• Flow rate: 0.4 to 54 L/h
• Back pressure: 0.1 to 20 bar

Power Supply Options

• 100–240 V ac, 50/60 Hz (universal input)
• Model 812 also supports 12 V dc

Materials & Compatibility

• Standard pump head: PVDF (high chemical resistance)
• Optional: PVC head (upon request)

Features & Accessories

• Manual priming for easy startup
• Standard installation kit includes:
• PVDF foot filter & injection valve
• PVC suction tube
• PE delivery tube
• PVC installation kit available (upon request)

Why Metering Dosing Pumps Are Critical in Water Treatment?

Water treatment plants rely on precise chemical dosing to maintain efficiency. A metering dosing pump, like the SEKO Tekna APG600/APG803 AKS603, ensures accuracy, reducing waste and operational costs.

Interesting fact: The global water treatment chemicals market will reach $72.5 billion by 2030 (Grand View Research, 2023). Without proper dosing, plants risk over-treatment (costly) or under-treatment (non-compliant).

How Does an Electromagnetic Diaphragm Pump Work?

Unlike peristaltic pumps, electromagnetic diaphragm metering pumps use a solenoid-driven mechanism for pulse-free, consistent flow. The SEKO Tekna series offers:
✔ Automatic adjustment (0-100% flow)
✔ High chemical resistance (PVDF/PVC options)
✔ Low energy consumption (up to 30% less than traditional pumps)

LSI Keywords: chemical dosing pump, precision dosing, water treatment pump, automated metering, diaphragm pump technology
