Aseptic Diaphragm Pump (EHEDG)

Our Aseptic Diaphragm Pump is cleanability tested, meaning bacteria does not grow in the pump after cleaning and draining. Units can also be delivered with backup diaphragm systems. There are no hidden areas where bacteria can grow. The manifold clamps and the housing screws are simply removed for complete disassembly and cleaning.

When used in conjunction with Tapflo’s patented control and monitoring equipment, preventive and routine maintenance is also easily integrated into any process whilst enabling accurate and precise control of the pump’s performance, optimising your system to the best of its ability!
