Rexroth A2FO Axial Piston Fixed Pump - Series 61 is suitable for both mobile and fixed applications, designed for hydrostatic drives in an open circuit. With an axially tapered piston rotary group, it has a fixed pump in a compact bent-axis configuration. Some of Agricultural Machinery, Construction Equipment, Material Handling, Industrial Presses, Mining Machinery, Marine Applications etc.

Effective operation is made possible by the pump's flow rate, which is directly proportional to the drive speed and displacement. It is constructed with robust drive shaft bearings to match the standard service life requirements of different industries.

The compact size and great power density of this pump contribute to its overall excellent efficiency. One piece tapered piston with piston rings for dependable sealing is part of its low-cost design. Rexroth A2FO Pump Series- 61 comes in multiple sizes with pressures ranging from 315/350 bar for size 5, 400/450 bar for sizes 10 to 200, and 350/400 bar for sizes 250 to 1000, all for open circuit applications.

1)	These values are valid at: – an absolute pressure of pabs = 1 bar at suction port S – for the optimum viscosity range from vopt = 36 to 16 mm2/s – with hydraulic fluid based on mineral oils
2)	Maximum speed (limiting speed) with increased inlet pressure pabs at suction port S, see the following diagram.
3)	Torque without radial force, with radial force see table “Permissible radial and axial forces of the drive shafts”
