What the A10VO does
The Rexroth A10VO is a variable displacement, swashplate-design axial piston pump for open circuits. It draws oil from the tank and delivers it to the working hydraulics. Pressure, flow, and power controls let it deliver only what the system demands, which saves energy and heat.
On a sideloader, an A10VO-type pump typically supplies the work hydraulics: mast or lift functions, tilt, steering, and auxiliary circuits, depending on the machine's design.
What the A4VG does
The Rexroth A4VG is a variable displacement axial piston pump for closed circuits, built for hydrostatic transmissions. Oil flows in a loop between pump and motor, so the pump controls both the speed and direction of the drive. Shifting the swashplate through zero reverses the flow, which gives smooth, stepless travel in both directions.
On a hydrostatically driven sideloader, an A4VG-type pump is typically the travel drive pump. It is designed for high working pressures, commonly in the 400 bar range, with a built-in charge pump and valves for a closed loop.
Why Rexroth Pumps Suit Sideloaders
Efficiency in demanding duty cycles
Sideloaders work in stop-start cycles with frequent direction changes, often outdoors and under load. Variable displacement pumps reduce wasted flow, which means less heat and lower fuel or energy consumption.
Controllability
Electro-proportional control on closed-circuit pumps lets operators creep precisely with long loads, then travel at speed when the aisle is clear. That matters when you are placing a six-meter bundle near racking.
Service network
Rexroth is among the most widely supported hydraulics brands. Reman units, seal kits, and trained technicians are easier to find than for niche alternatives, which shortens downtime.
Common Failure Signs
Loss of power or slow functions
Slow lifting, weak tilt, or sluggish steering can point to internal wear, a worn control valve, or contaminated oil. Check filters and the oil condition before blaming the pump.
Drive weakness or creeping
A machine that struggles uphill, drifts in neutral, or travels unevenly in one direction can suggest charge pressure problems, worn internals, or control faults. These symptoms overlap with drive motor wear, so diagnosis should test pressures rather than assume.
Noise, heat, and metal in the oil
Whining or knocking, rising oil temperature, and metallic particles in the filter all warrant immediate attention. Running a failing pump spreads debris through the whole system and turns one repair into several.

Q1: Is the A10VO or the A4VG the pump in a Baumann Side loader?
A1: It depends on the model. Many hydrostatic sideloaders use a closed-circuit pump like the A4VG for travel, and an open-circuit pump like the A10VO for work hydraulics, but configurations vary. Check the machine documentation and nameplates.
Q2: Do replacement pumps need calibration?
A2: Many do, especially pumps with electronic controls. Control settings and pressure limits must match the machine’s specifications.
Q3: What are the price and delivery time for the A10VO/A4VG hydraulic pump for the Baumann Side loader?
A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
