Aquavar® e-AB Series (e-AB2/e-AB3)

Constant Water Pressure for the Way You Live

The Aquavar e-AB Series constant pressure booster systems, comprised of the e-AB2 and e-AB3, are designed to deliver increased water pressure when water demand is high. These systems are ideal for both customers of municipal water districts with low water pressure, and those boosting from a storage tank.

How does it work?

For many customers of municipal water districts, low or inconsistent water pressure can be a problem when they have any combination of multiple bathrooms, irrigation systems, dishwashers, washing machines, pools and spas. In addition, peak water demand on the line caused by more homes and businesses on the water main can reduce main line pressure available. As water flows to a house, it loses some of its pressure to friction inside the pipe. The higher the flow, the more the friction reduces your water pressure. As water use increases, the Aquavar e-AB Series booster systems change pump speed to keep line pressure constant. Simply set the desired pressure and the smooth control will take over. Large supply tanks are eliminated and up to 50% of the energy required by a fixed speed pump is saved. The Aquavar e-AB Series booster systems are available with a range of flow rates to handle residential homes, irrigation systems and office buildings.
