Micro Annular Gear Pumps are rotary pumps that are constructed with an externally toothed internal rotor as well as with an annular tooth external rotor, which are slightly eccentric to each other. During rotation of the rotors around their offset axis, the pumping chambers simultaneously increase on the induction side and decrease on the delivery side of the pump. A homogeneous flow rate is generated between the kidney-shaped inlet and outlet. |
