operating instructions - Rusch-Pumpen Fabrik GmbH

Flow velocities should lie in the ranges 0.5 to 1 m/s in the suction line
and 2 to 3 m/s in the delivery line.
Gate valves should be built in on either side of the pump, so that the
pump can be dismantled from the system without draining the lines.
If hoses are used, it should be ensured that these are not kinked and
that their inside diameter is matched to that of the pump.
Where rotary seals with sealing fluid feed are used or, in the case of
pumps with heating or cooling arrangements, the auxiliary pipework
should also be attached to the correspondingly marked connection
points without applying any stress. Ensure that the auxiliary lines are
flushed clean before connection.
4.0 OPERATION ON THE PUMPS
4.1.1 COMMISSIONING OF CENTRIFUGAL PUMPS
After the specified work has been completed and checked, the pump
can be commissioned.
Before starting the driving machine, note the following items:
● Bearing housings equipped with an oil-sight glass must be filled with
oil up to the middle of the oil-sight glass. Suitable branded oils, e.g.
of viscosity class 15W-40, should be used. Bearing ousings without
oil-sight glass have already been provided with a grease fill in the
workshop.
● If cooling is provided, the cooling water must be turned on and the
flow must be checked.
● Fill the pump completely with the medium to be pumped, open the
shut-off valve on the suction side completely and the shut-off valve on
the pressure side by half.
● If installed, turn on the sealing and flushing liquid supplies. Fully open
the throttles.
