The Blagdon B50 High Pressure air-operated double diaphragm (AODD) pump is designed for demanding industrial fluid-transfer applications requiring higher discharge pressure, including viscous liquids, high specific gravity fluids and high-head duties.
With a maximum delivery of up to 350 litres per minute (92 gal/min) and working pressure up to 16 bar (232 PSI), the B50 High Pressure provides dependable high-pressure fluid transfer while handling suspended particles up to 6 mm.
Its robust bolted construction, smooth pumping action and reliable pneumatic air valve support dependable operation with reduced vibration and wear. The pump can safely stall against a closed discharge head without damage and restart automatically when demand resumes.
