SEKO Tekna AKS603 Dosing Pump
A lower-flow Tekna AKS size for a defined constant-dosing duty. Published family size: 4–8 l/h, with pressure up to 12 bar.
Model selection
AKS603 sizing starts with the operating point
SEKO Tekna AKS603 may be considered when the calculated dosing flow and actual discharge pressure fit the manufacturer-approved performance curve. The published 4–8 l/h and up-to-12 bar envelope is a size range, not confirmation that every flow is available at every pressure.
It may be reviewed for lower-flow antiscalant, acid, alkali, oxidant or reducing-agent addition when the chemical program establishes the required dose and the injection pressure is verified.
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.
Published hydraulic envelope
AKS603 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 AKS603 |
|---|---|
| Published flow range | 4–8 l/h |
| Published pressure range | Up to 12 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 AKS603 suitability
- Chemical name, concentration and safety data
- Calculated minimum, normal and maximum dosing flow
- Static and dynamic pressure at the injection point
- Required turndown and manual control expectations
- Suction lift, tank level and priming conditions
- Wetted-material, seal and connection compatibility
When not suitable
Use a different configuration when the duty falls outside the envelope
Do not select AKS603 when the required flow is outside the approved curve, the system backpressure exceeds the selected configuration, or chemical compatibility remains unknown.
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.
