- 1:1 OEM full interchange, zero modification installation
Manufactured strictly according to Volvo loader OEM drawings. All mounting holes, oil ports and spline shaft dimensions match VOE11172358. 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 loading, reducing engine power waste.
- Thickened cast iron pump body, strong impact resistance for construction sites
Thick high-density cast iron housing with stress-relief annealing. It withstands continuous vibration and cyclic pressure shocks on job sites, 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 VOE11172358 plunger pump?
A1: This main hydraulic pump is designed for Volvo L60E, L60F wheel loaders, also compatible with L70E/L70F/L90E/L90F. Not suitable for other loader series. Please verify machine model and original part number before ordering.

Q2: Can this pump replace main pump for L110E/L120E?
A2: No. VOE11172358 has different displacement and installation parameters, cannot be interchanged with L110/L120 series hydraulic pumps.

Q3: What faults appear when the 11172358 pump wears out?
A3: Typical symptoms: slow boom lifting, weak bucket breakout 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 cylinders. Bleed air fully after installation to avoid cavitation damage.
