The Blagdon X75 Metallic Flap Valve air-operated double diaphragm (AODD) pump is designed for high-capacity transfer of sludge, slurry and heavily solids-laden industrial fluids where large particles must pass through the pump reliably.
With a maximum delivery of up to 998 litres per minute (264 gal/min) and working pressure up to 8.6 bar (125 PSI), the X75 provides high-volume transfer while handling solids up to 75 mm (3″).
Its flap-valve system and bottom-discharge configuration help large solids move through the pump efficiently while reducing the risk of material settling inside the pumping chamber. Robust bolted construction and a serviceable pneumatic air valve support dependable operation in demanding industrial applications.
