3.4.5.1
Cooling of the shaft seal housing –
Cooling of the shaft seal housing is recommended when the temperature of the
liquid to be pumped exceeds 90
°
C. The cooling water requirement depends on
the temperature of the pumping liquid and on the pump size. It is about 2 l/m at
max. 2 bar. The cooling liquid enters the housing in the upper section of the
pump foot, whereas it drains off diagonally across on the opposite side [see Fig.
3].
3.4.6
Sealing liquid connection for pump with stuffing box –
It is recommended to use stuffing box sealing.
3.4.7
Operating of the pump used as boiler feed pump –
When the pump is employed as boiler feed pump, care must be taken that it is not
run at a lower operating pressure than specified. If the feed tank is operated at a
lower operating pressure for any length of time, the pump discharge pressure must
be reduced to the normal operating pressure of the tank by means of a hand
operated shut off valve and a pressure gauge fitted at the discharge nozzle of the
pump casing.
