KNF’s N 630 series designed for coolant systems and gas recycling, measurement/analysis and leak detection.
KNF’s launched its N 630 diaphragm vacuum/compressor pump series in four versions for use in industrial coolant systems, gas recycling, gas and emissions measurement/analysis, and leak detection. The pump line can vacuum down to 0.74inHg (25mbar abs), positive pressure up to 174psig (12bar rel), and a flow rate up to 2.4CFM (68L/min). All models come with EPDM or PTFE-coated diaphragms and handles ambient and media temperatures down to 41°F (5°C); head water cooling systems make them suitable for use at temperatures up to 140°F (60°C). All N 630 pumps are equipped with IP55-rated motors designed to be operated via a variable frequency drive. The standard-model pumps are designed with a permanently attached base. combined with the rubber-bonded metal shock absorbers. The series fulfills the criteria for machinery directive 2006/42/EC and therefore comes with the CE marking.
