Positive-displacement pump e.g. gear pump, for use as mixing device in e.g. beverage dispenser, has conveyor elements rotatably supported at pump housing, and drive device driving conveyor element by electrical/magnetic field forces

摘要

The pump (1) has pump housing (2) and two conveyor elements staying effectively with each other. The elements are rotatably supported in the pump housing. A drive device drives one of the conveyor elements by electrical/magnetic field forces. The pump is designed as a gear pump, rotary pump and as a rotary piston pump. The two conveyor elements are guided in a conveyor chamber (6) in the pump housing or in an intermediate element (4) arranged in the chamber. The conveyor elements and the intermediate element are easily mountable and/or dismantable.
