The system head visualized in the System Curve above is a function of elevation - or the static head and themajor and minor lossesin the system and can be expressed as: h = dh + hl(1) where h= systemhead(m) dh=h2- h1= elevation (static) head difference between the inlet and outle...
say 1 and 2, depends on the shape of the system curve (see next Figure). The points that lie on system curve A will all be approximately at the same efficiency. Whereas the points that lie on
A pump performance curve chart is a valuable tool for selecting and operating a pump in a specific application, providing the data for optimal pump and system efficiency and performance. It should be noted that pump curves will differ between different pump types as they have different internal ...

9.3.12.4The purchaser shall specify whether sump-pump services for VS4 and VS5 pumps are open-system or closed-system arrangements. For closed-system arrangements with pressure-containing vessels or tanks, the purchaser shall specify the maximum pressure in the vessel or tank as the maximum suctio...
Torque vs. Speed Curve for Centrifugal Pumps A pump’s torque-speed curve is used to determine the appropriate motor to match with it. A pump’s torque-speed curve is produced by plotting the percentage of full load torque (FLT) vertically against the percentage of full load speed (FLS) ...
The performance curve will be different for each pump and some will suit our system needs better than others. You will usually see that as the flow rate increases, the head pressure decreases. When selecting a circulating pump, the pump will only perform as per the line. So, if you need...
