The 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, the 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).
Rotor – Two geometries and with polished surfaces.
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.
Sanitary Joints – Patented open crevice-free sanitary joints for optimal cleaning.
Drive Train – Drive and connecting shaft with coupling rod and two sanitary joints for the power transmission from the drive to the rotor.
Seal Casing – Shaft seals suitable for contact with food producs, with compression-proof, bolted shaft seal housing, enable a reversal of the direction of rotation up to the maximum pumping pressure.
Protective Tubing for Stator – Made of stainless steel (optional).
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.
