PURPOSE:To continuously mix and feed under pressure a uniform mixed material by providing gaps between a pair of rotors which are housed in a rotor chamber and which are meshed with each other and in between a casing which forms said rotor chamber and said rotors, respectively, and forming a pump. CONSTITUTION:A casing 5 having a rotor chamber 4 which is communicated to a suction port 2 and a delivery port 3 inside, is provided between the suction port 2 and the delivery port 3, and a pair of male and female screw rotors 6, 7 are meshed with each other in the rotor chamber 4, to form a pump body 1. And, gaps 8, 9 are provided in between the rotors 6, 7 and between the rotors 6, 7 and the casing 5, respectively. Thereby, materials to be mixed are sucked from the suction port 2 into the tooth groove parts 10 of the rotors 6, 7 in the rotor chamber 4, and enclosed while leaving the gaps 8, 9, and the enclosed materials are moved to the delivery port 3 side accompanying the rotation of the rotors 6, 7. And, the capacities of the tooth groove parts 10 are reduced with their movement, to mix the materials.
