4.4 Pipework
All pipework MUST be supported. The pump
MUST NOT be allowed to support any of the
pipework weight.
Remember- Pipework supports must also
support the weight of the
product being pumped.
Always :-
Have - Short straight suction lines to
reduce friction losses in the
pipework thereby improving
the NPSH available.
Avoid - Bends, tees and any restraints
close to either suction or
discharge side of pump. Use
long radius bends wherever
possible.
Provide - Isolating valves on each side
of the pump to isolate the pump
when necessary.
Keep - Pipework horizontal where
applicable to reduce air locks.
Include eccentric reducers on
suction lines.
Check - Coupling alignment during
installation to highlight
pipework alignment/support
problems.
