Leak-Tight Gas Pumps from KNF

13 August 2019

KNF has released a series of double diaphragm, oil-free pumps that are designed for the safe transport and evacuation of costly, high purity, rare and dangerous gases.

With a patented double diaphragm system, the primary diaphragm does the pumping, while the safety back-up diaphragm keeps gas from escaping during failures. In addition, the pump is designed to prevent contamination from external sources. Options including active inter-diaphragm leak monitoring, material and motor choices, and multiple levels of leak testing are available. These pumps are ideal for chemical, nuclear or process engineering applications, including gas sampling and monitoring as well as pulse tube and dilution refrigeration.
