Double diaphragm system for more safety in pumping toxic, hazardous or valuable gases.

Pump head heated to 240 °C. Prevents constituent parts of the media from condensing. Excellent heat isolation between pump head and surroundings. With electronic temperature control. The temperature can be adjusted from the control panel, which includes a display.

Structured diaphragm for vacuum pumps, with superior performance and a longer service life.
New valve system even tighter, quieter and with very low flow resistance; highly tolerant vapor and condensation.

Dynamic mass balancing for very smooth running roughing pumps.

Diaphragm stabilization System for vacuum pumps - optimized suction speed, especially for low absolute pressure.

Chemically-resistant diaphragm pumps for transferring highly aggressive gases in analytical technology and in laboratories.

Diaphragm pumps for potentially explosive areas (ATEX versions).

Vacuum pump system with remote control.

Automatic self-drying systems for use with vacuum drying and steam sterilization.


Metering pumps with step-motor drive and processor control: precise metering even for tiny amounts; with analog and digital interface ( portable version for Laboratory or in OEM version).

Overpressure relief integrated in the pump head, with bypass to the suction side.
KNF motors - the ideal drives for diaphragm pumps.
KNF modular system for optimal tailoring of pumps and systems to the customer's wishes.
