Abstract: A pump for conveying molten masses of polymers and/or elastomers comprising a pump body in which are formed an inlet duct for entry of the material, an outlet duct for discharge of the material and a central body communicating with the inlet and outlet ducts and destined to house at least one gear mounted on a motorized shaft for conveying the material from the inlet duct toward the outlet duct. The pump body consists of two parts that can be assembled together, each part of the pump body comprising at least one through hole communicating with the central chamber, so that said at least one shaft of the gear is rotatably supported directly in the pair of opposite facing holes of the two parts of the pump body.

Abstract: A pump (1) for conveying molten masses of polymers and/or elastomers comprising a pump body in which are formed an inlet duct (7) for entry of the material, an outlet duct (8) for discharge of the material and a central body (11) communicating with the inlet and outlet ducts (7, 8) and destined to house at least one gear (15, 16) mounted on a motorised shaft (18) for conveying the material from the inlet duct (7) toward the outlet duct (8). The pump body consists of two parts (2, 2′) that can be assembled together, each part of the pump body comprising at least one through hole (14) communicating with the central chamber (11), so that said at least one shaft (18) of the gear (15, 16) is rotatably supported directly in the pair of opposite facing holes (14) of the two parts (2, 2′) of the pump body.
