Construction and Materials

The BIOCOR series is available in three pump sizes B20, B32 and B40. The material for the wetted housing parts is electropolished SS 316 L (Basel Standard II, ferrite content < 1%) with a surface roughness of ≤ 0.4 μm (15.75 μin). The frame is made of 1.4404 and the center block of polyethylene conductive. The suction and discharge ports are suitable for Tri-Clamp or different sanitary threads (Naue, Neumo, DIN 11851, DIN 11864).

The diaphragms, ball valves and O-rings are made of PTFE or EPDM (FDA); other materials on request.
