The KNFs, new N 630 diaphragm vacuum and compressor pump series provides durability with cost-efficiency and delivers on high pressure and gas tightness. Four versions are available for use in industrial coolant systems, gas recycling, gas and emissions measurement/analysis, and leak detection across a wide variety of industries, from chemical processing and energy to physics research. The company’s new N 630 diaphragm vacuum/compressor pump series with long service life, vacuum down to 0.74 inHg (25 mbar abs), positive pressure up to 174 psig (12 bar rel), and a flow rate up to 2.4 CFM (68 L/min), in the N 630 series offers – impressive, highly versatile performance. The cost-efficient and reliable diaphragm gas pumps are available in four variants: either one- or two-headed and connected in series or parallel, as a vacuum pump, or as a compressor. All models come with long-lasting EPDM or chemically resistant PTFE-coated diaphragms for exceptional durability and service life.
The N 630 series handles temperatures down to 41 °F (5 °C), and headwater cooling systems make them suitable for use at ambient temperatures up to 140 °F (60 °C). The N 630 pump series is particularly well-suited for applications in helium cooling, valuable gas recovery/recycling, measurement and transfer of explosive gases, and pressure boosting for biogas/natural gas engines. Other applications include emissions measurement and flue gas analysis, LNG QC, and gas leak detection.
