NOTE: Before dismantling the pump make sure that it has stopped. Empty the pump of liquid 
before it is dismantled from the piping system. If the pump has been pumping dangerous 
liquids you are to be aware of this and take the necessary safety measures. 

If the pump has been pumping hot liquids, take great care that it is drained before it is removed 

from the piping system. 

 

NOTE: All maintenance, service and installation work can be carried out by Speck Pumpen or 
authorized workshops. Contact our sales staff to discuss your requirement. 

 

NOTE: After a prolonged period of operation the individual components may be hard to pull off 
the shaft. If this is the case, use a brand name penetrating agnet and/or 

– if possible – an 

appropriate puller. 

Preparing the pump set 

1.  De-energise the pump set and secureit against unintentional start-up.

 

2.  Reduce pressure in the piping by opening a consumer installation. 

3.  Disconnect and remove all auxiliary pipework. 

Draining the pump 

When the piping system has been drained, note that there is still liquid in the pump. Remove the 

liquid by dismantling the pipe plug (3) at the bottom of the pump.  

Dismounting the complete pump set 

 

NOTE:  The pump casing can remain installed in the piping for further dismantling. 

The notes and steps stated in have been observed/carried out. 

1.  Disconnect the discharge and suction nozzle from the piping. 

2.  Depending on the pump/motor size, unscrew the bolts that fix the support foot and/or motor 

foot to the foundation. 

3.  Remove the complete pump set from the piping.
