INTRODUCTION
i. Overview:
The ProMix S “TA Series” Polymer Feeder is a skid system designed to control feed water and
polymer and combine them to produce a high quality solution. The system is designed to receive
liquid neat polymer while mixing it with feed water to produce and discharge a quality solution from
the system.
Research in the science of polymer activation indicates that the activation energy must decrease as
the polymeric chain is uncoiled to prevent rupture and hence decrease the performance of the
product.
The mixing of the Polymer Feeder is accomplished
mechanically with three distinct mixing zones
separated by baffles. The first zone consists of a
fast mixing blade that delivers high shear at the
precise point of polymer injection, creating and
immediate dispersion before agglomeration takes
place. The second zone mixing blade induces a
vortex and draws solution down through the center
of the chamber from zone one and forces the
solution outward to the sides and then down into
zone 3. Finally, the third zone mixing blade gently
agitates/blends the active polymer solution before it
exits the chamber through the bottom of the discharge tube.
The ProMix S Polymer Feeder can be enabled in local mode (Simple On/Off operation) or remotely
via a customer supplied dry contact which will Stop/Start the ProMix S Polymer Feeder. A H-O-A
manual switch on the door of the controller permits the user to select the Manual mode by turning
the switch to ‘H’, the Auto mode by turning the switch to ‘A’ or Off by selecting ‘O’. Either mode can
be turned on or off remotely via a customer permissive contact.
In Manual mode the H-O-A switch is placed into the ‘H’ position on the controller door of the ProMix
S Polymer Feeder. The neat polymer pump speed is then adjusted manually using the controller
keypad to change the pump rate from 0 to 100% of the pump rated output. The user must calculate
the required pump speed based upon the polymer concentration desired after manually adjusting
the primary and secondary rotameters for the desired dilution water flow.
In Auto mode the H-O-A switch is placed into the ‘A’ position on the controller door of the ProMix S
Polymer Feeder. This offers a remote control option. In this mode, the controller receives a remote
customer supplied analog 4-20 mA signal to adjust the desired pump speed from 0 to 100% of the
pump rated output. This remote 4-20 mA signal can be scaled at the controller to enhance the
resolution of the pump output control and bias the pump response to the remote signal. As in the
Manual mode the user must calculate the required pump speed to attain the desired dosage.
The ProMix S Polymer Feeder is equipped with all the necessary components for easy installation,
reliable performance and safe operation.
The design incorporates an electric solenoid valve (water inlet), flow meter/switch, manually
adjustable rotameters for primary and secondary dilution flow, peristaltic neat polymer pumps,
microprocessor based controller, manual ball valves, pump calibration column, PVC piping and
components, and polymer mixing chamber mounted on a skid to facilitate proper mixing and
delivery.

ProMinent ProMix ‘S’ Polymer Feeder
ProMix Series_S User 0111 7
1.4 Installation:
1. Unpack and position equipment on sturdy level surface. Fasten to prevent movement.
2. Do not install equipment in areas of extreme heat, cold, dust or humidity. Avoid areas where
objects or fluids can drop from overhead.
3. Units are to be installed as close to the point of application as possible.
4. Inlet pressure is not to exceed 100 psig working pressure.
5. System pressure at the discharge is not to exceed 80% of inlet pressure.
6. Piping Internal to the System:
¾Inspect the piping for breakage. The system may have been jarred during shipping.
¾Check the tightness on all unions. Hand tighten only – no tools. Unions incorporate an o-
ring seal. Ensure that the o-ring is seated properly prior to tightening.
7. Piping External to the System (Reference Appendix A for connection location):
¾Install piping so that connections properly meet system termination points. Do not “stretch”
field installed piping to meet system termination points. Stressed piping will fail!
¾Piping should be at a minimum ¾” to and from the piping on the system.
¾Avoid getting dirt and debris inside the piping during installation. Plug ends of piping with
rags if construction activities are underway. All debris must be flushed from piping before
system start-up.
¾Connect to outlet piping ¾” FNPT from static mixer to associated customer application point.
¾Connect to make-up water inlet piping ¾” FNPT (5 GPM maximum at 100 psig maximum).
¾Connect to Neat Polymer pump inlet piping ½” FNPT.
¾Install ¾” pressure regulator and ¾” y-strainer / basket strainer on the clean make-up water
line if equipment is currently not installed. (Recommended)
¾Allow provisions for draining the system piping. Skid components will require maintenance.
Ensure that chemicals can be evacuated from the skid piping and components for servicing.
8. Electrical Supply Needed for the System:
Note: Review local Electrical Code and follow accordingly.
¾Connect incoming power to skid mounted control panel (120VAC, Single Phase, 15 Amp, 60
Hz). Ensure panel is properly grounded.
¾Check electrical connections to be sure proper voltage is supplied to the system.
¾Power the unit using a dedicated, separate breaker in the local lighting distribution panel.
¾Do not route the AC power in common conduit with variable frequency pump drives.
¾Do not put conduit entries in the top of the control panel. Resulting conduit condensation
and failure to seal may damage controller circuit boards.
9. Set initial Chamber Mixer Motor Overload at approximately 2 Amps above the mixer FLA (Full
Load Amps) rating and adjust as needed during startup to prevent nuisance tripping.
10. Connect Digital Remote Start Functions (note wiring termination points in Appendix B) for
polymer tank level and remote start permissive. Default jumpers should remain in place for any
input not available.
11. Refer to the Stenner SVP0610 Installation & Maintenance Manual regarding pump information.

