Pump units

For the decanter scroll drive system

The pump unit uses an electric motor to drive a hydraulic pump. Oil flowing from this pump through a control block controls the oil flow to the ROTODIFF.

Pump units

Using three different control systems, depending on the requirements:

VFD control / Automatic, analogue control with frequency converter and electronic unit
B/C control / Automatic, analogue control with electronic unit
C control / Automatic, analogue control, hydraulic

Pump units

Electronic display and control units

To control VISCOTHERM drives

Viscotherm AG designs and builds electronic display and control units. This enables continuous and automated control of VISCOTHERM drives and simplifies the entire process of separation.

Technology for stringent requirements

“Drastically reduced energy consumption thanks to the hydrostatic ROTODIFF drive in the dynamic test bench.”

Viscotherm ROTODIFF drives are used in energy-efficient dynamic test benches. As the heart of  dynamic test benches, for gear units, couplings and gears in closed circuits, ROTODIFF drives guarantee that the energy consumption is drastically reduced.

Helicopter manufacturers around the world rely on Viscotherm technology to test the stringent requirements related to quality, reproducibility and the safety of mechanical drive systems.
