eFlow: Electronic flow switch for electric pumps

eFlow is an electronic flow switch for single-phase pumps up to 1.5 HP, designed to automatically start and stop the electric pump according to the opening or closing of water outlets.

The device stops the pump in case of water shortage, protecting the system from dry running and contributing to safer system management.

It can be powered at either 115 Vac or 230 Vac and is suitable for single-phase pumps used in residential and professional pressurization systems.

eFlow is Made in Italy and requires no maintenance.

eFlow electronic controller applications

eFlow is suitable for pressurization systems with single-phase electric pumps used in:

  • domestic water systems
  • residential pressurization systems
  • applications with surface pumps
  • installations where dry-run protection is required
  • systems requiring automatic control based on water flow

The device must be installed so that it is crossed by a minimum flow when a water outlet is opened.



Features

eFlow manages the start and stop of the pump based on the flow generated by the opening or closing of water outlets.

In the absence of water, the device stops the pump, reducing the risk of system damage.

Compatible with 115 Vac and 230 Vac power supply, allowing greater adaptability to existing configurations.

Status LEDs indicate: device powered pump running. A button allows manual reset after a fault.

The flow switch does not require routine maintenance.
