What do you need to know about a pump curve?

Also called a pump selection curve, pump efficiency curve, or pump performance curve, a pump curve chart gives you the information you need to determine a pump’s ability to produce flow under the conditions that affect pump performance. Reading pump curves accurately helps you choose the right pump based on application variables such as:

Which is the best pump for solids handling?

A lot of pump companies will give you marketing hype about their solids handling capabilities or performance, but Hidrostal Pumps are the real deal. Available in a variety of types and installations, Hidrostal has a solution for your need.

What should the impeller be on a pump curve?

The curve above shows impeller trim sizes, at the right end of each curve, ranging from a minimum of 4.33″ to a maximum of 6.42″. Reducing impeller size enables you to limit the pump to specific performance requirements.

When to use a series of centrifugal pumps?

Centrifugal pumps in series are used to overcome larger system head loss than one pump can handle alone. for two identical pumps in series the head will be twice the head of a single pump at the same flow rate – as indicated with point 2.

How is the Y axis of a pump curve measured?

The final portion of the pump curve is the power curve. Once again the x-axis is measured in units of flow, but the y-axis is now measured in power units. In this case the unit of measurement is horsepower, but in the case of an application measured in metric units, power is typically measured in kilowatts.

Which is the best software to read pump curves?

One of the most well-known developers of electronic pump catalogs is Engineered Software and their pump selection software pump-flo. Another popular option for pump selection software is Intelliquip. All of the curves in this article were generated by Pump-Flo’s web-based pump selection software.
