Maxspect Turbine Duo 101: Assembly, Installation and Operation.
T Maxspect Turbine Duo is the first expandable water pump available for the freshwater and marine industry, making it an ideal candidate for multi-purpose applications such as a return pump(s), feed manifolds, media reactors, filters, chillers, UV and EVEN another aquarium all with a SINGLE PUMP. Basically it is like having two pumps in one compact package.
The Turbine Duo pump comes in three different models.
The Turbine Duo can be assembled in three separate configurations, which will alter the performance capabilities of the pump, making it the most flexible pump on the market.
Out of the box the Turbine Duo is assembled as a single output, a perfect solution for small sump spaces.
In the single outlet configuration, the 6K model will have a max flow of 1050 gallons per hour, the 9K will have a max flow of 1300 gph and the 12k tops at 1500 gph.
Now, add a couple of parts included in the box and turn the Turbine Duo into a dual output configuration and replace two pumps with one. Feed two returns separately, feed equipment manifolds or multiple aquariums all from a single pump.
In the dual outlet configuration, the 6K model has a max flow of 860 gph per output, NOT the entire pump but from each of the two outputs. The 9K model goes up to 1250 gph per output and the 12K tops at a whopping 1500 gph per output.
Finally, we can add one more adapter, which is also included, and combine the two outputs into one and achieve max flow capacity as a dual input/single output pump.
In this combined outlet format, the 6K reaches a max flow of 1300 gph, the 9K goes up to 2250 gph and the 12K maxes out at a mind-boggling 2400 gph total!
Regardless of which configuration we choose, The Turbine Duo operates nearly dead silent. It uses Sine wave signal for smooth operation and enhanced efficiency compared to most other pumps available today.
In addition to being a solid pump, The Turbine Duo features a low profile controller capable of multiple functions and flows. Add a Maxspect Connect ICV6, sold separately, and the pump can be easily programmed and controlled using the free Syna-G app* available for both iOS and Android.
Installation could not be more convenient. Each Turbine Duo comes with a complete set of adapters and accessories for a simple install right out of the box no matter what configuration you choose. Install the barbed adapters if you want to use flexible tubing or use the slip adapter to connect to hard PVC.
The Turbine Duo is for submerged operation only and cannot be run out of water.
The pump comes preconfigured as a single input, single output. Here is how to upgrade the pump to a dual output configuration to take advantage of twin propellers.
You will need a:
- Philips head screw drive
- Solid clean surface to work over.
Grab the base and pull it away from the pump.
On side B, twist the black cap clockwise and lift off.
On Side A, turn the blue volute counterclockwise and lift off to expose the propeller.
Although not necessary, I suggest removing the large seals from each side of the pump and place them to the side.
On side B there is the nut embedded within the center of the black end cap.
On Side A is a propeller with a Philips head screw in the center.
While holding the black cap on side B unscrew side A with a Philips head screwdriver counter clockwise till the nut threads off. Please be carful when handling the small nut. Remove the black cap on side B by pulling it away from the pump.
With the Black cap removed, line up the flat sides of propeller B with the flat sides on the shaft and push on. Secure the propeller to the shaft by inserting the nut into the center of side B and wile holding into position, fasten the screw head on side A by turning clockwise. Be careful not to over tighten and damage the pump.
Grab one of the large seals and put in its corresponding place on side A. Then take volute A and place it on its side and turn clockwise to lock in place. We do this once more with side B but turn the volute counterclockwise to lock in position. Each of the outputs can be oriented to flow horizontally or vertically.
Reinstall the pump base to complete the assembly.
How to Plumb the Turbine Duo Intake
We can direct plumb the intake using the supplied slip PVC fitting or use the intake screen to prevent anything from entering the pump and possibly damaging it.
The Turbine Duo is for submerged operation only and cannot be run out of water.
Once the pump has been installed, it is time to mount the controller. Choose a location that is away from heat, excessive humidity and NEVER mount the controller over open water.
Affix the rear-mounting frame to a flat surface such as the wall or outside your aquarium stand. Please, be sure that the cable reaches the pump and the cable connections have proper drip loops to prevent any components from getting wet.
Finally, connect the PSU to the power outlet and run the pump for the first time.
Turbine Duo Controller and Features
The controller box has two buttons, a dial, and a display.
The Switch Mode button allows you to switch between each of the available options while, the control dial lets you toggle between the different flow speed and pulse frequency.
To begin operation, we need to set up the system clock, minimum pump speed and optional battery settings.
