tornado® rotary lobe pumps
the service-friendly rotary lobe pump, constructed according to the principle 'full service in place'

Maximum service friendliness meets high performance

netzsch tornado® self-priming, valveless, positive displacement pumps can be optimally customised to meet specific process and application requirements. they can be used for almost any media on intermittent, continuous or dosing applications.

• Compact design
• High performance
• Maximized operational reliability
• Physical separation between the pump head and bearing housing

Functioning principle

The tornado® rotary lobe pump 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.

Characteristics

• Valve-free construction
• Self-priming
• Suitable for any kind of liquid including media containing gas
• Handles shear sensitive fluids
• Operating at temperatures up to 100°c
• Reversible operation
• Can be serviced without disconnecting pipework
• Tolerance of dry running

The newly developed tornado® t2

Reliability: 'The best maintenance is no maintenance' - perfected the rotary lobe pump concept by incorporating the tried, tested and proven netzsch core competence in engineered rubber solutions for the new tornado® t2.

Process optimisation

Compactness - 'Efficiency in the smallest space': the innovative design concept of incorporating a timing belt to synchronise and drive the pump means reduced space. the smaller overall dimensions and maintenance in place represent a cost saving in terms of site utilisation.

Ease of service

'Full service in place instead of maintenance in place': servicing a rotary lobe pump has never been so easy without the need for any special tools. the rotors can be removed and replaced very easily and quickly because they are not bolted or keyed to the shafts within the pump head but fixed with quick-fit non-media wetted taper lock assemblies positioned and accessed outside of the pump head.

Environmental awareness

'Green is already our corporate colour': the weight of the tornado® t2 has been significantly reduced through the choice of materials and innovative component design. this also means the pump consumes less energy.

Drive options

A range of drive options are available to suit specific application and process requirements.

Optimum choice of material

Your application is the decisive factor! materials offering higher levels of cleanliness, corrosion, or abrasion resistance can be selected.

Mechanical Seal Selection for tornado® t2

A pump is only as reliable as its seals. therefore a range of seals and seal materials are available for the new tornado® t2.

The conventional tornado® t1

For more than 20 years we have been supplying the classic design netzsch tornado® t1 rotary lobe pumps. their extensive use demonstrates their high performance. the design is based on netzsch's decades of experience and development in positive displacement pumps.
