Bosch Rexroth A11VO A11VLO axial piston hydraulic pump for the Terex Material handler 142625162 32040200004 5364660790 5364662230 5364662412 6049657 84974140

The A11VO is a mid-to-large frame pump designed for mobile machinery. It is known for:

A compact, robust housing with a high power-to-weight ratio

Nominal pressures typically around 350 bar, with peak ratings higher

A wide choice of controls (pressure, load sensing, power, electro-proportional)

Through-drive options so auxiliary pumps can be stacked behind the main pump

The A11VLO is built for applications that want more flow from a pump of similar footprint. Its design supports higher speeds and larger displacements in the upper size range, which suits large machines with big engines. In practical terms, the A11VLO is the one you see where the machine's duty cycle demands sustained high flow.

Why Terex Material Handlers Use This Pump Class

Fast, repetitive cycles

Material handlers swing, boom, stick, and grapple almost constantly. The pump must change flow rapidly as the operator moves from lifting to swinging to grabbing. Swashplate pumps with load-sensing or electro-proportional control do this efficiently, delivering only the flow the valve block asks for.

Fuel efficiency

A fixed-displacement pump wastes energy by pushing oil over a relief valve when demand is low. A variable pump destroys less power as heat. Over thousands of hours, that shows up in diesel consumption and oil temperature.

Engine matching

Power-limiting controls let the pump reduce displacement when the engine is being lugged down. That prevents stalls and keeps the machine responsive, which matters in a handler where the engine is also driving a fan, an alternator, and sometimes an elevating cab system.

Serviceability

These pumps are widely supported through authorized distributors, and rebuilds, seal kits, and exchange units are available worldwide. For a fleet operator, that keeps downtime short.

Key Specifications to Verify Before You Buy

The details below should be matched to your machine, not assumed.

Displacement and size

Sizes are designated by a number representing displacement per revolution in cm³. Replacing a pump with a different size changes flow, system pressure behavior, and engine load. Match the original.

Rotation direction

Pumps are built for clockwise or counterclockwise rotation, viewed from the shaft end. A wrong-rotation pump can be destroyed in seconds.

Control type

Common control families in this pump class include:

Pressure control (DR / DRG): holds a set pressure and reduces flow

Load sensing (LR / DRS): responds to the valve block's flow demand

Power control: limits torque to protect the engine

Electro-proportional (EP / HD): responds to an electronic signal from the machine controller

A combination such as pressure cut-off plus load sensing plus power limiting is very common on handlers. Use the model code from your nameplate to confirm.

Mounting and shaft

Check the flange type, shaft spline, and through-drive configuration. Many replacement problems come from a pump that matches in displacement but not in mounting.

Port connections

Confirm SAE or metric port types for pressure, suction, case drain, and gauge ports.

Q1: What is the difference between A11VO and A11VLO?

A1: Both are open-circuit swashplate piston pumps. The A11VLO is aimed at higher-flow, larger-size applications, while the A11VO covers a wider range of sizes. Your machine's original pump determines which one fits.

Q2: What are signs the pump is failing?

A2: Slow or weak movements, high oil temperature, loud whining, metal particles in the filters or oil, and pressure that won't hold are the usual warning signs.

Q3: What is the price and delivery time of the A11VO/A11VLO hydraulic pump for the Terex Material handler?

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