Pump Protection to Keep Industrial Wastewater Processes Flowing

3-HYDRO open channel, dual-shafted grinders reduce industrial wastewater solids into small particles using low-speed and high-torque grinding action. This industrial grinder is highly effective at reducing large wastewater solids that can otherwise damage, clog and foul downstream equipment, including pumps, valves, centrifuges and heat exchangers.

Its extensive range of cutting chamber lengths makes the 3-HYDRO a versatile workhorse capable of handling low and high-flow rate applications alike. This makes the 3-HYDRO open-channel grinder the ideal solution for maximizing process efficiency and minimizing equipment downtime. Additionally, the 3-HYDRO’s robust solids handling facilitates improved solids recovery and dewatering.

Typical applications include:

  • Drill cuttings
  • Oil sands processing
  • Petroleum processing
  • Pulp and paper mills
  • Chemical plants
  • Fish/beef/poultry processing
  • Manure
  • Recycling plants
3-Hydro C Site


  • Prevents unplanned equipment maintenance and process downtime
  • Protects pumps, valves, centrifuges and other downstream equipment from damage and clogs requiring costly repairs
  • Preconditions sludges, slurries and waste materials for improved solids recovery and dewatering


  • Dual-shafted, low-speed, high-torque grinder easily shreds the toughest solids, including rocks, wood, plastic, animal waste, plant waste and other debris
  • Compact footprint allows installation within most wastewater channels
  • Smart controller with load sensing control system optimizes performance and protects against jams
  • Custom frames for easy channel installation
  • Available Wipes Ready® Technology shreds fibrous, sinewy and stringy solids bi-directionally into small pieces preventing materials from reweaving in the waste stream to form long strips
  • Hardened steel cutters resist corrosion and wear
  • Various cutter configurations and materials are available to optimize the grinder performance by specific application
  • Global motor and controller options meet local energy efficiency and regulatory requirements
  • Immersible motors available to support application-specific operating conditions
