4.6.5 Pump and shaft alignment check
After connecting the piping, rotate the pump drive
shaft clockwise (view from motor end) by hand
several complete revolutions to be sure there is no
binding and that all parts are free. Recheck shaft
alignment (see section 4.5). If piping caused unit to
be out of alignment, correct piping to relieve strain on
the pump.
4.6.6 Auxiliary piping
4.6.6.1 Mechanical seal
When the pump is intended to be equipped with a
mechanical seal, it is Flowserve standard practice to
install the mechanical seal in the pump prior to
shipment. Specific order requirements may specify
that the seal be shipped separately, or none be
supplied. It is the pump installer’s responsibility to
determine if a seal was installed. If a seal was
supplied but not installed, the seal and installation
instructions will be shipped with the pump.
Failure to ensure that a seal is installed
may result in serious leakage of the pumped fluid.
Seal and seal support system must be installed and
operational as specified by the seal manufacturer.
The stuffing box/seal chamber/gland may have ports
that have been temporarily plugged at the factory to
keep out foreign matter. It is the installer’s
responsibility to determine if these plugs should be
removed and external piping connected. Refer to the
seal drawings and or the local Flowserve
representative for the proper connections.
When installing piping, do not install metal pipe
fittings directly into the non metallic threaded
connections on the pump. If metal pipe fittings must
be used, then install a non metallic pipe nipple into
the connection on the pump and then connect metal
pipework to this nipple.
