Note that the average life for a component varies with the conditions of use. 

 

Always follow 4.1 Cautions for Operation, and remember that life is extended by running the 
pump at minimal load (running the pump at minimal load is operation at the achieved pressure 
(inlet closed)). 

 

Bearings are replaced by the manufacturer’s service division.
