factory tested systems including a close-coupled pump, Direction of rotation : Clockwise as seen from the motor rear end
bladder type pressure tank, pressure switch, pressure gauge
(or electronic switch), special connector and flexible pipe for APPLICATIONS
systems with pump over the tank. These pumps are suitable for liquids which are potable & rain
water other than thin, clean, non-aggressive, non-explosive,
These systems can provide sufficient water pressure for not containing solid particles or fibres.
modern domestic appliances to ensure sufficient water Pumps are designed for liquid transfer & pressure boosting
supply. Thus these systems are widely used in domestic systems in:
water applications to stabilize the pressure in the system and  Households, commercial complexes
avoid the pump cycling on and off every time a tap is opened  Gardens,
somewhere in the house.  Agriculture
 Horticulture
 Small industries
These systems can work according to the any decrease or  Car washing
increase of pressure, the pressure switch determines when  Cooling systems
the pump will start or stop.  Drawing water out a well.
FUNCTION
The booster set cuts in and out by means of the pressure switch. When water is tapped from the system, it will at first be tapped from
the pressure tank, see below fig. Then the pressure falls to the preset cut-in pressure and the pump will cut in. When the water
consumption drops, the discharge pressure increases and the pump cuts out when the pressure reaches the preset cut-out pressure
of the pressure switch.
