Universally applicable – the 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 QHD (Qualified Hygienic Design). The materials used are approved by the FDA (Food and Drug Administration). 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).
Features of the NEMO® SH Plus Hygienic Pumps
- 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 hopper-shaped entrance for optimal filling of the conveying chamber
NEMO® SH Plus Hygienic Pumps offer you:
- flexible rod design for uncompromising hygiene and long service life
- gentle product conveyance
- long production cycles with contamination-proof, sterile pump construction
- CIP and SIP capability
- product admission under vacuum conditions up to almost an absolute vacuum
- open, patented hygienic joints for smearing media
- elastomers approved for foodstuffs in accordance with FDA and BfR
- horizontal and vertical installation
- easy serviceability
Advantages of the NEMO® SH Plus Hygienic Pump:
- 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 prevents sedimentation of the product
- all product-contacting surfaces are polished to prevent build-up of the medium and facilitate cleaning
- the pump housing and stator can be optionally heated
Take advantage of our decades of experience and know-how in the manufacturing of positive-displacement pumps.
Your edge – process stability even under great demands!
1 Rotor
In two geometries and with polished surfaces.
2 Stator with reduced walls
For changing temperatures, a patented stator with reduced elastomer wall thickness is used. In addition, a thermal stator protector (STP-2 or STP-D) provides protection against overheating and dry running. The stator inlet has a hopper-shaped opening for improved feed into the conveying chamber.
3 Drive chain
The all-purpose flexible rod used for the transfer of power from the drive to the rotor in the NEMO® SH Plus hygienic pump is corrosion-resistant as well as dead-space, wear- and maintenance-free, because no components move against each other as they do in joints. Neither lubricants nor seals are needed, so the lubricative properties of the pumped product need not even be taken into account. This is ideal for sensitive substances with or without suspended solids and for uncompromising hygiene.
4 Seal casing
Shaft seals suitable for contact with foodstuffs, with compression-proof, bolted shaft seal housing, enable a reversal of the direction of rotation up to the maximum pumping pressure.
5 Protective tubing for stator
Made of stainless steel (optional).
6 With bearing block and free shaft ends
The design with bearing block and free shaft ends enables the universal employment of any drive type.
