Description

The Seko HYDRAKOS Water-Driven Pumps 2500 L/h 0.2 to 2% PP/FPM is a non-electric proportional chemical dosing pump designed to provide accurate, repeatable chemical dosing using only water pressure and flow. Manufactured with a durable polypropylene (PP) body and FPM (FKM) seals, this model is ideal for dosing acidic and chlorinated chemicals in water treatment, agriculture, irrigation, livestock, and industrial applications.

Powered entirely by a hydraulic piston, the pump automatically injects chemicals in direct proportion to the water flow, ensuring precise dosing without the need for electricity. The self-priming design, adjustable dosing ratio, and corrosion-resistant construction provide reliable long-term performance while reducing operating and maintenance costs.

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 verify that the chemical being dosed is compatible with polypropylene (PP) and FPM (FKM) wetted materials. For optimum performance, install a filter upstream if the water contains debris and periodically inspect the seals and suction line.
