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.

Concept

The emission measurement pumps from KNF are based on a simple principle ñ an elastic diaphragm, fixed on its edge, moves up and down its central point by means of an eccentric. Thus, the medium is transferred via automatic valves.

The new range of KNF pumps for the first time is equipped with the patented stress-optimized structured diaphragm, resulting in a durable product of high pneumatic performance. Special valves ensure minimum resistance to low.

Pumps and pump drives in this product series are explosion proof according to 2014/34/eu (ateX) and iecex. the high gas-tightness of the diaphragm system is especially important for use in potentially explosive atmospheres.

Feature

*Uncontaminated low (No contamination of the media due to oil-free operation)

*Chemically resistant (Against aggressive and corrosive gases and vapors)

*Maintenance-free

*Explosion proof versions to ATEX/IECEx

*High level of gas tightness

*Minimized pneumatic loss

*Long product life

*Ready for assembly

Can be operated in any installed position

Areas of use

The diaphragm vacuum pumps offer a high level of performance, as well as an excellent price performance ratio. They are required especially in the potentially explosive ields of chemical, analysis, energy and production technology.

The pumps are used for transferring, compressing and sucking air, gases and vapors, taking samples (even liquids in a vacuum) and evacuating and compressing vessels etc.

Beside other applications, pumps are used for gas measurement, for example for sampling gases out of the ambient environment, or for exhaust gas and smoke analysis. Easy installation and adaption to a variety of processes.
