Abstract

Plastic impeller for rotary pumps is made of a fibre-reinforced plastic in which the fibres are oriented exclusively parallel to the rotational axis of the pump. The impeller is of low cost, thermal expansion and weight. It has good sliding characteristics, high strength and durability. The fibrous matl. is pref. harder than the resin matl. The impeller pref. consists of a glass fibre-reinforced epoxide resin with a fibre content of 70-75%.
