Hotsy pump

Additional benefits of using the Hotsy high-pressure pump with NESTechnology are:

Longer Seal Life with the Hotsy Pump
The unique technology of the nesting assembly includes new high and low-pressure U-shaped seals surrounded by thicker brass pressure rings. This provides better wall support while withstanding higher water temperatures. This results in Hotsy pumps having 3 times the seal life over similar pumps in the industry.

What is NESTechnology? It stands for Nested Seal Technology, where the pump actually nests the seals of the pumps high-pressure packing assembly in place, supporting the side walls, and resulting in greatly increased seal life.
