. All suction piping and
fittings are to be checked for any foreign material (rocks, bolts, wire, etc.) and also any sharp
burrs that could disrupt the flow.
