The Kronos series is the most complete and reliable family of peristaltic pumps manufactured by Seko.

The Kronos 50 and 65 series peristaltic metering pumps are equipped with a stepper motor that provides quiet and highly accurate metering (adjustable from 0.01% to 100%).

Kronos has proportional metering and accepts an analogue 4-20 mA signal or a digital frequency signal such as that generated by a pulse-emitting water meter. The pump then doses at a flow rate proportional to this signal, according to the programmed ratio.

The user can also set the pump to constant mode and, in this case, the pump will dose at the programmed flow rate in the presence of an external activation trigger.

The integrated "Pipe Breakage Alarm" mechanism is able to identify chemical leaks inside the peristaltic head and block dosing.

The durable ABS housing with IP65 protection allows the pump to be used even in applications where it may be subjected to small splashes of water or dust.

Thanks to their advanced technology and materials, the different models can reach flow rates of up to 25 l/h (at 0.1 bar) and can dose at back pressures of up to 4 bar with a special HP-San tube.

Kronos' wide range of applications includes:

  • Drinking water treatment (injection of coagulants, flocculants, sodium hypochlorite, lime slurry, acid, bases, caustic soda, activated carbon)
  • Domestic or industrial wastewater treatment
  • Cooling water treatment
  • Chemical treatment, electrolytic treatments (electroplating): addition of degreasing agents, cleaning agents, nickel plating and electroless nickel plating, copper plating and tin plating.

Chemical compatibility: A list of the compatibility of the different chemicals with the different elements of the metering pumps is attached in the Documents section.
