DV Hydraulics carried out a retrofit of a 10,000-ton press with an advanced servo pump system. Originally built with a conventional hydraulic system, this press was upgraded in 2013 by DV Hydraulics to an energy-efficient installation featuring servo pumps.

The project included not only the hydraulic upgrade but also the complete control system and safety features around the press, including loading and unloading, and pre- and post-press checks.

The result: a powerful, precise, and reliable solution that meets the highest industrial standards. The press operates in two quadrants and uses a servo pump system for highly efficient drive performance. This retrofit is a prime example of innovation and sustainability in heavy industry, particularly in control and safety.

Main specifications of the press:

• Press force: 10,000 tons

• Number of cylinders: 2 units, bore 1,215 mm – stroke 630 mm

• Synchronization: servo pump control, accuracy < 0.05 mm

• Closing speed: 400 mm per minute

• Existing frame: reused

Main specifications of the hydraulic installation:

• Operating pressure: 450 bar

• Maximum flow for opening/closing: 1,000 liters per minute

• Medium: Hydraulic oil VG46

• Servo pump system: DV Hydraulics’ first servo pump project (2013)

• Control: Closed-loop for synchronization and speed

• Energy efficiency: Retrofit to servo pump technology – significant energy reduction

Control system specifications:

• Complete control and safety: Siemens components

• PLC: Siemens S7 series

• Functions: Loading and unloading, pre- and post-press checks

• Safety: Integrated safety logic

This retrofit combines power, precision, and energy efficiency in one solution.

Thanks to servo pump technology and Siemens control, this system is ideal for demanding industrial applications where reliability and accuracy are critical.
