NETZSCH announces revolutionary TORNADO T2 rotary lobe pump

Posted: Thursday 8th December 2016

Redesigned to increase reliability, maintenance and performance, while reducing total cost of ownership.

NETZSCH Pumps North America, LLC, experts in solutions designed specifically for difficult pumping applications, announces that its innovative TORNADO T2 rotary lobe pump has been newly redesigned by its global parent company NETZSCH Pumpen & Systeme GmbH, headquartered in Germany. Self-priming and valve-less, the new TORNADO T2 is a positive displacement pump ideal for any kind of liquid, including media containing gas, solids or fibrous matter. Completely redesigned to increase reliability, maintenance, and performance, while reducing the total cost of ownership, the TORNADO T2 pump can be used in intermittent, continuous or metering applications.

Unlike conventional rotary lobe pumps that use standard elastomer lobes, the redesigned TORNADO T2 uses two hardened steel lobes that rotate in a geometrically adapted elastomer insert. This bi-lobe rotor design creates a considerably longer housing sealing line, providing more wear padding. A specially developed pulsation reduction system ensures minimal pulsation or shear forces.

The new pump features an elastomer insert design that saves energy, reduces wear, and increases overall service life. Vulcanized onto the edges of the lobes to create a permanent hard-soft contact between the lobes throughout the 360o rotation cycle, the insert avoids high-wear contact between elastomer parts. The insert acts as a stator and is subject to less dynamic load and deformation than a traditional rotary lobe pump design.

The new pump design also replaces complex timing gear with a robust synchronous toothed belt drive system. The drive greatly reduces the danger of transmission damage and also decreases required weight and installation space. Since the drive requires no lubrication, the chance of oil leaks is completely eliminated.

The TORNADO T2 features the innovative FSIP (full service in place) design, which improves access for inspection, cleaning, service, and replacing parts. Simply removing the cover plate on the TORNADO T2 allows quick and easy access to the pump chamber. The rotors can be removed and replaced easily and quickly because they are not bolted or keyed to the shafts inside the pump head. The rotors' geometry allows their independent removal without the need for special tools.
