Rexroth A10VSO140 140CC Hydraulic Pump  Ready Stock for Mining and Construction Equipment

Our factory supplies high quality Rexroth A10VSO140 140CC hydraulic pump with ready stock, customized for heavy-duty mining and construction equipment. Built with mature swashplate axial piston layout, this variable displacement hydraulic pump perfectly combines precise hydraulic control and solid mechanical construction, delivering compact power density and ultra-stable adjustable hydraulic flow to cut fuel consumption for all kinds of heavy machinery.

Swashplate Piston Working Principle of Rexroth A10VSO140 140CC Hydraulic Pump

Rotary Reciprocating Oil Absorption & Discharge Structure

Inside the Rexroth A10VSO140 hydraulic pump, multiple pistons are evenly installed on a concentric cylinder block surrounding the drive shaft. Each piston end is equipped with a sliding shoe that fits tightly against the inclined swashplate. When the drive shaft drives the cylinder block to rotate continuously, the fixed tilt angle of the swashplate pushes each piston to reciprocate in the cylinder bore. Pistons retract to suck low-pressure hydraulic oil and stretch out to output high-pressure fluid, forming continuous hydraulic power conversion. Unlike fixed-displacement pumps, the swashplate angle of A10VSO140 can be adjusted dynamically via a built-in hydraulic servo piston to change real-time displacement.

SO Pressure Compensation Intelligent Variable Control

The SO pressure compensation system is the core intelligent feature of our ready stock Rexroth A10VSO140 140CC hydraulic pump, equipped with load-sensing real-time pressure monitoring function. The built-in control valve continuously tracks circuit pressure; once the hydraulic actuator reduces working load demand, the control assembly instantly narrows the swashplate angle and lowers pump displacement to lock preset system pressure at 250 bar by default. This on-demand flow supply eliminates massive energy loss and heat accumulation caused by overflow valves, greatly improving energy efficiency for mining and construction equipment. Users can tweak the external spring to adjust target holding pressure flexibly.

Pressure Parameters & High Efficiency Performance

As a 140CC displacement hydraulic pump, the Rexroth A10VSO140 supports long-term stable continuous working pressure up to 280 bar, and withstands instantaneous peak pressure reaching 350 bar to handle heavy impact loads from mining machinery. Optimized internal flow channels, refined piston movement tracks and premium sealing fittings greatly reduce internal volumetric leakage and mechanical friction loss. More horsepower output from diesel engines or electric motors can be converted into effective hydraulic power, lowering long-term operation costs for construction fleets and mining stations.

Heavy-Duty Wear-Resistant Design For Long Service Life

This high quality Rexroth A10VSO140 hydraulic pump is manufactured to adapt to harsh dusty mining and construction working environments. It adopts reinforced tapered roller bearings to bear heavy axial and radial shaft loads from direct drive connections. Independent case drain channels and forced pressurized lubrication keep all friction components fully cooled and lubricated during continuous operation. If users maintain hydraulic oil cleanliness above ISO 18/16/13 standard, this ready stock A10VSO140 pump can extend maintenance cycles, reduce equipment downtime and improve total investment return.

Modular Multi-Control Options For Customized Mining & Construction Machinery

The full A10VO and A10VSO pump series share universal modular platform design. For our ready stock Rexroth A10VSO140 140CC hydraulic pump, you only need to replace the rear control cover to switch control modes without changing the main pump housing, covering three mainstream control versions:

• LR Constant Power Control: Caps maximum input horsepower to prevent engine stall under heavy mining load
• DFR Electro-Proportional Control: Supports remote electronic signal adjustment for stepless pressure and flow regulation, matching intelligent automated construction equipment
• DR Load-Sensing Control: Suitable for multi-valve composite hydraulic circuits of large excavators and mining loaders

This unified hardware platform simplifies machinery manufacturers’ design cycles and cuts spare parts inventory pressure.

Main Application Scenarios Of Rexroth A10VSO140 Hydraulic Pump

Mining & Construction Mobile Machinery

This high quality A10VSO140 140CC hydraulic pump is the core power source for large excavators, telescopic handlers, forestry harvesters and underground mining loaders. Its built-in pressure compensation delivers smooth, shock-free cylinder movement for precise digging and lifting operations, while automatically absorbing impact pressure to protect the whole hydraulic pipeline system of construction and mining equipment.

Industrial Manufacturing Hydraulic Equipment

For plastic injection molding machines, die-casting devices and heavy industrial hydraulic presses, Rexroth A10VSO140 provides stable long-term pressure holding to guarantee consistent finished product quality. Low running noise improves factory workshop environments, and high efficiency cuts power consumption for cyclic high-load industrial production lines.

Hydraulic Test Bench & Motion Simulation Equipment

Thanks to its ultra-stable, repeatable pressure and flow output, the ready stock Rexroth A10VSO140 hydraulic pump is widely applied on material fatigue test rigs and motion simulation platforms that require accurate, reproducible hydraulic power output.

Installation Guidelines & Daily Maintenance Troubleshooting

Standard Installation & Commissioning Tips

Accurate drive shaft alignment within official tolerance range is mandatory to avoid premature bearing and shaft seal damage of your Rexroth A10VSO140 hydraulic pump. Before initial startup, fully fill the pump housing with clean qualified hydraulic oil, and complete full system power flushing to remove manufacturing residual contaminants. During commissioning, set the pressure compensator to the minimum required working pressure to reduce thermal load and maximize energy savings for mining and construction equipment.

Common Faults & Root Cause Analysis

1. Low volumetric efficiency & excessive case drain oil flow: Caused by worn cylinder block valve plates or piston shoe abrasion, mostly triggered by particulate contaminated hydraulic oil or degraded oil lubricity
2. Loud running noise & cavitation erosion: Resulting from blocked suction strainers, undersized inlet hoses, high oil viscosity under cold startup or air leakage from the input shaft seal; worn bearings will also produce distinct grinding sounds
3. Cannot reach preset compensator holding pressure: Arises from fatigued or misadjusted control springs, clogged control orifices, or severe internal leakage of servo piston sealing rings that limit full swashplate stroke
