High Efficiency Pumps

Different pumps offer different efficiencies depending on the application. It is therefore important to select the pump that is best suited for the application in question.
It needs to be remembered, however, that pump efficiency can drop during normal operation by as much as 10 - 25%. 50 – 60% lower efficiencies are common.
