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.

OPERATING

 

DATA 

 
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.
