Goulds Pumps VIC - IOM - Manual (Page 19)

8. Tighten the foundation bolts.
Install the pump on a structural-steel foundation
1. Locate the barrel and pump directly over - or as near as possible to - the main building members,
beams, or walls.
2. Bolt the barrel or sub-base to the support in order to avoid distortion, prevent vibration, and retain
proper alignment.
3. Level the barrel or sub-base using shims.
Piping checklists
General piping checklist
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.
NOTICE:
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.
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.
Checklist
Check Explanation/comment Checked
Check that all piping is supported
independently of, and lined up
naturally with, the pump flange.
This helps to prevent:
• Strain on the pump
• Misalignment between the pump and the drive unit
• Wear on the pump bearings, seal, and shafting
Check that only necessary fittings
are used.
This helps to minimize friction losses.
Do not connect the piping to the
pump until:
• The grout for the barrel or sub-
base has hardened.
• The hold-down bolts for the
pump are tightened.
—
Make sure that all the piping
joints and fittings are airtight.
This prevents air from entering the piping system or
leaks that occur during operation.
If the pump handles corrosive
fluids, make sure that the piping
allows you to flush out the liquid
before you remove the pump.