ProMinent ProMix ‘S’ Polymer Feeder

1.5 Quick Start Guide:
1. After the installation guidelines (Section 1.4) of the manual.
2. Open ball valve on the suction of the pump to allow chemical to flow into the system by
gravity. If the application is suction lift then ensure liquid is present in pump suction.
3. Start up pumps at 100% stroke length and frequency to purge all air and prime the
system. To prime the pump press and hold the PRIME button on the keypad until
chemical is visible in the suction line.
4. Verify motor rotation on Mixing Chamber motor. Normal rotation is CCW.
5. Do not run the mixing chamber motor dry. Damage to the mechanical seal could occur.
6. Close the Secondary flow control valve and adjust the Primary flow control valve to
obtain the flow range required. If additional dilution water is needed adjust the
secondary accordingly.
7. Verify that the maximum polymer injection pump pressure is higher then the system
pressure.
8. Perform pump calibration using drawdown calibration cylinder.
9. Check flow calibration and be sure pump meets or exceeds the rated flow capacity.
Check flows at 100% capacity.
10.In Manual “Hand” mode the neat polymer pump speed is adjusted manually using the
controller keypad to change the pump rate from 0 to 100% of the pump rated output.
11.In Auto mode the controller receives a remote customer supplied analog 4-20 mA signal
to adjust the desired pump speed from 0 to 100% of the pump rated output. This
remote 4-20 mA signal can be scaled at the controller to enhance the resolution of the
pump output control and bias the pump response to the remote signal. A remote start
permissive is also needed. If not available jumper these connections.
12.Confirm proper operation of all instrumentation. For example: Gauge, Rotometer
switch, etc.
13.Input functions checked and simulated (remote start/stop, 4-20mA, etc.).
14.Output functions checked.
15.Test the operation of all remaining circuits.
16.Observe system to assure that nothing looks or sounds abnormal.

‘Calibrate Iin’ matches the % display on the polymer feeder with the remote operator’s %
display.
The underlying 4-20mA level is of less importance than having both of the % displays
( the feeder’s & the remote operator’s) match because the Polymer feed pump operates from
OFF at 0% to maximum ON at 100%.
It’s simpler to calibrate on a % instead of calibrating on a current and making
a non-intuitive 4-20mA loop to 0-100% conversion.
So you don’t need to know that a 32.4% feed corresponds to a current loop @ 9.18 mA.
The factory default scales the 4-20 mA input for 4mA = 0% Pump to 20 mA = 100% Pump.

Sidebar:
There’s a lot of flexibility in the 4-20 mA input scaling & the corresponding pump speed but
most users will leave 4mA=0% and adjust the mA @ 100% to allow 0-100% pump operation
over a narrower range of 4-20 mA input.
For example, if you wish 0-15% of the 4-20 mA input to control the pump from 0-100%
Edit Scale lin @20mA for 6.4mA = 100%
& leave Scale lin @ 4 mA unchanged at 4.0mA = 0%
Setting the mA level below 4.0mA will set the mA level to 4.0mA
Setting the mA level above 21.0mA will set the mA level to 21mA
Setting the % above 100% will set the % to 100%. The % level cannot be set below 0%.
Refer to Appendix A for notes on 4-20mA Input scaling.
If you set % span to zero in error, the pump will turn OFF.
Note that you could make the current loop response reverse acting so that an increasing loop
current will cause a decreasing pump %.

Sidebar:
The feeder defines a failed 4-20mA input @ -1% which is nominally 3.85mA.
(4.0mA – 0.01 x 16.0mA = 3.84mA)
3.85mA allows 4.0mA, a valid pump control signal some headroom prior to a fault response
