B50 Hygienic Pump
B50 Hygienic Pump
The B50 Hygienic Pump is a high-capacity air operated double diaphragm pump (AODD) designed for the sanitary transfer of viscous and sensitive fluids. Built with 316L stainless steel and FDA-compliant elastomers like EPDM and PTFE, the B50 delivers superior performance for large-scale food, beverage, dairy, pharmaceutical and chemical processing.
With a flow rate of up to 500 ltrs/min (132 gal/min) and 10 mm solid handling, this pump is ideal for operations requiring robust, hygienic and compliant fluid handling.
