Securely Transferring Valuable, Rare or Toxic Gases

Add to card

Double diaphragm pumps from KNF are based on a simple principle: an elastic working membrane and safety membrane are held securely at their edges and moved up and down at their center by an eccentric. As a result, the working membrane moves the medium through automatic valves. The safety membrane has a significantly longer service life than the working diaphragm. The redundant arrangement of the diaphragms ensures that no gas can escape into the environment even if the working diaphragm ruptures.
