JN250

JN250 high-pressure cleaning machine is an ultra-high-pressure plunger pump newly developed and produced by drawing on the advanced technology of the same industry. The product has the characteristics of compact structure, small size, light weight and high efficiency. The power end is an export box with forced lubrication. The high-speed shaft and crankshaft are driven by herringframe gears. The transmission is stable and reliable, the friction coefficient is reduced, the lubrication performance is improved, the noise is low, the temperature rise of the power end is reasonable, and the hydraulic end is easy to maintain and the operation is reliable. It is used for ultra-high pressure water jet cleaning, metal cutting, ship cleaning and rust removal, and descaling cleaning of condensers, heat exchangers, evaporation tanks and boilers in chemical plants, sugar mills, power plants, etc. Can transport water, emulsion and other similar water liquid.
