Abstract

426,523. Centrifugal pumps; stuffing-boxes. WALLWIN, J. M., Saltisford Iron Works, Warwick. May 2, 1934, No. 13237. [Classes 110 (i) and 122 (v)] An impeller is secured to its hollow shaft j by a stem k which passes through the shaft and is screw-threaded to receive at one end an impeller nut h and at the other a tightening nut l. The impeller is adjusted by an axially movable thrust bearing n which lies between adjustable collars o. Stuffing-boxes.-The ordinary gland screwed to the casing may be replaced by a flexible tapered sleeve z with a retaining bead w. Narrow vanes y expand the sleeve when the pump is in operation. The impeller and casing are rubber lined.
