The Rotho peristaltic pump is a volumetric pump and able to resolve a number of production problems in a variety of industrial sectors.
Thanks to the concrete results achieved in the most diverse production processes, the Rotho has attracted interest from all sector experts.
Many peristaltic systems use sliding blocks to compress the tube. This means the tube must be immersed in refrigerant liquids to mitigate the friction caused by the blocks compressing the tube.
Rotho technology using rollers on bearings does not require refrigerant liquid in the stator. Maintenance is therefore faster and less wasteful and there is no refrigerant liquid to dispose of.
The Rotho pump also safeguards the quality and hygiene of the product, as there is no refrigerant liquid which could contaminate the product if the tube ruptures.
The Rotho peristaltic pump can be used in numerous applications thanks to its ease of use:
The pump operates on the principle of peristalsis, as used by the human digestive system, which contracts then relaxes a muscle around a tube causing the contents to move through it.
In the pump, an elastomer tube is repeatedly compressed down its full length by rollers. Between one pass of the propelling roller and the next, the tube returns to its original diameter, creating a vacuum which draws in the product to be transferred.
This movement generates a delicate pumping action, avoiding even minimal damage to the product and preventing any form of contamination by eliminating contact with mechanical parts.
In the Rotho pump, the mechanism employed to compress the tube by means of rollers on bearings has a number of advantages
