KNF’s N0150 diaphragm pumps can now be customized with water-cooled heads to prevent pump overheating in process applications where exothermic reactions from helium, xenon, and other gases may produce excessive heat and potentially shorten pump service life. They can serve industries ranging from specialty gases to radiopharmaceuticals, among others. The pump is designed to deliver the highest flowrate of any electrically operated diaphragm pump. The pump operates without oil to eliminate risk of medium contamination and can be equipped with a double-diaphragm system for increased safety critical when handling particularly dangerous gases. In addition to water-cooled heads, the process pumps can be customized with a variety of options to satisfy application requirements. Pumps can be supplied with explosion-proof motors for compliance with ATEX and Class 1 Division 1 Groups C and D hazardous locations; corrosion-resistant models can be developed to withstand harsh environments; specialized leak-tight capabilities can be enhanced; and a range of available pump materials can be specified to expand application potential. Depending on model, these pumps can achieve flowrates up to 300 L/min (10 SCFM), maximum vacuums up to 29.3 in. Hg, and maximum pressure up to 30 PSIG. They are designed to exhibit significantly low leak rates ranging from 6 x 10-3 mbar l/s (standard models) to 6 x 10-6 mbar l/s (double-diaphragm versions).
