NEMO® SH Sanitary Pump

...the way to a sanitary solution!

General

Universal - NEMO® SH Sanitary Pump

The NEMO® SH Sanitary Pump is employed in the food products, pharmaceutical, cosmetic and chemical/biochemical industries for hygienic applications and optimal cleaning. It is ideal in these settings due in part to its continuous, pressure-stable, gentle and low-pulsation handling and in part to its capability of metering in proportion to speed. The design with bearing housing and free shaft ends enables you to choose any drive type.

Various regulatory agencies have set specifications for a sanitary 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® Sanitary and 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® SH Sanitary Pumps:

  • continuous low-pulsation handling unaffected by fluctuations in pressure and viscosity
  • capacity in proportion to rotation speed with precise metering over a broad rotational-speed range
  • high suction and pressure capability without valves
  • reversible pumping direction
  • stator with chamfered entrance for optimal filling of the conveying chamber

NEMO® SH Sanitary Pumps offer you:

  • gentle product handling
  • 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 sanitary joints for sticky products
  • elastomers approved for food products in accordance with FDA and BfR
  • horizontal and vertical installation
  • easy serviceability

Advantages of the NEMO® SH Sanitary Pump:

  • shaft seals suitable for food products with compression-proof bolted seal casing enable reversal of the direction of rotation, and so of the direction of conveyance, up to the maximum pump pressure
  • streamlined, crevice-free housing model prevents product settling
  • all product-contacting surfaces are polished to prevent build-up of the product and facilitate cleaning
  • the pump housing and stator can be optionally heated

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

Your edge – process stability even under great demands!


Technique

Our Design – Your Advantage: Easy Serviceability, Dependability, Operating Safety

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 appropriate. In addition, a thermal stator protector (STP) provides protection against overheating and dry running. Stator inlet with chamfered opening for improved feed into the pumping element.

3 Sanitary Joints
Patented open crevice-free sanitary joints for optimal cleaning.

4 Drive Train
Drive and connecting shaft with coupling rod and two sanitary joints for the transmission of power from the drive to the rotor.

5 Seal Casing
Shaft seals suitable for contact with food products, with compression-proof, bolted shaft seal housing, enable a reversal of the direction of rotation up to the maximum pumping pressure.

6 Protective Tubing for Stator
Made of stainless steel (optional).

7 With Bearing Housing and Free Shaft Ends
The design with bearing housing and free shaft ends enables you to choose any drive type.

The NEMO® SH Sanitary Pump is available …

  • in various sizes for flow rates up to 620 gpm
  • for differential pressures up to 350 psi
  • with optional tangential CIP supports on the pump housing and end supports
  • 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

… conveys …

  • sensitive substances under gentle, sanitary conditions

… and offers

  • a variety of shaft seals and construction types:

Shaft Seals

Single mechanical seal with elastomer bellows, with or without knife edges. Seal rings of SIC. Elastomer material also FDA-approved upon request.

Bi-directional, loaded

Single mechanical seal with capsuled corrugated spring. Smooth outer contour. Seal rings of SIC. FDA-approved elastomer material.

Bi-directional, unloaded

Optional Components

Conveying Screw and hopper Housing
For slowly flowing and pasty substances, the pump is optionally equipped with a conveying screw and hopper housing for optimal filling of the conveying chamber.

Heating Rail and Heating Jacket
Optional heatable or coolable design of the pump housing and of the stator

CIP/SIP Process
To achieve the velocity of flow necessary for cleaning fluid at a minimum of 1.5 m/s in the entire system in accordance with CIP procedures, NEMO® Sanitary and Aseptic 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.

Your edge – process stability even under great demands!
