PREVENTATIVE MAINTENANCE, DO’S & DON’TS
7.
Don’t use the pump in a system which includes a
steam blow or an air or vapor blow or purge without
provision for overspeed shutdown in case the pump
starts to act as a turbine and overspeeds the drive.
8.
Don’t operate the pump with all of the liquid
bypassing through a pump mounted internal type
pressure relief valve or without any flow of liquid
going through the pump for more than a couple of
minutes. Operation under either of these conditions
may result in a heat buildup in the pump which could
cause hazardous conditions or happenings.
9.
Do have spare parts, pumps or standby units
available, particularly if the pump is an essential part
of a key operation or process.
Maintenance
1.
Do make sure any pump that has residual system
pressure in it or that has handled high vapor pressure
liquids. e.g., LP-gas, ammonia, Freons, etc. has
been vented through the suction or discharge lines or
other openings provided for this purpose.
2.
Do make sure that if the pump is still hooked to the
driver while maintenance is being performed that the
driver has been "locked out" so that it cannot be
inadvertently started while work is being done on the
pump.
3.
Do make sure any pump that has handled a
corrosive, flammable, hot, or toxic liquid has been
drained, flushed, vented and/or cooled before it is
disassembled.
4.
Don’t drop parts during disassembly, e.g., idler can
slip from the pin as the head is removed from the
pump; it may drop on your foot, plus, it may get
nicked or gouged.
5.
Don’t stick fingers in the ports of a pump! The close
running parts may trim more than your fingernails if
the pump is rotated.
6.
Don’t spin the idler on the idler pin! Fingers may be
jammed between teeth and crescent.
7.
Do
remember
that
a
few
simple
preventative
maintenance procedures such as periodic lubrication,
adjustment of end clearance, examination of internal
parts, etc. will extend the service life of your pump.
Do obtain, read and keep maintenance instructions
furnished with your pump.
