Abstract

A dosing pump is provided comprising a working membrane defining a working area, and a pump drive for creating an oscillating movement of the working membrane. The direction of the pump drive can be inverted and the displacement element can be moved back and forth. The inventive dosing pump also comprises a position sensor for detecting the position of the pump drive, an electronic control system for the same, and a pump head in which an inlet valve and an outlet valve are arranged. The pump drive comprises a positioning motor and can be displaced back and forth in an oscillating manner, with the part thereof connected to the displacement element, in any range of its entire working displacement, according to a pre-determinable course, for a reduced pump capacity in relation to the maximum pump capacity. At least the inlet valve is externally controlled and comprises a motor-driven valve drive. The electronic control system is connected to at least the motor-driven valve drive(s) of the inlet and/or outlet valves, to the positioning motor of the pump drive, and to the position sensor for detecting the position of the displacement element and/or the pump drive. The combination of the electronically controllable positioning motor, the oscillating movement of the pump drive within any range of its entire working range, and the use of an externally controlled inlet and/or outlet valve significantly enlarges the operative range of the inventive dosing pump.
