4 Installation
To ensure optimum operation it is important that any pump unit is installed correctly. When designing a pumping system the
following should be taken into consideration.
C Coouupplliinngg aalliiggnnm meenntt::
Before the pump unit is installed is it important to ensure that the mounting surface is flat to avoid distortion of the baseplate,
which may cause pump/motor shaft misalignment and pump/motor unit damage. Once the baseplate has been secured, the
pump shaft to motor shaft coupling alignment should be checked and adjusted as necessary. This is achieved by checking
the maximum angular and parallel misalignment for the couplings as stated below. Shaft alignment that is outside the stated
tolerances can be corrected by applying shims under the motor or pump foot, or, by moving the pump or drive sideways on
the baseplate. All bolts that have been loosened should be re-tightened to the stated torque figure.
