Abstract: A gear pump with reduced power requirement for conveying viscous liquids, especially thermoplastic fiber-forming polymer melts or a viscose spinning liquid, with intermeshed gear wheels rotatably mounted on parallel shafts while encased or circumscribed in a pump housing, i.e. enclosed on either side of the gear wheels and around the periphery thereof with an inlet opening for liquid feed means leading into the meshed point or area where the gear wheels disengage or become unmeshed and with an outlet opening for liquid discharge means leading away from the meshing point or area where the gear wheels engage or become meshed, the liquid thus being conveyed by the gear teeth from the inlet opening on one side of the meshing point around the outer portion of each gear to the outlet opening on the other side of the meshing point. A normal pressure-sealing or backflow-inhibiting radial gap is provided over at least a portion of each gear wheel periphery, i.e.
