description

VOE11707970 axial variable piston pump acts as the core hydraulic power source for Volvo A35D and A40D articulated dump trucks. Driven by engine, it converts mechanical power into high-pressure hydraulic energy to supply variable flow and pressure for cargo box lifting and hydraulic actuators. The built-in swash plate variable control mechanism adjusts displacement dynamically according to load changes under no-load, light-load and heavy-load conditions, achieving optimized power matching and reducing unnecessary power consumption.
Core parts are manufactured from high-strength alloy steel. Plungers, cylinder block, valve plate and sliding shoes go through precision grinding and nitriding hardening treatment for superior wear and fatigue resistance, suitable for repeated lifting and dumping cycles in mines. Thickened cast iron pump housing adopts stress-relief annealing process to eliminate internal stress, resisting cyclic pressure shock and strong vibration, avoiding pump body deformation and cracking.

advantage

- Intelligent swash plate variable control, energy-saving & optimized power matching
High-precision swash plate mechanism automatically adjusts displacement following load changes. Low power output at light load to save fuel; higher flow & pressure for heavy lifting, reducing engine power waste.
- Thickened cast iron pump body, strong impact resistance for mining sites
Thick high-density cast iron housing with stress-relief annealing. It withstands continuous vibration and cyclic pressure shocks in quarries and mines, preventing pump deformation and cracking.
- High-performance FKM sealing system, resistant to high temperature & pressure
Imported FKM seals maintain reliable sealing under high pressure and high temperature. Reduce internal leakage and external oil seepage, stabilize system pressure and lower heat generation.
- Strict factory full inspection, stable performance & low failure rate
Each pump undergoes hydraulic bench tests including pressure holding, flow detection and variable response inspection before delivery. Strict QC ensures consistent performance meeting OEM standards.

FAQ 

Q1: Which Volvo equipment fits VOE11707970 plunger pump?
A1: This main hydraulic pump is for Volvo A35D, A40D articulated dump trucks, only for D-series models, not compatible with E/F/G versions. Please verify machine model and original part number before ordering.

Q2: What is the difference between 11707970 pump and 11707966 auxiliary pump?
A2: They are two independent hydraulic power units. VOE11707970 is the main pump for cargo lifting; VOE11707966 is auxiliary pump for steering and fan circuit. They work separately without interference.

Q3: What faults appear when the 11707970 pump wears out?
A3: Typical symptoms: slow box lifting, insufficient full-load lifting force, system pressure drop, unstable hydraulic pressure, pump abnormal noise and vibration, or continuous hydraulic overheating in severe cases.

Q4: Can I install this plunger pump directly without modification?
A4: Yes. All mounting dimensions, oil ports and spline shaft match OEM. Direct bolt-on installation, no cutting or welding required, simplifying maintenance.

Q5: What hydraulic oil and working environment are recommended?
A5: Use ISO VG46 anti-wear hydraulic oil. Working temperature: -25℃ ~ 110℃. Suitable for mining & earthwork. Avoid long-time overload, overheating and mixing different hydraulic oils.
