Red Lion RL12G05-3W2V 4″ Submersible Deep Well Pump
Three-phase ready configuration with a 4-inch submersible design. This model fits 4-inch wells and up to 40 feet of head at 12 GPM (at 30 PSI) with a 212-foot shut-off. It includes NSF/ANSI 372 potable water certification, a built-in check valve to reduce rapid cycling, and a suction screen to protect impellers from debris. The 3-wire, 230-volt setup makes it suitable for mid-range residential or light commercial applications requiring dependable three-phase integration.
Key Features
- 3.9-inch diameter fits 4-inch wells
- NSF/ANSI 372 potable water certified
- Built-in check valve and suction screen
- 12 GPM at 40 ft head; 212 ft shut-off
3 HP Well Pump Control Box, 220V 10A Three-Phase
This weatherproof control box family is designed for three-phase operation, featuring a cold-rolled steel enclosure and a raised-edge design to block moisture and dust. It supports automatic and manual modes via a switch and float switch to manage water levels without on-site staff. Protective features include short-circuit, overload, phase-loss, and locked-rotor protections, and a built-in AC contactor for controlled current switching. Safety is enhanced by rounded corners and a key-locked enclosure for child safety.
Key Features
- Weatherproof steel enclosure
- Automatic/Manual control with float switch
- Phase-loss and overload protections
Tuhorse 3″ 1 HP Submersible Well Pump Complete Set
This compact set fits slightly under 3 inches and is suitable for smaller wells. It includes a 1-inch NPT stainless steel discharge and 18-stages for efficient pumping with a 280-foot head. Max flow is 14 GPM, with rated 10 GPM, making it a versatile option for shallow wells where a three-phase system may not be required but a three-phase-compatible control approach can be used with appropriate drivers.
Red Lion RL12G10-3W2V 4″ Submersible Deep Well Pump
This 3-wired 230V well pump is designed for 4-inch wells with a substantial 12 GPM flow rate. It includes a built-in check valve to prevent rapid cycling and a suction screen to protect the impellers, supporting dependable operation in potable water systems. It reaches a 434-foot shut-off, enabling deeper well capabilities and robust three-phase style configurations when paired with appropriate controls.
Key Features
- 4-inch well compatibility
- 12 GPM at 30 PSI; 434 ft shut-off
- NSF/ANSI 372 potable water certified
5 HP Well Pump Control Box
Designed for heavier three-phase pumping needs, this control box features a cold-rolled steel enclosure with raised edges to resist rain and dust. It supports automatic and manual modes via a rotary control and includes a float switch for efficient water level management. With comprehensive protections including short circuit, overload, phase loss, and locked-rotor, the unit maintains stable performance under heavy loads and outdoor conditions.
Key Features
- Three-phase protection and control
- Float switch for automatic operation
- Durable outdoor-rated enclosure
Buying Guide: Key Purchase Considerations for 3-Phase Well Pumps
System compatibility and power supply
Confirm whether your site has a three-phase power supply and if the pump is compatible with 3-phase controllers or requires a conversion or soft-start device. Some pumps and control boxes are rated for three-phase operation, while others are designed for single-phase but can be integrated into a three-phase setup with appropriate equipment.
Head, flow, and pressure requirements
Evaluate maximum head (feet) and desired GPM at your well depth. Pumps advertise different performance curves; select models with sufficient shut-off head and pressure at the typical water level you encounter without overloading the motor.
Durability and protection features
Look for weatherproof enclosures, corrosion resistance, and protective features such as short-circuit, overload, phase-loss, and locked-rotor protections. Built-in check valves and suction screens help extend motor life by reducing cycling and protecting impellers from debris.
Control options and automation
Automatic vs. manual operation can impact maintenance needs. Float switches, external controllers, and compatibility with irrigation or sprinkler control systems are important for hands-off operation in remote locations.
Maintenance and certifications
NSF/ANSI potable water certifications, material quality, and warranty terms matter for long-term reliability and safety, especially for drinking water applications.
Installation considerations
Assess pipe diameter, discharge size, NPT fittings, and space for the control box and power connections. Ensure safe electrical work and compliance with local codes for outdoor or well installations.
By weighing these factors—power availability, head and flow needs, durability, control options, and installation constraints—you can choose a 3-phase well pump system that offers reliable performance and steady water delivery for residential, agricultural, or small commercial uses.
