LMI C Series Solenoid Chemical Metering Pump

Rugged Housing, Robust Performance

Consistent performance with precision control.

Product Description

The C Series Solenoid Chemical Metering Pump is a positive displacement pump that is designed for precise and reliable chemical dosing. The pump features a rugged, enclosed housing that is resistant to corrosion and harsh environments. The C Series pump is available in a variety of flow rates and pressures to meet the needs of a wide range of applications.


Standard Features
  • Adjustable stroke frequency and the flexibility of up to 1000:1 turndown ratio
  • Manually adjustable stroke length provides accurate pump output adjustment
  • NEMA 4X/IP65 enclosures for protection against corrosive environments
  • Time-tested electronics for reliable, repeatable performance
  • Totally encapsulated electronics for protection against moisture and corrosive conditions. This makes the pump ideal for use in a variety of industries, including chemical processing, water treatment, and food and beverage production.
  • Inputs for low level switch available on certain models
  • Models with external pacing for flow proportional applications
  • Advanced control options for simplified system integration (pulse multiply/divide, 4-20 mA, remote on/off)
  • UL, CUL, NSF 50, NSF 61, NSF 372, CE Certifications
  • The C Series pump uses a positive displacement design to ensure precise and accurate flow control. This means that the pump will deliver the same amount of fluid each time, regardless of the pressure or temperature.
