Home / Products / Pumps / Moyno / 2000 HS System


The 2000 HS System combines high pump efficiency with low discharge pressure to provide unmatched performance in high solids sludge cake transfer. Compared to hydraulically driven, piston ram type pumps and open conveyors, the 2000 HS System requires a much lower capital investment, lower operating costs and less maintenance.


    High-viscosity and high-solids

    fluid supply

    • Via suction hopper of Twin Screw Feeder (TSF) and chutes
    • Capable of varying TSF length to match wide feed areas from centrifuges and 1 through 2-meter length belt filter presses


    • Municipal sludge from 15% to over 50% solids
    • Non-flowable products
    • Calcium Carbonate
    • Magnesium Hydroxide paste
    • Cellulose fiber
    • Spent grain
    • Battery paste

    Twin Screw Feeder


      • Capable of varying auger sizes without changing pump arrangement to match the width of the TSF opening to the drop zone
      • Concentric rotation in a close tolerance pressure tube allows the TSF to generate positive stuffing pressure to the pump inlet (normally between 10 to 30 PSI at the pump inlet)
      • Dual augers counter-rotate to create a pull-down effect with the product
      • Intermeshing augers provide self-cleaning action so the product will not stick to the augers and fill in the flights
      • Sidewalls are completely vertical into the augers, which does not allow the product to bridge
      • Close tolerance to sidewalls eliminates product ledge where bridging can gain a foothold
      • TSF can be run at separate RPM from the pump, allowing control over the amount of stuffing pressure

      g4 pump


      • Universal joint is out of flow path for unobstructed flow to pump cavity inlet
      • Wide sweep pump inlet to lower friction loss
      • Patented auger feed on rotor head stuffs product directly into the cavity without obstruction
