2019-2-4 Centrifugal Pump Characteristic Curve For an Operations Engineer who is working in a Chemical Process industry or a Process engineer who is involved in Hydraulic calculations understanding the Centrifugal Pump Performance Curve is an important aspect. Components of Centrifugal pump performance curve 1. Head Vs Flow Curve : H-Q Curve 2.

More2022-1-1 The characteristic curve of the centrifugal pump is determined by the design intention and actual test at a certain speed. The three characteristic curves of H-Q, η-Q and N-Q are measured by the pump manufacturer before leaving the factory, which is a

MoreThe pump head in layman’s language is nothing but the pressure produced by the pump and flow rate means the quantity of liquid flow per hour. Fig. 2 Pump characteristics curve axis. The pump head is denoted by H. Pump flow rate is denoted by Q.

MoreSystem Characteristic Curve. In the pumping system, there are two characteristic curves that determine the operating point of the pump. One is related to the pump itself, which is called the pump characteristic curve, and the other is related to the system and components before and after the pump, which is called the system characteristic curve.

More2017-7-5 Typical centrifugal pumps will show an increased flow rate as head pressure decreases. The curve also shows the shut off head or the head that the pump would generate if operating against a closed valve. In our same example, the shutoff for the 7.9” impeller is 45 ft of head. The pump performance curve also provides efficiency curves.
