Permeate Pump

The permeate pump is non-electrical, energy-saving device which dramatically improves reverse osmosis system efficiency.

The Permeate uses only the hydraulic energy of the brine water to push additional purified water into your pressure tank. This increased pressure allows the reverse osmosis membrane to perform as if within an atmospheric tank system. Use of a Permeate Pump improves membrane life and system performance.

A Hague H3500 RO System with a permeate pump maintains full pressure across the reverse osmosis membrane, even as tank pressure reaches up to 95% of line pressure. This insures maximum TDS reduction both better water quality and extended membrane life.

The Permeate Pump will reduce the amount of wastewater produced by the reverse osmosis process by up to 80%. You can’t match the taste the pure water that only a reverse osmosis system can produce but we also value our natural resources and continually pursue ways to preserve them.


  • No electricity required, powered only by hydraulic energy.
  • Improves water quality by insuring membrane efficiency
  • Improves membrane life
  • Decreases product tank fill time by up to 65%
  • Reduces drain wastewater by up to 80%

Every Hague H3500 Reverse Osmosis unit receives a complete systems testing prior to leaving the factory.
