Variable Volume Chilled Water Pumping System Controls

Multiple Variable Speed Secondary Pumps. 2-way valves at all chilled water coils and secondary bypass loop with 2-way valve. • Each primary pump pumps water through a chiller. These can be piped so either pump can work with either chiller if isolation valves are used at each chiller or with dedicated primary pumps for each chiller.

Collection Systems Technology Fact Sheet: Sewers, Lift Station

Because variable-speed pumping allows lift station discharge to match inflow, only nominal wet-well storage volume is required and the well water level is maintained at a near constant elevation. Variable-speed pumping may allow a given flow range to be achieved with fewer pumps than a constant-speed alternative. Variable-speed stations
