Hevvy Pumps, the global evolution of Toyo Pumps, introduces the HNS heavy-duty modular submersible pump series, available in 10HP-800HP.  The HNS range is redefining the submersible pump market by answering one of the most frequent causes of failure in the submersible pump world: mechanical seal failure.

Hevvy offers the only fully integrated pressurized sealing solution on the market.  Thanks to the combination of its patented positive pressure technology and tailored Hevvy Slurry Seals, the HNS submersible pump lasts longer and can pump more aggressive slurries than any other submersible pump.  The HNS offers unparalleled flexibility with modular selection of the pump wet-end, seal, motor, and accessories to best fit the application.

The Plenum54, the patented Hevvy Pressurized Slurry Sealing System, combines an internal self-generating pressurization system with Hevvy’s Slurry seal range.  Together, this creates an internal oil back pressure on the sealing area which at typical submergence depths will yield a greater internal pressure in the sealing chamber than the incoming slurry pressure, ensuring the ultimate seal life.

The new motor design is built for the most difficult slurry applications.
