Abstract
The shaft of a glandless pump which is made of sintered oxide ceramics in order to resist chemical attack is formed with a projection upon which there is mounted a metal sleeve having a bottom in order to enable a tool, such as a screwdriver, to be applied against the shaft for rotating the shaft when unblocking the pump without causing damage to the ceramic material of the shaft.
