Precautions
CAUTION:
• Never draw piping into place by using force at the flanged connections of the pump. This can
impose dangerous strains on the unit and cause misalignment between the pump and driver. Pipe
strain adversely affects the operation of the pump, which results in physical injury and damage to
the equipment.
• Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the
suction side. This action can result in decreased performance, unexpected heat generation, and
equipment damage.
CAUTION:
Piping guidelines
Guidelines for piping are given in the Hydraulic Institute Standards available from the Hydraulic
Institute at 9 Sylvan Way, Parsippany, NJ 07054-3802. You must review this document before
you install the pump.
