Kawasaki K5V160 Pilot Gear Pump Assembly

The Kawasaki K5V160 pilot gear pump serves as a charge pump for the K5V160 series variable displacement axial piston main pumps. It is directly driven by the main pump drive shaft, providing hydraulic fluid to the control circuit for pressure compensation and flow regulation. The unit features a compact aluminum gear pump structure designed for high volumetric efficiency exceeding 92 percent. It is engineered as a critical component for the hydraulic systems of 30-37 ton class excavators. Primary applications include Doosan DH370, Daewoo Solar 370LC-V, and Sany SY285 excavators equipped with Kawasaki K5V160 main pumps. Cross-compatibility extends to Caterpillar E330D, E336D, Volvo EC300D, EC250D, Hyundai R330LC-9S, XCMG XE370, Sumitomo SH350, and Case CX360 platforms utilizing the K5V160 main pump series. The pump delivers a nominal displacement of 16/4.5 mL/r and weighs approximately 5.6 kg. It is constructed from high-strength aluminum alloy for the housing and hardened steel gears to withstand continuous high-pressure pilot circuit demands.
