  The pump output is not affected as long as the pump is operating within its pressure rating capabilities.

• How do I know what tube size to purchase?

  Below are three options to find the pump tube you need:

  1. • The tube size, represented by a number or letter, is molded on to one of the tube fittings.
     • Find the model from the pump’s data label and reference the output chart in the manual to find the tube size that was shipped in the pump. If you know the pump series the output chart can also be found in the catalog or in the series manual in Literature.
     • Contact us, we’re here to assist you.
• How often should I change the duckbill (where applicable) and the pump tube?

  The pump tube and duckbill are wear parts and replacement is part of routine maintenance. Pressure, run time and the liquid injected are just some of the factors that can affect tube life. Replacing the tube and duckbill before they are worn out is preventative maintenance practice and is recommended by Stenner. The first time the pump tube is replaced is an indication of the approximate life of the tube in that particular application. It is very important to verify that the worn tube was due to normal wear and not an outside contributing factor that could have shortened the tube’s life. Pump tubes and rubber components are considered perishable consumables and are not covered under warranty. For assistance, Contact Us.

• Can Stenner Pumps dispense petroleum based products?

  To pump petroleum based products, order a pump from the Classic Series, S Series S30 model, S420 Series S34 model or S Variable Series S3V model with a Versilon® pump tube. Confirm solution compatibility with the Chemical Resistance Guide before selecting the material. (Note: Not all pumps and tube sizes are available with Versilon® material).

• Can the QuickPro® roller assembly be used in an old style style pump head?

  No, the QuickPro® roller assembly can only be collapsed and expanded by using the QuickPro® tube housing cover. The QuickPro® pump head is included with the Classic and models manufactured after May 2011 and from models in the S Pump Line beginning with S3. The QuickPro® pump head can be identified by the latches on each side of the pump head.

• How do I know if my roller assembly is a QuickPro® roller assembly?

  The rollers arms on the roller assembly are black and can collapse or expand.

  

• Is there suction/discharge tubing available that is UV tolerant?

  Yes, select UV black suction/discharge tubing when building your pump item number.

Classic Series (45, 85, 100, 170)

• Can a Classic series single head pump be converted to a double head pump?

  Yes, the Classic series single head pumps  can be converted to a double head pump. The general steps for the adjustable are: replace the single head main shaft with a double head main shaft; add an innermost pump head (the pump head closest to the motor) with the same tube size as the original pump, and add the extra necessary installation connections. For specific assistance or for converting other models, Contact Us or Email techsupport@stenner.com.

• Can the double head Classic series pump run two #7 pump tubes?

  No, the gear motor does not have enough torque to turn both roller assemblies with #7 pump tubes. The #7 tube is only for the Classic series single head pumps.

• Can the Classic series pump be installed outside?

  Yes, for an outdoor installation, purchase black suction/discharge tubing, which is UV tolerant, and the rain roof. The rain roof slides on to the vertical wall mounting bracket that is supplied with the pump. A pump cover (for pumps that run intermittently) may also be purchased for additional protection.

S Variable Series (S3V, S4V, S5V)

• Can the S Variable Series be controlled by powering them on and off?

  Yes, you may control these pumps by turning on and off mains power to their power source but not more than 4 times per minute.

• Can I use a Stenner PCM to control this pump?

  No, the PCM is designed exclusively for Classic Series pumps.

S Series (S30, S40, S50)

• Why is my pump not responding to the input signal?

  If your pump does not respond to your chosen input signal, reference the pump manual for instruction and check the following on the pump and correct if necessary.

  • Is the wiring is secure and connected to the correct terminals for the input signal?
  • Is the mode that you have selected responds to the signal you are providing?
  • For 0-10VDC or 4-20mA signals, is the the input signal calibration correct in the Calibration menu?

  If this doesn’t resolve the issue then check your signal source to ensure that the intended signal is being sent.

• Can I run more than one pump with the same signal source?

  Yes, for certain signal types and modes:

  • 4-20mA input signal can be wired between the components in a loop to control two pumps for 4-20mA mode.
  • Dry contact signal can be repeated to a second pump or device with an output relay for Pulse and PPM Feed: Flow Switch modes.

Econ FP Series (E10P, E20P)

• Can the Econ FP operate directly from a well pump pressure switch?

