Progressive cavity pump Visco.pump®

The VISCO.pump® is based on the volumetric principle of an endless (infinite) piston whereas the core components rotor and stator form a perfectly sealed metering chamber. The eccentric movement of the rotor allows for a low-shear motion of the medium from one chamber to the next chamber without squeezing the media. Dispensing proportional to speed, accuracy and repeatability is ± 1%. Its light weight space saving design is highly applicable for small 3 and 4 axis dosing robots. Well suited for filled media the VISCO.pump® lends itself to countless applications where reliability and repeatability is a must.
