The Hotsy pump - engineered for durability & performance. Providing 3 times longer seal life.

Hotsy Pumps featuring NESTechnology™
Hotsy is introducing the latest innovation to the Hotsy pump - NESTechnology™.

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

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.

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

• Extended time between seal replacement, greatly reducing maintenance costs.
• Teflon bronze rings support the U-Seal to prevent premature wear and loss of pressure.
• The low-pressure U-Seal has a unique double lip to provide for greater suction and less chance of water leakage.
• Increased wall thickness of the brass pressure rings resist cracking and provide a solid foundation for the seals.
• The nesting assembly is stronger and holds up better to spikes in water pressure, which occur every time the gun is triggered.
• Existing Hotsy pumps can be upgraded to utilize NESTechnology’s unique nesting assembly. All parts are interchangeable, and fit within the brass manifold.
