Booster Pumps are auxiliary pumps which are used to increase or maintain pressure in a potable water system. They are most commonly used in systems where there is an inconsistent demand for water. When the demand is low, the booster pump in in standby. When the demand is high, the booster pumps is activated and maintains the necessary water pressure to meet the increased demand.
Booster Pressure Systems typically incorporate one or more pumps, tanks and control devices. They are designed to maintain adequate water pressure in low pressure areas, "mid-rise" structures, "high-rise" structures, and facilities that have a high variance in water demand. Booster pressure systems operate when the rate of water usage increases and/or the water supply pressure drops below acceptable levels.
Circulation Pumps are used within plumbing systems to circulate special liquids, liquified gases and potable water. Circulation pumps are normally centrifugal but also include turbine pumps.
