Figure 34:  Parts for impeller of pump head CP-4.34/36

  

A-H: Parts of impeller exchange kit is IEK-4.10. 
a-d: Other parts of pump head.

 

The following warnings and cautions should be 
read carefully before starting the exchange of 
the impeller. 

 
 
 

 

 

WARNING

 

 

 

 

 

 

The impeller could splash toxic or corrosive chemicals 
because of the strong magnetic forces. Flush the 
pump housing before opening it.

 

 
 

 

 

WARNING

 

 

 

 

 

 

Harmful chemicals may be present. 

Skin contact and toxic gases may be hazardous to 
your health. Wear safety gloves and other appropriate 
safety equipment.

 

 
 
 
 

 

 

CAUTION

 

 

 

 

 

 

The rotating impeller could cause injury. Do not run the 
pump system when opening the pump head.

 

 
 

CAUTION 

 

 

 

 

 

Pay attention to the magnetic forces when handling the 
impeller. The attraction of magnetic parts and particles 
should be avoided in order to keep the impeller and the 
pump head clean and free of contamination.
