SANY Material Code: 150106020004A
Applicable Model: SANY SY980H Mining Excavator (Scania DC16 Engine)
In Stock | Wooden Case Packaging | Price Negotiable
Supporting Service: We supply genuine full-range spare parts for SANY excavators to realize one-stop procurement.
1. Product Overview
This is an original combined pump assembly (dual piston pump) for SANY SY980H. It is composed of Hengli Hydraulic V30GL280L main pump and HP5V45-T2M1 pilot/auxiliary pump connected in series, equipped with LRDRE1 electronic control regulator. It acts as the power core of the fully electronically controlled hydraulic system of SY980H.
Main Pump V30GL280L: Delivers high-pressure and large-flow main hydraulic power for the whole machine to drive boom, arm, bucket, travel and swing devices.
Auxiliary Pump HP5V45-T2M1: Supplies pilot control oil as well as flow for servo control and auxiliary movements.
LRDRE1 Control Unit: Integrates mechanical power limitation, electro-proportional displacement and pressure cut-off functions, fully adapting to heavy-load mining conditions.
2. Structure & Materials
Main Pump V30GL280L
Pump Body: Made of high-strength ductile iron with integrated rear cover. It 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 is high-pressure resistant and impact resistant, suitable for heavy-duty mining operations.
Valve Plate: Bronze alloy processed by high-precision grinding, with volumetric efficiency over 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, working 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-T2M1
Structure: Compact swashplate piston pump with small size, light weight and high power density.
Housing: High-strength aluminum alloy, lightweight and with good heat dissipation.
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
Integrated Components: 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 matches flow rate with load accurately to save energy and improve efficiency.
Mechanical Power Limiting (Main Pump): The built-in power spring automatically matches the output power of DC16 engine to avoid engine stall caused by overload and ensure stable operation under heavy load.
High-pressure Cut-off (Main Pump): When system pressure exceeds 35 MPa, the pump automatically reduces displacement to protect pumps, valves and pipelines from overpressure damage.
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): It works in deep coordination with the electronic control system of SY980H, realizing unpowered boom lowering and smooth compound movements. The overall energy efficiency is increased by more than 30%.
5. Core Advantages
✅ Genuine Parts & Perfect Compatibility: Specially designed for SANY SY980H. 100% compatible with original mounting dimensions, ports and control logic for plug-and-play installation.
✅ Heavy-duty & High-pressure for Mining: With 35 MPa rated pressure and 40 MPa peak pressure, it features excellent impact and contamination resistance, ideal for heavy-load operations in stone mines and coal mines.
✅ High Efficiency & Low Fuel Consumption: Adopts full electronic and electro-proportional control to supply oil on demand, reduce overflow loss and greatly cut fuel consumption.
✅ High Reliability & Long Service Life: Equipped with reinforced bearings, wear-resistant pistons and high-quality seals. The designed service life is no less than 10,000 hours.
✅ Low Noise & Vibration: Integrated housing and optimized flow channels reduce vibration and noise for better operating comfort.
✅ Compact Structure & Easy Maintenance: Series-connected dual pump design saves installation space. Modular control facilitates fault diagnosis and maintenance.
6. Common Faults & Impacts
Insufficient Flow / Slow Movements: Worn main pump 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 easy damage to hydraulic components.
Abnormal Noise & Excessive Vibration: Damaged bearings, loose pistons or insufficient oil suction → Severe vibration and loud noise of the pump, and even shutdown in serious cases.
Internal Leakage / High Oil Temperature: Aged seals and worn valve plate → System overheating, reduced efficiency and accelerated aging of components.
Unstable Pilot Pressure: Worn auxiliary pump or faulty overflow valve → Slow, jerky movements and malfunction of control system.
