WebNPSH r (Net Positive Suction Head Required) values typically range in only a few feet, thus enabling the handling of gas and low density applications. Positive Displacement Pump Examples Examples of the best PD pump include piston and plunger, diaphragm, gear, lobe, screw, and vane. Piston and Plunger Pump Courtesy: Wikipedia WebAxial-flow pumps, in addition to providing high anti-cavitation properties, must have high anti-erosion properties to ensure the required lifetime of the pump. Erosion damage of surfaces occurs when the net positive suction head (NPSH) significantly exceeds its critical value. The object of the study in this article is the axial-flow pump with a specific speed of … log in into teams
