ASEPTIC EHEDG AIR OPERATED DOUBLE DIAPHRAGM PUMPS
The Tapflo Aseptic EHEDG Air Operated Double Diaphragm Pumps Series has been developed for service within the pharmaceutical, bio-tech and food industries where a clean process and ability to clean components quickly is critical. This series of pumps is EHEDG Certified and is constructed from FDA & USP VI approved materials and also conforms to ATEX directive 94/9/EC which means it is perfectly suited to almost any applications in the aforementioned markets.
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.
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. Models are supplied with an extra fine surface finish to Ra 0.8 as standard and to Ra 0.5 upon request.