To access setup, Press the Power and the switch mode button simultaneously and release.
Begin by entering the controller’s internal clock. Rotate the dial to the correct hour and press the dial in to set up minutes.
Then press center dial to set the pumps minimum head flow.
Minimum head flow is the flow speed just above the point where the down pressure from water in the plumbing is equal or greater than the pressure of the pump pushing water upwards. Basically it is a point where water is retained in the plumbing and your sumps water levels are not often affected.
The minimum head flow is different for every system as it’s based on each tanks individual setup. The total length of the plumbing, the numbers of corners or splits all affect the total flow output of the pump. When the downward pressure is the same as the upward pressure, the water will stop moving. The pump will run but no water moves up or down. It is up to each individual to test and determine the minimum set speed for your application to ensure that water keeps flowing upwards. Enter that minimum speed here.
Press the dial once to save and continue to set the optional battery mode speed.
Press the dial once to save and continue to set the optional battery mode speed. Here you can specify the speed the pump will run when power is lost. Be sure to set the speed no less than your minimum head flow speed.
The second available flow mode is Pulsing. Here you can set the pump to automatically switch on and off at different preset times to recreate a surging effect.
In Random Mode you set the max speed and the controller will randomly select and run different modes to create an unpredictable flow pattern.
Advanced Pulsing Mode is similar to pulse mode as the pump will turn ON and OFF at a set frequency. The difference is that each time the pump turns ON and OFF, it will increase the speed until it reaches the maximum speed we specified. Then, it will gradually slow down and start the cycle again. This mode is great for closed loop flow systems.
In all applications we suggest you start with Constant Speed till you have a good understanding of the pumps capabilities and needs for unique flow patterns.
The Turbine Duo can be controlled directly with its controller or via Wi-Fi using the required, but not included, Maxspect Connect ICV6 controller and the free Syna-G app available for both Android and iOS.

In addition to the flow modes, the controller comes with two Operational Modes. Manual Mode that allows you to configure a single flow mode to run 24/7 and, Automatic Mode, which allows you to create a customized flow regimen in a 24-hr continuous cycle.
To setup manual mode, press and hold the power button for 4 seconds to turn the controller ON.
Now press and hold the Switch Mode Button for 4 seconds until the controller displays an M letter.
If the controller displays an A letter instead, then press and hold the Switch Mode button again until the letter A switches to M.
Now press and release the Switch Mode button once again to enter the setup screen.The screen will flash a gear icon indicating that the controller is in setup mode.
Rotate the dial clockwise to select the desired flow mode for your pump.
Once the controller flashes the desired flow icon, press the center dial once to save and continue to the next available option.
Once you have reached the desired flow speed, press the center dial once to save and move on to the next available variable. Continue this process through all required variables.
Automatic Mode is set up very similar to manual mode. In fact, the only difference is that you can select how long a particular setup will run.
To select automatic mode, press and hold the Switch Mode button for 4 seconds until you see an A icon on the right side of the display screen.
Press and release the switch mode button once again to enter setup mode. The display will now flash a settings icon.
As you enter setup mode, you will see the left side of the display flash a number 1.
Next to the number one you will also see a time stamp set to zero. The number 1 indicates a set point in the scheduling. The controller can have up to 24 different set points. The time stamp indicates the STARTING point of such set point.
For example, I am going to create a 3-point 24 hour schedule. I want the first set point to run a pattern from 8am to 2pm. Then I want a new pattern to run from 2pm to 10pm and I want my last pattern to run from 10pm to 8am the next day.
You will need to set the first number to 1 with a time stamp of 8am
Then, proceed to set the pump up the same way we set it up in manual mode.
After setting up all the variables for point one and you have pressed the center dial to return to the flashing number 1
Carefully turn the dial clockwise until the number one changes to number 2.
Set up point 2 to 14:00 and following the same sequence as before, create point 3 with a starting time of 22:00.
Once you have created all the desired set points, go ahead and press the Switch Mode button once to return to the main screen.
The left side of the display will confirm the new program and the gear icon will fade away.
The controller also comes equipped with a feeding mode. When activated, the controller will slow down the pump to set flow and time length. Once the feeding time has expired, the pump will resume its previous mode of operation.
To set up feed mode we must first activate it by pressing the power button on the controller.
Then press the switch mode button once and rotate the dial to set the feed time from 5 all the way up to 60 minutes.
Hit the center of the dial once to change to the feed mode flow setting.
Here we adjust the flow to the desired feed flow. Remember to keep that flow intensity higher than your Minimum Head Flow.
