Sauer-Danfoss Series 90R 90L — hydraulic pump
Sauer-Danfoss Series 90R 90L is a line of swashplate axial piston hydraulic pumps with variable displacement from 55 to 250 cm³ for closed-circuit hydrostatic systems. The designation 90R indicates right-hand input shaft rotation, 90L indicates left-hand rotation. The pumps feature an integral gerotor-type charge pump to replenish the circuit and cool the fluid. The series supports a wide range of control options, including electrohydraulic controls compatible with PLUS+1 microcontrollers.
