Abstract (en)
[origin: EP1344942A2] An electrically motorized pump with a low energy loss owing to its use of a shaft and sleeve made from synthetic resin composition obtained by uniformly dispersing fine powder of RBC or CRBC in a resin. The typical process for the production of a synthetic resin composition for making the sleeve bearing for the pump for use in water includes kneading with a resin the fine powder of RBC or CRBC at a temperature in the neighbourhood of the melting point of the resin, and thereby uniformly dispersing the fine powder of RBC or CRBC in the resin. <IMAGE>
