EEZI Multistage Booster 1.1kw VSD

The EEZI-1.1-3P-VSD multistage centrifugal variable speed drive (also known as variable frequency drive VFD, VSD or Inverter Control) pressure booster pump system is suitable for distributing water under constant pressure & flow in residential housing, supermarkets, commercial buildings, resorts, complexes & industrial applications where the incoming municipal water supply pressure is inadequate.

The special operating system makes our variable speed drive centrifugal pumps an appropriate solution in all cases where water flow rates do not ensure suitable operating pressures. A Variable Speed Drive (VSD) regulates the speed and rotational force, or torque output, of the motor.

One of the main reasons why drives save energy is because they can change the speed of an electrical motor by controlling the power that is fed into the pump. The VSD can slow the motor down as slow as 35% of it rotational speed thus in turn saving of 65 % energy consumption. The VSD also allows for a soft start and stop which reduces the violent torque and water hammering, therefore extending the life of motors.

Throughout operation the VSD will offer a smooth flow and constant pressure at the desired pressure.

Please note when purchasing the EEZI-1.1-3P-VSD the system has been assembled at our factory and bench tested. The pump and VSD will remained assembled, but the pressure vessel, pressure gauge and four way stainless steel connection fitting will be supplied unattached. Reason for this is for safe transportation and to allow the customer different options of assembly.
