Whether you’re considering purchase of your first Hotsy cleaning equipment or a pressure washer pump replacement, you can count on our excellent service and reliability to keep things running.

Hotsy Pumps featuring NESTechnology™

Now, with the latest innovation of NESTechnology™, Hotsy outshines other pressure washer pump brands with extended service life. Hotsy pumps use the latest innovation to seal technology - 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 3 times the seal life over similar pumps in the industry.
