Dangers with positive displacement pumps
Web1. Pump Selection. The best way to prevent cavitation is to choose the correct pump for the application. Cavitation increases as the pump head (NPSH) falls or as capacity raises. so selecting the right pump to maintain a positive margin between NPSH available and NPSH required is the first move towards cavitation prevention. WebJul 1, 2024 · 1. It creates high pressures from low-flow situations. A reciprocating pump draws fluid or gas into its chamber through a small opening. It then releases that fluid or gas when the liquid or gas is …
