Mounting Instructions MPE 

 
 

 

Rotate shaft (24) to see that it runs smoothly. 

 

The pump must be turned around for further assembly work (free shaft pointing upwards vertically)  

 

Assembly as for dismantling the pump. 

 

Lubricate shaft (24) 

 

Check position of the impeller: Insert end diffuser (2/E), slide impeller (1) until impact. 

 

The impeller is in the correct position when the impeller outlet channel lies within the diffuser intake 
channel. 

 

Avoid  flow losses:  Corrections can be carried out by adding compensation disks or by turning off the 
impeller hub on the rear side. This check must be carried out at every stage. 

 

If a pump is assembled with new impellers, care must be taken that the first and last stage is always 
provided with an impeller with the full blade diameter. If only one impeller is available with the full blade 
diameter it must be used as the first stage. 

 

 

Please note that assembly work always starts with the final stage.

 

 

 

Remove impeller and diffuser once again, insert O-ring (OR2), re-insert end diffuser (2/E). 

 

Insert key (PF1 or PF2) for the impeller that is to be mounted. 

 

Mount impeller (1) As the O-ring (OR2) presses on the diffuser (2/E) the setting will not be correct at first. 

 

Grease intensely O-ring (OR1) with silicon grease and fit it on the stage casing (60). Do not twist O-ring. 

 

Place stage casing (60) on level and force down sharply. Hit with a plastic hammer until it impacts.  

 

Assemble pump down to the suction casing (3)  

 

Slide on sleeve (38), mount suction casing (3) with O-ring (OR1), take care that the nozzle positions are 
correct. 

 

Further assembly work depends on the type of the shaft seal. See chapter 2.3. 

 

Assemble the bearings according to chapter 2.1 or 2.2 (Dismantling and mounting of the Bearings). 

 

Important mounting tips: 

 

All faces, sealing against an O-Ring, shall not show any scratch. Pay special attention at the sliding of the 
impellers on the shaft. 

 

The impellers have to stand  axially with  an accuracy of  appr. 

±

0,5 mm in der center of the diffuser 

channel. 

 

Brush the front faces of the impeller hubs with a liquid sealant (f.e. Hermetic) to eliminate internal flow in 
the pump. 

 

Brush the front faces of the stage casings with a liquid sealant (protection against corrosion). 

 

Coat the threads of the tie roads (25) with  MoS2-compound and tighten the nuts (M1) with the fastening 
torque M. 

 

Tighten constant in more steps on opposite sides alternate the nuts. 

 
Fastening torque for cold water pumps (temp. to max. 80°C): 

Pump type   

 

 

MPE 100.x 

 

MPE 125.x 

Fastening torque M   (dry)   

  455 Nm 

 

  785 Nm 

Fastening torque M   (lubricated) 

  410 Nm 

 

  710 Nm 

The fastening torque specification  for the tie roads of  hot water pumps  are shown in the instruction and 
operation manual. 
 

 

Slide on the coupling with the thread on the shaft front face. Do not strike it! 

 

Check the smooth running before start-up.  Check the alignment of the coupling and fill the bearing 
brackets with oil. 

 

Start-up according the IOM.
