Netzsch highlights ‘revolutionary’ new pump

Since the drive requires no lubrication, the chance of oil leaks is completely eliminated.

Netzsch claims that its recently released Tornado T2 rotary lobe pump increases reliability, maintenance and performance while reducing the total cost of ownership.

Tornado T2 is a self-priming and valve-less positive displacement pump ideal for media containing gas, solids or fibrous matter. It can be used in intermittent, continuous or metering applications.

What makes the Tornado T2 unique?

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

An elastomer insert design saves energy, reduces wear and increases the overall service life of the pump. Vulcanised onto the edges of the lobes to create a permanent hard-soft contact between the lobes throughout the 360° rotation cycle, the inserts avoid high-wear contact. The elastomer cage acts as a stator and is subject to less dynamic load and deformation than a traditional rotary lobe pump design, according to Netzsch.

Keeping it simple

Netzsch’s Tornado T2 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. Netzsch explains that because the drive requires no lubrication, the chance of oil leaks is completely eliminated.

The Tornado T2 is built around Netzsch’s unique FSIP (full service in place) design, which improves access for inspection, cleaning and replacing parts. Access to the pump’s chamber is possible by simply removing the positive displacement pump’s cover plate. The rotors can be removed and replaced easily and quickly because they are not bolted or keyed to the shafts inside the pump head. Their geometry meanwhile, means the rotors can be removed independently without the need for special tools. 

Since the drive requires no lubrication, the chance of oil leaks is completely eliminated.
