4.2.3 Piping checklists
4.2.3.1 General piping checklist
Install the pump on a structural-steel foundation
1.
Locate the pump directly over, or as near as possible to the main building members, beams, or
walls.
2.
Bolt the discharge-head mounting flange, or sub-base to the support in order to avoid distortion,
prevent vibration, and retain proper alignment.
3.
Level the sub-base or discharge head using shims.
Precautions
WARNING:
•
Risk of premature failure. Casing deformation can result in misalignment and contact with
rotating parts, causing excess heat generation and sparks. Flange loads from the piping
system, including those from the thermal expansion of the piping, must not exceed the
limits of the pump as defined on the Certified Outline Drawing.
•
Risk of serious personal injury or property damage. Fasteners such as bolts and nuts are
critical to the safe and reliable operation of the product. Ensure appropriate use of fasten-
ers during installation or reassembly of the unit.
•
Use fasteners of the proper size and material only.
•
Replace all corroded fasteners.
•
Ensure that all fasteners are properly tightened and that there are no missing fas-
teners.
CAUTION:
Do not move the pump to the pipe. This could make final alignment impossible.
CAUTION:
Never draw piping into place at the flanged connections of the pump. This can impose danger-
ous strains on the unit and cause misalignment between the pump and driver. Pipe strain ad-
versely affects the operation of the pump, which results in physical injury and damage to the
equipment.
Flange loads from the piping system, including those from the thermal expansion of the piping,
must not exceed the limits of the pump. Discharge head deformation can result in contact with
rotating parts, which can result in excess heat generation, sparks, and premature failure.
NOTICE:
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.
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.
