Flushing fluid.
The choice of flushing fluid is
dependent upon the fluid being pumped and
duty conditions i.e. pressure and
temperature. Usually water is used for cooling
or flushing water-soluble products. For both
single flushed and double mechanical seal
arrangements the temperature of the flush
media should never be allowed to exceed the
maximum temperature of the pumped media.
For advice on selecting a suitable flushing
fluid please contact pump supplier.
