Kronos Series Multi-application peristaltic pumps Kronos is a range of durable and robust peristaltic pumps suited to multiple applications within the cleaning and hygiene and water-treatment industries. Easy to install and requiring minimal maintenance, the whole Kronos range is designed to deliver a “fit and forget” solution that provides convenience and reliability for busy operators. Where hydraulic conditions allow it, the use of a peristaltic rather than solenoid pump allows users to avoid the common difficulties in priming when changing the tank such as possible scaling inside the valves and the rhythmic noise of the working pump, allowing a constant, uniform and non-impulsive dosage of the chemical.
Applications The versatile Kronos Series is suited to multiple water-treatment applications: Drinking water Irrigation systems Cooling towers Swimming pools Wastewater Food & beverage

Kronos 65 The peristaltic Kronos pump with a higher flow rate Among the Kronos pumps, Kronos 65 offers the highest flow rate, up to 25 l/h at low pressures. •
Flow rate: 25 l/h - 0.1 bar
•
Tube: Santoprene
Features •
Direct driven stepper motor
•
Santoprene peristaltic tube
•
PTFE rollers mounted on ball bearings
•
Intuitive digital interface: 7 keys and a 2 x 16 LCD display
•
FM: Proportional dosing with 4 - 20 mA/ pulse input
•
Wall-mounting bracket
•
Kronos 65 is available in the FM model, which features proportional dosage 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 configure the pump in constant mode and, in this case, the pump will dose at the programmed flow rate in the presence of an external activation trigger.
•
The pump is equipped with a powerful stepper motor and is provided with a 65 mm peristaltic head.
•
The integrated “Tube Break Alarm” mechanism identifies chemical leakage inside the peristaltic head and blocks dosage.
•
The durable ABS case with IP65 protection allows the pump to be used even in applications where it may be subject to water splashes or dust.

FM model Proportional dosing: The pump accepts an analogic 4 - 20 mA signal, or a digital frequency signal, and doses at a flow rate proportional to this signal according to the programmed ratio. A pulse-emitting water meter can be connected directly to the digital signal input and, in this case, the pump will dose at a flow rate proportional to that of the water in the pipeline.

Kronos 50 Peristaltic dosing pumps for water and industrial applications Kronos 50 is equipped with a stepper motor that provides infinitely adjustable (0.01 - 100%) and silent dosing. Advanced technology and materials mean the various models can reach flow rates of up to 15 l/h (at 0.1 bar) and can dose at backpressures up to 4 bar with a special HP-San tube. •
Flow rate: up to 15 l/h
•
Backpressure: up to 4 bar
•
Tube: Santoprene - SekoExtra - SekoMed - SekoFort - HP-San
Applications
•
•
Potable water treatment (injection of coagulants, flocculating agents, sodium hypochlorite, lime slurry, acid, bases, caustic soda and activated carbon)
•
Domestic or industrial wastewater treatment and cooling water
•
Chemical treatment, electrolytic (electroplating) treatments: addition of degreasing agents, cleaning agents, nickel electroplating and chemical nickel plating, copper plating and tinning
The digital programming of parameters via keyboard and display ensures a fast set up and final check on the programming data. The easy and intuitive menu enables a simple setting of the various options without the risk of forgetting anything. The internal menu also allows users to check statistics on the life of the tube and the operating life of the pump.
