Water Booster Systems Wastewater Lift Station Sears Tower
The utilization of variable frequency drives provides a wide range of benefits for a variety of
pumping systems. From sanitary and storm water to domestic and municipal water systems,
VFD’s offer several advantages over constant speed systems including: reduced energy
consumption, constant pressure supply, improved system control and operation, steady-state
flow, surge and water-hammer reduction, reduced wear and damage to system components,
and increased pump life.

191 N. Wacker, Chicago, IL
Variable speed water pressure systems use a
transducer to sense pressure and automatically vary
the speed of the pump(s) to maintain a constant
discharge pressure regardless of the system
demand. Energy is saved due to the elimination of
PRV valve losses and also developing a constand
pressure at all flow conditions.
