The researches of influence of a voltage deviation and current frequency for angular speed and technical characteristics of centrifugal pumps are carried out.

The dependences of productivity, pressure and capacity of pumps and the unit cost of electricity from the voltage are established.

Pump, electric drive, voltage deviation, current frequency, productivity, pressure, capacity of the pump, the unit cost of electricity.
