KNF Presents New NFB 100 Diaphragm Pump


KNF Flodos presents the new NFB 100, an OEM diaphragm pump featuring low pulsation and gentle transfer of liquids up to 2.6 l/min, as well as potential cost savings.

The NFB 100 has two pump heads driven by one motor, which creates real advantages. In parallel connected mode, the alternating operations of the pump heads result in a smooth and level flow. This reduces the need to install additional components to overcome pulsation. Operating in the individual mode, two different liquids can be transported at the same time, which can make a second pump superfluous. As a result, both modes offer cost-saving potential.

The pump’s compact design provides greater flexibility for customers when fitting it into their systems. Furthermore, the stroke volume of the pump is adjusted at KNF before the pump is shipped. Driven by an adjustable brushless DC motor, the pump s flow rate can be regulated by the customer and matched to its parameters. All this helps to reduce lengthy testing and improve time to market.

Using KNF Flodos’ well-proven diaphragm technology, the medium is transported very gently, which makes handling sensitive fluids easier. Furthermore, there is no pollution by abrasives, unlike, for example, with gear pumps. The handling of chemically aggressive fluids is enabled by using different materials for valves and diaphragms, in line with customer requirements. The result is a maintenance-free pump with a long service life that perfectly fits the intended purpose.
