NETZSCH Pumpen & Systeme GmbH has introduced TORNADO® T2 rotary lobe pump aiming to increase reliability, maintenance and performance while reducing the total cost of ownership
Self-priming and valve-less, the TORNADO® T2 is a positive displacement pump ideal for any kind of liquid, including media containing gas, solids or fibrous matter. The TORNADO T2 pump can be used in intermittent, continuous or metering applications.
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.
The pump features an elastomer insert design that saves energy, reduces wear and increases overall service life. 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, where thick elastomer packages on the lobes are in constant kneading contact.
The 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 the required weight and installation space. Since the drive requires no lubrication, the chance of oil leaks is completely eliminated.
The TORNADO T2 features the FSIP™ (full service in place) design, which aims to improve access for inspection, cleaning, service and replacing parts. 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.
