The Blagdon B25 High Pressure air-operated double diaphragm (AODD) pump is designed for demanding 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 125 litres per minute (33 gal/min) and working pressure up to 16 bar (232 PSI), the B25 High Pressure provides dependable transfer performance while handling suspended particles up to 3 mm.
Its robust bolted construction, smooth pumping action and reliable pneumatic air valve support dependable industrial operation. The pump can stall safely against a closed discharge head without damage and restart automatically when demand resumes.
