Pump Performance - an overview | ScienceDirect Topics

7.1 Efficiency of pumps. Centrifugal pump performances are tested by using clean cold water or viscous oil. Pump efficiency is determined by principally two parameters, head and flow rate, in addition to other factors such as properties of the fluid, impeller design and motor speed selected.

Best Efficiency Point (BEP) by CENTRIFUGALPUMP.COM

The Best Efficiency Point (BEP) is an important parameter used in evaluating the hydraulic characteristic of centrifugal pumps and defines its operation. The BEP is an important parameter because it is used to set limits to the pump operation. 1. It is typical to cutoff or stop the end-of-curve at 120% to 130% of BEP - …

Lecture 25: ,Centrifugal pump,: characterisitcs, ,efficiency,, NPSH ,Centrifugal pump, The fluid turbo machinery essentially consists of an impeller rotating in a casing. Fluid enters the eye of the impeller (the center of the impellers) and exits though the space between the impeller blades to the space between the impeller and casing walls.

How To Read A Centrifugal Pump Curve
How To Read A Centrifugal Pump Curve

Pump efficiency numbers of 60-80% are normal. 8. MINIMUM FLOW. A centrifugal pump requires a minimum amount of flow to be moving through the pump to dissipate the heat created. On the left side of the curve, minimum flow is indicated by a vertical bold line; operation to the left of this line is not recommended and can significantly decrease the life of the pump. Knowing how to read a centrifugal …
