rotarus® Pump Heads
Peristaltic pumps are so-called roller pumps in which the rollers are rotated over a tube fitted in the pump head, leading to the mechanical deformation (squeezing) of the tube. The restitution of the tube following the roller triggers pumping of the medium in the interior of the tube. As a consequence, only the pump tube comes into contact with the medium. The flow rate is determined by the geometry of the roller head, the speed of the roller head, the number of rollers and the inner diameter of the tube
Speedier change, more versatile functions
The rotarus® range encompasses a comprehensive selection of single and multichannel pump heads. The pump head connection technology was developed for rapid handling. Changing of heads is realised quickly and simply in a single action without using tools.
Pump heads from other manufacturers can also be fitted without difficulty using an adapter. rotarus® single channel pump heads are easily cascaded (i.e. they can be stacked in an assembly and operated on a single rotarus® pump).
Robust, reliable single channel pump head for versatile applications in the lab and industry
