CAUTION:
• Do not move the pump to the pipe. This could make final alignment impossible.
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.

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 and the coupling
• Wear on the pump bearings, seal, and shafting
Keep the piping as short as pos-
sible.
This helps to minimize friction losses.
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 baseplate
or sub-base becomes hard.
• The grout for the pit cover
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.
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.
—
If the pump handles liquids at
elevated temperatures, make
sure that the expansion loops and
joints are properly installed.
This helps to prevent misalignment due to linear expan-
sion of the piping.
