ABSTRACT:
A drum pump for a turbine which comprises a turbine housing having an internal wall defining an interior cylindrical chamber. A cylindrical drum having an outer cylindrical surface and an annular channel formed on its inner surface is coaxially rotatably mounted to the housing within the housing chamber so that the outer periphery of the drum is spaced radially inwardly from the housing wall. A pair of axially spaced annular fluid seals extend between the housing and the outer periphery of the drum and form an annular outlet chamber therebetween. At least one outlet passageway is formed in the housing and open to the outlet chamber while, similarly, a connecting passageway is formed from the drum and extends between the channel and the outlet chamber. A fluid jet supplies fluid to the drum channel so that, upon rotation of the drum, the fluid is centrifugally pumped out through the connecting passageway, to the outlet chamber and out through the outlet passageway in the housing.
