The Blagdon X50 Metallic Flap Valve air-operated double diaphragm (AODD) pump is designed for demanding transfer of slurry, abrasive fluids and solids-laden industrial liquids where larger particles need to pass through the pump.
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 X50 provides high-capacity fluid transfer while handling solids up to 50 mm (1.97″).
Its flap-valve configuration is suited to applications involving larger suspended solids that may be difficult for conventional ball-valve pumps. The X50 also features self-priming operation, bolted construction and a reliable pneumatic air valve system for dependable industrial service.
