The NEMO® BH hygienic pump in compact block design is used for hygienic applications in the food, pharmaceutical, cosmetic and chemical/biochemical industries because of its optimal process characteristics .
The progressing cavity pump impresses with its continuous, pressure-stable, gentle and low-pulsation conveyance that is independent of pressure and viscosity fluctuations, as well as with dosing in proportion to speed. The hygienic design of the components and machines, as well as the cleanability of the system parts (CIP and SIP capable) are defined in a multitude of regulations. NEMO® pumps are designed, manufactured and tested in accordance with FDA (Food and Drug Administration) as well as EU VO 1935/2004. In addition, NEMO® hygienic and aseptic progressing cavity pumps meet the requirements of the 3-A Sanitary Standard of the USA and are GOST-R certified (certificate of conformity for Russia). The NEMO® BH is particularly compact and economical in block construction with flanged drive.
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. Stator inlet with hopper-shaped opening for improved feed into the conveying chamber.
3 Hygienic joints
Patented open, crevice-free hygienic joints for optimal cleaning.
4 Drive chain
Drive and connecting shaft with coupling rod and two hygienic joints for the transmission of power from the drive to the rotor.
5 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.
6 Protective tubing for stator
Made of stainless steel (optional).
7 Block construction
The drive is flanged directly to the lantern, 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.
