Smart Digital Well Pump Control Panel – Replaces Traditional Pressure Switch Systems
The SJE WellZone® 3-Wire Control Panel is a digital pressure-based controller designed to replace outdated mechanical pressure switches in single-phase, 3-wire submersible well pump systems.
Using an included 0–150 PSI pressure transducer, the WellZone® continuously monitors system pressure and automatically starts and stops the pump based on adjustable setpoints. This results in more accurate pressure control, fewer system issues, and improved pump protection compared to traditional setups.
The built-in LCD display and intuitive rotary control provide real-time system visibility and easy programming, while advanced features like dry run protection, rapid cycle prevention, and alarm tracking help protect your pump and extend system life.

Why This is a Major Upgrade Over Standard Controls
Most well systems still rely on mechanical pressure switches, which:
- Wear out over time
- Drift out of calibration
- Offer zero system feedback
The WellZone® eliminates those issues by providing:
- Precision digital pressure control
- Real-time system visibility
- Built-in pump protection logic
- Fewer service calls and longer pump life
Typical Applications
- Residential well systems
- Rural and agricultural water supply
- Low-yield well protection systems
- Replacement for pressure switch + control box setups