  No. The Econ FP requires 120V 60Hz power supplied at all times.  The Econ FP can be controlled by one of three types of signals: a dry contact from a water meter, a 12-24 VAC/VDC signal from a water softener/filter control or a dry contact from a two wire inline flow switch.

   

• Can the Econ FP operate directly from a water softener or filter control valve?

  Yes, the Econ FP pump is compatible with and able to run from the output signals of most of the programmable control valves on the market.

Econ Integrator™ (E10R, E20R)

• Can the Econ Integrator™ use an existing water meter that is wired to a house controller for livestock operations?

  Yes, an internal signal repeater enables the water meter to send the dry contact signal to a controller.

• Will the standby mode interrupt the pulse signal to the controller?

  The standby mode disables the pump. Because of the internal signal repeater, the standby mode does not interrupt the pulse signal to the controller when there is power applied to the pump.

• What type of water meter can be installed?

  The Econ Integrator™ needs a dry contact (pulse) water meter as well as electricity to operate.

• What type of signal comes from the repeater relay?

  The repeater relay provides a dry contact output signal that replicates the dry contact input signal that the pump receives.

• Will the repeater relay transmit a signal when the pump is operating?

  Yes, the repeater will pass through every signal that comes from the water meter. The signal from the water meter will transmit as long as the pump maintains power.

S128 Series (S4M)

• Can the S128 report water consumption to my house controller?

  Yes, using the internal signal repeater relay the pump will repeat the signal from your dry contact water meter to the house controller.  The pump being in standby will not affect this repeated signal from being sent on.

• What type of water meter can be installed?

  The S128 Series works with a dry contact (pulse) water meter.

• What are the available pulse rate settings on the pump?

  The pulse rate settings on the S128 Series dial are I PPG, 10 PPG and 1 PPL. The pump accepts a signal from a water meter providing a dry contact rate of 1 or 10 pulses per gallon, or 1 pulse per liter and proportionally injects directly into the water line at a rate of 1:128 to treat process flow rates up to 10 gallons per minute or 37.9 liters/minute.

Econ Stennicator (E20M)

• Does the Stennicator require power?

  The Stennicator requires 110-120VAC power to operate and is activated by a dry contact water meter.

   

• What type of water meter can be installed?

  The Stennicator works with a dry contact (pulse) water meter.

• Can the output be adjusted?

  The pump output is not adjustable, it injects at a fixed ratio of 1:128 (1 ounce per 1 gallon) based on the water meter pulse rate.

• What are the available pulse rate settings on the pump?

  The settings on the Stennicator pulse dial are labeled I PPG, 10 PPG and 1 PPL. The pump accepts a signal from a water meter providing a dry contact rate of 1 or 10 pulses per gallon, or 1 pulse per liter and proportionally injects directly into the water line at a rate of 1:128 to treat process flow rates up to 2.7 gallons per minute (162 gallons per hour).

• How long is the prime cycle?

  After setting the dial to PRIME, there is a 5 second delay before the pump starts to run. After the delay, the prime setting initiates a 60 second run cycle at maximum speed. At the end of the prime cycle, the pump will stop and will remain stopped until it is set to a contacting rate.

• What does the pump do in Standby?

  When the pump is placed in the standby setting (STBY), it will not dose when it receives a signal from the water meter. The signal from the water meter will continue to repeat.

• What happens if the pump receives a pulse while already dosing?

  If the pump receives a pulse while dosing the pump will not respond or “miss” this pulse.  However, the repeater relay will continue to repeat the signal without issue.

• How can I get more flow?

  The volume can be doubled by using 2 Stennicator pumps to keep pace at higher flow rates. By properly wiring the signal cables each pump will deliver at a ratio of 1:256 (0.5 oz. per gallon) to achieve a ratio of 1:128 (1 oz. per gallon). This will allow a ratio of 1:128 up to flows of 5.4 gallons per minute.

Econ FX & VX Series (E10FX, E20FX, E10VX, E20VX)

• Can I use the Stenner PCM to control this pump?

  No, the PCM is designed exclusively for Classic Series pumps.

Econ T & TD Series (E10T, E20T, E20T_C3, E10T01, E20T01)

• Can the Econ T be programmed to run 24 hours/7 days a week?

