Product Description
K5V80DT-9N-12T Hydraulic Main Pump Doosan DX150-7 Excavator Parts Digger Spare Construction Machinery Parts
This replacement hydraulic main pump is compatible with most medium and large excavators, serving as the core engine-driven power source for hydraulic systems. It converts mechanical energy into high-pressure hydraulic oil to support boom, arm, bucket, travel and swing functions. Featuring universal axial variable piston structure, the dual main pump with rear pilot pump provides 28~35MPa high-pressure power output and 3~4MPa low-pressure control oil. The standard assembly includes cylinder block, piston groups, adjustable swash plate, flow regulator and distribution valve plate, enabling flexible adjustment of displacement, flow rate and fuel usage. Equipped with complete constant power, load sensing and pressure cut-off protection functions, the pump prevents engine stalling under heavy loads, reduces idle fuel loss and avoids hydraulic component damage from overpressure. It solves common pump failures such as weak machine action, engine black smoke, hydraulic oil overheating and abnormal operating noise. Simple daily maintenance including regular filter and oil replacement, airtight pipeline inspection and correct oil level maintenance effectively extends pump service life.
