Definitions

the invention relates to a pump housing with a pressure and / or suction nozzle, with which the housing is connectable to a line, wherein the nozzle is surrounded by a rotatable annular mounting flange to which the line is fastened in particular screwed.
Rotatable annular mounting flanges on the neck of a pump housing have the advantage that pipes with a variety of types of fastening can be attached without having to change the pump housing itself or its neck. In this case, it has been shown that a secure mounting of the rotatable annular mounting flange is structurally complex.
the object of the invention is to make the storage of a rotatable annular mounting flange on the neck of a pump housing structurally simple and secure with ease of manufacture and assembly.
the nozzle has an internal thread into which a socket with its external thread can be screwed, and that the socket forms a flange against which abuts the annular mounting flange.
the annular mounting flange has holes for screw fasteners in particular regular intervals. It is particularly advantageous if the annular attachment flange has protruding parts, in particular ribs, between the bores, for the abutment of nuts or screw heads. As a result, a rotationally secure hold of the nuts or screw heads is achieved during assembly.
the pump housing forms the lower portion of a multi-stage pump, wherein on the opposite side of the suction port on the housing, a housing tube is fixed, in which two or more pump impellers are arranged on the pump shaft.
the housing 1 of a pump forms in the embodiment, the lower portion of a multi-stage pump, wherein on the top of the housing a Housing tube is fastened, in which two or more wheels are mounted on the pump shaft.
an electric motor is attached on the upper side via a lantern.
the sockets 2, 3 each have an internal thread 4, in each of which a socket 5, 6 with its external thread 7, 8 can be screwed.
the bushes 5, 6 have on the end facing away from the housing 1 each have a molded flange 9, 10, which projects beyond the outer diameter of the nozzle when screwed into the socket socket.
an annular mounting flange 11 and 12 is pushed onto the nozzle, which rotatably mounted on the nozzle and held by screwing the sockets 5, 6 by the flanges 9, 10 are.
the inner diameter of the inner opening of the annular mounting flange is only slightly larger than the outer diameter of the nozzle and smaller than the outer diameter of the flange 9, 10th
the annular mounting flanges 11, 12 have bores 13 in particular at regular intervals, wherein in the bores 13 screws not shown can be used, through which the ends of lines / pipes can be fastened.
the lines / tubes, not shown preferably have flanges with bores at their ends.
On the back of the rotatable mounting flange 11 are ribs 14 in pairs next to each hole 13 before, wherein the distance of the ribs 14 of a pair of ribs corresponds to the distance of the flattenings of a nut or a screw head, so that the nuts or screws used secured during tightening against rotation are.
a base plate 15 is screwed, which is preferably made of sheet metal.
