Inverters for pumps

Inverters for Electric Pumps: Hydraulic System Efficiency and Energy Consumption Under Control.

The inverters applied to surface pumps, submersible pumps, or drainage submersible pumps are designed to optimize the hydraulic system's performance in terms of pressure and energy consumption reduction, thanks to their ability to regulate water flow.

The inverters for electric pumps are electronic devices that regulate the motor speed, adjusting it to the actual water demand. This dynamic power control helps improve efficiency, reduce energy consumption, maintain constant liquid pressure, and increase the lifespan of the hydraulic system.

The operation of an inverter is based on varying the supply frequency of the hydraulic pump motor, allowing modulation of speed and torque according to operational needs. Instead of always running the pump at maximum capacity, the inverter regulates the flow, reducing energy waste and preventing dry running. Additionally, with the soft-start and soft-stop control, current spikes and mechanical stresses on the system are reduced.

The most common applications of inverters for electric pumps include agricultural irrigation systems, pressurization systems in residential and industrial buildings, as well as wastewater treatment and distribution. In these situations, using an inverter ensures constant water delivery, improves comfort, pressure stability, and significantly reduces operating costs.
