Pump Piping Connections
Minimizing Excessive Loads/ Pipe Stress
• Do not use the pump as an anchorage point
for the piping.
• Anchor the pipelines in close proximity
to the pump and connect them without
transmitting any stresses or strains.
Piping Alignment
• Accurate alignment and support of all piping
connected to the pump is critical.
• Any movement occurring at the inlet
or discharge connections may cause
misalignment and stress over time.
• Do not force any misaligned pipes to
connect to the pump discharge or inlet.
Pipe Coupling Connections
• Follow all manufacturer installation and
torque specications.
• Align all piping carefully before installing
couplings.
• Make sure all seals seat correctly inside
the coupling. If piping or seals are not
aligned correctly, leaking may occur under
pressure.
• Provide for expansion or contraction
of piping. Always consider best setting
for pipe end gaps for handling angular
deection and combinations of expansion
and contraction. Separation and deection
recommendations are specied on the
following page.
