ABSTRACT:
A delivery system is disclosed for pumping and pressurizing viscous fluid materials, such as molten glass. The pump comprises a rotating rotor which is located in a channel of the viscous fluid, such as in the forehearth of a glass melting furnace. In a glassmaking operation, the rotor uses the viscous drag of the molten glass against it to pump the molten glass from an open channel into a closed and pressurized channel where the pressurized molten glass may be, for example, extruded into glass filaments. The pumping system described also finds utility in pumping other viscous materials such as resins in fluid form.
