Viscotherm AG products

The ROTODIFF hydrostatic scroll drive is a radial roller piston motor capable of high torque, which is mounted directly on the bowl system, where the housing (stator) is flanged onto the bowl and the rotor directly drives the scroll. The hydrostatic transfer seal coupling enables operation of the scroll drive that covers the turned part. The ROTODIFF with a constant displacement drives the scroll at the differential speed required for the separation process based on the load. This ensures a continuously optimal output.

A solid bowl decanter centrifuge is used for a wide variety of procedural tasks, from treatment and separation to screening, concentrating, washing and extraction. The decanter drive is one of the most important prerequisites for an optimal separation process.

The ROTODIFF hydraulic motor is a high-torque radial piston motor which controls the differential speed between the bowl and scroll. The ROTODIFF hydraulic drive replaces the gear. The housing of the hydraulic motor is connected to the bowl and, as a result, rotates at the bowl speed. The drive unit, rotor (3) drives the scroll directly and, as a result, only rotates slowly at the differential speed.
