Various domestic wells, smaller waterworks, or irrigation systems are systems where frequency drives are increasingly finding their use. They are a very good addition to pumps because they reduce energy consumption, allow their extended regulation and also contribute to the safety of the entire system. We will advise you on how to choose the right frequency drives for the pump.

The main task of the frequency drives in a system with a pump is to control the pumping system by regulating the pump speed and ensuring a constant pressure in the entire system. But for the whole system to work really efficiently and to make the most of your new frequency drives, you need to carefully consider its choice.

When selecting a frequency drives for a pump, all parameters of the specific system must be taken into account. Whether it is a well or an irrigation system, each has specific characteristics that need to be adapted as much as possible to the choice of frequency drives. But so that you can better imagine the questions when choosing, we have prepared an overview of parameters for you, which you should definitely not overlook.

1. We look at the internal factors of the pump

In this respect, you still have to follow the data from the pump manufacturer. Keep in mind, however, that they may not always be accurate, and there may be minor variations in a particular system. Therefore, take the power input, voltage (eg 230 V, 400 V or 3 x 230 V) and current load of the pump into account. Just be sure to allow for a certain margin when using the pump.

2. We are interested in the degree of load on the system

Find out how the system is loaded and also to what extent. How often the load in the system increases, how fast it occurs and also how long it lasts. In any case, most frequency drives can easily handle very fluctuating loads.

3. And last but not least, the resistance of the frequency drives itself

Think about where and under what conditions the frequency drives will be installed. In the case of outdoor installation, it is definitely worth preferring a frequency drives with increased resistance at least at the IP65 level, which is a guarantee of resistance to dust and splash water. Let’s add that a frequency drives from the category for outputs from 0.75 kW to 18.5 kW will certainly suffice for normal home use.
