The aseptic air-operated diaphragm pumps were designed for sterile applications within the pharmaceutical industry. The pump’s characteristics include gentle product displacement, easy start-up, self-priming capabilities and a sterile design. The company has earned certification from the European Hygienic Engineering & Design Group (EHEDG) for their line of AOD pumps, as well as for conformity with ATEX’s 94/9/EG directive. The pumps earn this distinction by being constructed with a material combination of PTFE or EPDM (diaphragms, ball valves and O-rings). This design enables the pumps to be cleaned and sterilized in place. The pumps are equipped with PTFE configuration and a diaphragm-monitoring sensor that is 3-A approved. In meeting the demand for sterility in pharmaceutical applications, the liquid housings of pumps have no horizontal areas where the material being pumped can collect. Additionally, each pump comes with four magnets that can be used to easily move the stainless steel ball valves off their seats, which allow the pump to drain entirely without the need for disassembly. The pumps are available in two models, B20 and B32, that achieve maximum capacities of 15.4 to 33 gpm at a maximum discharge pressure of 7 bar. The material for the wetted housing parts is electro-polished 316L stainless steel. The center block is constructed of conductive polyethylene.
