The three-phase pump is equipped with an electric motor powered by three phases, ie by three sinusoidal voltages, and is used above all in the case of medium-high powers, such as in the industrial and automation sectors. For the lower ones, however, we use the single-phase pump, which is usually found in our homes. In order to work, the three-phase motor requires the use of a three-phase system of 120° out-of-phase currents, ie a generator consisting of three alternating current circuits

What is the main function of hydraulic pumps?

The hydraulic pumps, through the energy produced by the engine, have the task of moving the flow water allowing the water to move from one point to another. The purposes of the electric pumps or centrifugal pumps, named so because they work thanks to the power of the electric motor and the movement of the impellers, are many including: to make the liquid emerge from the bottom of the well on the surface, clean the water of a pool in order to be able to filter it, to disperse the water to several houses after having collected it in a cistern and to desalinate the water, exploiting the hydraulic pressure for the recovery of water.

The electromechanical panels with three-phase pumps

Our direct-start electromechanical panels represent the most functional, simple and traditional system since they allow the motor to be connected directly to the electrical network. They can also be equipped with a single-phase or three-phase pump for applications with clean water or waste water. This type of starting is especially suitable for electric pumps and electric motors that require a reduced number of starts per hour, like our Autoel-1. Easy Soft-1 is the electromechanical start-up soft-start and soft-stop of a three-phase pump, always suitable for applications with clean water or waste water. Its biggest advantages are: gradual start-up, engine protection, reduced water hammers and protection against dry running by floats.
