Air operated diaphragm pumps
Introduction Plastic Pumps Metal Pumps Sanitary Pumps Special Applications
The Tapflo sanitary series is particularly 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 some of the major features for this pump series.
Made to be clean: The pump 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 simply removed for complete disassembly and cleaning. The pump is also designed for cleaning and sterilization in place – C.I.P. and S.I.P. After such operations, the pump is easily turned in its support for drainage.
ATEX certified pumps: All sanitary pumps are available in explosion proof ATEX marked version. They are supplied with earth connection and conductive materials; conductive centre section and diaphragms in PTFE (conductive back) or EPDM (conductive).
1. Quick dismantling:
The clamp system ensures rapid dismantling without any tools.
2. Plain surface: The sandwich diaphragm has a completely plain surface, which eliminates bacteria growth problems. The diaphragm is available in food grade materials – PTFE or white EPDM.
3. Superior finish: Both liquid side and outside is electropolished, to obtain superior finish and hygiene. Special surface finish may be done accordning to your requirements.
4. Pollution free air valve: The sealing system is lubrication free, always keeping your product and environment free from oil contamination.
