NEMO® BH Hygienic Pump in compact block design

NEMO® BH Sanitary Pump in Compact Block Design

Solution for applications in the food, pharmaceutical, cosmetic and chemical industry

The NEMO® BH Sanitary Pump is employed in the food products, pharmaceutical, cosmetic and chemical/biochemical industries for sanitary applications and optimal cleaning. The important capabilities include, the continuous, pressure-stable, gentle and low-pulsation pumping and metering in proportion to speed. The block pump construction with flanged drive is particularly compact and economical to operate.

Various different regulatory bodies have set specifications for a hygienically correct configuration of components and machines, as well as for component cleanability.  The materials used are approved by the FDA (Food and Drug Administration) as well as EU-VO 1935/2004. In addition, NEMO® Hygienic and Aseptic 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® BH Sanitary Pumps:

  • continuous low-pulsation pumping unaffected by fluctuations in pressure and viscosity
  • capacity in proportion to rotation speed with high metering precision 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® BH Sanitary Pumps offer you:

  • gentle product handling
  • long production cycles with contamination-proof, sterile pump construction
  • CIP and SIP capability
  • product handling under vacuum conditions up to almost an absolute vacuum
  • open, patented sanitary joints for sticky products
  • elastomers approved for food products in accordance to FDA
  • horizontal and vertical installation
  • easy serviceability

Advantages of the NEMO® BH Sanitary Pump:

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

NEMO® BH Hygienic Pump

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 conveying chamber.

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 power transmission 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 Block Construction
The drive is flanged directly to the pump skirt, lending the system compact dimensions, a low total weight, constant axial height independent of the construction and size of the drive, low maintenance requirements, easy serviceability, and high efficiency.
