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
Check that all piping is
supported independently of, and
lined up naturally with, the pump
flange.
Keep the piping as short as
possible.
Check that only necessary fittings
are used.
Do not connect the piping to the
pump until:
• The grout for the baseplate or
sub-base becomes hard.
• The hold-down bolts for the
pump and the driver are
tightened.
Make sure that all the piping
joints and fittings are airtight.
If the pump handles corrosive
fluids, make sure that the piping
allows you to flush out the liquid
before you remove the pump.
If the pump handles liquids at
elevated temperatures, make sure
that the expansion loops and
joints are properly installed.

Explanation/comment
This helps to prevent:
• Strain on the pump
• Misalignment between the pump and the drive unit
• Wear on the pump bearings and the coupling
• Wear on the pump bearings, seal, and shafting
This helps to minimize friction losses.
This helps to minimize friction losses.
—
This prevents air from entering the piping system or
leaks that occur during operation.
—
This helps to prevent misalignment due to linear
expansion of the piping.
