Hydraflo™ H3NC High-Head Non-Clog Pump

High-Head Hydraulically Non-Clog Submersible Pump

The Hydraflo™ H3NC high-head non-clog hydraulic submersible pump is designed for use in the toughest environments. These non-clog pumps never quit—helping to improve your bottom line.

Available for Rent

While typical Waste Water Treatment Plant bypass operations require eight water pumps to handle the primary flow and 1-2 extra pumps with only 25% redundancy, just four H3NC 24″ pumps can handle the full plant bypass with 100% redundancy*. 

MWI developed the Hydraflo™ H3NC non-clog pump as a simpler, more robust solution. These hydraulic submersible pumps outperform other bypass pump systems and lift stations with their efficiency, cost-effectiveness, and space-saving design. Available with electric or diesel drives, one H3NC 24” system with four pumps and drive units uses 50% less space than traditional bypass pump systems. The Hydraflo™ non-clog pump also has a 200% larger handling capacity for solids up to 6” and a flow of 25MGD per pump.

Additionally, the entire H3NC system can be installed in half the time of a typical plant bypass and is expertly maintained by our servicemen during the length of your pump rental. To get the job done right, choose the security and efficiency of the H3NC non-clog pump to handle your full plant bypass operation with 100% redundancy.

  • Hydraflo™ non-clog pumps easily handle solids 200% larger than traditional centrifugal pumps, and up to 6” spherical solids
  • High efficiency & performance – with up to 90’ TDH and 18000 GPM / 25MGD per pump
  • Small footprint – total system takes up to 50% less space than conventional bypass pump systems
  • Low-upfront & operational costs – up to 40% less energy consumed*
  • Unique pump developed by MWI for the toughest pumping jobs
  • Full sewage treatment plant bypass with 100% redundancy by using only four H3NC 24” pumps
  • Reliable – runs dry indefinitely with oil-lubricated seals and bearings
  • Closed two-bladed impeller handles trash and sewage with ease
  • Available in electric or diesel drives
  • Install in half the time of a traditional bypass system
* As compared against standard skid mounted end suction centrifugal pumps operating at maximum lift and a flow of 55,000GPM
