Series 53 Axial Piston Pump from Rexroth

The new Rexroth Series 53 A10VO medium-duty axial piston variable pump (250/315 bar) combines functionality using electro-proportional controllers with robust control electronics. The new series 53, with its favorable power/weight ratio, is used as a pump for working hydraulics in open circuits.

According to Bosch Rexroth, this is the first time a pump of this power category can also be used for hydraulic-mechanical power control. The power controller prevents overloading the combustion engine. The electroproportional swivel angle adjustment allows precise flow control and electronic limit load control. The electrically-adjustable differential pressure control improves the resolution for fine control, such as for cylinder end-position damping.

The A10VO series 53 variable pump provides a starting point for developing intelligent, fully electrohydraulic system solutions such as Electrohydraulic Flow Matching (EFM). The Rexroth control electronics ensure a total volume flow determined by the requirements of the individual consumers. Bosch Rexroth claims this improves response characteristics and decreases the sensitivity to changes in disturbance variables. The implement hydraulics are more agile and less sensitive to vibration.
