GENERAL FEATURES
The main purpose of a water booster is to keep the pressurized water in the
installation ready for use at any time.
There are three main parts in a water booster.
- Motor and Pump (Motopump)
- Automatic Control Equipment:
- Pressure Compensating Tank (must be purchased separately)
Motopump: It pressurizes water. ALD water booster motors are three-
phase and vertical.
Automatic Control Equipment: It is the equipment that provides the automatic
operation of the water booster according to the pressure changes in the installation
and whether the feed water is available.
Pressure Compensating Tank: Its main purpose is to compensate pressure changes
in the installation and to keep the number of commissioning and decommissioning of
the pump (number of switches) in the most appropriate number.
