A screw-spindle pump comprising: first and second screw spindles forming running and drive spindles, respectively, and a pump housing configured to receive the first and second screw spindles. The first and second screw spindles form, with at least the pump housing, delivery chambers, moving from a suction side to a pressure side of the pump as a consequence due to rotation of the screw spindles. The pump housing has an elongate insert, as an abutment for the first and second screw spindles and against which the first and second screw spindles are supported, the elongate insert having a first portion forming a first abutment for the second screw spindle and a second portion forming a second abutment for the first screw spindle. The elongate insert is clamped into a receptacle of the pump housing using a cross-sectional dimension of the elongate insert. 115-. (canceled)16. A screw-spindle pump comprising:{'b': 14', '16', '16', '14', '16, 'a first screw spindle () and a second screw spindle (), wherein the second screw spindle () is a drive spindle and the first screw spindle () is a running spindle that runs oppositely with respect to the second screw spindle (), and'}{'b': 10', '14', '16, 'a pump housing () configured to receive the first and second screw spindles (, ),'}{'b': 14', '16', '10', '18', '20', '22', '14', '16, 'wherein the first and second screw spindles (, ) form, together with at least the pump housing (), delivery chambers (), which move from a suction side () of the pump to a pressure side () of the pump as a consequence of a rotation of the first and second screw spindles (, ),'}{'b': 10', '8', '14', '16', '14', '16', '8', '16', '14, 'wherein the pump housing () has an elongate insert (), as an abutment for the first and second screw spindles (, ) and against which the first and second screw spindles (, ) are supported, the elongate insert () having a first portion forming a first abutment for the second screw spindle () and a second portion forming ...
