Description

The Seko HYDRAKOS – Water-Driven Pumps 2500 l/ph 0,2-2% PP/EPDM is a non-electric chemical dosing pump designed to provide accurate, repeatable proportional dosing using only water pressure and flow. Manufactured with a durable polypropylene (PP) pump body and EPDM seals, this model provides excellent resistance to alkaline chemicals and is ideal for water treatment, agriculture, irrigation, livestock, and industrial dosing applications.

Powered entirely by a hydraulic piston, the pump automatically injects chemicals in direct proportion to the water flow, ensuring precise dosing without electricity. The self-priming design, adjustable dosing ratio, and robust construction deliver reliable performance while reducing maintenance and operating costs. The EPDM seal configuration provides excellent compatibility with alkaline chemicals and sodium-based solutions.

Installation:

Install the pump directly into the water supply line following the indicated flow direction. Ensure the water pressure and flow remain within the specified operating limits. Use compatible suction tubing and ensure the chemical being dosed is suitable for PP and EPDM wetted materials. For optimum performance, install a filter upstream if the water contains debris and periodically inspect the seals and suction line.
