Understanding Pump Performance Charts

Furll article and practical examples available at our blog

Have you ever found yourself in a situation where selecting the right pump becomes a nightmare? All you need is the pump that suits your application, so you start browsing around, but now you are faced with too many choices and charts that confuse you and won’t allow you to make a final decision. Not to worry, we are here to help!

This article is all about assisting you in understanding pump charts and their importance when choosing the right pump for your application:

• Pump size

• Pump performance

• Pump capacity

o Suction lift

o Fluid viscosity

Pump Size:

First of all, let’s take a look at the pump size. This step is crucial to determine how big or small a pump needs to be, to meet your application´s needs. The desired flow rate and discharge pressure required can be achieved for many applications with different pump sizes.

Always choose your pump size considering your flow rate and discharge pressure. Selecting the right pump size will result in high-quality performance with a reduced air consumption and a longer pump life.

Pump Performance:

Now that you understand why the pump size is important, let’s take a look at the second chart you should be analyzing and why: The pump performance chart. This useful chart provides data regarding how a particular pump performs under certain conditions.

Pump Capacity

The pump’s effective capacity is determined by two factors: suction lift and fluid viscosity.

Suction Lift:

The first aspect to take into consideration is the SUCTION LIFT because pump effective capacity decreases when the suction lift increases.

Fluid Viscosity:

Viscosity is also a fundamental aspect when selecting a pump because it determines the fluid´s resistance to flow. This aspect is crucial because pump effective capacity decreases when the fluid viscosity increases.
