Chemical Feed Pumps

Chemical Feed Pumps Collection: Precision Dosing for Water Treatment

Our Chemical Feed Pumps collection features a carefully selected range of high-quality pumps designed to deliver precise and reliable chemical dosing for water treatment applications. Whether you are managing municipal water systems, industrial processes, or specialized treatment environments, these chemical feed pumps provide accurate flow control and robust performance. This collection includes top models from Chem-Tech, Stenner, and Uni-Dose, spanning various voltages, flow rates, and configurations to meet your specific operational needs.

How Chemical Feed Pumps Work

Chemical feed pumps are specialized metering pumps engineered to inject measured quantities of chemicals—such as chlorine, acids, or anti-scalants—into water streams for treatment purposes. These pumps operate by drawing chemical solution from a reservoir and discharging it at controlled flow rates into the water system, ensuring consistent treatment levels. The dosing accuracy is achieved through positive displacement mechanisms, commonly diaphragm or peristaltic action, which maintain steady flow regardless of pressure variations downstream.

In this collection, the Chem-Tech chemical feed pumps utilize diaphragm pumping technology with models available in both 115 Volt and 230 Volt configurations, offering reliable and consistent chemical feeding. Stenner pumps, known for their high-pressure ratings up to 100 PSI, provide versatile options such as 10 GPD or 17 GPD flow rates powered by 110V or 220V, suitable for a wide variety of treatment systems. The Uni-Dose Series UD chemical metering pump emphasizes precision dosing in a compact design, ideal for moderate flow requirements.

How to Choose the Right Chemical Feed Pump

Selecting the appropriate chemical feed pump depends on several critical factors:

• Voltage Compatibility: Verify the electrical supply available at your site. Our collection includes both 115 Volt and 230 Volt pumps, such as the Chem-Tech 100-030 115 and 230 models, and Stenner pumps available in 110V or 220V options.
• Flow Rate Requirements: Determine the chemical dosing rate necessary for your application. Stenner models provide flow rates of 10 GPD and 17 GPD, while Chem-Tech pumps accommodate broader dosing needs with configurable options.
• Pressure Ratings: Consider the system pressure where the pump will operate. Stenner pumps in this collection handle pressures up to 100 PSI, suitable for most standard water treatment setups.
• Chemical Compatibility: Ensure the pump materials are compatible with the chemicals used. Our Chem-Tech and Stenner pumps are constructed from materials resistant to common water treatment chemicals.
• Sanitary Requirements: For applications requiring sanitary-grade equipment, note the "SAN" suffix on Chem-Tech models (e.g., 100-030 230-SAN), which denotes sanitary construction standards.

Sizing and Compatibility Considerations

Proper sizing of a chemical feed pump is essential to maintain system efficiency and prevent chemical overfeed or underfeed. To size correctly:

• Calculate the total volume of water to be treated and the desired chemical concentration.
• Match the pump’s flow rate to the calculated dosing requirement, factoring in peak flow conditions.
• Review the injection pressure capabilities, ensuring the pump can overcome the hydraulic backpressure of your system.
• Check the tubing and fittings compatibility—many pumps in this collection come with standard 1/4 inch tubing kits for easy integration.

The Chem-Tech feed pumps, including models 100-030 115 and 230 (with or without sanitary options), offer flexible sizing for various treatment scales. Stenner’s 17 GPD and 10 GPD pumps provide standardized dosing capacities with robust construction for long-term operation. The Uni-Dose UD001-238NU-115 is an excellent choice for smaller or medium-scale dosing applications requiring precise metering.

Maintenance and Longevity Tips

Maintaining chemical feed pumps ensures optimal performance and extends service life. Key maintenance practices include:

• Regular Inspection: Check for leaks, tubing wear, and proper pump operation frequently.
• Diaphragm Replacement: Diaphragms in Chem-Tech and Stenner pumps should be inspected and replaced based on manufacturer recommendations or signs of wear.
• Cleaning: Flush the pump and tubing periodically with clean water to prevent chemical buildup and clogging.
• Electrical Connections: Ensure all electrical components, including power cords and switches, remain secure and free from corrosion.
• Calibration: Regularly calibrate the pump output to maintain accurate chemical dosing.

Following these guidelines will help maintain steady chemical feed rates and reduce downtime. The proven durability of Chem-Tech and Stenner pumps, combined with routine maintenance, supports reliable long-term water treatment operations.

Frequently Asked Questions

Q? What voltage options are available for the chemical feed pumps in this collection?
Our chemical feed pumps come with both 115 Volt and 230 Volt options. Chem-Tech offers models such as 100-030 115 and 230 Volt variants, while Stenner pumps are available in 110V and 220V configurations.

Q? How do I know which flow rate I need for my application?
Determine your chemical dosing needs by calculating the volume of water treated and the target chemical concentration. Then select a pump with a flow rate (e.g., 10 GPD, 17 GPD) that matches or slightly exceeds this requirement to ensure proper chemical feed.

Q? Are these chemical feed pumps suitable for sanitary water treatment applications?
Yes, certain Chem-Tech pump models include sanitary-grade versions, indicated by the “-SAN” suffix (e.g., 100-030 230-SAN), designed to meet sanitary requirements for sensitive water treatment systems.
