Variable Speed Pump Controller Matches Hydraulic Needs

The S-Drive simplex variable speed pump controller features simple wiring, start-up and programming. The controller is pre-packaged in an outdoor NEMA 3R enclosure. It is designed for use with both submersible well and above ground centrifugal pumps as well as for building water boosters. It’s pre-set for submersible or surface motor characteristics and pre-wired to reduce set up time. It is a true variable frequency controller that adjusts motor speed to match the hydraulic needs of the system to maintain pressure up to 70% energy savings over fixed speed pumps is common. The same drive can be used for either single- or three-phase power and is rated for the higher start-up amps required by higher horsepower submersible pumps.
