Mains voltage

The supply voltage for which the pump with an electric motor is designed is electric or battery (see "Power source").

— 230 V. Voltage of ordinary household mains. Most pumps with this power supply can work directly from the socket, only the most powerful models (3 kW and above) require a special connection format (directly to the switchboard). However, 230 V mains are relatively poorly suited for high-power units. Therefore, this type of power supply is found mainly among electric pumps of low and medium power, designed mainly for domestic use.

— 400 V. Power supply from three-phase 400 V mains is suitable for electric pumps of any power — including heavy industrial equipment. However, this type of power supply is also found among relatively "weak" models — including 400 W and below. This is because a three-phase connection has several general advantages over a single-phase one: in particular, such mains are better able to withstand high loads (including power surges during motor starts), they are better suited for long-term continuous operation, and also allow more accurate accounting of consumed energy. If there is access to a 400 V mains at the pump installation site, it is most likely that such a power supply will be optimal.

— 12 V. A value that is practically not found among mains pumps, but quite popular in battery models (see "Power source"). In this case, voltage does not affect performance, but it may be useful when looking for a...replacement/replacement battery or third-party charger. At the same time, we emphasize that the use of 12-volt car batteries with pumps is highly discouraged: such energy sources are designed for a specific format of operation, and their abnormal use is fraught with accidents.

— 18 V. Another version of the operating voltage found in battery pumps; has no fundamental differences from the 12 V described above.
