Description
The SEKO Tekna Evo AKS803 (AKS803NHP0800) is a solenoid-driven chemical metering pump rated at 20 LPH at 5 bar, supplied and serviced by UV Water Systems as a workhorse dosing pump Oman plants rely on for chlorine, antiscalant, acid and coagulant injection. It is built for the conditions we deal with every day in Muscat: high-TDS feed water, high ambient temperature, and treatment lines that cannot afford an unplanned stop.
Why the Tekna Evo AKS803 works well as a dosing pump Oman sites can trust
Groundwater across the Sultanate frequently runs 500–2,000+ ppm TDS with heavy scaling tendency. That makes accurate, repeatable chemical injection the difference between an RO membrane lasting five years and lasting one. The AKS803 holds its set flow rate under pressure and gives you a clear digital interface to prove what is actually being dosed.
Features and benefits
- 20 l/h at 5 bar output — sized for RO pre-treatment, cooling tower and swimming pool lines, with adjustable stroke rate down to very low doses.
- PVDF pump head, PTFE diaphragm, ceramic ball valves — handles sodium hypochlorite, antiscalant, hydrochloric acid, caustic and peracetic acid without swelling or cracking.
- Constant and proportional dosing modes — run at a fixed rate, or drive the pump from a water meter pulse or a 4–20 mA signal so chemical follows actual flow.
- Batch mode and programmable timer — schedule shock chlorination or periodic sanitisation without an external controller.
- Statistics menu — on-board record of running hours and chemical consumption, useful for AMC reporting and stock planning.
- Level input and low-level alarm — the pump stops and alerts before it runs dry on an empty chemical tank.
- IP65 enclosure, 100–240 VAC 50/60 Hz — wall-mounted, wash-down tolerant, and works directly on Oman’s 240 V supply.
Typical applications
We install this model on RO plant antiscalant and SMBS lines, hospital and hotel water systems, cooling towers, swimming pools, laundry and CIP lines, borehole chlorination for villas and farms, and effluent pH correction. It suits commercial and industrial users; for small residential filtration a smaller model is usually the better fit. If you are comparing options for a dosing pump Oman project, tell us the chemical, the injection pressure and the daily dose and we will confirm the right model.

Scope of supply
Pump unit, foot valve with level probe, injection valve, suction and discharge tubing, wall mounting bracket, and operating manual.
Installation and maintenance
Mount above the chemical tank on a dry wall, within reach of a 240 V socket. Keep suction lift under 1.5 m and use the supplied injection valve on the pressure line. Service kit (diaphragm, valve set, O-rings) is recommended every 12 months under continuous duty, and we stock spares locally in Muscat, so a dosing pump Oman customers buy from us stays serviceable for years.
Warranty and support
Every dosing pump Oman customers order from us is supplied with a 12-month warranty against manufacturing defects. Our technicians handle installation, calibration, commissioning and annual maintenance contracts across Muscat and the wider Sultanate.
