Universally applicable - the NETZSCH TORNADO® Mobile

Rotary lobe pump on wheels for universal use at the most unusual of locations

The TORNADO® Mobile combines the flexibility and independence of a mobile unit with the proven technology of a TORNADO® T1 rotary lobe pump from NETZSCH. Mobility through mounting on a car or truck trailer enables the pumping of large quantities of fluids with high solid content, wastewater and slurry at the most diverse and unusual locations. Depending on the application, the TORNADO® rotary lobe pump is mounted on a trailer with diesel unit in the appropriate size.

At the core of the mobile units are the TORNADO® pumps with two rotary lobes which are three-winged and screw-shaped and engage whilst rotating. They thereby generate a vacuum on the suction side. This means the water is drawn in automatically andconveyed to the discharge side. Viscosity and dry matter content have a minimal effect on the volumetric flow. Solids like sand or clumps of earth pose absolutely no problems for the robust pumps. Robust design ensures reliable operation. When designing the pumps, special attention was paid to robustness to ensure that abrasive or aggressive media would be unable to damage the technology. The rotary lobes are coated with resistant nitrile rubber, which enables the pump seal to do its job reliably even under great stress and strain. Furthermore, the gear box and pump chambers in the pumps are separated from one another. Even in the event of the shaft sealing failing, the media being conveyed will not be able to get into the gear box and damage it. The pumping capacity, drive (diesel unit) and chassis are designed precisely to the features of the pumping medium and purpose. Highly diverse material and shaft seal variants cover virtually all applications in the areas of farming, environmental and catastrophe protection, chemical, paper as well as oil and gas. The TORNADO® rotary lobe pump is designed for easy handling and maintenance. In this way, any maintenance can be performed directly on site. In order to clean or replace seals or rotary lobes, for example, only the housing cover has to be removed. This ensures that the pump is quickly ready for use again.

TORNADO T1 Rotary Lobe Pump with labelling

1 Front Cover
Rotors, cover seal and product seals can be accessed for inspection, service or replacement by simply removing the front cover. Disassembly of the inlet and outlet pipework and pump housing is not necessary.

2 Wear Plates
Abrasion and chemically resistant, replaceable wear plates are fitted both sides of the rotors.

3 Rotors
Straight sided or helical rotors are selected to suit individual application requirements. Rotors are available as bi-lobe, tri-lobe or four-lobe and a wide range of materials is available. The rotor geometry and material are selected for the characteristics of the pumped media. Geometries are available for products which are viscous, abrasive or contain solids. Materials tailored to the media characteristics increase the durability of the rotors and extend service life.

4 Housing Crescents
Modular construction allows for the crescents to be simply replaced should wear occur. Pump life time can be further extended with the option of replaceable crescent liners.

5 Seals
Wide range of product seals and materials are available, which are selected to suit individual application requirements. Seal arrangements include easy access connections for seal quench or flush.

6 Gearbox
The patented gearbox design includes NETZSCH GSS-Technology separating the pump head from the gear box which eliminates cross contamination between the pump media and gear box lubricant.
