Bosch Rexroth ALA10VO variable hydraulic pump for the Soilmec Engineering Equipment 50770111 50770219

- FAQ
The ALA10VO is a swashplate-design axial piston pump for open-circuit systems, meaning it draws oil from a tank and returns it there. Its core features are:
Variable displacement: the swashplate angle sets flow, so the pump delivers only what the circuit demands.
Medium-pressure rating: typically 280 bar nominal and up to 350 bar peak in common series (series 31 is the one most technicians encounter). Check the datasheet for your exact series.
Multiple frame sizes: commonly from about 18 up to 140 cm³/rev, depending on series.
Through-drive option: allows tandem pump stacks driven from a single engine or motor shaft.
Multiple controller options: pressure, flow, load-sensing and power control.
Why the ALA10VO Fits Soilmec Style Foundation Rigs
Variable flow saves fuel and heat
Drilling is not steady-state work. A rotary rig cycles between drilling, tool extraction, casing handling and repositioning. A fixed-displacement pump wastes energy in every idle moment. A variable pump destrokes and delivers only what's needed, which lowers fuel burn and reduces oil temperature, a real advantage in hot-climate jobsites.
Compact, robust construction
Piling rigs are cramped, dusty, and shaken constantly. The A10VO's compact footprint and proven mechanical design have made it a staple on mobile machinery for decades.
Tandem pumps from one engine
The through-drive lets a designer stack pumps on a single power take-off. On a rig, that might mean one pump for the rotary head and another for auxiliary functions, all driven by the diesel engine.
Maintenance Best Practices
1. Keep the oil clean. Contamination is the leading killer of axial piston pumps. Follow the fluid cleanliness targets in the manufacturer's documentation and change filters on schedule.
2. Monitor case drain flow. It's the simplest health indicator you have.
3. Fill the pump case before start-up. Running a new or rebuilt unit dry will destroy it quickly.
4. Check suction conditions. Undersized or restricted suction lines cause cavitation, which sounds like gravel and erodes the internals.
5. Sample the oil. Regular analysis catches wear metals early.
6. Use authentic or properly certified parts. Counterfeit and mismatched components are a genuine risk in the aftermarket.
