24 series Hygienic Positive Displacement PumpThe 24 Series range of positive displacement rotary lobe pumps is a proven design spanning over 20 years. With thousands of pumps in use around the world users agree that it is one of the best designed hygienic pumps on the market today. The 316 Stainless Steel 24 Series pump range incorporates improved technology in hygienic pump design and manufacturing techniques, yet utilises the traditional tri-lobe rotor concept which is so well accepted by the world’s leading suppliers of Food, Personal Care and Chemical products.
Design and features• Adaptability - This is the key design concept. The pump utilises ‘bolt on’ features which allow quick and easy interchange of parts to enable exact specification of the pump to suit any application.......from stock!
• Rugged Design - The bearing frame design utilises large shaft diameters mounted in high specification taper roller bearings, fitted into rigid pillars which form an integral
part of the high grade alloy housing. These ensure maximum shaft stiffness in order to avoid premature pump failure due to overpressure or other abuse.
• Low Maintenance - The shaft, bearing and gear assemblies are fully immersed in an oil bath to give maximum life even at extremes of operating conditions. The timing gears are easily accessible at the rear of the pump in the unlikely event that re-timing should become necessary. Rotors are all fully interchangeable avoiding the need to re-time which is a problem associated with so many other rotary lobe and circumferential piston pumps.
• Improved Hygienic Technology - Fully swept pump chamber together with sealed rotor spline, accessible seals, and approved sealing components ensure that the pump meets the stringent requirements of major international customers
optionsSeals - Single mechanical seals are of hygienic design. Materials include carbon, stainless steel, tungsten carbide and silicon carbide.
Low pressure flushed seals utilise the same single mechanical seal with an additional housing. A low pressure flush liquid washes away crystallising products or liquids which ‘skin over’.
Double mechanical seals utilise all the components from single seals. For hazardous, toxic, highly abrasive or sterile products.
Gland packing - a cost effective general purpose seal for non-hazardous liquids. Used on either a stainless steel or hard chrome plated anti-wear sleeve.
O-Ring seals - another low cost seal option used primarily for self lubricating products such as dairy products.
• Certification - 3A Variants with Nitrile or EPDM elastomers and port options - Tri-clamp, IDF, 3A, DIN11851.
• Rotors - Tri-lobe rotors in stainless steel handle 90% of all applications. The traditional rotor shape gives an excellent combination of efficiency, solids handling, low and high viscous product capability.
Bi-lobe rotor in stainless steel for exceptional handling of delicate, soft solids such as fruit pieces and vegetables.
Rubber covered tri-lobe rotor to cope with small hard solids such as small bone fragments or ice crystals.
• Connections - All US and European standards including DIN, SMS, RJT, IDF, Tri-Clamp & BSP. Most pumps available with 2 different sizes, all fully interchangeable.
• Elastomers - Nitrile, Viton, EPDM, PTFE or Kalrez product contact joints are available.
• Other options - Pump head temperature control jackets. Integral pressure relief valve.
Enlarged suction ports for highly viscous product.

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.
TORNADO® advantages are small space requirements due to their compact design, high performance and maximised operational reliability, and the physical separation between the pump head and bearing housing. TORNADO® pumps are particularly service and maintenance friendly; all parts that come into contact with the media are directly accessible without dismantling the pipework or disconnecting the drive.
The TORNADO® rotary lobe pump is a positive displacement pump. The pumping action is generated by the contrarotation 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.

We have perfected the rotary lobe pump concept by incorporating the tried, tested and proven NETZSCH core competence in the design and manufacture of engineered rubber solutions for the new TORNADO® T2. During the entire pumping cycle only elastomer and metal component surfaces interface within the pump; elastomer to elastomer component surface interfaces, which suffer from excess wear and generate heat, are completely eliminated. Having these dissimilar materials for the static and dynamic pump head components, the elastomeric surfaces are subjected to a lower dynamic loading resulting in less plastic deformation and stress which in turn reduces wear and extends operational life. The use of high quality sealed for life bearings, selected for their load carrying characteristics and long life, combined with the tooth belt drive result in a drive train that can be considered maintenance-free.
efficiency in the smallest space
Smaller overall dimensions and the innovative design concept of incorporating a timing tooth belt to both synchronise and drive means reduced space is required for both installation and in place servicing representing a cost saving in terms of site utilisation.

