Tefen MixRite TF25 Standard 1–5.5% Water Powered Dosing Pump

The MixRite TF25 is a high-flow, water-powered proportional dosing pump designed to inject liquid additives directly into a water line. It is suited to larger irrigation, fertigation, agriculture, livestock, water treatment and chemical dosing applications.

No. The MixRite TF25 operates using water flow and water pressure, so no electricity is required. This makes it suitable for farm, irrigation and remote dosing systems.

The MixRite TF25 operates from 0.2 to 25 m³/h, which is approximately 0.9 to 110 GPM.

The operating pressure range is 1 to 8 bar, or approximately 14.5 to 116 PSI. The system must remain within the pump’s flow and pressure limits.

The MixRite TF25 is available in dosing ranges of 0.1%–1%, 0.3%–2.5%, and 1%–5.5%, depending on the selected model.

The MixRite TF25 uses 2" or 63mm couplings, making it suitable for larger pipework and higher-flow installations.

Tefen recommends using a 120 mesh / 130 micron filter before the pump. For water with high particle content, a 250 mesh / 60 micron filter may be used depending on water quality. The warranty section also notes that a 200 mesh filter must be used in front of the unit for warranty validity.

Yes. The manual notes that the MixRite TF25 can be installed on a bypass line. This is useful where the main system flow is higher than the required injector flow, or where the pump needs to be isolated for servicing.

The suction strainer should be suspended at least 10 cm / 4" above the bottom of the additive tank. This helps prevent insoluble particles from being drawn into the pump and damaging the assembly.

After use, the pump should be flushed by drawing clean water through the suction tube. The inlet filter and additive suction filter should be cleaned regularly, seals should be replaced yearly, and the suction tube should be replaced if damaged by chemical exposure.
