The Dosatron D3RE3000BPVFHY is a high-precision proportional hydraulic dosing pump designed for accurate micro-dosing of additives, fertilizers, pH correctors and concentrated solutions in water systems, operating without any electrical power.

Powered solely by water pressure, the internal hydraulic motor draws concentrate from an external container and injects it proportionally to the water flow passing through the pump. This ensures a constant and reliable dosing ratio even when flow rate or pressure fluctuate, providing uniform and stable mixing under all operating conditions.

The pump body is manufactured in high chemical-resistance PVDF, ensuring long service life even with aggressive or concentrated products. VF (Viton) seals make this version particularly suitable for acidic solutions and nutrient concentrates. The integrated by-pass allows dosing to be instantly disengaged while maintaining uninterrupted water flow, simplifying maintenance and operational adjustments.

With an ultra-low dosing range of approximately 0.03% – 0.3% (about 0.3 – 3 ml of concentrate per liter of water), the Dosatron D3RE3000BPVFHY is the ideal solution for applications requiring extremely precise and repeatable micro-dosing, such as fertigation, hydroponic systems, pH control and specialized water treatment processes.
