3.4.5 Cooling of the shaft seal housing –
The shaft seal housing of pumps may be cooled as required. Unscrew the plugs
provided on the pump foot and connect the cooling lines.
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.
