NEMO® SA Aseptic Pump

The NEMO® SA aseptic pump with bearing housing with a maintenance-free flexible rod is crevice free and used, because of its cleanability (CIP/SIP process), for aseptic and hygienic applications in the food, pharmaceutical, cosmetic and chemical/biochemical industries for continuous, pressure-stable, gentle and low-pulsation conveyance as well as dosing in proportion to speed.

Description of NEMO SA Aseptic Pump

The NEMO SA Aseptic Pump is employed for aseptic and hygienic applications in the foodstuff, pharmaceutical,
cosmetic and chemical/biochemical industries in order to provide continuous, pressure-stable, gentle and lowpulsation conveyance and dosing in proportion to speed. To avoid contamination from the environment, all hermetic
areas can be sealed with steam or sterile condensate. 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 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) and the BfR (German Federal Institute for Risk Assessment). In addition, NEMO
Aseptic Pumps meet the specifications.

Advantages of the NEMO SA Aseptic Pump:

  • all hermetic areas are double-layered and sealed
  • foodstuff-suitable shaft seals with compression-proof bolted seal casing enable reversal of the direction of rotation
  • and thereby also of the direction of conveyance, up to the maximum pump pressure
  • streamlined, crevice-free housing model with reduced diameter prevents sedimentation of the product
  • all product-contacting surfaces are polished to prevent build-up of the medium and facilitate cleaning

Features of the NEMO SA Aseptic Pump

  • perfectly crevice-free pumping space
  • optimized flow through the pump
  • continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity
  • conveyance volume in proportion to rotation speed with high dosing precision over a broad rotational-speed range
  • high suction and pressure capability without valves
  • reversible conveyance direction
  • stator with funnel-shaped entrance for optimal filling of the conveying chamber

The maximum flow rate of the pump depends on the specific model and size, but it can range from 50 to 5000 liters per hour.

The pump is designed for use with low to high viscosity fluids, such as slurries, pastes, and liquids containing solids or fibers. It can also handle shear-sensitive and abrasive materials. The materials must be compatible with the pump’s wetted parts, which are typically made of stainless steel.

The maximum pressure that the pump can generate depends on the specific model and size, but it can range from 6 to 15 bar.

Yes, the pump can be cleaned and sterilized in place using standard CIP and SIP procedures. The pump’s design allows for easy disassembly and reassembly for cleaning and maintenance purposes.
