What is NPSH?A letter to the editor is presented concerning the definition of Net Positive Suction Head published in the June 2006 issue.Gilmer, RonIntech
NPSH or Net Positive Suction Head is a very important part of a pumping system. The systems NPSHAmust be higher than the pump’s NPSHRin order for proper pump performance and to eliminate the risk of cavitation, which can damage a pump in short order and shut down operations that depend ...
Second, calculate the NPSH available (NPSHa). This value represents the absolute pressure available at the pump inlet. If the NPSHa is 3 feet more than the NPSHr, the pump will not cavitate. Be aware, NPSHr is measured under ideal conditions for repeatability and accurate benchm...
The best way to prevent pumps from experiencing cavitation is to increase the pressure upstream from the pump’s impeller. This pressure is known as the net positive suction head (NPSH). AnAnsys EnSightvisualization of oil volume in a gerotor pump shows the extent of cavitation (red) on the...

It can be run for a small phase. It has a huge and big footprint. The net positive suction head (NPSH) requirement is very low. Advantages and Disadvantages of Gear Pumps The advantages of these pumps include the following. Maintenance is simple ...
