Rexroth A6VE 28/55/80/107/160/250 Hydraulic Piston Pump with Closed Loop Control for Heavy Equipment
The Rexroth A6VE 28/55/80/107/160/250 hydraulic piston pump serves as the core power component in heavy-duty hydraulic drive systems, featuring extensive variable control options and exceptional power density. This advanced pump efficiently converts hydraulic energy into mechanical energy while enabling stepless adjustment of output speed and torque for diverse operating conditions.
The A6VE piston pump operates on the inclined disc axial piston principle. High-pressure oil drives plungers in reciprocating motion, with the plunger assembly applying force to the inclined plate to rotate the output shaft connected to the cylinder body. Precise adjustment of displacement and output torque is achieved by modifying the tilt angle of the inclined plate.
- High Performance: Capable of withstanding high working pressures with wide speed range and robust power output
- Efficient Variable Control: Supports multiple control methods including electro-hydraulic proportional (ED), hydraulic remote (HD), constant power (LA) for precise operation
- Extended Service Life: Heavy-duty bearing design, optimized friction pairs, and internal circulation lubrication ensure durability in harsh environments
- Low Noise Operation: Advanced manifold design minimizes pressure pulses and operating noise
- Modular Design: Multiple displacement options (28/55/80/107/160/250 ml/r), shaft ends, flanges, and control configurations support custom solutions
| Control Type | Description | Applications |
|---|---|---|
| HD Control | Hydraulic remote control via external hydraulic signals | Basic hydraulic systems |
| ED Control | Electro-hydraulic proportional control using electrical signals (0-10V) for integration with automation systems | PLC-controlled automation |
| LA Control | Pressure-related automatic control / constant power control prevents engine overload | Excavators, heavy equipment |
| DA Control | Dual control combining pressure and speed sensing functions | Complex drive systems |
| EZ Control | Electric control via servo motors | Precision applications |
The Rexroth A6VE variable displacement motor is widely utilized in applications requiring broad stepless speed regulation and strong driving force:
- Construction Machinery: Excavator walking drives, rotary drilling rig main winches, concrete pump truck mixing systems, crane slewing mechanisms
- Mining Machinery: Underground loaders, mining drilling rigs, conveyor belt drives
- Agricultural Machinery: Large combine harvester walking systems
- Marine Engineering: Deck machinery (winches, anchors), servos
- Industrial Applications: Injection molding machines, metallurgical equipment, test bench drivers
Selecting the appropriate A6VE hydraulic pump model requires comprehensive consideration of these parameters:
- System Pressure: Maximum continuous working pressure and peak pressure requirements
- Displacement Needs: Required maximum and minimum displacement (ml/r)
- Control Method: Based on automation level and functional requirements
- Installation Interface: Flange standards (SAE, ISO) and shaft extension configuration
- Additional Functions: Integration of flushing valves, parking brakes, or oil replenishment pumps
