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 bypass operations require 3 water pumps to handle the primary flow and an extra pump with only 33% redundancy, MWI developed the Hydraflo™ as a simpler, more robust solution. These hydraulic submersible pumps outperform other bypass pump systems with their efficiency, cost-effectiveness, and space-saving design. Available with electric or diesel drives, one HNC 20” system with two 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 20MGD thanks to its 200 HP engine.

To get the job done right, choose the security and efficiency of two HNC 20” pumps to handle your full plant bypass operation with 100% redundancy.

  • Easily handles solids 200% larger than traditional centrifugal pumps, and up to 6” spherical solids
  • High efficiency & performance – with up to 90’ TDH and 18000 GPM
  • Small footprint – total system takes up to 50% less space than conventional by-pass pump systems
  • Low-upfront & operational costs – up to 40% less energy consumed*
  • Unique pump developed by MWI for the toughest pumping jobs
  • Full sewage plant by-pass with 100% redundancy by using only two HNC 20” 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
* as compared against standard skid mounted end suction centrifugal pumps operating at maximum lift
