Technology mzr^®-pumps

Micro annular gear pumps are positive displacement pumps and are provided with an external toothed internal rotor as well as with an annular toothed external rotor which bear slightly eccentric to each other. Both rotors with their cycloidal indenting are at any time interlocked and form a system of several sealed pumping chambers during rotation. As the rotors rotate around their offset axis, the pumping chambers increase on the induction side and decrease on the delivery side of the pump at the same time. A homogeneous flow rate is generated between the kidney-like in- and outlet.
