Variable-speed, multi-stage, centrifugal electric pump in a horizontal mono-block unit, controlled by the ESPA ESD frequency inverter.

Designed for pressurising homes, low-scale irrigation systems and clean-water pumping applications that require a sturdy, compact, automatically-regulated pump.

Self-priming up to 9 m, especially recommended for potable water applications.

The pressure reading is taken in real time to adapt the engine's revolutions and adjust the flow provided to the facility's demand. This achieves greater comfort for the user, by ensuring a constant water supply pressure. The reduction of the engine frequency also implies a significant energy saving and better efficiency of the facility.
