FAQ

We are happy to help you find the right pump for your project. To do this, we need as much information as possible about the type of work the pump will perform:

• How much water should the pump be able to pump, and within what time frame?
• How high should the water be pumped and how far along the ground?
• Do you already have piping? If so, what is its diameter? If not, we will determine the appropriate piping.
• Tell us as much as possible about the liquid that needs to be pumped: Is it clean or polluted water? Does it contain chemicals? Does it contain solids, and what size?
• How will the pump be powered (electricity, diesel, ...)?

The pump curve is a curve that visually represents the performance of a pump.

The horizontal axis shows the flow rate (in m³/h), and the vertical axis shows the pump head (in m). The right end of the curve is the maximum flow rate of the pump, and the left end is the maximum head (above which no more water flows from the pump).

To check the flow rate at a certain head (8 m in the example), start from the vertical axis and go to the right until you touch the curve line. Then go down until you reach the horizontal axis and see the corresponding flow (6 m³/h).

It is best to use the pump in the middle third of the curve (the green part).

Some graphs have multiple curves, depending on the speed of the motor (rpm). It is important to look at the correct curve.
