Diaphragm Pump - Air Operated

The Tapflo sanitary series is mainly designed to meet the requirements of the food, beverage, pharmaceutical and cosmetic industries. Lubrication free air distribution system, maintenance-free ball check valve system and total visual inspection of the wetted parts are significant features for this pump series.

Made to be clean

Our design allows for total visual inspection of the wetted parts. There are no hidden areas where bacteria can grow. The manifold clamps and the housing screws are removed for complete disassembly and cleaning. The 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 drainage support.

ATEX certified pumps

All sanitary pumps are available in explosion-proof ATEX marked versions. They are supplied with earth connection and conductive materials, conductive centre section and diaphragms in PTFE (conductive back) or EPDM (conductive).
