The EHEDG (European Hygienic Engineering & Design Group) certificate is your guarantee that the design is according to the hygienic guidelines. Furthermore, the pump is cleanability tested, which means bacteria does not grow in the pump after the cleaning and draining procedure. 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 also enabling accurate and precise control of the pump’s performance, optimising your system to the best of its ability!

The Aseptic Diaphragm Pump is also designed for cleaning and sterilisation in place – C.I.P. and S.I.P. After such operations, the pump is easily turned in its stand for drainage. Models are supplied with an extra fine surface finish to Ra 0.8 as standard and to Ra 0.5 upon request.

The pumps are supplied as standard with ISO Tri-Clamp connections, however, they may also be equipped with almost any type of connection used in the hygienic field – DIN clamps, SMS milk, RJT, DIN aseptic to mention a few.

Thanks to Tapflo’s innovative, simple & ingenious design these pumps are compact, robust & reliable. Furthermore, they are quick & easy to maintain, keeping your service costs and process down time to an absolute minimum.
