The technology of the rotary lobe pump

Rotary lobe pumps are self-priming, valveless and rotating positive displacement pumps with two rotary lobes running in a mesh. The rotation of the rotors creates a vacuum on the suction side, which draws in the pumped medium. The rotors displace the medium into the pressure area. Two to six-room fillings are substituted per rotation, depending on the number of rotor blades. This enables dosing proportional to rotation speed. Due to the unique spatial separation between pump and gear chamber, TORNADO® rotary lobe pumps also offer you maximum operational reliability. With rotary lobe pumps, you can pump both low and high viscosity media. Due to the significant free ball passage and the low speeds, they are insensitive to blockages, clogging and foreign bodies. Varying solids contents have just as little influence on the flow rate as pressure changes. This enables continuous and powerful pumping.

Product range of the TORNADO® rotary lobe pumps

TORNADO® T.Envi® Rotary Lobe Pump

The TORNADO® T.Envi® rotary lobe pumps in FSIP® design are optimally adapted to your requirements in environmental and biogas technology and impress with easy maintenance.

TORNADO® T.Sano® Rotary Lobe Pump in Smooth Surface

The innovative design of the TORNADO® T.Sano® rotary lobe pump in Smooth Surface has a completely smooth housing in comparison to the standard T.Sano®, which attracts barely any dirt or dust. The whole T.Sano® series are EHEDG-certified.

TORNADO® T1 Rotary Lobe Pump

The TORNADO® T1 rotary lobe pump with its proven quality is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.

TORNADO® T.Sano® All-Metal Rotary Lobe Pump

The TORNADO® rotary lobe pumps in all-metal version are primarily used in the chemical and food industry. These pumps are suitable for sensitive and aggressive media as well as media with high hygienic requirements. 

The NETZSCH TORNADO® Mobile

A TORNADO® rotary lobe pump fastened onto a mobile base – this is the NETZSCH TORNADO® Mobile. The concept of mounting the equipment onto a car or truck trailer makes it possible to pump large quantities of fluids with solid content, wastewater and slurries at the most unusual of sites.

TORNADO® T.Proc® Rotary Lobe Pump

The wear-resistant TORNADO® T.Proc® rotary lobe pump in FSIP® (Full Service in Place) design is available in both all-metal and metal-elastomer versions.
