Komatsu PC360-7 Main Hydraulic Pump – China Remanufactured

Description

Detail Information

1. Key Features & Benefits

• Professionally remanufactured to Komatsu OEM standards – This main hydraulic pump has been fully disassembled, cleaned, crack-inspected, and rebuilt to meet Komatsu’s original equipment specifications. Every critical component – cylinder block, piston assemblies, valve plate, swashplate, bearings, and seals – is either renewed or replaced with new, high-quality parts. The result is restored hydraulic performance at a fraction of the cost of a new genuine pump.

• Direct replacement for Komatsu PC360-7 excavators – Specifically engineered for Komatsu PC360-7, PC360LC-7, PC360-8, PC350-7, PC300-7, and related 30–36 ton class excavators. This axial piston pump powers the boom, arm, bucket, swing, and travel circuits with the precise, high-volume flow required for heavy construction, quarrying, and mining operations.

• High-capacity hydraulic output for 36-ton class work – The PC360-7 is a 36-ton class excavator powered by the Komatsu SAA6D114E engine delivering 180 kW at 1,900 rpm. The hydraulic system delivers a maximum flow of 535 L/min and a main relief pressure of 37.3 MPa for the travel circuit and 27.9 MPa for the swing circuit. This provides the hydraulic power needed for fast cycle times, high bucket fill factors, and responsive multi-function operation.

• High-pressure capability for demanding applications – Rated for continuous operation at high pressures, with the ability to withstand extreme loads in construction, quarrying, and mining environments. This pressure capability delivers consistent digging force (227 kN bucket digging force) and swing torque hour after hour in the most demanding applications.

• Superior durability and contamination resistance – Utilizes high-strength alloy cylinder blocks and precision-lapped piston shoes to ensure minimal internal leakage and maximum volumetric efficiency. Equipped with oversized, low-friction bearings to withstand the high radial and axial loads generated during multi-function hydraulic movements. Premium seals and gaskets are installed to withstand extreme pressures and temperatures.

• Energy-efficient, optimized design – Features an optimized swash plate design that reduces heat generation and internal friction. The pump regulators are factory-calibrated to interface seamlessly with the Komatsu machine control system, ensuring smooth load-sensing and flow-sharing capabilities. A correctly functioning main pump ensures stable system pressure, safeguarding other costly components like control valves and hydraulic cylinders.

• Restores full hydraulic power – Effectively addresses issues like weak digging force, slow operation, and poor responsiveness, bringing your machine back to its intended productivity. A worn pump forces the engine to work harder – installing a remanufactured main pump helps maintain optimal fuel consumption.

• Direct bolt-on replacement – Mounting flange, drive shaft spline, and hydraulic port configurations are restored to original Komatsu specifications. No modifications, no adapters – your mechanic unbolts the old pump and bolts this one in.

• Pre-shipment visual verification – Before packing, we send you detailed high-resolution photographs of the actual unit (mounting flange, splines, port threads, castings, overall condition). You approve shipment – we never ship blind.

• Fast delivery – 5–8 working days lead time from our Guangzhou warehouse. Monthly supply capacity of 300 units, available for single-piece or bulk orders.

2. Applications

The remanufactured Komatsu PC360-7 main hydraulic pump is the power source for 36-ton class excavators used in the most demanding job sites:

• Large-scale construction & infrastructure – Highway excavation, dam building, bridge footings, and large-scale earthmoving projects. The pump’s 535 L/min flow and 37.3 MPa pressure capability deliver consistent digging force and swing torque hour after hour, while the energy-efficient design reduces fuel consumption across long shifts.

• Quarrying & aggregates – Loading trucks, stockpile management, and material handling in granite, limestone, and basalt quarries. The pump’s robust alloy cylinder blocks and precision-lapped piston shoes withstand abrasive dust conditions, while the load-sensing flow-sharing capability provides smooth, responsive operation for precise bucket control.

• Mining support – Site cleanup, road maintenance, drainage works, and equipment pad grading. A remanufactured pump with new bearings and seals provides predictable service life – avoiding costly unplanned downtime in remote mine sites.

• Demolition & scrap processing – Shock loads, vibration, and sharp debris are routine in demolition yards and metal recycling facilities. The pump’s reinforced structural design and heavy-duty bearings absorb these extreme conditions without premature wear.

• Equipment rental fleet – 36-ton excavators are high-value rental assets. A remanufactured pump offers predictable performance at a cost that makes proactive replacement financially sensible – avoiding costly mid-rental failures, towing bills, and customer complaints.

• Forestry & land clearing – Steep slopes, fallen timber, and uneven terrain demand reliable hydraulic performance. The pump’s consistent pressure output maintains stable power for saws, grapples, and mulchers, even under varying load conditions.
