RITO Hydraulic Piston Pump 9285566 ZX130LCN-3 HPK060 Tandem Pump Assembly 9285685 9290597 ZX130-3 Excavator Main Pump

Unstable hydraulic delivery in ZX130LCN-3 excavators can quickly translate into weaker digging force, slower cycle response, and reduced productivity during continuous operation. The 9285566 / 9285685 / 9290597 HPK060 tandem pump assembly is developed to re-establish stable axial piston performance, ensuring consistent pressure output across ZX130-3 and ZX130LCN-3 machine platforms.
