B25 Metallic Pump
Blagdon B25 Metallic AODD Pump
The Blagdon B25 Metallic air-operated double diaphragm (AODD) pump is designed for reliable transfer of chemicals, process fluids and demanding industrial liquids where durable metallic construction and dependable operation are required.
With a maximum delivery of up to 180 litres per minute (48 gal/min) and working pressure up to 8.6 bar (125 PSI), the B25 provides dependable fluid transfer while handling suspended particles up to 3 mm.
Available in aluminium, cast iron and stainless steel configurations, the B25 provides material options for a wide range of process applications. Its self-priming design, bolted construction and end-ported configuration support reliable operation, while weighted valve balls can assist with high specific gravity and viscous fluids.
