description

11707968 axial variable piston pump serves as the core main power source of the working hydraulic system for Volvo A35D and A40D articulated dump trucks. Driven by the engine, it converts mechanical energy into high-pressure hydraulic energy, providing stable variable flow and pressure support for cargo box lifting and core hydraulic execution circuits. The built-in high-precision swash plate variable control mechanism can intelligently adjust pump displacement in real time according to different load changes such as no-load, light-load and heavy-load lifting, realizing accurate power matching, effectively reducing invalid power loss and engine load, and achieving energy-saving and efficient operation.
The core components of the pump adopt high-quality high-strength alloy steel materials. After precision grinding, surface nitriding hardening and anti-fatigue treatment, the plunger, cylinder block, valve plate and sliding shoe friction pairs have ultra-high surface hardness and excellent wear resistance, which can adapt to long-term frequent lifting and dumping cycle operations of mining vehicles. The pump body is made of thickened high-density cast iron and processed by stress-relief annealing technology, which completely eliminates internal structural stress, effectively resists cyclic pressure impact and strong vibration generated by harsh working conditions, and avoids pump body deformation and cracking.

advantage

- 1:1 OEM full interchange, zero modification installation
Manufactured strictly according to Volvo OEM drawings. All mounting holes, oil ports and spline shaft dimensions match VOE11707968. Direct bolt-on replacement without pipeline modification, cutting downtime and maintenance cost.
- Nitrided alloy steel friction pairs, superior wear resistance & long service life
Plunger, cylinder block, valve plate and sliding shoe use high-strength alloy steel with deep nitriding and precision grinding. High hardness and anti-fatigue performance maintain stable volumetric efficiency under frequent heavy-duty cycles and reduce internal leakage.
- 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.

FAQ 

Q1: Which Volvo equipment fits VOE11707968 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 11707968 main pump and 11707966 auxiliary pump?
A2: They are two independent hydraulic power units. VOE11707968 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 11707968 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 pre-installation work is needed to extend pump service life?
A5: Replace hydraulic oil and filters, flush tank and pipelines to remove metal debris. Inspect valve block and lifting cylinder. Bleed air fully after installation to avoid cavitation damage.
