CAMAS, Washington -- Hotsy has added NESTechnology to its Hotsy high-pressure pumps. According to the company, NESTechnology, or Nested Seal Technology, is 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.
The 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, the company says
Other features of the new Hotsy high-pressure pump include:
• 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
• The nesting assembly is stronger and holds up better to spikes in water pressure, which occur every time the pressure washer's gun is triggered.
