Disassembly
Before disassembling pump, ensure that
the pump driver has been turned off and tagged
to prevent operation, and that the pump has
been isolated from all systems, and that all fluids
have been depressurized and drained. When
venting or draining any vessel which contains
toxic, flammable, or otherwise hazardous fluids,
ensure that the vented or drained fluid is piped
to a safe collector which will prevent release of
the fluid into the surrounding area. Do not
breathe toxic vapors. Failure to do so can result
in equipment damage, personnel injury, or death.
6.7.1 General instructions
6.7.1.1 Items and details excluded from
instructions
Since removal, installation, and tightening
procedures for common hardware such as bolts,
nuts, keys, and connectors are apparent to the
journeyman millwright, detailed steps for handling
such hardware, where it is external to the pump, are
not included in the repair tasks. Accordingly,
removal and installation procedures are not included
for piping, coolers, oil filter, and instruments (gauges,
thermometers etc.). Unless there is a handling
requirement that is peculiar to the pump, specific
lifting and related rigging instructions are not given in
this manual.
6.7.1.2 Disturbing an installation
It is unnecessary to disconnect the pump's suction
and discharge piping or to change the position of
either pump or driver except to remove it from the
baseplate. Auxiliary piping should be disconnected
only at such points as necessary for the removal of a
part of the pump. When piping is disconnected,
clean material such as plastic should be securely
