Diaphragm Pumps

The NMP 820 is an efficient flow-to-size, light weight addition to the KNF line of micro diaphragm gas pumps. Single- and two-head versions are available, producing 17.4 psig (1.2 barg) final pressure. Flow rates and ultimate vacuum for the single-head versions are up to 2.1 l/min and to 330 mbar abs (20.2 in. Hg), respectively. Two-head versions offer flow rates up to 3.5 l/min and ulti...
