Abstract

The pump inlet ring is particularly for use with cryogenic fluid. It comprises a hollow cylindrical moulding (1) fixed at the pump end (7) to a shaft. At the other end it is shaped into spiral blades (2) ending in sharp edges (6), to form a vibratory cage. As it rotates, these edges engage with the fluid at the inlet end, delivering it axially between the blades and radially outwards.
