XDP-80 series pumps

the Yamada? 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.

Available in 1-1/2", 2" and 3" port sizes, XDP pumps are built on the liquid platform of a standard (pneumatically-actuated) NDP Series pump, but with a mechanically-actuated air motor. Air power is conserved by actuating the air valve using a mechanical linkage instead of relying on air pressure. Air power is reduced versus a standard air-actuated valve, providing higher pump efficiency.

XDP pumps are capable of running on air pressure equivalents as high as 125 PSI or as low as 5 PSI and provide the same liquid side performance as the NDP series pumps.
