SJE Rhombus WellZone Pressure Controller

Company Says It Eliminates the "Traditional" Pressure Switch

March 6, 2023

SJE Rhombus offers the WellZone Pressure Controller, which it calls a longer-lasting option in pressure switches for single-phase 115/230 volt well pumps. WellZone eliminates the “traditional” pressure switch, a common failure point. Protects against rapid cycling, low pressure, run dry, overpressure, overcurrent and undercurrent. Provides pressure control for single-phase 2-wire submersible well pump applications. Uses 0-150 PSI pressure transducer to monitor discharge pressure and turns pump on and off according to set start and stop points. NEMA 4X enclosure. www.sjeinc.com
