Abstract

1,151,742. Centrifugal pumps. HAYWARD TYLER & CO. Ltd. June 16, 1966 [June 24, 1965], No.26799/65. Heading F1C. [Also in Division H2] An electric motor driven pump has the pump and motor housings joined by a neck portion to form a common liquid enclosure wherein the portion of the drive shaft extending through the neck portion has applied thereto a thin sleeve of thermal insulating material. The material 21 is retained in the bore of a thin outer metal sleeve 22 which is shrunk on to the shaft or fixed by screws 23. Asbestos or other thermal insulating material may be used or alternatively sleeve 22 may have holes in it so that it will fill with the pumped liquid to form the thermal insulating sleeve. In a further embodiment the material is applied directly to the shaft and adheres to it and may be constituted by ceramic or synthetic plastics material.
