ABSTRACT:
In order to reduce the requirements for cleaning and provide a structure which is also easy to disassemble for cleaning without the use of tools, a pump, which has a rotary element such as an impeller shaft, is provided with a seal which is arranged so that an annular seal element, such as an O-ring, is disposed in an annular chamber which is sufficiently elongate to allow for a small amount of reciprocal movement of the seal element therein. The movement of the seal member promotes a self-cleaning action which obviates the build-up of particulate material in the annular chamber.
