DISCHARGE PIPING
1.
Isolation and check valves should be installed in
discharge line. Locate the check valve between
isolation valve and pump, this will permit inspection of
the check valve. The isolation valve is required for
priming, regulation of flow, and for inspection and
maintenance of pump. The check valve prevents pump
or seal damage due to reverse flow through the pump
when the driver is turned off.
2.
Increasers, if used, should be placed between pump
and check valves.
3.
Cushioning devices should be used to protect the
pump from surges and water hammer, if quick-closing
valves are installed in system.
FINAL PIPING CHECK
After Connecting Piping to the Pump
!
Rotate shaft by hand to ensure it rotates smoothly
and there is no rubbing which could lead to excess
heat generation and or sparks.
1.
Rotate shaft several times by hand to be sure that there
is no binding and all parts are free.
2.
Check alignment, per the alignment procedure outlined
previously to determine absence of pipe strain. If pipe
strain exists, correct piping.
!
A build up of gases within the pump, sealing system
and or process piping system may result in an
explosive environment within the pump or process
piping system. Ensure process piping system, pump
and sealing system are properly vented prior to
operation.
