ABSTRACT:
The invention relates to a method and apparatus for driving the impeller (5) in a turbo-type liquid pump operating at relatively low power and relatively high delivery head by means of an a.c. motor (2). The invention is mainly characterized in that the motor (2) is driven from a static inverter (6) which operates at an operating frequency of 100-1000 Hz. This enables high specific speed impellers to be used, and therewith provides a considerable increase in the efficiency and capacity of the pump at unchanged motor sizes.
