Max. power consumption

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.

Inlet

The size of the inlet provided in the design of the pump. For plumbing threads (see Connection), the size is traditionally indicated in inches and fractions of an inch (for example, 1" or 3/4"), for flanges, the nominal diameter (DN) of the bore in millimetres is used — for example, DN65.

This parameter must match the dimensions of the mount on the pipe to which the pump is planned to be connected — otherwise, you will have to use adapters, which is not very convenient, and sometimes not recommended at all.

Outlet

The size of the outlet provided in the design of the pump. The value of this parameter is completely similar to the size of the inlet (see above).
