What Is a Tefen Hydraulic Dosing Pump?
A Tefen hydraulic dosing pump operates without electricity. It uses the flow of water as its power source and automatically draws and mixes the chemical concentrate in precise proportions. This makes it ideal for areas where electrical dosing systems are impractical, or where simplicity and reliability are top priorities.
Tools and Materials You’ll Need
Before starting the setup, make sure you have:
- Tefen hydraulic dosing pump (e.g., MixRite model)
- Inlet and outlet fittings
- Suction tube with filter
- Chemical container
- Teflon tape or thread sealant
- Wrenches or pliers
- A clean water supply

Step 1: Identify the Installation Location
Choose a flat and stable spot near your water line and chemical container. Ensure:
- Easy access for monitoring and maintenance
- Good ventilation
- Protection from direct sunlight and harsh weather
Mount the unit vertically for accurate suction and mixing.
Step 2: Connect the Water Inlet and Outlet
- Turn off the main water supply.
- Connect the inlet hose from the water line to the pump’s inlet port.
- Attach the outlet hose from the pump to your dosing line.
- Seal threaded connections with Teflon tape to prevent leaks.
- Tighten all fittings securely—avoid over-tightening.
Step 3: Attach the Suction Tube and Filter
- Insert the suction tube into the pump’s chemical inlet.
- Place the filter end into the chemical container.
- Ensure the filter stays fully submerged to prevent air intake.
This allows the pump to draw the chemical concentrate directly into the water stream.
Step 4: Set the Desired Dosing Ratio
Most Tefen dosing pumps have adjustable ratio settings (e.g., 0.2% to 2%).
- Turn the adjustment sleeve or knob to your required dosage.
- Refer to the model’s ratio chart or user manual for precise calibration.
Correct dosing ensures consistent results without chemical waste.
Step 5: Prime the Pump
Priming removes air from the system and ensures smooth dosing.
- Slowly open the water supply.
- Allow the pump to run until both water and chemical flow evenly.
- Check for leaks or air bubbles in the suction line.
Step 6: Test and Monitor Performance
Let the system run for a few minutes and check for:
- Steady chemical suction
- No leaks or pressure drops
- Uniform mixture at the outlet
Adjust the dosing ratio if needed for accuracy.
Maintenance Tips
To keep your Tefen hydraulic dosing pump working efficiently:
- Rinse the pump with clean water after each use.
- Inspect seals and O-rings regularly.
- Clean the suction filter to prevent clogging.
- Store the pump indoors when not used for long periods.
Proper upkeep extends the pump’s lifespan and ensures consistent dosing.
