What are the benefits of servo pump control?
In times of increased prices, one aspect is particularly important in plant and machine manufacturing: efficiency. Against this background, the servo pump solution from KEB enables shorter cycle times and pump sizes thanks to the system-specific options of the multi-hydraulic selector. The energy-efficient operation of a system such as an injection moulding machine not only makes ecological sense, but is now more important than ever for cost reasons. Servo pump control from KEB in combination with the right servomotors provides a solution.
Conventional hydraulic systems are operated directly from the electrical mains. Due to the uncontrolled operation, constant pressure and constant flow prevail. The inability to influence these parameters leads to high energy consumption. The use of servo pump control from KEB ensures that energy is only supplied to the system when it is actually needed. The result: energy consumption can be reduced by up to 70 per cent. And there are even more effects from which you benefit:
- Reduced cycle time and pump size
- Lower energy consumption, reduce costs
- Up to 20 dB (A) quieter: Less noise emissions because motor only runs when needed
- Fewer components in the system
- Less maintenance required
- Longer service life of your machine due to lower heat generation
- More productivity thanks to increased machine availability

Application Automation and Drives
How does our servo pump solution work?
A servo pump system usually consists of a gear pump, servo motor and frequency inverter. The KEB solution for servo pump control is located in exactly this inverter: The integrated software in our tried-and-tested COMIVERT F6 and S6 drive controllers has an algorithm with which the flow and pressure of the servo pump can be controlled and regulated highly efficiently. Adaptability to the machine requirements is a major advantage for injection moulding machines, for example, as cycle times are particularly relevant here. Pump protection is realised through corresponding software features and parameters.
KEB Automation provides you with system solutions comprising controller, inverter and motor from a single source for your application. One example: The interaction of KEB drive controllers with servo pump control and our servo motors from the DL4 series achieves particularly high dynamics. A powerful combination that also saves energy. Commissioning of the system is simplified by a wizard for guided parameterisation of the application and the auto-tuning function (calibration to the hydraulic circuit). The adjustment of the pump speed in the partial load range and outside the operating cycle, in combination with volume flow or pressure control directly via the pump system, ensures economical implementation of your hydraulic machines.
