The Blagdon B50 Non-Metallic air-operated double diaphragm (AODD) pump is designed for high-capacity transfer of chemicals, viscous fluids and other demanding process liquids where corrosion-resistant non-metallic construction is required.
With a maximum delivery of up to 530 litres per minute (140 gal/min) and working pressure up to 8.6 bar (125 PSI), the B50 is suitable for applications requiring high flow rates while handling suspended particles up to 6 mm.
Available in polypropylene and PVDF configurations with aluminium or stainless steel options, the B50 offers material flexibility for a wide range of industrial fluid-transfer duties. Its simple construction, proven pneumatic air valve and robust design support reliable operation and straightforward maintenance.
