Head Pump Curve at Mona Smith blog

Head Pump Curve. Learn about five types of centrifugal pump curves. The first piece of information provided by a pump curve is the flow that the pump will develop at any given operating head. At the maximum head (circled in red), the pump has zero flow or little. The performance of the pump at a certain speed (rpm) can be found in the manufacturer’s datasheet displayed as the flow rate (q) versus head curve (figure 2). In some instances our required flow rate and head pressure might fall between the two impeller diameter lines. Differential head, often referred to as “head” or “total dynamic head”, is a universal method of quantifying the pressure the pump is. For example 30 gmp (1.89 l/s) for a 4.5 inch (114.3mm) impeller gives us about 13 feet (3.96m) of head but if we used a 5.5 inch (139.7mm) impeller then we would get around 22.5 feet (6.89m) of head. Flow curve, efficiency curve, power curve, npshr curve & pump family curve. The pump performance curve describes the relation between the flowrate and the head for the actual pump. The curve begins at the point of zero flow, or shutoff head, and gradually descends until it reaches the pump runout point or maximum flow rate. The curve that provides this information is called the pump.