The quality of the components makes the difference
Torsional strength and deflection-resistant high-quality shaft material combined with sealed for life high load characteristic angular contact ball bearings ensure axial and radial shaft stability maintaining pump head rotor fits and clearances resulting in predictable process stability.
Plastic deformation and heat generation is reduced by maintaining a uniform elastomeric wall thickness within the pump chamber. Material sections, bearing selection and seal positioning combine to minimize the adverse effects on dimensional changes to pump head geometry due to temperature changes.
The design and geometry of the rotors ensures a high level of durability. With the rotor fixing and drive outside of the pump chamber the rotors can have a completely flat continuous front and back face with no dead areas
“Full service in Place” instead of ”Maintenance in Place”
Servicing a rotary lobe pump has never been so easy and all 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. The geometry of the rotors means that they can be fitted and removed independently. There are no keys dictating a unique rotor position which results in faster,
which eliminates the possibility of fibrous material becoming trapped and compacted. The mechanical seal design and seal face position eliminates dead areas and allows constant circulation of the media around the faces which ensures that the risk of media entrapment and compaction is minimised.
The TORNADO® T2 all metal pumps can be manufactured from metals offering higher levels of cleanliness, corrosion or abrasion resistance and can therefore be applied to applications demanding the characteristics of these materials, especially in the low sanitary hygienic or chemical market sectors.
easier and cleaner rotor removal and replacement and for rotor synchronisation a setting device is included as an integral part of the pump front cover. Benefitting from all these features the service time for the TORNADO® T2 has been reduced to significantly less than half the time required for servicing a conventional rotary lobe pump. The pre-set cartridge mechanical seals are fitted directly into the rotor and mounted on the shafts as one assembly. There are various cartridge mechanical seals available all of which fit into a common housing allowing for seal upgrades without modification.
the first rotary lobe Pump with an elastomer liner reduces life cycle costs (lCC)
For the first time in a rotary lobe pump an elastomer liner is used for all media wetted surfaces of the pump chamber, which is both easy to replace in the event of servicing and significantly less expensive than replacing wear plates and housing parts.
By the correct and most appropriate choice of mating materials and the optimum sizing of the pump head interface geometry, especially with the rubber-metal pump, friction resulting in heat can be minimised. This results in both an energy saving and a longer life for consumable spare parts.
Maximum reliability through design, material and range of mechanical seals
The revolutionary NETZSCH PRS (Pulsation Reduction System) guarantees an almost pulsation-free discharge that is of benefit in many process applications. Even when used in conjunction with straight bi-lobe rotors, which ensures better solid handling capability and easier maintenance, the NETZSCH PRS provides an almost pulsation-free flow which outperforms the characteristics of complex multi-lobe helical rotors. The pump chamber and mechanical seal design and position eliminates dead areas, where pump media can collect and compact, making cleaning easier, either manually or by CIP.

Optimum choice of material – Your application is the decisive factor
Plastic deformation and heat generation is reduced by maintaining a uniform elastomeric wall thickness within the pump chamber. Material sections, bearing selection and seal positioning combine to minimize the adverse effects on dimensional changes to pump head geometry due to temperature changes. The design and geometry of the rotors ensures a high level of durability. With the rotor fixing and drive outside of the pump chamber the rotors can have a completely flat continuous front and back face with no dead areas which eliminates the possibility

our product philosophy – your benefit: the best pump foryour application
dry running protectorThe dry running protection units (STP2A, STP2D) for use with the Tornado rotary lobe pumps operate by monitoring the temperature between rotor and rotor case during normal operation. Should the operating temperature rise over a predetermined set point due to an increase in friction caused by dry running the unit will shut down the pump, thus preventing any damage to the rotor case liner and rotor. The unit controller can be set for two different switch temperatures, for example the first set temperature could be used for the normally pumped media and the second for a different media temperature, for example for a cleaning fluid process.
quench pot for single mechanical sealsA quench pot is necessary when the shaft seals need to be operated with a quench, but it is not required that the seal is continuously flushed. The provision of a quench pot would be recommended to prevent dry running of the seals or crystallisation of the pumped media.
Pressurised flush for double mechanical sealsA double mechanical seal must be used in conjunction with a system providing a pressurised flush or thermo-syphon system. The pressurised flush is required to lubricate the seals, cool the seals
and seal area and flush contaminants from the seal chamber. The flush liquid should be compatible with the pumped media, lubricating and have a high specific heat capacity. The pressure of the flush should be 2bar above the pressure acting on the inboard seal from the pump chamber and flow rate of the flush must also be controlled.
