description

15079594/17458125 axial variable piston pump acts as core hydraulic power source for Volvo A35/A40 articulated dump truck. Driven by the engine, it converts mechanical power into adjustable high-pressure hydraulic energy for body hoist, steering and brake assist hydraulic systems. Built-in load sensing control valve dynamically adjusts pump displacement based on real-time working load. When tipping fully loaded ore body, it provides large flow and high pressure; during highway or haul road cruising, it reduces displacement to save fuel and lower hydraulic heat accumulation. Core internal components including plungers, cylinder block, valve plate and slippers are made of high-strength alloy steel, processed with precision grinding and nitriding hardening. The friction pair maintains stable volumetric efficiency under continuous heavy cyclic loading and unloading. Reinforced cast iron housing is treated by stress relief annealing to eliminate casting residual stress, resisting torsional vibration and impact from rough mine haul roads.

advantage

- Load sensing curve calibrated for ultra-heavy mine ore tipping
The load sensing curve is specially calibrated for high-density ore tipping. It quickly builds high pressure under full payload, maintaining stable lifting speed even when lifting heavy ore loads with large density difference.
- High overload margin design to handle transient peak load during mine operation
Extra pressure margin reserved for sudden load spikes during uneven mine ground tipping, avoiding pump pressure overrun and internal component damage under momentary overload.
- Optimized flow distribution for multi-function parallel operation of heavy haulers
Fine-tuned flow distribution ensures hoist, steering and brake assist work simultaneously without obvious power grab, keeping vehicle controllable when unloading on sloped mine terrain.
- Reinforced anti-torsion pump housing for heavy articulated frame twisting
Thickened and rib-reinforced housing structure resists long-cycle torsional deformation from heavy articulated chassis movement, reducing the risk of housing crack under long-term mine operation.
- Optimized internal flow channel reduces heat generation under continuous high-load work
Refined internal flow path minimizes throttling loss during long-hour continuous operation, slowing oil temperature rise and reducing thermal aging of seals and hydraulic oil.

FAQ 

Q1: Which machine does 15079594/17458125 plunger pump fit?
A1: This hydraulic plunger pump is designed for Volvo A35 and A40 articulated dump truck, supplying hydraulic power for hoist, steering and brake assist. It cannot be used directly on A25/A30 series without confirmation. Confirm machine serial number before purchase.

Q2: What hydraulic functions does this pump support?
A2: It provides pressurized hydraulic oil for cargo body lifting and tipping, vehicle steering and brake assist. It is widely used for heavy ore and rock haulage in large open pit mines.

Q3: What are typical failure symptoms of worn pump?
A3: Typical symptoms: reduced tipping speed under full ore load, pressure drop during hoisting, steering stiffness while lifting body, obvious heat rise during continuous operation, abnormal pump noise and shaft seal oil leakage.

Q4: What checks should be completed before installing new pump?
A4: Inspect hoist cylinders, steering hydraulic circuit, brake assist valve and filter elements. Thoroughly flush hydraulic tank and pipelines to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: Why the dump truck still lacks lifting capacity after pump replacement?
A5: The problem may not be caused by pump. Check relief valve setting, stuck valve spool, blocked filter, damaged hoist cylinder seals or trapped air in hydraulic circuit. Air bleeding is required after installation.