  The integral timer provides flexible 7-day, 24-event control capability for varied schedules. Each separate event can run from a minimum of 1 minute to a maximum of 23 hours and 59 minutes within each program.

• What happens if the pump loses power?

  The Econ T & TD Series pumps use an internal battery to maintain the internal time and set timers.  If the pump loses power, when it regains power it will wait until the next “on” time or run if in the power was regained during an “on” time.

• How often should I change the internal backup battery?

  The pump uses a single CR 1220 3V lithium battery to maintain the internal time and should be changed annually.  You have 5 seconds from removing the old battery to installing the new battery, otherwise the internal time and set timers will be lost.

• What is the estimated battery life of the Econ TD Battery Powered pump?

  When using new, premium quality D-cell batteries, the battery life will be approximately 90 days when running once per day for ten minutes at room temperature (75°F) and pumping a low viscosity solution to atmospheric pressure (0 psi).  See the Econ TD Manual for more information.

Econ LD (E10L)

• There is only a few drops coming out of my discharge line, is something wrong?

  The Econ LD was designed for accurate injection of small amounts of liquid.  These low outputs will look like a very small amount as they inject but is perfectly normal.

Proportional Injection System

• Can I reconfigure, or order, the Proportional Injection System with a 1" or larger water meter?

  No, the Proportional Injection System panel is designed to hold the 3/4″ water meter. Two 3/4″ x 1″ bushings are included with all orders for connecting to a 1″ plumbing system.

Tanks

• Are the lids on the Tanks child resistant?

  Yes.

• Is the tank material NSF rated?

  Yes, the Tanks are molded from High Density Polyethylene, approved to NSF/ANSI 61.

• Can all Stenner pumps be mounted to a tank?

  Yes, with the exception of the Classic series double head adjustable models.  However, not all pumps can be purchased prefabricated as a tank system.

• Are the Tanks vented?

  No, however, the lid design helps to prevent a vacuum from developing within the tank. The cap design allows air to enter the tank as the solution is depleted, so a vacuum does not form. It is important that the cap is not over-tightened.

Water Meters

• Do I need my water meter to match my pipe size?

  Water meters should be sized by the system flow rate, not by the pipe size alone, and comply with all city or state regulations. Refer to the manufacturer’s water meter manual for sizing guidelines.

Pump Control Module (PCM)

• Can the PCM run multiple pumps?

  No, the PCM has a single receptacle and is not designed to run multiple pumps. Its current rating is 1.8 amps. A 120V/60Hz Stenner Classic series pump has a load of 1.7 amps or 204 watts.

• When wiring the PCM to a dry contact water meter, is polarity important?

  No, polarity is not an issue with the Carlon water meters that Stenner carries.

• Is the PCM available in various voltages?

  The PCM is available in 120V 60Hz only.

• Is the time range availability adjustable on a PCM?

  The PCM operating time range is factory set according to the specific model selected, but it can be converted to any of the other available time ranges, so it is not necessary to purchase another model. The time range is converted by changing the position of the jumpers on the printed circuit board located under the PCM’s cover. The PCM Manual contains the instructions.

OBSOLETE SVP Series (SVP1, SVP4)

• Is the SVP series pump scalable?

  The SVP is a non-scalable variable speed pump.  The S Series would be the better option if a scalable or invertible 4-20mA response is required.

• When installing multiple SVP4 pumps on a 4-20mA loop, what kind of resistance will each pump take?

  The SVP4 has a signal loop resistance of 128 ohms. Up to five SVP4 pumps can be installed before experiencing a reduction in signal strength.

• When the SVP is in the manual adjustment mode, do the displayed numbers represent the output or the percentage?

  When the SVP is in the manual mode, the numbers on the control panel represent a percentage of the total output capacity of the SVP pump. The output is adjustable from 5% to 100% in 1% increments.

• Can the SVP series be wall mounted?

  There are two ways to mount the SVP to a wall. Secure the motor base directly to the wall (note: the motor cover needs to be removed first), OR purchase the mounting kit (part #MP7000C). The kit includes a bracket that is attached to the wall allowing the SVP to easily slide in or out of the mounting bracket as needed.
