SEKO Tekna AKS803 Dosing Pump
A higher-flow Tekna AKS size for a suitably low-pressure injection duty. Published family size: 20–110 l/h, with pressure up to 5 bar.
Model selection
AKS803 sizing starts with the operating point
SEKO Tekna AKS803 may be considered when the calculated dosing flow and actual discharge pressure fit the manufacturer-approved performance curve. The published 20–110 l/h and up-to-5 bar envelope is a size range, not confirmation that every flow is available at every pressure.
It may be reviewed for higher-volume reagent addition, make-up or conditioning duties where the injection point remains within the lower published pressure envelope and the suction arrangement supports stable filling.
YiFu Trading supplies dosing pumps as supporting equipment for membrane and water-treatment projects. YiFu does not claim to be an authorized SEKO distributor, and the exact revision, liquid end, connections, accessories and delivery scope must be confirmed before quotation.

Appearance, pump head, connections and accessories vary with the selected configuration. Use approved order documents for final identification.
Published hydraulic envelope
AKS803 flow and pressure range
SEKO's Tekna series brochure is the source for the model-size range below. Final selection requires the current technical data sheet and the applicable performance curve.
| Model | SEKO Tekna AKS803 |
|---|---|
| Published flow range | 20–110 l/h |
| Published pressure range | Up to 5 bar |
| Dosing mode | Constant dosing with an analog interface for the AKS family |
| Configuration status | Liquid-end materials, seals, voltage, connections, stroke data and accessories require order-specific confirmation |
Selection limit: Maximum flow and maximum pressure values must not be combined without checking the approved curve. Chemical compatibility and installation conditions can also change the suitable configuration.
Engineering checks
Information that determines AKS803 suitability
- Required flow profile and expected operating hours
- Maximum discharge pressure including line losses
- Chemical viscosity, temperature and gas-release tendency
- Suction-line diameter, length and tank position
- Connection sizes and injection-point hydraulics
- Duty/standby requirement and maintenance access
When not suitable
Use a different configuration when the duty falls outside the envelope
Do not select AKS803 for injection points above the approved pressure limit or where the minimum required dosing rate is below the controllable range. Suction losses and chemical off-gassing also require special review at higher flow.
A proportional control signal, degassing head, hazardous-area approval, redundancy requirement or unusually viscous or gas-forming chemical may point to another pump configuration even when nominal flow and pressure appear acceptable.
