Machine module servo pump

Efficient machine solution for hydraulic and hybrid machines

Baumüller supplies innovative and optimized drive solutions for all sectors through years of intensive cooperation with mechanical engineers. Due to the integrated control unit in the converter, Baumüller servo pumps can easily be connected to your machine control systems. In the process, they reduce the energy consumption of your drive system significantly and also allow for shorter cycle times, greater accuracy as well as lower noise development. See for yourself and rely on the flexibility and power of innovation of the experts from Baumüller.

Hydraulics vs. Servo-hydraulics
Calculate your savings!

The Software – intelligence in the drive

The servo-hydraulic technology module is integrated directly in the servo drive and is fundamentally responsible for ensuring maximum utilization of the advantages of servo-hydraulics. The heart of the software is the flexible pressure and flow rate control in a controller cycle time of only 125 µs for maximum dynamics and precision. Thanks to intelligent feed forward pressure controls, the control adapts itself to different hydraulic ranges and thus achieves outstanding pressure adjustment behavior.

Parameterization of the servo drive including servo-hydraulic functions is fully embedded in the ProDrive user interface. The guided commissioning makes fast commissioning possible, even without in-depth programming knowledge or detailed servo drive technology know-how. The graphic user interface screens enable logical and clear operation.

The commissioning and optimization can also be undertaken as a service by the Baumüller experts, who have many years of experience in the application of servo-hydraulics systems and thus integrate the system into the machine optimally.

In addition to the excellent control behavior and easy handling, the latest Baumüller V2+ software for servo-hydraulic systems also includes numerous protection and monitoring functions that further enhance the performance and reliability of the system.

NEW: Controlled shutdown of the servo hydraulics

Error case:

  • Detection of faulty states in the hydraulic system
  • Monitoring of the pressure build-up time
  • Error message with definable error response


  • High availability: Protection of the pump against dry running

Thermal pump protection

Error case:
  • Thermal pump overload in case of overlong pressure maintenance mode (zero flow)
  • Wear and possible premature failure of the pump
  • Protection of the pump against thermal overload without temperature sensor
  • Calculation of the pump thermal overload depending on process parameters (pressure, speed, etc.)
  • Optional: Activation of a hydraulic bypass on reaching a definable warning threshold to relieve the pump
  • Error message with definable error response


  • Increase in availability: Protection against pump failures caused by thermal overload
