Product Descriptio

This piston hydraulic pump is the main hydraulic pump assembly specifically designed for the PC78-6 and PC78US tailless small excavators. As the power core of the entire machine's hydraulic system, it continuously supplies high-pressure hydraulic oil for all actions such as digging, rotation, movement, and earth-moving trowel. It directly determines the excavation power, action response speed, and operational smoothness of the equipment.

The pump housing is made by casting high-strength cast iron as a single piece, with a thick and sturdy structure. It has excellent shock resistance and impact resistance, and can adapt to the harsh working environment on construction sites with high dust, humidity, and continuous vibration and impact for a long time. It is unlikely to crack or deform due to long-term continuous operation. The pressure and flow adjustment components are precisely calibrated at the factory, and the pressure response curve perfectly matches the original machine's engine power, effectively avoiding problems such as engine stalling, rapid increase in hydraulic oil temperature, and vehicle stalling. This significantly reduces the downtime for equipment failures and ensures uninterrupted construction of small-scale projects.
