Study on the H-Q Characteristic Curves of Centrifugal Pump ...

Aug 19, 2015 Based on the basic energy equation and the loss calculation model of centrifugal pump, the formation of centrifugal pump H-Q curves with the inlet pre-whirl is analyzed. The analysis shows that pre-whirl angles is very important to the B which is slope of the real centrifugal pump theoretical HT-Q curve, and the influence of the B and the C which is the …

Aug 30, 2021 Pump engineers are familiar with the performance curve of a centrifugal pump. For a fixed speed, the head varies with flow and the performance envelope can be clearly defined, although this envelope is often ignored to the detriment of reliability (Image 1). Engineers intuitively use the mental image of the pump performance curve to evaluate the operating …

How to Read a Pump Curve: Complete Guide

How to Read a Pump Curve: Complete Guide

Jan 03, 2022 Fig. 2. A basic pump performance curve for centrifugal pumps show it's performance range. In this curve, head is measured in PSI; flow is measured in gallons per hour. Given the relationship between head and PSI, we can look at the sample curve in another way and say that at 184.8 feet of head (80 psi X 2.31 feet), the pump will generate a flow ...

Understanding Pump Curves Pumps Systems

Jun 27, 2016 In my last column (Tips for Proper Pump Selection, Pumps Systems, May 2016, read it here), I briefly mentioned drooping pump curves and stated that I would spend time in a future article discussing the subject. A drooping pump curve is a characteristic head-flow pump performance curve that does not continually rise when moving from the best …

Pump Curve for Centrifugal Pumps based on - API 610

Pump Curve for Centrifugal Pumps based on - API 610

Pump Curve for Centrifugal Pumps based on - API 610 Pump Curve BEP: A point on pump curve that flowrate at which a pump achieves its highest efficiency at rated impeller diameter. The best efficiency point flowrate at maximum impeller diameter is used to determine pump specific speed and suction specific speed.

Pump Curve for Centrifugal Pumps based on - API 610

Shutoff point shows the highest point on the pump curve (if pump has stable curve). The shutoff pressure of a typical centrifugal pump is approximately equal to the sum of the maximum suction pressure and 120% of the net differential pressure generated by the pump, based on the maximum anticipated fluid density.
