Seko Tekna EVO AKS Series - Solenoid Dosing Pump
The Seko Tekna EVO AKS Series is an analogic dosing pump with a constant, manually adjustable flow rate via a front panel knob. It features two frequency ranges for flow rate adjustment: 0-20% and 0-100% of the maximum flow rate.
Technical Characteristics
- Flow rates: From 0.4 to 54 l/h
- Max back pressure: Up to 20 bar
- Power supply: 100-240 Vac - 50/60 Hz (12 Vdc for AKS 812 model)
- Stroke rate: From 120 to 300 strokes/minute
- Pump head: PVDF (standard), PVC available on request
- Diaphragm: PTFE
- External Enclosure: PP reinforced with fiberglass, IP65 protection degree
- Priming: Manually operated priming valve
- Installation kit: Included
With five different sizes, the Tekna EVO AKS Series covers a wide performance range. The pump's universal power supply allows operation with various voltages. All Tekna series pumps are equipped with a manual priming pump for easier startup. The standard installation kit includes a PVDF foot filter and injection valve, PVC suction tube, and PE delivery tube. An installation kit in PVC is also available.
