・Universal A10VO compact structure, easy maintenance for multi-model fleet
Classic A10VO compact design fits a full range of Volvo A-series articulated dumpers. One spare pump covers multiple machine models, greatly reducing spare parts inventory pressure for mining operators.
・Nitrided alloy steel friction pairs, excellent wear resistance under long mining cycles
Core plunger, cylinder block and valve plate adopt nitriding hardening treatment, improving surface hardness and abrasion resistance. It maintains high volumetric efficiency under continuous heavy-load transportation and reduces internal leakage.
・High-precision swash plate variable regulator, fast response to load fluctuation
Built-in variable control assembly quickly adjusts displacement according to steering resistance and fan load. It balances power output for steering and cooling circuits, prevents power waste and protects hydraulic components from overload damage.
・FKM high-performance sealing system, reliable anti-leakage performance under high temperature
High-quality fluorine rubber seals resist high temperature and hydraulic oil aging. It effectively avoids internal and external oil leakage, keeps system pressure stable even during long-hour continuous operation.

FAQ 

Q1: What Volvo articulated dump truck models does VOE11116529 fit?
A1: It is compatible with Volvo A25/A30/A35/A40 D/E/F/G series articulated dump trucks. Please confirm OEM part number VOE11116529 before ordering.

Q2: What are the main functions of VOE11116529 auxiliary piston pump?
A2: It supplies hydraulic oil for power steering and cooling fan hydraulic circuit, independent from the main hoist pump for cargo box lifting.

Q3: What will happen if this pump fails during mine operation?
A3: Steering effort becomes heavy, cooling fan speed drops, engine overheats, hydraulic pressure fluctuates and abnormal humming noise occurs.

Q4: Why is this pump widely used for Volvo A-series dump fleets?
A4: It supports a wide range of machine generations, one spare part can serve multiple models, which helps mining clients simplify spare part management.

Q5: What maintenance measures help extend pump service life?
A5: Maintain clean hydraulic oil, replace filters on schedule, avoid continuous high-temperature operation, inspect seal condition and monitor system pressure regularly.
