Centrifugal Pump curves show 8 important factors that are critical inselecting the right pumpfor your application. These factors are: Flow, Head, Impeller Trim Diameter, Efficiency, Power, NPSHR, MCSF (Minimum Continuous Stable Flow) and RPM. The Pump curve also displays the Pump model, the Pu...
The curve will show you if the pump you have selected will perform in that application.1. HOW TO READ A CENTRIFUGAL PUMP PERFORMANCE CURVE? Curves typically include performance metrics based on pressure, flow, horsepower, impeller trim, and Net Positive Suction Head Required (NPSHr). Centrifugal...
One of the same scientific principles that helps us to explain how centrifugal pumps function may also help us to understand how aeroplanes fly. Consultant Joe Askew explores these concepts and looks at how they apply to our pumps, planes and some other common devices that we see in our ...
It’s very frustrating to have your ship role over and sink as soon as it begins to take on water, or to spend the day sitting at the side of the pond working on your ship instead of participating in the game. Consider a used ship as your first ship. This will allow you to begin...
How to calculate motor efficiency for variable-speed centrifugal pumps: knowing the efficiencies of the pump, VSD, and motor will enable the engineer to calculate the kW input for a pump, from minimum to maximum flow and head conditions for that pump. Here, the author goes through that ...
