Rexroth A10VO swashplate axial piston hydraulic pump for the Metso Mobile crusher 16574315 9657663300 MM0301141 MM0335332 N02152028 N02152931

The A10VO is a variable-displacement, swashplate-design axial piston pump built for open hydraulic circuits. It belongs to Bosch Rexroth's long-standing A10V product family, which has become something of an industry benchmark for mobile and industrial hydraulics.

At its core, the pump works like this: a cylinder barrel houses a set of pistons arranged in a circle, parallel to the drive shaft. A swashplate — tilted at a variable angle — pushes those pistons in and out as the barrel rotates. The angle of the swashplate determines the stroke length of each piston, which in turn determines how much oil the pump displaces per revolution. Change the swashplate angle, and you change flow output — all without changing shaft speed.

Where the A10VO Fits in a Metso Mobile Crusher

Metso's mobile crushing and screening plants — the Lokotrack series being the best-known line — rely heavily on hydraulics for functions that would otherwise require complex mechanical linkages or multiple separate engines. A single diesel prime mover typically drives several hydraulic pumps off a shared gearbox or pump distribution drive (PDD), and the A10VO commonly serves as one of the primary or auxiliary pumps in that stack.

Typical Functions Powered

Track propulsion – many Lokotrack units use hydrostatic drive for crawling between sites; a variable displacement pump like the A10VO pairs naturally with a variable motor for smooth speed and torque control.

Crusher drive assist and lubrication circuits – supporting oil flow for jaw, cone, or impact crusher lubrication systems, which need steady, reliable flow regardless of engine load.

Conveyor drive circuits – feeding hydraulic motors on discharge and side conveyors.

Cooling fan drives – variable flow lets the fan speed track actual cooling demand rather than running flat-out, saving fuel and reducing noise.

Feeder and vibrating grizzly circuits – precise, load-sensing flow control helps match feed rate to crusher chamber capacity.

Energy Efficiency

Because displacement varies with demand rather than running at fixed output, the A10VO reduces parasitic hydraulic losses. On a diesel-powered mobile crusher, every liter of fuel saved on hydraulic overhead is a liter that either extends runtime or reduces operating cost — a real line item for contractors billing by the ton processed.

Serviceability and Parts Availability

Bosch Rexroth's global service and parts network is a quiet but significant factor. A crusher working a remote site in another country can usually source A10VO seal kits, control valves, or a full replacement unit faster than for a less common pump family. For rental fleets and international contractors, that logistics reality matters as much as raw performance specs.

Compatibility with Load-Sensing Systems

Metso's hydraulic architectures often use load-sensing logic to coordinate multiple functions running simultaneously — crusher lubrication, feeder, and conveyors all drawing from the same power source. The A10VO's LS and DFLR control variants integrate cleanly into these systems, letting the pump respond to the highest pressure demand signal across the circuit rather than requiring a dedicated pump per function.

Common Failure Points and Maintenance Considerations

Even a well-engineered pump has predictable wear patterns, and knowing them is half of good preventive maintenance.

Contamination Is the Number One Killer

Axial piston pumps run tight clearances between pistons, barrel, and swashplate. Contaminated hydraulic fluid — whether from a failed filter, a breached seal, or a sloppy fluid top-off in a dusty quarry — accelerates wear on these surfaces faster than almost any other factor. Sticking to the OEM's filtration micron rating and change intervals isn't optional on a crusher; it's the cheapest insurance available.

Cavitation and Inlet Starvation

If the pump's suction line is restricted — a collapsed hose, a clogged suction strainer, or fluid that's too viscous in cold weather — the pump can cavitate. This shows up as a distinctive whining or rattling noise and, left unaddressed, pits the piston shoes and swashplate surface.

Overheating

Hydraulic oil running consistently above recommended temperature thins out, loses film strength, and accelerates wear across the entire circuit, not just the pump. On mobile crushers working in hot climates or under continuous heavy load, oil cooler condition and fan drive function deserve regular checks.

Swashplate Control Linkage Wear

On mechanically actuated control variants, linkage wear or a sticking control piston can cause erratic flow response — the machine may surge, hunt, or fail to reach full displacement under load. This is often mistaken for a "pump failure" when it's actually a control-side issue that's cheaper to fix.

Q1: Is the A10VO the same pump used across all Metso Lokotrack models?

A1: No. Metso specifies pump displacement, control type, and configuration based on the specific model's hydraulic architecture and power requirements. The A10VO family covers a wide displacement range, so the exact unit on an LT96 will differ from what's fitted to a larger LT200 series machine.

Q2: How long does an A10VO pump typically last on a mobile crusher?

A2: With proper filtration, fluid maintenance, and normal operating temperatures, these pumps commonly run well beyond 10,000 hours before needing a rebuild. Actual life depends heavily on contamination control and duty cycle severity — dusty, high-load quarry work is harder on a pump than lighter recycling applications.

Q3:What is the price and delivery time of the A10VO hydraulic pump for the Metso Mobile crusher?

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
