Stenner Pumps

Trusted Chemical Injection Solutions for Water Treatment, Industrial, Agricultural, and Commercial Applications

For more than 69 years, Stenner Pump Company has built a reputation for delivering reliable, accurate, and easy-to-maintain peristaltic metering pumps and chemical injection systems. From residential well water treatment and commercial pools to wastewater treatment, industrial processes, livestock operations, and municipal water systems, Stenner products are designed to provide precise chemical feed solutions across a wide range of applications.

At the core of the Stenner product lineup is proven peristaltic pump technology. Because the solution remains contained within the pump tube and tubing path, Stenner pumps are self-priming, can run dry, handle off-gassing solutions, and resist many of the challenges that affect traditional chemical feed equipment. This design also simplifies maintenance, with many models offering tool-free tube replacement and minimal routine service requirements.

Stenner's diverse product portfolio includes the Classic Series, Econ Series, S Series, S Variable Series, S10P, S128, and complete Proportional Injection Systems. These solutions range from simple fixed-output and adjustable-output pumps to advanced smart metering pumps with 4-20mA control, Modbus communication, leak detection, backup pump capability, and multiple operating modes. Specialized products are available for livestock and poultry water treatment, water meter activated chemical injection, timed dosing, pH adjustment, water disinfection, irrigation, cooling towers, wastewater treatment, and industrial process control.
