Booster system with submersible pumps and VFD
The pump driver must be installed on the delivery pipe. This device is characterized by pressure signaling through an integrated pressure transducer.
The water passage VFD characterized by ease of installation with elements. It is equipped with a pressure sensor that acts a transducer inside the device.
The right size VSD will save you money and also make sure that the system is energy efficient. With an inverter drives, the pump is operated when the tap is opened and calibrated based on the actual water requirement (by modulating the power according to actual needs. Using a adjustable frequency drives will save you from 30% to 50% of electricity per year).
There are three types of variable speed drives for electric pumps:
1)Single-phase/single-phase VFD (M/M inverter drives)
2)Single-phase/three-phase VFD (M/T inverter drives)
3)Three-phase/three-phase VFD (T/T inverter drives)
The schemes with the various types of inverter drives are shown below:
Single-phase 230M - single-phase 230M (MM inverter drives)
Pratical example: ACTIVE.DRIVER.MM.1,1
The VFD is powered by a single-phase 230Vac power supply - The electric pump is also powered by a single-phase 230Vac power supply.

Single-phase 230M - three-phase 230T (MT inverter drives)
Pratical example: ACTIVE.DRIVER.MT.1,0
The VFD is powered by a single-phase 230Vac power supply - The electric pump is powered by a three-phase 230Vac power supply.
Warning! we said 230Vac three-phase so that all electric motors that are normally powered by three-phase 400Vac can be adapted for this power supply, while the submersible pumps must specifically request to be powered by 230Vac three-phase.

Three-phase 400T - three-phase 400T (TT inverter drives)
Pratical example: ACTIVE.DRIVER.TT.3,0
The VFD is powered by a three-phase 400Vac power supply - The electric pump is powered by a three-phase 400Vac power supply.
