ABSTRACT:
A turbine driven pump wherein a multi-stage centrifugal pump unit is coaxial with and mounted on a common shaft with a turbine unit. The two units are connected to each other by a low-pressure section which defines a hydrostatic seal between the interior of the pump unit and the interior of the turbine unit. The inlet and outlet of the turbine unit are connected with each other by a conduit containing a regulating valve, and the inlet of the pump unit is connected with chambers at the outer sides of relief pistons disposed at the high-pressure sides of the two units. The diameters of the relief pistons are proportional to pressures in the high-pressure portions of the respective units. The inlet of the pump unit is coaxial with the outlet of the turbine unit.
