Introducing the latest in the family of SEI Submersibles! Advanced computer controlled constant pressure system for 3inch or larger wells. The state of the art Variable Frequency Drive system is designed to digitally control the pump motor speed as the pressure demand changes. This provides you with the convenience of constant pressure along with advanced pump system protection and diagnostics.

At the heart of the pump is efficient and reliable SEI motor designed to run up to 6,000 RPM with soft start and extremely smooth motor speed control. Coupled with the SEI 3” pump the unit provide years of maintenance free comfort. All of this is available in both normal and deep set models to cover the entire normal range of well depths.

The system comes prewired with a Danfoss pressure transducer mounted in a convection cooled NEMA 3R standard indoor rated enclosure. (outdoor rated enclosure also available).
