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 2014/34/EU directive on equipment and protective systems.
