Frequently Asked Questions

Selection depends on three primary parameters: (1) the water flow rate in your supply line — match this to the model's flow rate range (e.g. TF5 for 100–5,000 l/h; TF25 for very large lines up to 25,000 l/h); (2) the required dosage percentage — choose the variant with the appropriate dosage range; (3) the chemical nature of the additive — standard PP+FG body for most fertilisers, vitamins and disinfectants; PVDF body when acid concentration exceeds 6%. For livestock applications, always select PO-coded (EPDM seal) variants for compatibility with medications. Contact Bosta's technical team for application-specific advice.
The PO (Poultry) variant uses EPDM seals, making it suitable for continuous contact with medications, vitamins, disinfectants and vaccines dosed via livestock drinking water. It is identified by a red spindle. Standard seals are Viton-based.
No — this is the fundamental engineering advantage of the MixRite proportional mechanism over Venturi injectors and simple electric dosing pumps. The injection ratio is hydraulically determined: for each volume of water that passes through the pump, a fixed proportional volume of additive is injected. This ratio remains constant across the full operating pressure range specified for each model (0.2–8 bar for the 2.5/3.5 series; 1–8 bar for the TF5/TF10/TF25 series). Pressure and flow variations within those limits do not affect dosing accuracy.
Yes, with the correct variant. For acid concentrations in the stock solution up to approximately 6%, the standard CL or PVDF variants with Hastelloy springs and AFLAS seals are appropriate. For concentrations above 6%, Tefen specifically recommends the PVDF-body models (PVDF pump housing + AFLAS seals + Hastelloy spring). These are available in the 2.5 and 3.5 series. Phosphoric acid, nitric acid and sulphuric acid are among the typical acids handled. Always verify the chemical compatibility for your specific acid formulation with Bosta's technical team before installation.
Yes — this is one of the key design characteristics of the entire MixRite range. Because the pump is driven entirely by the water pressure in the supply line, no electrical connection, battery or controller is required at the installation point. This makes MixRite pumps particularly suitable for remote agricultural fields, off-grid livestock buildings, rural water treatment installations and emergency water disinfection in areas without reliable power supply. The pump can be installed directly on the water line or mounted on the chemical container.
The On/Off system allows the suction operation of the pump to be stopped while water continues to flow through the main line. This is useful when dosing is required only at scheduled intervals, or when the pump must be bypassed without shutting down the entire water supply. Tefen offers three On/Off control types: Manual (direct valve on the pump), Hydraulic (pressure-activated) and Electric (solenoid-controlled). The standard "Air Release" model operates without an On/Off system — it continuously doses whenever water flows. On/Off models are available across the 2.5, 3.5, TF5, TF10 and TF25 series.
