Abstract (en)

[origin: WO2020020864A1] A volumetric pump comprising a chamber (1) having a breadth, B, an inlet volume with an inlet and an outlet volume with an outlet, separated from each other m pumping systems enclosed in the chamber, with m ϵ N, and m>1, each pumping system comprising, at least a portion of one of m/k radial cams (3i) with k ϵ N and k>0, comprising at least two noses, wherein the m/k cams are rotatably mounted on an axis of rotation, Z1, parallel to the breadth; a vane movingly mounted in the chamber to keep permanent contact with a circumference (3t) of the radial cam, wherein each pumping system delivers by rotation of the corresponding cam a volume, Vi, of fluid from inlet to outlet at a flow rate, Qi=dVi/dt, wherein, the sum of the nominal flow rates and of volumetric displacements are, within a tolerance, constant.
