Blagdon B75 Non-Metallic AODD Pump for high-capacity chemical and industrial fluid transfer applications

Blagdon B75 Non-Metallic AODD Pump

The Blagdon B75 Non-Metallic air-operated double diaphragm (AODD) pump is designed for high-capacity transfer of corrosive chemicals, viscous fluids and demanding industrial process liquids where non-metallic wetted construction is required.

With a maximum delivery of up to 901 litres per minute (238 gal/min) and working pressure up to 7 bar (102 PSI), the B75 is suitable for large-volume fluid-transfer applications while handling suspended particles up to 18 mm.

Available in polypropylene and PVDF configurations, the B75 provides material options for applications involving aggressive or corrosive fluids. Its simple construction, adjustable flanged connections and proven pneumatic air valve support reliable operation and straightforward maintenance.
