Abstract
949,463. Centrifugal pumps. G. NEIDL. Dec. 14, 1959 [Aug. 5, 1959], No. 27091/63. Divided out of 949,461. Heading F1C. In a pump having a disc-like impeller obliquely mounted on a driving shaft and surrounded by a casing with a clearance which is uniform along the periphery of the impeller, the impeller is circular or is an entire ellipse or the periphery of the impeller has two straight parallel portions connecting the two part-circular portions. Fig. 8 shows a pump having an inclined-disc impeller of circular or elliptical form but cut away at opposite ends to form chords 106, 107 adjacent the stuffing box 108 and inlet duct 109. The interior of the pump casing conforms to the solid of revolution generated by rotation of the impeller. As shown, the casing is divided along an inclined plane into two flanged portions. The inclined-disc impeller 83 shown in Fig. 3 is of elliptical form when viewed in the normal direction 80 and of circular form when viewed in a direction 81 perpendicular to the shaft 102. Alternatively, the impeller may be of circular form when viewed in the direction 80 so that it is of elliptical form when viewed in the direction 81.. As shown in Fig. 9, the impeller may have teeth fitting into annular grooves 113 machined in the pump casing. To permit insertion of the impeller, the casing is divided along two planes 114, 115 into four flanged parts 116, 117, 118, 119. The grooves 113 are machined as described in Specification 949,461. When the material handled by the pump has a high content of solids, as in the manufacture of paper, the inlet and outlet ducts are of large diameter, the diameter of the outlet duct preferably being equal to that of the casing, and the inlet duct is preceded by a funnel. Specification 879,546 also is referred to.
