 Failure to comply with these instructions 

may cause damage and personal injury!

Transport and storage

Always protect the pump against ingress of water 

and other impurities. Store the pump in a clean, 

dry and warm environment. The pump is delivered 

with the internals oiled and with protective covers 

over the pipe connections and drain openings. 

These covers should remain in place for as long 

as possible during the mounting and installation 

procedure but must be removed before start up.

  

!

 All work carried out on the pump has to 

be performed in such a manner that risks 

for personal injury are observed! 

Lifting of pump

  

!

 All pumps should be lifted with straps 

securely attached to the pump or pump 

unit, so that the center of gravity is 

located between the straps in order to 

avoid tipping of the pump.

Use two eye bolts (M 20) securely fastened to the 

front cover for pump LPQ. Pump and connecting 

frame are lifted together using two eye bolts 

securely fastened to the top of the connecting frame. 

(Thread dimension is M 16, except for frame size 

600, where it is M 20).
