The SEKO Tekna AKS803 is the solenoid dosing pump Oman water treatment plants rely on for accurate, continuous chemical injection. Rated at 20 L/H at 5 bar, this dosing pump handles chlorine, antiscalant, coagulant, pH correction and disinfection duties across villas, buildings, hotels, factories and municipal water lines. UV Water Systems supplies, installs and services the full SEKO Tekna range across Muscat and the Sultanate of Oman.

Why This Dosing Pump Oman Buyers Choose Suits Local Water Conditions

Groundwater across Oman commonly runs 500-2,000+ ppm TDS with high hardness and variable chlorine demand. Under-dosing leaves membranes and pipework exposed to scale and biofouling; over-dosing wastes chemical and damages equipment. The AKS803 holds its dosing rate steady even when mains voltage fluctuates, thanks to a stabilised multi-voltage power supply that accepts 100-240 VAC.

The PVDF pump head, PTFE diaphragm and ceramic ball valves resist sodium hypochlorite, hydrogen peroxide, peracetic acid and the antiscalants used on RO plants, so the pump keeps working in duties that destroy cheaper units within months.

Features and Benefits

20 L/H at 5 bar output – covers dosing for RO plants, cooling towers, swimming pools and municipal lines from a single pump.
Constant, proportional and batch dosing modes – match the chemical feed to actual flow instead of running the pump flat out.
4-20 mA analogue and digital pulse inputs – connect a water meter, flow sensor or controller for automatic dosing.
PVDF head with PTFE diaphragm and ceramic valves – long service life on aggressive chemicals.
IP65 protection – safe in wet plant rooms and outdoor cabinets under Oman heat and humidity.
Programmable timer and statistics menu – schedule dosing intervals and track chemical consumption per period.
Level probe and low-level alarm input – stops the pump before it runs dry on an empty chemical tank.

Applications for This Chemical Dosing Pump

Chlorine disinfection on borehole and tank water supplies. Antiscalant injection ahead of RO membranes. pH correction with acid or caustic. Coagulant feed on filtration plants. Cooling tower biocide and corrosion inhibitor dosing. Pool chlorination and acid dosing. Laboratory and process water lines.

Pair it with a calibrated dosing tank, injection valve and foot valve for a complete skid, or with a digital TDS and pH meter for on-site verification of dosing results.

What Is Included

Pump unit, suction and discharge tubing, foot valve with strainer, injection valve, level probe connector and operating manual. Chemical tank, mounting bracket and controllers are supplied separately on request.

Installation and Maintenance

Mount the pump above the chemical tank on a flat vertical surface, within 1.5 m of the injection point, with a dedicated 230 V supply. Prime the head before first start and set the stroke rate to the calculated chemical demand. Service the diaphragm and valve kit every 12 months on chlorine duty, or every 18-24 months on antiscalant. Our Muscat-based technicians handle commissioning, dose calculation and annual maintenance contracts.

Warranty and Support

Supplied with a one-year manufacturer warranty against manufacturing defects. UV Water Systems is ISO 9001:2015 certified with 14+ years in the Oman water treatment market, stocking spare diaphragms, valve kits and tubing locally so a failed pump does not stop your plant.
