Design with bearing housing and drive shaft allows for the use of all types of drives.
    • NEMO® SH Plus Hygienic Pump

    • The NEMO® SH Plus Hygienic Pump is employed for hygienic applications in the foodstuff, pharmaceutical, cosmetic and chemical/biochemical industries in order to provide continuous, pressure-stable, gentle and low-pulsation conveyance with optimal cleaning and dosing in proportion to speed.

      The design with bearing block and free shaft ends enables the universal employment of any drive type.
      Many different regulatory bodies have set specifications for a hygienically correct configuration of components and machines, as well as for component cleanability. NEMO PUMPS® are designed, produced and inspected in accordance with the regulations of the EHEDG (European Hygienic Equipment Design Group) and the QHD (Qualified Hygienic Design). The materials used are approved by the FDA (Food and Drug Administration) and the BfR (German Federal Institute for Risk Assessment). In addition, NEMO® Hygienic and Aseptic Eccentric Screw Pumps meet the specifications of the United States’ 3-A Sanitary Standards and are GOST-R certified (a Russian certificate of conformity).
    • The multipurpose solution

    • The pumps are specifically used for products with the following characteristics:
      • Low to high viscosity
      • Shear-sensitive
      • High solids content (such as fruit pulp and stone fruit)
      • Free of solid

      The strength of the mobile NEMO® beverage pump is the universal use in wine-growing, wine production, sweet must production, breweries, distilleries and in beverage and juice production.

    • Dependable conveyance with no overflow

    • In some cases the viscosity of the crude oil is so high, that it cannot be conveyed by a horizontally installed pump. Here the vertically designed NETZSCH progressing cavity pump offers an ideal solution. This design is also available as a Caisson pump and is characterized by extremely low NPSH values.
  • NEMO® Immersible Pumps

  • NEMO® semi-submersible pumps are used for emptying barrels, containers, tanks, clarifi ers, pits, etc. They are also used where space is limited and when cavitation may be a danger or where low NPSH is available. Furthermore the pumps are suitable for emptying barrels containing materials harmful to water and the environment where emptying through a connection at the bottom of the barrel is not permitted.

    Performance
    Capacities up to 140 m3/h (620 gpm). Pressures up to 24 bar (340 psi). Depending on the application a number of designs/immersion variations are available. The immersion depth is adjusted as required by the application.

    Description
    Compact design with directly flanged drive. Four rotor/stator geometries for optimal performance. Immersion depth up to 10 m. The length of the immersed tube can be modified by using an extended pump housing or anadditional suction pipe or a combination of both.
    • NEMO® Immersible Pump BT with integral Mounting Plate

    • This pump is used in closed pits, tanks and containers where there is the possibility to vertically flange mount the pump to the tank lid. Depending on pump size, speed and immersion depth up to 10 m, an additional support guide is available to secure the pump to the bottom or to the wall near the bottom. Removal of the pump from a full tank is possible because the guide units are  self-centering and secure the pump suction without fixings. The pump with discharge connection below the mounting position the discharge connection of the pump is below the tank lid. The product is either piped to the outside vertically through the lid via a 90 ° elbow or horizontally through the tank wall. This minimize  the dead space in the pump housing thus reducing the overall height of the pump above the tank lid. This version is normally used where there is only limited space available.
    • NEMO® Immersible Pump BT with Suspension Bracket

    • This pump is used for emptying open barrels and containers. It is equipped with a suspension bow for crane suspension. Immersion depth up to 3 m.
  • TORNADO® Rotary Lobe Pumps

  • 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.

    Broad Application Spectrum
    TORNADO® rotary lobe pumps can be used for media that has the following characteristics:
    • Abrasive, corrosive and fibrous
    • Containing solids (max. particle size up to 70 mm)
    • Low to high viscosity
    • Shear sensitive
    • Non-lubricating and lubricating
    • Stability

    • The best maintenance is no maintenance
      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.

      Compactness - Efficiency in the smallest space
      Smaller overall dimensions and the innovative design concept of incorpo¬rating 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.
    • High Performance, Reliability, Maintenance in Place

    • Stability – The best maintenance is no maintenance

      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 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.
    • Ease of Service

    • "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, easier and cleanerrotor 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.
    • Ease of Service

    • 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.

  • Type of Joints The Proper NEMO® Joint for Every Application

    • B Universal Pin Joint

    • The NEMO® universal pin joint is the standard joint for NEMO® industrial pumps because of its simple design and outstanding reliability. To achieve a long service life, the joint is oil fi led and sealed by the NEMO® SM® seal. The joint can also be used without seal in case of extremely high temperatures and products where elastomers are not suitable. The joint consists of a minimum number of parts that enables simple dismantling for maintenance.
    • V Pin Joint

    • The operational characteristics of the NEMO® V pin joint are similar to those of the B pin joint. For longer service life in difficult applications they are strengthened by hardened bushings fitted into boreholes in the coupling rod and the rotor/drive shaft head. The Vpin joints with hardened bushes are easy to remove for maintenance purposes. Standard on the 125 pump size.
    • H Hygienic Pin Joint

    • The open, patented pin joint was designed
      specifically for use in hygienic pumps. It is crevice and dead space free, polished and, therefore, easy to clean. The joint is made in accordance with US 3-A Sanitary Standards.
    • F NEMO® Flextec Flexible Rod

    • The flexible rod is wear- and maintenance free
      because there are no components moving against each other as in other joint types. Neither lubrication nor seals are required. Therefore, the flexible rod is suitable for high pressures and temperatures. The
      flexible rod is also free from crevices and dead spaces which allows it to be used for pumping highly sensitive products in aseptic conditions. It is designed in accordance with the US 3-A Sanitary Standards.
    • K Joint

    • The patented K joint was designed for extremely arduous industrial applications involving constant pump running, frequent stop/starts or shock loads. It is kinematically designed so that the torque and axial loads are borne by separate elements within the joint. The joint is oil fi lled and hermetically sealed by two seals which are resistant (compatible) against the lubricant and the pumped product. Filling the space between the two seals with oil allows the use of the joints at pressures up to 12 bar (170 psi).
    • Z Double Seal Pivot Joint

    • For the largest flows and pressures possible with NEMO® pumps where the torques and axial loads are at their highest (in bearing housing size NM 125SY and above) the pumps are fitted as standard with a cartridge type precision pivot joint. The joint is oil filled, hermetically sealed by two seals which are resistant (compatible) against the lubricant and the pumped product. It is suitable for continuous operation.
