Red Lion RL22G10-3W2V Submersible Deep Well Pump
The Red Lion RL22G10-3W2V is a compact 4-inch, submersible deep well pump designed for 4-inch wells or larger. It features NSF/ANSI 372 certification for potable water, a built-in check valve to reduce rapid cycling and extend motor life, and a built-in suction screen to protect impellers. Operating at 30 PSI, it delivers up to 22 GPM with a 260-foot shut-off. This model is suitable for users who require reliable performance with integrated protections and efficiency in a moderately deep well.
Red Lion RL12G10-3W2V 4-Inch Submersible Pump
The RL12G10-3W2V shares a similar build to the 22 GPM variant but is rated for 12 GPM at 30 PSI, with a depth rating of 160 feet and a shut-off of 434 feet. Built with a built-in check valve and suction screen, this model emphasizes longevity and protection in deeper wells. It is a practical choice for households prioritizing moderate flow with robust debris protection in potable-water applications.
OELFFOW 3 HP Well Pump Control Box
This weatherproof, durable control box is designed for reliable outdoor operation and supports Automatic/Manual modes. It features a cold-rolled steel enclosure, sealing strips to block moisture and dust, and multiple protections including short-circuit, overload, phase-loss, and locked-rotor. The unit’s design emphasizes safe operation in three-phase electrical environments and provides precise control via a built-in AC contactor, improving performance under heavy loads and long run times.
Tuhorse TH3-010-18 Submersible Set (3″ 1 HP)
Compact in diameter, the TH3-010-18 set fits wells of 3-1/4″ ID and larger with a 1-inch NPT stainless steel discharge and 18 stages. It offers a maximum head of 280 feet and a maximum flow of 14 GPM (0-115 feet). This configuration emphasizes deep-well capability and durability in a compact form factor, suitable for households with vertical well constraints and a need for steady performance in moderate-to-deep settings.
Tuhorse TH4-030-11 3 HP 4″ Submersible Set
This 4-inch pump set accommodates larger wells with a 1.5-inch NPT brass discharge and 11 stages. It achieves a cut-off head of 360 feet and can deliver about 30 GPM at 250 feet, with a practical 15 GPM rating. It is well-suited for irrigated landscapes or small commercial applications where higher head and respectable flow are required from a submersible unit.
Tuhorse TH4-015-17 3 HP 4″ Submersible Set
The TH4-015-17 provides a 4-inch well solution with a 1.25-inch NPT brass discharge, a 17-stage design, and a 620-foot head capability. With a rated flow of 15 GPM and a maximum of 25 GPM, it offers versatility for mid-to-large wells and sprinkler systems. The included control box and robust construction support reliable operation in challenging well conditions.
Buying Guide: Key Purchase Considerations For Three-Phase Submersible Wells
- Power availability: Confirm your electrical service is three-phase or convert-ready. Some pump sets and control boxes are designed for 1-phase operation but can be paired with external phase converters or multi-pole contactors for three-phase systems.
- Flow rate vs. head: Higher GPM typically requires greater head capability. Match the pump’s performance curves to your well depth, drawdown, and irrigation or domestic needs.
- Well diameter and glide fit: Ensure the pump diameter fits your well casing. Most options shown use 3-4 inch diameters, with an appropriate stock of discharge fittings (NPT sizes) for the system.
- Materials and reliability: Look for stainless or high-grade steel bodies, corrosion resistance, debris screens, and built-in check valves to reduce cycling and protect impellers.
- Control and protection: A robust control box with protections (short-circuit, overload, phase-loss, locked-rotor) helps prevent motor damage. Automatic float-switch control can reduce labor requirements for water level management.
- Installation and maintenance: Consider ease of installation, the availability of spare parts, and manufacturer warranties. Documentation and service support impact long-term reliability.
- Energy efficiency: Higher-efficiency motors and properly sized pumps can reduce energy consumption and extend motor life, especially in three-phase configurations where startup currents can be significant.
- System integration: If you already have a three-phase panel, ensure compatible wiring, contactors, and safety devices. Some control boxes offer quick integration with existing three-phase feeders.
- Application scope: Domestic water supply versus irrigation or small-scale commercial use will influence the ideal head, flow, and motor power.
