These are AO/AB slurry pumps but with two bodies installed on the same shaft so that, working in series, high pressures can be obtained, particularly suitable for feeding filters for high pressing.

AO/AB/DC SERIES (DOUBLE STAGE VERSIONS)

  • Designed for slurries and/or acid applications.
  • The AO/AB/DC Series is the perfect solution for filter press feed or slurry transfer.
  • When pumping acid liquids, the shaft and the mechanical seal housing can be made of special alloys.
  • Capacities from 20 to 5000 gpm.
  • The maximum head for some Hardalloy versions is 500 ft.
