Stenner pump S10p

Steady Solution Distribution with 10 PPG Mode


An effective and economical way to remove iron without the use of messy and dangerous chemicals or expensive pumps. An air pocket in the upper portion of the tank oxidizes ferrous iron. The single tank design takes up minimal space and the unique media increases the pH of the water as it filters. The existing PH of the water needs to be known. chemical metering pump


  • Activated by dry contact or 12-24 VAC/VDC signal
  • Operates at a set time, speed or flow rate output
  • Tube replacement without tools

Oxidation is necessary to remove unpleasant properties, iron, hydrogen sulfide and manganese, commonly found in ground water in residential and commercial water wells. Iron stains laundry and plumbing fixtures. It can cause a metallic taste in the water and leave deposits that can clog pipes and reduce flow rates. The presence of hydrogen sulfide emits a “rotten egg” odor and has corrosive properties. The presence of manganese in the water will cause black staining of laundry and pipes.

Stenner peristaltic metering pumps accurately inject solutions such as sodium hypochlorite, hydrogen peroxide and potassium permanganate to oxidize undesired chemical elements so unwanted properties may be removed from the water by filtration after adequate contact time in a retention tank

Iron bacteria are small living organisms that naturally occur in soil, shallow groundwater, and surface waters. These bacteria combine iron (or manganese) and oxygen to form deposits of "rust," bacterial cells, and a slimy material that sticks the bacteria to well pipes, pumps, and plumbing fixtures.

The S10P Series is a peristaltic metering pump activated by a water meter, control valve, flow switch or any control equipment that responds to water flow. The control equipment is wired to the pump input terminals to accept a dry contact or 12-24 VAC/VDC signal. The pump runs at a set time, a set speed or a set flow rate output according to the mode of operation selected. The flow rate outputs are up to 30 gallons per day at 100 psi maximum and the turndown is 10:1 and in the 10 PPG mode it is 4:1.

The control panel displays one of four operating modes, Seconds, Flow Switch, Auxiliary or 10 PPG and the percent setting for each. The functions are easy to program on the six button control pad with a backlit LCD window. Two buttons are required for operation and the keypad will automatically lock if it remains idle for one minute.

When using the 10 PPG mode with a 10 PPG water meter, chemical is dispensed ten times per gallon for steady distribution. Also with the 10 PPG mode, the mixing tank can be eliminated for applications not requiring contact time.


Flashing Indicators Prime, Standby, Level, Leak, Change, Signal (excludes 10 PPG mode), Keypad Locked

Leak Detect detects leak, pump shuts off, LEAK flashes on display, relay indication to another device

Level flashes on display when pump receives a dry contact to the level input from a level sensing device detecting low solution in the tank

Signal Repeater repeats the dry contact to another device in the Seconds, Flow Switch and 10 PPG modes of operation

Time Modes

Pump Run Hours running total of run hours, up to 65,000 hours, not resettable
Tube Run Hours total hours the pump tube has been in service
Tube Change Hours set the desired hours for tube to run. When hours are exceeded display flashes CHANGE as a tube replacement reminder
Reset Tube Hours resets Tube Run Hours to zero

Modes Of Operation

10 PPG
The 10 PPG mode is used with a 10 PPG dry contact water meter and with process flows from 0.1 to 14.0 gallons per minute.  The pump runs at the programmed flow rate output for each pulse. The flow rate output is adjustable from 50% to 100% in 5% increments. The connection is not polarity sensitive.

In the Seconds mode, the pump receives a dry contact from a water meter, control valve or any another type of  control equipment that responds to flow. The pump runs for a programmed amount of  time for each pulse. The run time is adjustable from 0.1 to 60 seconds.

In the Flow Switch mode, the pump accepts a dry contact from a 2 wire flow switch and runs at the programmed speed for as long as it receives the contact. The pump speed is adjustable from 10% to 100% in 1% increments.

In the Auxiliary mode, the pump accepts a 12-24 VAC/VDC signal from a control valve or another type of control equipment that responds to flow. The pump runs at a programmed speed for as long as it receives the signal. The speed is adjustable from 10% to 100% in 1% increments.

How to get rid 

S10P Series stenner pumps

Disinfection is necessary around the world to provide biologically safe drinking water to prevent waterborne diseases such as cholera, typhoid and dysentery.

Sodium hypochlorite is a popular form of chlorine that is effective for disinfection and maintains a residual level throughout a commercial or residential plumbing system. Stenner pumps are not affected by off-gassing solutions and can inject chlorine at full strength or diluted with soft water.

* Mixing and retention tanks are required for all bacterial and oxidation applications. dosing pump

It really is not harmful. It is just an irritant. There is one thing for sure if you have it you have iron in your water! So, it depends on how much iron you have. Most iron can be removed with an Iron filter. In my experience only one iron filter really works. It works on the principle of air. Air is forced into the filter when the water touches the air the iron in the water rusts or oxides. Then the iron can be removed by a filter. stenner pumps dosing pump

Stenner Pumps

The pH levels in the system’s water source can impact pipe conditions and impair efficient oxidation. Low pH water can be corrosive to pipes, valves and fittings. High pH water can cause scale to form to clog the pipes.

Stenner’s robust flow activated pump, the S10P, offers a 10 PPG mode to work with a 10 PPG dry contact water meter and process flows of 0.1 to 14 GPM.  With the 10 PPG mode, the S10P delivers steady solution distribution and the mixing tank* can be eliminated for pH correction.

In some systems, oxidizers are injected to break down organic compounds, flocculants are used to form large particles for simple filtration, and acids or alkalines can be introduced for pH adjustment. Stenner pumps offer activation options for injecting sodium carbonate, sodium hydroxide, and acidic products for pH adjustment.
