JN200K/JN200Q

High Pressure Washer

Skid-mounted or trailer-mounted water blasters for high-efficiency cleaning of ship hulls, boilers, and heat exchangers

JN200K/JN200Q series of high-pressure washers features a compact structure, small footprint, and high efficiency. The power end adopts forced lubrication, with the high-speed shaft and crankshaft driven by herringbone gears, ensuring stable and reliable transmission. The design reduces friction, improves lubrication performance, lowers noise, and minimizes temperature rise, making it suitable for long-term continuous operation. The fluid end is easy to disassemble and maintain.

These washers are suitable for ultra-high-pressure water jet cleaning, metal cutting, ship hull descaling, and cleaning of equipment in chemical plants, sugar plants, and power plants, including condensers, heat exchangers, and reactors. They can also be used for pumping water, emulsions, and other liquids with water-like properties.
