Domestic Booster Pumpsets

What is a Domestic Booster System & How does it work?

Booster Pump systems are designed to improve the water pressure in your piping system. They are suitable to homes and offices where the water pressure is low or where the pressure of the water is dependent on gravity. Booster pump systems come with a pressure tank. The pressure tank consists of a diaphragm enclosed within air pressurized tank. When pumpset is turned on, the diaphragm expands within the same tank, since air is compressible, the volume occupied by air decreases while the pressure increases. The amount of pressure to be imparted is controlled using a pressure switch. The pressure switch has two scales on it – Range and Difference. Range refers to maximu pressure and is used to set the cut out pressure (pressure at which pumpset is turned off). Difference refers to level of p[ressure drop and is used to set the cut in pressure (pressure at which pumpset is turned on).

Eg. If range is 3 bar and difference is 1 bar. The cut off pressure is 3 bar and the cut in pressure is 2 bar. (i.e Range = cut out pressure and Range-Difference =cut in pressure)

When the water pressure in the pipe line comes down blow the cut-in pressure, the pumpset will switch on and when pressure increases to cut-out pressure, the pumpset will switch off.
