Eternal Hydraulic – Rexroth Type A4FO A4FM Fixed Piston Pump/Motor Series 10 and 30
A4FM rexroth type fixed displacement hydraulic motor of swashplate design are used for hydraulic drives in open loop circuits. Flow is proportional to the drive speed and to the displacement, has good suction characteristic, low noise level and long service life. It’s pump combinations possible, and can through drive for mounting other pumps.
- Particularly well suited for applications, where compact installation size is required
- High tolerance to torsional vibrations
- Long service life at high pressures
- Very high total efficiency
- Low operating noise
- Swashplate design
- High pressure motor for confined installation spaces
- Size 71 … 500
- Nominal pressure 350 bar
- Maximum pressure 400 bar
- Open and closed circuits

APPLICATION
Piston pumps are widely used in high-pressure, high-flow, high-power systems and where the flow needs to be regulated, such as mobile and construction equipment, engineering vehicles, heavy-duty planers, metal forming and stamping, machine tools, hydraulic presses, oilfield equipment, mining and metallurgical machinery, marine and other hydraulic systems.
