Description
The Seko HYDRAKOS Water-Driven Pump 2500 L/h 0.2-2% PVDF/EPDM is a non-electric proportional chemical dosing pump designed to provide accurate and repeatable chemical injection using only water pressure and flow. Manufactured with a PVDF (Polyvinylidene Fluoride) pump body and EPDM seals, this model offers outstanding chemical resistance and is ideal for dosing alkaline chemicals and many water treatment solutions.
The pump operates without electricity by using a hydraulic piston driven by the water flowing through the system. As water passes through the pump, it proportionally injects a precise amount of chemical, ensuring consistent dosing regardless of fluctuations in water flow or pressure.
Its self-priming design, adjustable dosing ratio, and corrosion-resistant construction make it an excellent solution for agricultural irrigation, drinking water treatment, industrial processing, livestock farming, cooling towers, car wash systems, and chemical injection applications.

Installation:
Install the pump directly into the water supply line following the indicated flow direction. Ensure the operating water pressure and flow remain within the recommended limits. Use compatible suction tubing and ensure the dosed chemical is suitable for PVDF and EPDM wetted materials. For optimum performance, install an inlet filter where debris may be present and inspect the seals and suction line periodically as part of routine maintenance.
