  • Publication number: 20030049143
    Abstract: The present invention is an integrated pump having structure that a plurality of cell pumps having an inlet and an outlet to send out fluid absorbed from the inlet to the outlet is connected in serial or parallel. A plurality of the above structured integrated pump may be connected in parallel. Thus, the integrated pump of the present invention can be obtained desired output according to the number of the connected cell pumps. Further, even if it becomes high output integrated pump by connecting many cell pumps for high capacity and high head, by unitizing individual cell pumps during the transportation or the installation, the transportation and the installation work for the integrated pump can be easily done.
