When assembling the pump again, check the pump shaft for damages in the form of marks,
burrs, or upsetting of the shaft end.
Damages, if any, are to be remedied by means of a file and fine emery cloth. This work has to
be done very carefully. If this is not done carefully, the pump shaft will scratch the shaft seal
when fitted.

The following working pressures (pressure in piping incl. the pressure increase caused by the
pump) and number of revolutions are allowed in standard pumps.

The above max. operating pressure is valid at 180°C water
The above-mentioned max. working pressure is a design value
– delivered pumps are
pressure tested according to actual application requirements and actual flange standards.
For instance the above-mentioned max. working pressure is
NOT
valid for pumps approved
by a classification society. Pumps approved by classification societies have been pressure
tested according to the requirements of these societies, i.e. a test pressure of 1.5 x the
permissible working pressure. The test pressure is stated in the test certificate and stamped
into the discharge flange of the pump.
