GENERAL
WARNING
!
DISCONNECT PUMP FROM ELECTRICAL
POWER SOURCE PRIOR TO MAKING REPAIRS
OR ADJUSTMENTS TO ANY ELECTRIC
COMPONENTS OF THE UNIT. Elementary rules
of cleanliness, periodic inspections, and a
preventative maintenance policy of the pump
will produce optimum performance and prolong
the life of the pump.
SHAFT BEARINGS
The two shaft bearings should be lubricated every
1,500 hours of operation or every two months. A
high-temperature grease with an extreme-pressure
(EP) additive is recommended. Grease should be
added through the grease
¿
tting while the shaft is
turning. The temperature of the bearings should
not exceed 140°F (60°C) (hot to touch), unless
special grease is being used after consulting Tuthill
Vacuum & Blower Systems.
SCALE OR RUST ACCUMULATION
If scale or rust accumulates and hampers the
ef
¿
ciency of the pump, remove the scale or rust by
circulating an inhibitor selected according to the
nature of the buildup.
MECHANICAL SHAFT SEALS
If the mechanical seals are leaking, replace or
recondition them. Some mechanical shaft seal
manufacturers have a seal reconditioning program,
which we recommend where available.
When replacing the mechanical seal, clean the
shaft thoroughly where the previous seal may
have bonded to the shaft. The assembly drawings
and parts lists beginning
on page 32 show the
mechanical shaft seals that are commonly used
on Kinney liquid ring pumps. The seal faces must
be protected during installation from particles
that may scratch the surfaces. Before installing
the elastomers, the shaft and elastomers should
be lubricated with a lubricant compatible with the
pumping process for ease in installing and better
positioning on the shaft.
CAUTION
!
Do not run the mechanical seal without
coolant.
