N 630 Ex Explosion-proof Pump Series
Higher Performance, Extended Service Life, CE Marking
KNF developed its first Ex pump series in the 1970s, the N 143 Ex and N 186 Ex. Both have been replaced by the N 630 Ex series, which offers impressive performance and a range of useful features.
Features & Benefits
These are the main advantages of the N 630 Ex explosion-proof pump series:
- High chemical resistance
- Durable even with difficult operating conditions
- High level of gas tightness up to 5 x 10-5 mbar x l/s as a standard
- N 630.15 Ex version: High level of gas tightness up to 6 x 10-3 mbar x l/s as a standard
- Flameproof motor with intrinsically safe terminal box for simple installation
- Explosion protection three-phase motor: Ex II 2G Ex de IIC T4 Gb
- Explosion protection pump parts: Ex II 2G Ex h IIB+H2 T3 Gb
The Right Fit for Your Need
The N 630 Ex is available with either one or two heads and a serial or parallel connecting system as a vacuum pump or compressor. All four versions are outfitted with PTFE-coated diaphragms as standard, while EPDM is also available.

Modular System Options
Every application is different and some are one of a kind. By selecting and combining a variety of options, ranging from the material used to make the pump components that come into contact with the media, to the drive and the mechanical elements such as the circuit point and connections, it is easy to tailor every series model to meet application-specific requirements.
The following pump parts of the N 630 Ex explosion-proof pump series can be customized by our modular system:
▪ PTFE-coated
▪ Three-phase motor with 200/346 V, 50/60 Hz
▪ Three-phase motor with 220/380 V, 60 Hz
▪ Three-phase motor with 277/480 V, 60 Hz
