BIOCOR Series Pharmaceutical Pumps for Sterile Applications

Almatec® BIOCOR Series Air-Operated Double-Diaphragm (AODD) Pumps have been specifically designed for critical sterile applications within the pharmaceutical, biotech and food industries. BIOCOR Series pumps are EHEDG certified and conform to EC1935/2004, FDA, USP Class VI and ATEX requirements. The special design of the fluid path enables the CIP and SIP capability.

All of the housing parts on the BIOCOR Series pump contain no horizontal areas, a critical consideration for sterile applications. Available with a 1.4435/316L polished stainless-steel wetted path, BIOCOR Series pumps provide superior containment and utilize four ball-lifting magnets that can be attached to the pump housing from the outside at the location of the four ball valves (available for B20 and B32 models only). With the use of magnets, the ball valves can be lifted from their seats, allowing the pump to be drained entirely without needing to be disassembled or removed from the application.

In Compliance with Hygienics Standards

Aseptic pumps of the BIOCOR Series are built in compliance with the corresponding hygienics standards (EHEDG, FDA, Class VI, etc.). The special design with the integrated cleaning-system enables clean-in-place (CIP) and SIP sanitize-in-place (SIP) capability. In addition, the pumps are conform to ATEX. For the EHEDG confirmation every BIOCOR pump is equipped with a diaphragm sensor (code D1).
