Innovative brushless DC motor technology for KNF diaphragm pumps

With the new DCB-I drive, KNF is introducing an in-house developed BLDC motor generation for the first time in its history.

This new generation of brushless motors further increases the advantages of KNF diaphragm pumps to the next level in terms of performance, robustness, and durability in combination with the ability to digitally customise the motor parameters. By integrating the motor directly into the pump housing, it was thus possible to implement these features in a more compact size.

The development of our own BLDC motor allowed KNF to specify the individual components so that they are perfectly matched for their use in diaphragm pumps.

Compared to what is usual for other motors, the DCB-I features much larger ball bearings. This significantly improves the robustness and durability, which is reflected in a life expectancy of >20’000h. Furthermore, the unique design creates not only a visually appealing look, but also technical advantages. The cooling fins on the aluminium motor cover also improves heat management, especially when the motor is permanently under heavy load.

The development and manufacture of this new generation of motors is the outcome of a cooperation between KNF and a leading motor manufacturer.

As a result, not only is the motor more powerful (in relation to its size), but the development of its electronics makes it possible to use additional functionalities. As a result, this allows total control over the motor to fully exploit the potential of KNF pumps.

KNF offers the DCB-I for the following pump types:

Gas Pumps

• NMP830

• NMP830 HP

• NMP850

• NMP830 HP

Liquid Pumps

• NF30
