Stenner 85MJH2A2S Peristaltic Pump
The 85MJH2A2S is a variable high-pressure peristaltic injection pump suitable for precise chlorine dosing. It operates from 120V and can handle up to 100 PSI, with a dosing range of 0.8 to 17 GPD. Tube assembly uses a 2 tube configuration and Santoprene tubing with 20 feet of 1/4″ tubing. Best for medium to larger well systems needing adjustable flow and dependable chemical delivery.
Best for: homes with moderate to high chlorine demand or larger well volumes that require flexible dosing. Why selected: strong adjustability and compatibility with various well chemistries. Caution: ensure proper installation to avoid tubing wear and verify electrical wiring meets local codes.
Precision Controls Diaphragm Metering Pump
This diaphragm metering pump delivers up to 31.6 GPD at up to 150 PSI and includes a standard 115V power cord. Its 230V compatibility is possible with hardwiring, making it adaptable for homes with higher chlorine requirements or larger contamination concerns. It’s a solid choice when very consistent dosing is needed and when a robust, electric-powered solution is preferred.
Best for: households requiring higher flow and pressure, or those integrating with a larger well system. Why selected: strong flow capacity and versatility for different electrical configurations. Caution: more complex installation; ensure circuit capacity and proper surge protection.
WELL SAFE Well Sanitizer Kit
The Well Sanitizer Kit is designed for DIY well disinfection and odor control. It includes easy instructions and uses a USDA-grade sanitizer that sanitizes wells and storage systems. It targets rotten egg odors and sulfur smells, and is positioned as a cost-effective maintenance option for routine 3-month treatment cycles.
Best for: homeowners seeking a simple, at-home sanitizer solution to address sulfur odors and taste issues. Why selected: straightforward usage and odor-targeted formula. Caution: effectiveness depends on correct dosing and adequate contact time; not a substitute for professional water testing when contamination risk is high.
Better Water Industries C21044 Chlorine Pellets
These chlorine pellets are designed for use with automatic chlorinators and offer versatility for various applications. They provide chlorine dosing in a pellet form, which can be convenient for certain well systems that integrate with existing chlorination equipment.
Best for: systems already equipped with automated chlorinators or those seeking pellet-form chlorine feed. Why selected: simple integration with common chlorination setups. Caution: ensure the pellet chemistry is compatible with your pump and tubing materials to minimize clogging or buildup.
Stenner 45MJH2A1S Peristaltic Pump
The 45MJH2A1S is a compact peristaltic pump with a dosing range of 0.5 to 10 GPD at 100 PSI. It uses a 2-tube Santoprene profile with 20 feet of 1/4″ tubing and runs on 120V. This model is well-suited for smaller to mid-sized well systems where space is limited but reliable chlorine injection is still needed.
Best for: smaller households or retreat setups with space constraints. Why selected: compact design without sacrificing adjustable flow. Caution: lower max GPD may require more frequent maintenance or scheduling for higher-draw wells.
Buying Guide: Key Considerations for Chlorine Injection in Well Systems
- Dosing needs: Match pump capacity (GPD) and system pressure to your well water flow and contamination risk. Higher GPD and PSI suits larger households or higher chlorine demand.
- Electrical requirements: Confirm voltage compatibility (115V vs 230V) and circuit capacity. Some units support hardwiring for higher voltage setups.
- Tubing and materials: Santoprene or similar tubing with 1/4″ internal diameter is common. Check chemical compatibility with chlorine pellets or liquids to prevent wear or clogging.
- Installation space: Peristaltic pumps are compact but require unobstructed mounting and accessible tubing replacement points.
- Maintenance and parts: Look for readily available replacement tubing, check valves, and seals. Regular checks prevent dosing drift or leaks.
- Odor and taste considerations: If sulfur odors are present, pairing a sanitizer or pellet approach with proper dosing may improve taste and odor.
- Safety and codes: Follow local water safety guidelines and electrical codes. Proper venting and backflow prevention reduce contamination risk.
Frequently Asked Questions
- What is a chlorine injection pump used for in well water?
- How do I choose the right GPD and PSI for my well?
- Are chlorine pellets safe for home use with these pumps?
- Do these systems require professional installation?
- How often should I service an injection pump?
- Can I use a sanitizer kit alongside an injection pump?
Answers: Chlorine injection pumps deliver precise amounts of chlorine into well water to disinfect and reduce odors. Choose GPD and PSI based on daily water usage and well pressure. Pellet chlorine is common but must match the pump’s materials to avoid clogging. Installation ranges from DIY to professional depending on electrical and plumbing complexity. Regular maintenance, including tubing checks and seal replacements, prevents dosing drift. A sanitizer kit can complement a dosing system when used as part of a broader water treatment plan, but verify compatibility with your pump configuration.
