Features

–

Variable pump in axial piston swashplate design for

hydrostatic drives in an open circuit

– The flow is proportional to the drive speed and the displace-ment. The flow can be steplessly varied by adjusting the swashplate angle.

– Stable storage for long service life– High permissible drive speed

– Favorable power-to-weight ratio - compact dimensions– Low noise

– Excellent suction characteristics

– Axial and radial load capacity of drive shaft– Pressure and flow control– Electro-hydraulic pressure control– Power control

– Electro-proportional swivel angle control– Short response times

EK – Electro-proportional control with controller cut-off 17

Series 52 units are delivered as standard with 3.66 in3 (60 cm3). Higher values on request.2) Series 53 only with D flange3) Series 52 only with C flange4) See RE 92709

5) The following must be taken into account during project planning:

Excessive current levels (I > 1200 mA with 12 V or I > 600 mA with 24 V) to the ER solenoid can result in undesired increase of pressure which can lead to pump or system damage: - Use Imax current limiter solenoids.

- An intermediate plate pressure controller can be used to protect the pump in the event of overflow.

An accessory kit with intermediate plate pressure controller can be ordered from Bosch Rexroth under part number R902490825.
