The electrical power consumed by the pump during normal operation and maximum performance.

This indicator directly depends on performance — after all, for pumping large volumes of water, an appropriate amount of energy is needed. And the power depends on two main parameters — electricity consumption and the load on the power grid, which determines the connection rules. For example, pumps with a power of more than 5 kW cannot be connected to ordinary household sockets; more detailed rules can be found in special sources.

Operating voltage for which the pump is designed.

— 230 V. Standard voltage of household networks. Most of these pumps can be powered from a regular outlet, which makes them very convenient to connect. At the same time, this option is not well suited for creating high-performance units — already with a power consumption of more than 5 kW, certain tricks in connection will be required, and in general, 230 V provide less power than 400 V. Therefore, the such power supply is typical mainly for models elementary and intermediate levels.

— 400 V. This option implies power supply from three-phase networks with a voltage of 400 V. Such networks are rarely found in everyday life, but they are widely used in the professional field, including at industrial facilities — they are convenient for powering high-power equipment. Therefore, three-phase power is usually provided in professional high-performance pumps.
