VEVOR Deep Well Submersible Pump, 1HP, 115V
The VEVOR 1HP, 115V deep well submersible pump uses a 6-stage thermoplastic impeller design to deliver up to 37 GPM and a maximum head of 207 ft. The 4-inch diameter suits 4″ or larger well casings, with a 1-1/4″ NPT discharge. Included is a 33-foot electric cord for installations where nearby outlets are available. The pump features a stainless steel frame and components for corrosion resistance and IP68 protection, targeting durability in challenging environments. The copper motor adds reliability, with built-in overload protection to guard against stalling or abnormal conditions. Reminder: operate fully submerged and avoid running dry to protect the motor.
VEVOR Deep Well Submersible Pump, 1HP 230V
This 1HP pump runs on 230V and shares the same 4″ diameter and 1-1/4″ NPT discharge as its 115V sibling. It features the same 6-stage thermoplastic impellers delivering 37 GPM up to 207 ft of head, and includes a 33-foot cord and IP68-rated stainless steel construction. The design emphasizes long-term resistance to corrosion and reliable operation with a copper motor and protective features. As with all submersible pumps, ensure water presence to avoid idle running and protect the motor from overheating.
WASSERMANN 4″ Deep Well Submersible Pump
The WASSERMANN model is a 1HP, 230V submersible pump designed for 4-inch wells. It delivers up to 33 GPM and up to 190 ft of head, with a 10-foot cable included for flexible installation. The pump is built with stainless steel components and a built-in control design that does not require an external control box for operation. This unit is well-suited for home, farm, or small commercial uses where reliability and compact 4-inch compatibility matter.
VEVOR Deep Well Submersible Pump, 3HP
For higher-demand applications, the 3HP, 230V model offers 37 GPM and an impressive 640 ft maximum head. This 4-inch stainless steel pump uses 18-stage thermoplastic impellers to achieve its performance targets and includes a 33-foot cord. The IP68-rated construction ensures durability in wet environments, with copper motor windings and overload protection to prevent damage under abnormal conditions. As with all high-head pumps, verify well depth and water availability to prevent dry running.
Red Lion 4-Inch Submersible Pump
The Red Lion 4-inch submersible model is a compact option with 1/2 horsepower, delivering up to 12 GPM at 30 PSI and a 212 ft shut-off head. It is designed to fit 4-inch wells and larger, with built-in features like a check valve to limit cycling and a suction screen to protect impellers. The NSF/ANSI 372 certification aligns with potable water use and emphasizes safety for domestic installations. Suitable for small to moderate water transfer tasks where space is limited.
Buying Guide
- Well compatibility: Ensure the pump diameter is 4 inches or larger and that the discharge size matches your plumbing (commonly 1-1/4″ NPT).
- Voltage and power: Choose 115V or 230V models based on available electrical supply and desired head/flow. Higher horsepower models (e.g., 3HP) provide greater head for deep wells.
- Head and flow requirements: Match head (ft) and flow (GPM) to well depth and irrigation needs. Deeper wells require pumps with higher head ratings.
- Construction and durability: Stainless steel frames and IP68 waterproof rating favor long-term durability in submerged conditions.
- Motor protection: Look for copper windings and built-in overheat protection to prevent damage from dry running or stalling.
- Cord length: A longer cord (e.g., 33 ft) improves installation flexibility, especially when an outlet isn’t near the well.
- Warranty and service: Consider units with warranties and accessible customer support for maintenance and compatibility checks.
- Installation considerations: Verify suitable well casing size, ensure proper sealing, and follow cooling recommendations to avoid idle running.
- Applications: For irrigation, livestock watering, or bulk water transfer, prioritize models with higher head for longer lift and robust impellers for consistent flow.
In choosing a 4-inch submersible pump, balance power, head, and flow with your well’s depth, water quality, and electrical availability. Durable stainless steel builds paired with IP68 protection provide resilience for long-term installations, while higher horsepower units support challenging tasks and deeper wells. Always follow installation guidelines and safety recommendations to maximize efficiency and lifespan.
