Hydraulic pumps are a vital part of hydraulic systems, determining flow rate, pressure and efficiency. The A2FO series from Bosch Rexroth is an axial piston fixed pump designed for industrial applications. This blog post will explain the main specifications, performance features and applications of the A2FO axial piston fixed pump.
A2FO Series Overview
The A2FO series is an axial piston fixed pump, meaning the pumping pistons are arranged axially along a shaft rather than radially. Some key details:
- Piston design: The pistons are oriented parallel to the pump shaft and move axially in and out of cylinder bores to pump fluid.
- Montage: The pumps are designed for fixed mounting to a system, rather than mounting on a swing plate.
- Control: The delivery flow rate can be controlled by either rotating the shaft speed or tilting the swashplate angle.
- Caractéristiques: The pumps offer high efficiency, smooth flow, good controllability and compact design.
- Médias: The pumps can handle various hydraulic fluids like mineral oils, HFA fluids and fire-resistant fluids.
- Output: The A2FO series provides flow rates from 0.4 à 110 L/min and pressures up to 350 bar.
Axial Piston Fixed Pump Specifications
The main specifications of the axial piston fixed pump A2FO include:
- Mounting position: Optional vertical or horizontal mounting
- Rotation: Optional clockwise or counter-clockwise shaft rotation
- Ports: Optional SAE-A, SAE-B or DIN/ISO ports
- Swashplate tilt: 0 to ±13 degrees
- Servos: Hydraulic or mechanical (ball-ramp) options
- Weight: Dependent on size from 3 à 30 kg
- Cooling: Either air, liquid or oil immersed
- Efficiency: Up to 94%
- Noise: As low as 70 db(UN)
Performance Features Of Axial Piston Pump
The A2FO axial piston pump design offers several benefits:
- High efficiency – Provides up to 94% overall efficiency through reduced internal losses.
- Smooth flow – The axial piston design produces pulsation-free flow for low noise.
- Compact – The axial arrangement of pistons results in a short, space-saving design.
- Cylindrée variable – The swashplate angle can be varied to precisely control flow rate.
- Fiable – The hydrostatic bearings and few moving parts provide a long service life.
- Heavy duty – Suitable for demanding industrial applications.
- Flexible – options for porting, rotation, mounting and servos offer flexibility.
