Water and Wastewater Treatment Pumps

Stenner’s variable speed peristaltic chemical feed pumps are well-suited for water or wastewater treatment plants.


Stenner pumps are a good fit for use in municipal water and wastewater treatment plants. Municipalities that supply potable water to residential and commercial sites require treatment of the well or surface water source they use. Well water and surface water need to be disinfected and may need to be treated for problem water issues such as excessive levels of iron, manganese, and hydrogen sulfide which can cause unpleasant odors and staining. In addition, treatment of the return wastewater is required before it can be processed for reuse.


Stenner peristaltic metering pumps are used to inject sodium hypochlorite (chlorine) and other related disinfectants. Stenner pumps are also used to meter solutions for oxidation of iron, manganese, and hydrogen sulfide to prevent staining and rotten egg odor. Additional applications include injection of sodium carbonate or sodium hydroxide for pH control, alum or ferric chloride for coagulation, polyphosphates for corrosion control and fluoride to prevent tooth decay. The Econ T pump has an integral timer with 24 event capability with outputs up to 21.7 gallons per day for dosing solutions in lift stations for reduction of odor, fats and oils.


Installation sites for Stenner peristaltic injection pumps are:

Installation sites are municipal water and wastewater treatment facilities.


Select from a variety of Stenner Pumps to fit the specific application:

  • The S Series is an advanced peristaltic metering pump built to NEMA 4X for demanding applications. Select from multiple operational modes and pump performance indicators that interface with process control systems.

  • Stenner's Classic Series single head adjustable pump offers injection that can be directly into the water line and activated by a pressure switch or controller.  For convenient and quick installations, the Tank System is shipped pre-assembled with the pump and tank.
  • A dry contact water meter is used to activate the pump for proportional chemical feed or if a pump control circuit is unavailable or impractical. The Proportional Injection Pump System, Single or Dual, provides proportional dosing based on the water system’s flow. The components are pre-mounted to a heavy-duty panel to reduce installation time.

  • A proportional feed setup can be tailored to your specific application by purchasing separately the PCM, plastic or stainless steel water meter and the Classic series single head fixed output pump.

  • The SVP Series is a variable speed pump with a manual or automatic control to pace the pump. The SVP4 with the 4-20mA input signal follower provides automatic adjustment of injection rates for demanding applications.

  • The Econ T Series pump provides automatic dosing with 7-day, 24 event control for timed applications.
