Abstract

1376206 Centrifugal pumps GORMAN-RUPP CO 24 March 1972 [24 March 1971] 13957/72 Heading F1C [Also in Division F2] A self-priming centrifugal pump has a substantially axial inlet and an access opening with a removable cover which is laterally spaced from the axis in order to provide access to the pump chamber without disconnecting the connections to the inlet passage and discharge opening, and a volute which is detachably mounted in the chamber and which can be removed through the access opening, the volute having a priming inlet and a discharge inside the pump chamber. The self-priming pump shown comprises a housing 12 forming a priming reservoir and containing a volute 16, the volute comprising a part 92 which is attached to the housing by bolts 100 and a part 106 which, as shown, may be integral with a cover 74 which closes an access opening 38. The volute part 106 affords a cutwater 110 and a portion 108 of the volute wall and has a lining 112 of plastics or rubber which resists wear and abrasion and also forms a seal between the cover 74 and the housing 12. The cover 74 is retained by a clamp bar 80 and a clamp screw 90. The inlet side of the volute 16 is closed by a wear plate 17 which is attached by screws 126 to an inlet assembly 20 which in turn passes through an opening 32 and is secured to the housing 12 by screws 50. The wear plate 17, impeller 15, volute part 92 and shaft seal 30 are removable, in that order, through the access opening 38. A check valve assembly 44, which is sandwiched between flanges of the inlet assembly 20 and a suction pipe 19, is removable without disturbing the inlet assembly and suction pipe, after withdrawal of bolts 68.
