HYDROMATIK GMBH A2FM80/61L-PABXXX S 413284 211.19.01.02 3522981 09.94

Primary Function: In a hydraulic system, this unit is typically used as the main pump. It automatically adjusts its swivel angle (and thus output flow) to maintain a set system pressure. The auxiliary control allows for remote adjustment of the pressure setting or other parameters, often via an electrical signal.

Key Technical Specifications :

• Displacement: 80 cm³/rev
• Maximum Operating Pressure: Likely up to 350 bar (standard for series 61). Continuous pressure could be around 280 bar.
• Maximum Speed: Dependent on inlet conditions, but typically in the range of 3000 – 4000 rpm.
• Shaft: Special “L” design (e.g., splined or keyed).
• Control Type: PAB – Pressure compensation with auxiliary control device. This allows the pressure set point to be adjusted externally.
• Port Design: Standard rotation and port location. Specific port type (e.g., SAE flange) would be defined by the exact mounting code.
• Mounting: Standard SAE flange (e.g., SAE C or D mount).

1. HYDROMATIK GMBH: Original manufacturer (now Bosch Rexroth).
2. A2FM80/61L-PABXXX: The complete article number / order code. Defines the model, size, shaft, and control.
3. S 413284: Likely a serial number or a specific manufacturing batch code.
4. 211.19.01.02: This is a drawing number or part list number for the specific configuration or assembly.
5. 3522981: Possibly an internal order number, customer reference, or a variant code.
6. 09.94: Manufacturing date (September 1994).

• A2FM: Series designation for fixed displacement motors / variable displacement pumps in a bent-axis design.
• 80: Nominal displacement of 80 cm³/rev (cubic centimeters per revolution).
• 61: Design series/size (indicating mounting dimensions and pressure rating).
• L: Indicates a special shaft design. The “L” often means a splined shaft or a shaft with a keyway, differing from the standard.
• PABXXX: This is the control type code, which is the most critical part for functionality.
  • P: Pressure control (Pressure compensator, P constant).
  • A: Additional actuator (likely for a second control, e.g., electrical proportional control).
  • B: Control type variant.
  • XXX: Placeholder for more specific control options (e.g., voltage, adjustment range). A data sheet is needed for exact details. This makes it a variable displacement pump with pressure compensation and likely an auxiliary control option.
