Drives for decanter centrifuges

Used for ecology

“Increased decanter power and improved separation results thanks to the hydrostatic ROTODIFF drive.”

For over 45 years, Viscotherm AG has continued to develop separation technology with ROTODIFF decanter centrifuge drives through continuous innovation. One of the main features is the optimal ease of adaptation to a wide variety of operating conditions.

Application examples: Waste water treatment plants / Chemical industry / Food industry / Drilling technology / Bio fuels / Environmental technology, mobile equipment / General industry

Viscotherm AG hydraulic motors

Swiss Quality – thousands of drive systems in operation worldwide!

Hydraulic solid bowl – scroll centrifuge drives from Viscotherm offer significant advantages. This is particularly true of products that are difficult to process, such as meat-and-bone meal, fish meal, casein, lactose, starch, PVC, cellulose derivatives etc. These products have a tendency towards vibration or adhesion (chatter). The service life of a ROTODIFF drive is many times longer than that of a gear unit. This is fully applicable in potentially explosive atmospheres thanks to ATEX certification.

VISCOTHERM develops and produces hydraulic ROTODIFF drive systems for a wide variety of applications. The drive systems are designed based on the required torque (ROTODIFF) and required differential speed (pump unit).

Over 5000 drive systems in use worldwide!
