Diaphragm Gas Pumps and Compressors

Sampling, evacuating and compressing – for tasks like these, KNF offers a wide range of diaphragm pumps and model variants. All the pump types offer media transfer without contamination and are maintenance-free.

 
Model Flow rate at 
atm. pressure 
(l/min)		 Vacuum
(mbar absolute)		 Pressure 
(bar g)		  
Explosion proof pumps up to 220 down to 53 up to 4.0
Temperature-resistant and heated pumps up to 100 down to 180 up to 1.5
Chemically resistant pumps up to 60 down to 2.0 up to 1.5
Double diaphragm pumps up to 280 down to 4 up to 3.0

 

Explosion proof pumps

Explosion-proof pumps are designed to prevent internal or external explosions by enclosing parts that could ignite either the transfer media or the surrounding atmosphere. KNF supplies a range of explosion-proof pumps for use in potentially explosive atmospheres. All our pumps are ATEX-compliant and certified in accordance with the 94/9/EC directive on equipment and protective systems.

Temperature-resistant and heated pumps

Temperature-resistant pumps can transfer air as well as neutral or aggressive gases at temperatures up to 240 °C. In order to prevent condensation of the measuring gas, the heated head pump types possess temperature-resistant pump head components and optional thermostatic or electronic temperature control.

Double diaphragm pumps

KNF double diaphragm pumps offer a high level of performance and greatly enhance safety, especially when working with dangerous, rare and valuable gases. A second diaphragm is located underneath the working diaphragm. The safety diaphragm has a significantly longer service life than the working diaphragm, thus ensuring that no gas can escape into the environment even if the working diaphragm ruptures.
