- 1:1 OEM full interchange, zero modification installation
Manufactured strictly according to Volvo OEM drawings for F/G series trucks. All mounting holes, oil ports and spline shaft dimensions match VOE15191773. 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.
- 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 VOE15191773 plunger pump?
A1: This main hydraulic pump is designed for Volvo A35F, A40F, A35G, A40G articulated dump trucks. It is only compatible with F/G generation models, not for old D/E series. Please verify machine model and original part number before ordering.

Q2: What is the difference between 15191773 pump and D-series main pump?
A2: They have different displacement and control parameters. VOE15191773 is specially tuned for F/G generation electronic control system, not interchangeable with D generation pumps such as 11707968 and 11707970.

Q3: What faults appear when the 15191773 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.
