Description

The Seko HYDRAKOS Water-Driven Pump 2500 l/ph 3-10% PP/EPDM is a non-electric proportional chemical dosing pump designed to provide accurate, repeatable chemical injection using only water pressure and flow. Manufactured with a durable polypropylene (PP) pump body and EPDM seals, this model is ideal for dosing alkaline chemicals, sodium-based solutions, and water treatment chemicals in agricultural, industrial, and commercial applications.

Powered entirely by a hydraulic motor, the pump automatically injects chemicals in direct proportion to the water flow, ensuring precise dosing regardless of fluctuations in water pressure or flow rate. Its self-priming design, adjustable dosing ratio, and corrosion-resistant construction provide reliable performance while reducing maintenance and operating costs.

Features:

• Water-driven proportional dosing pump.
• No electrical power required.
• Adjustable dosing range from 3% to 10%.
• Maximum water flow rate of 2,500 l/ph.
• Polypropylene (PP) pump body.
• EPDM seals for excellent compatibility with alkaline chemicals.
• Self-priming operation.
• Accurate and repeatable proportional dosing.
• Injection automatically stops when water flow stops.
• Suitable for fresh, salt, and deionised water.
• Compact, lightweight, and easy to install.
• Low operating and maintenance costs.
• Corrosion-resistant construction.
