Stenner S420 Series Variable Speed Metering Pump | S3407

The Stenner S3407 is a heavy-duty, high-pressure peristaltic pump from the S420 Series, designed for precision chemical injection in automated industrial and municipal water systems. This S34 model provides a robust flow rate of 40 Gallons Per Day (GPD) while maintaining the power to inject against system pressures up to 100 PSI.

Built for seamless integration with modern process controllers, the S420 Series is specifically engineered to pace chemical delivery in response to an incoming 4-20mA analog signal. This allows the S3407 to automatically scale its output based on real-time system data—making it an ideal choice for proportional pH control, high-pressure disinfection, and secondary disinfection in municipal water lines.

Key Technical Features

  • 4-20mA Signal Control: Automatically adjusts dosing speed based on an external analog signal, ensuring precise chemical levels without manual intervention.

  • High-Pressure Capability: Rated for 100 PSI, perfect for injecting chemicals directly into pressurized water mains or industrial process lines.

  • Integrated Leak Detection: Features a high-sensitivity sensor system that shuts down the pump and activates an alarm relay if a tube leak is detected.

  • Dual Operating Modes: Easily switch between 4-20mA automated control and manual speed adjustment for total system flexibility.

  • NEMA 4X Rated Housing: The totally enclosed polycarbonate enclosure protects the pump's internal electronics from corrosive vapors, moisture, and dust.

  • Proactive Maintenance: Includes a programmable tube change timer that alerts the operator when the pump tube is reaching the end of its service life.

  • Reliable Peristaltic Design: Self-priming up to 25 feet, it will not vapor lock from off-gassing chemicals and can safely run dry without damaging the motor or head.

  • Tool-Less Tube Changes: Utilizing the patented QuickPro pump head, maintenance is fast and requires no specialized tools.
