Who is SEKO and what does it make?
SEKO is an Italian manufacturer of dosing pumps and water treatment systems, with more than 45 years of declared activity in the field. The range includes solenoid dosing pumps, peristaltic pumps, motor-driven diaphragm pumps, piston pumps and air-operated double diaphragm (AODD) pumps, alongside control panels for automatic dosing. From the SEKO portfolio we can quote dosing pumps for water treatment, industrial cleaning and chemical dosing, depending on the flow rate and pressure required by the application.
The Tekna series, one of the main ranges, covers a flow rate between 0.4 and 110 litres per hour, at pressures of up to 20 bar, with pump head versions in PVDF, 316L stainless steel, PTFE or ceramic, depending on the chemical compatibility required by the dosed solution. The company also offers dedicated panels, such as those for cooling water treatment or for pH/ORP dosing in swimming pools.
For the Romanian market, SEKO makes sense in water treatment plants, industrial cooling towers and commercial swimming pools, where chemical dosing must be automated and controlled, not done manually by periodic addition of reagent.
What do we supply from the SEKO range?
| Product | Description |
|---|---|
| Tekna series dosing pumps | Solenoid dosing pumps with a flow rate between 0.4 and 110 litres per hour and pressure of up to 20 bar, available with pump heads in PVDF, 316L stainless steel, PTFE or ceramic for compatibility with various chemical reagents. They come in analogue control versions (constant or proportional dosing) and digital, including with direct pH/ORP input for automatic corrective dosing. They are used in water treatment, industrial cleaning and process chemical dosing. For a quotation, the customer must send the flow rate required, the discharge pressure and the chemical being dosed. |
| Kontrol panel for cooling water treatment | Control panel for chemical treatment of cooling tower water, integrating measurement of water parameters and control of the dosing pumps in a single unit. It is used in industrial installations with cooling towers where chemical treatment must be automatically correlated with the actual water parameters, not dosed at fixed intervals. The customer must send the volume of the cooling circuit and the parameters to be controlled automatically. |
| Pooldose panel for pH/ORP | Automatic dosing panel for pH and disinfectant (ORP) in swimming pools, which continuously measures the water and adjusts the dosing of reagents to keep the parameters within the desired limits, without daily manual intervention. It is used in commercial or public swimming pools where water quality must be kept constant. For a quotation, the customer must send the pool volume and the type of disinfectant used (chlorine, other reagent). |

How do we supply SEKO in Romania?
For SEKO we work from the manufacturer's technical documentation; availability and lead time are confirmed in the quotation. SEKO pumps and panels are sourced to order, through EU supply channels, usually within 1–4 weeks of order confirmation. For a correct quotation, the customer must send the flow rate required, the discharge pressure, the chemical being dosed and, if a pump is already installed, its model. We do not promise permanent availability from stock on any SEKO model and we do not confirm the chemical compatibility of a pump head without a case-by-case check with the manufacturer.
We do not offer remote programming of Kontrol or Pooldose panels.
Frequently asked questions about SEKO
What is the SEKO Arkad series and what is it used for?
The Arkad series brings together SEKO air-operated double diaphragm (AODD) pumps, for dosing and transferring chemical liquids, available in several flow rate steps; the J0700 model, for example, has a maximum flow rate of 650 l/min. Choosing the right model depends on the flow rate required and the pressure in the installation.
What is the difference between the Tekna Series and Waredose at SEKO?
The Tekna Series is a family of electromagnetic diaphragm dosing pumps for chemical dosing (0.4–110 l/h, up to 20 bar). Waredose 20 Kompact is a compact automatic detergent and rinse aid dosing unit for professional dishwashers, not a pump for water treatment.
What should be specified when requesting a quotation for SEKO equipment?
We need the type of substance being dosed, the flow rate and pressure required, and the space available for installation. With this data we can indicate the suitable family - Tekna, Arkad or Waredose - and the final quotation is then confirmed on the basis of the datasheets published by SEKO.
Do you supply SEKO equipment in Romania?
SEKO equipment is ordered on request, usually arriving within 1–4 weeks; the range is not kept on the shelf, since each pump family has numerous flow rate variants.
What is the role of the SEKO Kontrol 42 panel?
The Kontrol 42 panel is intended for monitoring and controlling cooling water treatment, managing the dosing of reagents in the industrial cooling circuit.
How do I request a SEKO quotation?
Send the SEKO code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
