Abstract
The present invention is directed to a multiport metering pump that can completely deliver a very small volume of liquid. The multiport metering pump includes a number of ports (or valve units), each of which can be used as either an outlet valve or an inlet valve. The multiport metering pump includes: a central gallery; a displacement unit; multiple valve units; and multiple conduits that respectively connect the displacement unit and the valve units to the central gallery. The displacement unit and the valve units communicate with the central gallery, and any of the valve units can be used as an inlet valve or outlet valve for the liquid delivery.
