Danfoss mining truck double gear pump
Danfoss Tandem Gear Pump for Mining Trucks
Danfoss tandem gear pumps are specifically engineered for the rigorous operating conditions of mining trucks, delivering reliable hydraulic power to support critical on-board functions. As a core component of the mining equipment hydraulic system, this pump integrates two gear pump sections into a single compact housing, sharing a common drive shaft to provide dual independent hydraulic circuits or combined high-flow output, perfectly matching the multi-hydraulic-system requirements of mining trucks such as steering, braking, and lifting operations.
Core Features & Advantages
- Rugged Construction for Extreme Environments: Adopting high-strength cast iron housing and precision-machined gear sets, the pump is capable of withstanding extreme pressures up to 276 bar (4,000 psi) and intermittent temperatures as high as 115°C (239°F). The robust structure ensures stable operation even in dusty, vibrating, and high-impact mining environments, significantly reducing downtime.
- High Efficiency & Energy Saving: Equipped with an advanced pressure-balanced thrust plate design and low-friction internal components, the pump minimizes energy loss and improves volumetric efficiency. The optimized gear meshing design reduces internal friction, while the Teflon® coated bushings enhance wear resistance and extend service life under harsh conditions. Compared with conventional pumps, it can achieve up to 6% higher mechanical efficiency, translating directly into reduced fuel consumption for mining trucks.
- Compact & Modular Design: The integrated tandem structure saves valuable installation space in the mining truck engine compartment, with a 33mm shorter length than similar products in the industry, facilitating flexible layout and easy maintenance. Multiple modular configurations are available, including various displacement combinations, shaft types, and port positions (side or rear ports), to meet the customized needs of different mining truck models.
- Reliable Sealing & Long Service Life: High-temperature Viton® seals are adopted to adapt to the high-temperature operating environment of mining trucks, preventing hydraulic oil leakage. The one-piece gear shaft construction and high-quality steel-backed bronze bearings ensure strong radial load-carrying capacity, while the built-in oil drainage and return grooves reduce bearing load and wear, extending the overall service life of the pump.

Application Advantages in Mining Trucks
Mining trucks operate in extremely harsh and demanding environments, requiring hydraulic components to deliver consistent performance and high reliability. Danfoss tandem gear pumps are tailored to these needs with the following application-specific advantages:
- Dual-Circuit Power Supply: The tandem design enables simultaneous supply of hydraulic power to two independent systems (e.g., steering and braking, or lifting and tilting), eliminating the need for multiple independent pumps, reducing system complexity and installation space.
- Enhanced Operational Efficiency: The high flow rate and efficiency of the pump ensure rapid response of mining truck hydraulic systems, improving loading and unloading efficiency and overall operational productivity. The 6% higher mechanical efficiency compared to competing products reduces fuel consumption and operating costs significantly.
- Strong Environmental Adaptability: The rugged cast iron construction and advanced sealing technology allow the pump to resist dust, vibration, and extreme temperatures commonly encountered in mining sites, ensuring stable operation even in the most challenging conditions.
- Proactive Maintenance & High Uptime: Compatible with Danfoss Plus+1® control system, the pump can be integrated with remote monitoring solutions (e.g., DrivePro®), enabling real-time monitoring of operating status, early detection of potential faults, and implementation of proactive maintenance to minimize unplanned downtime.
