Abstract

1,062,946. Mechanical seals; washers. SPEEDWELL RESEARCH Ltd. Nov. 3, 1964 [Nov. 14, 1963; Feb. 19, 1964], Nos. 44947/63 and 6878/64. Headings F2B and F2H. [Also in Division F1] In a centrifugal pump having an impeller mounted on a shaft in a chamber formed by two releasably-connected casing components, seal faces on a gland part in one casing component and a gland part on the shaft engage with relative rotation and are flushed at their outer peripheral edges by the liquid being pumped to prevent the formation of crystals at the faces. A collar 38 of ceramic, stainless steel or titanium, is supported in a rubber sealing ring 37 mounted in a rebate 36 in a casing component 10. A face 41 on the collar sealingly engages a face 42 on a graphite ring 43 engaging a rubber sealing ring 44 and embracing a sleeve 29 pinned at 32 to the shaft 31 of an electric motor 26a. Any liquid leaking past the faces 41, 42 is flung by a disc 33 out of peripheral spaces between the casing component 10 and the electric motor. A casing component 11 is detachably secured to the component 10 with a seal 21 therebetween, by three equi-angularly spaced thumb screws 22. Removal of the component 11 and a screw 50 permits removal of the impeller and rings 43, 44 for cleaning. The screw 50 abuts a rubber sealing washer 51 provided with a metal locking insert. The screw 50 and sleeve 29 may be of stainless steel or titanium.
