Description

The Seko HYDRAKOS – Water-Driven Pumps 2500 l/ph 0,2-2% PVDF/FPM is a non-electric proportional chemical dosing pump designed to deliver accurate and repeatable chemical injection using only water pressure and flow. Manufactured with a PVDF (Polyvinylidene Fluoride) pump body and FPM (Viton®) seals, this model offers outstanding chemical compatibility and is ideal for dosing a wide range of aggressive chemicals, solvents, acids, oxidising agents, and water treatment chemicals.

Powered entirely by a hydraulic piston, the pump automatically injects chemicals in direct proportion to the water flow, ensuring precise dosing regardless of changes in water pressure or flow rate. The self-priming design, adjustable dosing ratio, and corrosion-resistant construction make it suitable for demanding agricultural, industrial, commercial, and water treatment applications

Features:

• Water-driven proportional dosing pump.
• No electrical power required.
• Adjustable dosing range from 0.2% to 2%.

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 confirm that the chemical being dosed is suitable for PVDF and FPM (Viton®) wetted materials. For optimum performance, install an inlet filter where debris may be present and periodically inspect the seals and suction line as part of routine maintenance.
