XDP pump

Xtreme Duty Pro™ XDP

The Xtreme Duty Pro™ XDP is designed for use in process type applications including filter press, high pressure, extended deadheading, long runs of discharge pipe and where air consumption is critical. Air power is conserved by actuating the air valve using a mechanical linkage instead of relying on air pressure. Air power is reduced by 20% vs a standard air-actuated valve providing more pressure to drive the diaphragm assembly.

Available in 1-1/2″, 2″ and 3″ port sizes, these pumps are built on the liquid platform of a standard NDP-serie pump, but with the world’s only mechanically-actuated air motor. Xtreme Duty Pro™ XDP pumps are capable of running on air pressure equivalents as high as 9 Bar or as low as 0,4 Bar and provide the same liquid side performance as the NDP-serie pumps.
