Abstract

A pump unit, which is intended for pumping corrosive fluids, comprises, in part, a submersible pump (1) having a pump housing (5), an impeller (9) situated therein, and a pump-housing cover (8) belonging to the pump housing, the impeller, the pump housing and the pump-housing cover consisting of corrosion-resistant material, and, in part, a motor (2) provided for driving the pump and having a motor casing (14a, 14b), a shaft (11) coupled to the impeller, and cable bushings (20, 21). In order to permit the use of materials which are less expensive and easier to work for as many parts of the pump unit as possible, the unit comprises a casing (24, 24a) which consists of corrosion-resistant material, encloses the said parts belonging to the motor, which are produced from material which is not corrosion-resistant, and whose lower end is connected to the pump-housing cover (8) and whose other, upper end is situated above the highest height of the surface of the corrosive fluid to be pumped (Fig. 1). <IMAGE>
