applied to turn the element, as this could cause
further, and possibly severe damage to the
internal components. The rotating element
should be pulled from the pump casing, and the
internal wear parts and rotor cleaned.
Piping to the pump should be supported to
prevent excess nozzle loads. Please refer to a
certified copy of the general arrangement
drawing for allowable piping forces and
moments values. These values are for
operational allowances and are not given to
excuse excessive pipe strain.
Excessive pipe strain can adversely affect
alignment, and the subsequent life of the pump.
LIFTING
The lifting of the complete pump should be
done on the body of the casing, inboard of the
bearing housing hanger brackets. Do not
support directly on the bearing housings as this
could affect the alignment of the rotating
element in relationship to the internal stationary
parts. Do not try to lift the complete pump by the
top half “cast” lifting lugs. The cast lifting lugs in
the top half casing is designed for lifting of the
top half only.
The motor should be lifted per the motor
manufactures recommended lifting instructions.
Normally the lifting lugs provided on the top of
the motor are adequate for lifting. Magnetically
centered rotors should be secured to prevent
movement of the rotor, and subsequent damage
to the sleeve bearings. The rotors are normally
secured with a bracket on the drive end shaft
extension.
For the lifting of the complete skidded
package, lifting lugs are provided on the skid,
which per API are capable of lifting the entire
package. A spreader bar is recommended for
lifting of the entire unit. Refer to a certified
general arrangement drawing for lifting weights
and center of gravity of the unit.
PUMP INSTALLATION
Normally the pump is secured to the base
plate upon shipment. However, if the was not
shipped on the base plate, or was removed
during the grouting process, the pump should be
lifted and positioned on the pedestals, centering
the foot mounting holes. The pump is to mount
directly on the pedestals, without the use of
shims.
The pump mounting feet should be checked
to ensure that no soft foot condition exists.
During base shipment, lifting, and installation
processes, distortion of the base plate could
occur. With a dial indicator, check each foot by
setting the indicator in a vertical position, zeroing
the dial, and tightening the foot bolt. Record the
reading and loosen. Move to the next foot and
repeat. When all feet are checked, a minimal
amount of shims should be added to the “soft”
feet, only as necessary to eliminate the soft foot
condition. Shims should be stainless steel, and
