Balanced Workload for Parallel Systems

SubDrive Duplex Alternator

Franklin Electric’s SubDrive Alternator allows a water system to alternate between two parallel pumps controlled by separate SubDrives. The user-selected switching interval balances the run time of each pump system to evenly disperse the workload. The SubDrive Duplex Alternator is ideal for applications requiring redundant systems.

For high demand situations, the Alternator works on a lead-lag principle. When demand exceeds the capacity of one pumping system, the other comes online to supplement production.
