The Seko HYDRAKOS – Water-Driven Pump was created to solve your dosing problems in multiple areas:

Agricultural:

• Firstly it is used to inject fertilizer, pesticides and other additives into irrigation water. It can rely on their equipment to help achieve healthy crops and enjoy improved yields. Poultry farming, pig rearing and rabbit breeding. These versatile systems give breeders peace of mind at all times.

Water Treatment and drinking water:

• Also for every chemical dosing requirement. As a matter of fact this next-generation systems help operators achieve optimal system performances and chemical consumption. As a result SEKO’s water-driven pumps helping operators to cover a multitude of disinfection requirements, ensure managers can maintain the highest standards of hygiene.

Industry:

• From vibro-abrasion, de-greasing and legionella control to mineral dosing and wetting agent injection, these versatile systems cover myriad processes. HYDRAKOS pumps offer high-precision chemical injection solutions for tunnel wash, self-serve and gantry wash systems and many other commercial car wash applications.

How does it work:

• Basically water-driven pump technology is based on a hydraulic motor pump activated only by pressure and water flow. Hence installed directly on the water supply line, the pump operates by using the water flow rate as a source of energy.
• The pressure and flow rate of the water actuates the motor piston which drives a second, product-dosing piston. The product is injected and mixed continuously with the water from the mains supply at the selected dosing rate % (rate of product/water incorporation).
• The dose of concentrated product is directly proportional to the volume of water passing through the pump, independent of variations in the flow rate and pressure of the mains water supply.

Hydraulic Motor:

• The motor piston moves under water pressure, with a system of valves allowing the movement to be reversed.
• Each piston cycle corresponds to a predetermined volume of water which passes through the pump (motor volume). The speed of the motor varies proportionally with water flow.

Dosing Assembly:

• Courtesy of the dosing body’s adjustable capacity, the motor-driven dosing piston continuously injects a fixed volume of product according to the volume of water passing through. Therefore, the operating principle ensures constant proportional dosing independent of fluctuating flow rate and water pressure.
