New design of Multisafe Double Hose-Diaphragm Process Pump provides longer service life of wear parts, lower maintenance costs and easy cleaning features. Pump is double sealed from the environment, if one hose- diaphragms fail, the second one ensures that the pumped fluid will neither come into contact with the pump casing nor with the hydraulic chamber. The constant displacement-controlled movement of the elastomere material ensures an extraordinarily long service life of the hose- diaphragms.
