Manufactured by Zhejiang Danau Industries Co., Ltd., this high-pressure pump is commonly used as a genuine replacement pump in high-flow pressure washer systems such as Gorilla and Kiam units, and is compatible with machines powered by Honda GX390, Loncin, and similar 13 HP gasoline engines.
The pump features a forged brass manifold for excellent corrosion resistance, an anodized aluminum crankcase with cooling fins for efficient heat dissipation, and ceramic-coated plungers designed to provide extended wear resistance and long service life.
Its triplex plunger design delivers smoother water flow, improved efficiency, and greater durability compared to standard axial pumps, making it suitable for demanding commercial and industrial applications.
A detachable and pressure-adjustable unloader valve with detergent injector capability allows precise control of output pressure and supports soap application for enhanced cleaning performance.
