MOUNTING THE MOTOR AND ALIGNING THE COUPLING:
ALIGNMENT FOR VERTICAL PUMPS:
On pedestal mounted Pumps, the motor supports are indexed (top and bottom) to maintain factory
alignment. FLEXIBLE COUPLINGS: Flexible couplings are used to compensate for temperature changes
and to prevent interference between pump shaft and motor shaft during operation.
They are NOT to be used to compensate for misalignment of the motor and pump shafts. The flexible
coupling is aligned at the factory, but the unit is shipped with the coupling halves separated and requires
rechecking before field conneetions are made. The following procedure applies to factory standard
couplings only. When special couplings are provided, the specific manufacturer's instructions will be
supplied and must be strictly adhered to. If questions arise as to the type of coupling supplied with the
unit, contact your CHICAGO PUMP representative.
The maximum parallel offset for factory standard couplings is .015", and the maximum angular offset is
one (1) degree between pump shaft and motor shaft. Alignment is checked with the flexible sleeve
removed. Using a straightedge and feeler gauges, check for proper alignment on two mutually
independent perpendicular planes. Use the feeler
gauge to measure the offset, and place shims under the pump or motor to compensate for any
misalignment.
