NEMO® SA Aseptic Pump

Your partner in perfectly sterile product handling!

General

The NEMO® SA Aseptic Pump is employed for aseptic and sanitary applications in the food, pharmaceutical, cosmetic and chemical/biochemical industries.  It provides continuous, pressure-stable, gentle and low-pulsation handling and metering. To avoid contamination from the environment, all hermetic areas can be sealed with steam or sterile condensate. The design, with bearing housing and free shaft ends, enables you to use any drive type.

Various regulatory agencies have set specifications for sanitary configurations of components and machines, as well as for component cleanability. NEMO® Aseptic 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). In addition, NEMO® Aseptic Pumps meet the 3-A Sanitary Standards specifications of the United States and are GOST-R certified (a Russian certificate of conformity).

Features of the NEMO® SA Aseptic Pump

  • crevice-free pumping space
  • optimized flow through the pump
  • continuous low-pulsation handling unaffected by fluctuations in pressure and viscosity
  • capacity in proportion to rotation speed with precision metering over a wide speed range
  • high suction and pressure capability without valves
  • reversible pumping direction
  • stator with chamfered entrance for optimal filling of the conveying chamber

NEMO® SA Aseptic Pumps offer you:

  • product handling under aseptic conditions
  • flexible rod design for uncompromising cleanliness and long service life
  • gentle product handling

  • easy serviceability

Advantages of the NEMO® SA Aseptic Pump:

  • all sealed areas are double-layered and sealed
  • sanitary shaft seals with compression-proof bolted seal casing enable reversal of the direction of rotation and so pumping direction, up to the maximum pump pressure
  • streamlined, crevice-free housing model with reduced diameter prevents product settling
  • all product-contacting surfaces are polished to prevent build-up of the product and facilitate cleaning

Take advantage of our decades of experience and expertise in positive displacement pump manufacture.

Shaft Seal:
Double mechanical seals arranged in tandem with depressurized static or dynamic quench. Seal rings of SIC. FDA-approved elastomer material. The configuration of the rotating unit guarantees air-tightness under changing temperatures and pressures. The seals are in accordance with the regulations of the EHEDG (European Hygienic Equipment Design Group) and the QHD (Qualified Hygienic Design).

The NEMO® SA Aseptic Eccentric Screw Pump is available…

  • in various sizes for flow rates up to 620 gpm
  • for differential pressures up to 350 psi
  • with stators and gaskets with various elastomers approved for contact with food products.
  • with stators with reduced walls
  • with S & L Geometry for optimal adjustment to the application

CIP/SIP Process
To achieve the velocity of flow necessary for the cleaning fluid of at least 1.5 m/s in the entire system in accordance with CIP procedures, NEMO® Hygienic and Aseptic Eccentric Screw Pumps are equipped with additional flushing supports in tangential configuration and must be equipped with a bypass line. The bypass is also necessary for the SIP process. The NEMO® Pump operates in a synchronized fashion both for the CIP and for the SIP process.

With tangential flushing supports, complete evacuation of the NEMO® pump is guaranteed. All pump materials are suitable for CIP and SIP processes.
