1. Product Overview
This is an original double main hydraulic pump assembly for SANY SY980H. It consists of a Hengli Hydraulic V30GL280L main pump and an HP5V45-T2M2 pilot/auxiliary pump connected in series, equipped with an LRDRE1 electronic control regulator. It serves as the power core of the full electronically controlled hydraulic system.
Main Pump V30GL280L: Supplies high-pressure and large-flow main hydraulic power for the whole machine, driving the boom, arm, bucket, travel and swing mechanisms.
Auxiliary Pump HP5V45-T2M2: Delivers pilot control oil and flow for servo control and auxiliary movements.
LRDRE1 Control Unit: Integrates mechanical power limitation, electro-proportional displacement and pressure cut-off functions, perfectly adapting to heavy-load mining working conditions of SY980H.
2. Structure & Materials
Main Pump V30GL280L
- Pump Body: Made of high-strength ductile iron with integrated rear cover. Features high rigidity, effective vibration and noise reduction and low internal leakage.
- Piston & Cylinder Block: Adopts high-alloy wear-resistant steel with deep nitriding treatment. It withstands high pressure and impact, ideal for heavy mining operations.
- Valve Plate: Bronze alloy with high-precision grinding. Volumetric efficiency ≥ 97%, low wear and long service life.
- Swashplate & Return Mechanism: Forged alloy steel with excellent fatigue resistance and fast response, supporting stepless variable displacement.
- Seals: Imported FKM fluoroelastomer. Operating temperature: -40℃ ~ 120℃, anti-aging and leak-proof.
- Bearings: Reinforced heavy-duty roller bearings, capable of bearing high radial and axial loads.
Auxiliary Pump HP5V45-T2M2
- Structure: Compact swashplate piston pump with small size, light weight and high power density.
- Housing: High-strength aluminum alloy, lightweight with good heat dissipation performance.
- Piston & Valve Plate: Wear-resistant alloy with surface hardening treatment for long service life and low noise.
- Control System: Fixed displacement with pressure compensation, stably providing pilot pressure of 3.5 ~ 4.5 MPa.
Integrated Control Module LRDRE1
- Components: Equipped with electro-proportional solenoid, pressure cut-off valve, power spring and sensor ports.
- Functions: Electro-proportional flow regulation, mechanical power protection and high-pressure cut-off protection.

4. Control Principle & Functions
Electro-proportional Displacement Control (Main Pump)
Receives 4–20 mA signals from ECU to adjust swashplate angle steplessly. It precisely matches flow rate with load demands to achieve energy saving and high efficiency.
Mechanical Power Limiting (Main Pump)
Built-in power spring automatically matches the output power of DC16 engine to prevent engine stall under overload and ensure stable performance during heavy-load operation.
High-pressure Cut-off (Main Pump)
Automatically reduces displacement when system pressure exceeds 35 MPa, protecting pumps, valves and pipelines from damage caused by overpressure.
Pilot Pressure Stabilization (Auxiliary Pump)
HP5V45 steadily outputs 4 MPa pilot oil to control main pump displacement, multi-way valve switching, braking system and servo system.
Full Electronic Integrated Control (ICT)
Works in deep coordination with the electronic control system of SY980H. It realizes unpowered boom lowering and smooth compound movements, raising overall energy efficiency by over 30%.
5. Core Advantages
✅ Genuine Product & Perfect Fit: Customized exclusively for SANY SY980H. 100% compatible with original mounting dimensions, ports and control logic for plug-and-play installation.
✅ Heavy-duty & High-pressure Design for Mining: 35 MPa rated pressure and 40 MPa peak pressure. Excellent impact and contamination resistance, suitable for heavy-load operations in stone mines and coal mines.
✅ High Efficiency & Low Fuel Consumption: Full electronic and electro-proportional control realizes on-demand oil supply with low overflow loss, greatly cutting fuel consumption.
✅ High Reliability & Long Service Life: Fitted with reinforced bearings, wear-resistant pistons and premium seals. Designed service life ≥ 10,000 hours.
✅ Low Noise & Vibration: Integrated housing and optimized flow channels reduce vibration and noise, improving operating comfort.
✅ Compact Structure & Easy Maintenance: Series-connected dual pump design saves installation space. Modular control facilitates fault diagnosis and repair work.
6. Common Faults & Impacts
- Insufficient Flow / Slow Movements: Worn pistons, scratched valve plate or faulty electro-proportional valve → Weak digging force, uncoordinated compound actions and low working efficiency.
- Abnormal Pressure / Oil Overflow: Stuck pressure cut-off valve or seal leakage → High oil temperature, increased fuel consumption and vulnerable hydraulic components.
- Abnormal Noise & Excessive Vibration: Damaged bearings, loose pistons or insufficient oil suction → Severe pump vibration and loud noise; shutdown may occur in serious cases.
- Internal Leakage / High Oil Temperature: Aged seals and worn valve plate → System overheating, reduced efficiency and accelerated component aging.
- Unstable Pilot Pressure: Worn auxiliary pump or faulty overflow valve → Slow and jerky movements, and out-of-control operation.
