How to select centrifugal pump

Web4 jul. 2024 · Centrifugal pumps are suitable choices for clean and low-viscosity fluids. Generally, fluids with a viscosity of less than 500 Centistoke are the right choices. You can design a pump to transfer more viscous fluids, but that requires more power and is more inefficient. Fluid Vapor Pressure Very low vapor pressure may cause cavitation. WebThe steps to follow to select a centrifugal pump are: 1. Determine the flow rate. To size and select a centrifugal pump, first determine the flow rate. If you are a home owner, find out which of your uses for water is the biggest consumer. In many cases, this will be the bathtub which requires approximately 10 gpm (0.6 L/s).
