Red Lion RL12G05-3W2V Deep Well Pump
Designed for 4-inch wells or larger, the RL12G05-3W2V is a submersible deep well pump rated for 12 GPM at 30 PSI with a 40-foot depth. It features NSF/ANSI 372 certification for potable water and built-ins to extend motor life, including a built-in check valve and suction screen to protect impellers from debris. With a 212-foot shut-off, this model supports deeper well applications while maintaining reliability in three-wire, 230-volt systems.
Red Lion RL12G07-3W2V Deep Well Pump
The RL12G07-3W2V shares the 4-inch well compatibility and NSF/ANSI 372 potable water certification, with a higher 100-foot depth rating at 12 GPM under 30 PSI. Its built-in check valve and suction screen help minimize cycling and debris-induced wear, improving long-term motor life in three-wire, 230-volt configurations and offering an extended shut-off depth of up to 333 feet in suitable wells.
Red Lion RL12G10-3W2V Deep Well Pump
This 1 HP, 12 GPM model expands deep-well capability with a 160-foot depth rating at 30 PSI and 434-foot shut-off. Built for 3-wire, 230-volt systems, it maintains flow stability through a robust suction screen and internal check valve, helping reduce motor cycling and extending service life in demanding well applications.
3 HP Well Pump Control Box (3-Phase)
This weatherproof control box is built for outdoor reliability with a cold-rolled steel enclosure and raised-edge sealing strips. It supports automatic and manual operation, controlled by a float switch in automatic mode to manage water levels efficiently. It includes protections for short circuits, overloads, phase-loss, and locked-rotor events, with a precise AC contactor for stable current switching in three-phase systems.
5 HP Well Pump Control Box (3-Phase)
Designed for heavier loads, this 5 HP control box combines rugged steel construction with a waterproof, raised-edge design. It offers manual and automatic modes, with a float switch to manage water levels and a robust AC contactor for reliable current control. Comprehensive protections include short circuit, overload, phase loss, and locked-rotor, making it suitable for demanding three-phase well pump setups.
Buying Guide: Three-Phase Pump Selection and Setup
- Three-phase compatibility: Ensure the motor and control hardware are rated for 208/230V three-phase operation, or configure a compatible VFD or converter if needed.
- Flow and head requirements: Match pump capacity (GPM) and shut-off head to your water demand and well depth. Deeper wells require higher head capability and more robust motor protection.
- Control box features: Look for automatic float-switch control, short-circuit protection, overload protection, phase-loss protection, and a reliable contactor. Outdoor-rated enclosures extend equipment life in harsh conditions.
- Built-in protections and durability: Corrosion-resistant materials, sealed enclosures, and debris protection (screens, check valves) help reduce maintenance and downtime.
- Submersible vs. above-ground: Submersible pumps are ideal for deep wells; above-ground configurations may suit shallow well or water transfer applications, with appropriate piping and protection.
- System integration: Consider compatibility with irrigation controllers, pressure tanks, and existing electrical infrastructure. A professional electrician can verify wiring, grounding, and motor start/stop sequencing.
- Maintenance and lifecycle: Plan for routine inspection of seals, screens, and electrical connections. Choose models with easily serviceable parts and readily available replacements.
- Cost vs. value: While three-phase gear may have higher upfront costs, efficiency and longevity in larger flow scenarios can reduce operating expenses over time.
- Safety considerations: Use lockable enclosures for outdoor installations and ensure proper clearance for service access and ventilation around control equipment.
For applications requiring robust, three-phase pumping with reliable control, the combination of submersible deep-well pumps and purpose-built three-phase control boxes provides a versatile solution. When selecting equipment, prioritize compatibility with your well depth, desired GPM, voltage availability, and the environment where the system will operate.
