6.7 Pump removal and disassembly
a)
Before performing any maintenance, disconnect
the driver from its power supply and lock it off line.
Lock out power to driver to prevent
personal injury.
b)
Close the discharge and suction valves, and
drain all liquid from the pump.
c)
Close all valves on auxiliary equipment and
piping, then disconnect all auxiliary piping.
d)
Decontaminate the pump as necessary.
If Flowserve PolyChem M-series
pumps contain dangerous chemicals, it is important to
follow plant safety guidelines to avoid personal injury
or death.
Small amounts of liquid may be trapped in the
casing and/or containment area. Proper
decontamination is the responsibility of the user.
Drain and flush the pump before proceeding.
The PolyChem M-series pump is designed to handle
corrosive, toxic, and hazardous process fluids and
may need to be decontaminated prior to any
disassembly
