8. Tighten the foundation bolts.

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.

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.

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 to 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 discharge-

head base flange or sub-base
has hardened.

• The hold-down bolts for the

pump have been 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.
