How getting things right to begin with and carrying out a basic maintenance regime on submersible pumps, reduces down time and productivity losses.

 
Feature
 

Dry running leads to a surge in pressure, flow or overheating that will instigate a pump failure. As a result, the pumping elements seize up on the shaft.
