Flow rate (at atm. pressure)
Robust, Durable and ATEX-Compliant
KNF N 630 Ex is the ATEX-compliant, explosion-proof series of its lineup. The series offers a selection of pump head configurations and connection types. Sporting robust performance with excellent gas tightness and chemical resistance, it is durable even in harsh conditions.
The affixed base rails and shock mounts efficiently reduce the noise and vibration during operation for N 630 Ex. Additionally, its flame-proof motor comes with a terminal box, further enhancing the overall safety and making the installation easier.
The N 630 Ex fulfills the criteria for completed machinery according to directive 2006/42/EC and therefore comes with the CE mark.
