DOSING SYSTEMS FOR

SWIMMING POOLS

innovation > technology > future


Dosing systems for

Swimming pools

The quality of the water from a health, aesthetic,

and safety point of view is the main characteristic

in dealing with swimming pools. Seko has made

automatic systems for all needs and applications -

private, semi-public, and public swimming pools.

The automatic systems make it possible to analyse

the water and to suitably pilot dosing units to

maintain optimum water quality. The ease with

which the unit is calibrated and set protects the

work done by both installer and end user, in order

to provide a service that fully complies with all

relevant laws.

Our wide range of measuring and dosing systems

provides a wide range of solutions in terms of

type of measurement, dosing methods, and full

compatibility with the widest range of products

used for treating pool water.

Seko offers its services, acting as a partner that is

capable of designing and developing the solution

that best meets your needs for all swimming pool

applications.

seko group has developed a simple and reliable system made up of an

industrial container that houses the dosing pumps and instruments thus

making installation and maintenance easy. Application of peristaltic

technology - low noise output, easy to use, low maintenance, protection

against siphoning phenomena, avoidance of direct contact with chemical

products.

The system is equipped with a graphic display

subdivided into areas for simultaneous display of

all available measurements.

The removable cover guarantees the accessibility

of the system and also allows:

● Protection of the chemical reagents from

ultraviolet rays

● High visibility display

● IP65 container protects from humid environments

● Multilanguage user-friendly interface. The wide display

allows the creation of graphics for each available measurement via

an internal Data Logger function.

● Mechanics with “flip

STIRRERS

Electrical stirrers with three-phase motor (singlephase

upon request), and fixing flange.

Specifically made for fitting on SER series tanks.

Materials in contact with the liquid:

non-toxic PVC or AISI 316. Speed:1400 or 70 rpm.

TANKS

Slow 70 rpm Fast 1400 rpm

600 mm

800 mm

900 mm

1100 mm

Specifically designed for assembling along with both

electromechanical and electromagnetic dosing units

with stirrers and dosing pumps. Made using a centrifugal

purpose, the mechanical strength of these tanks is

guaranteed. Made of food-grade polyethylene, these

tanks are compatible with almost all chemical products

used in dosing systems.
