What Is A Dosing Pump?
Dosing pumps enable the controlled injection of liquids at specific rates, with a constant flow rate. As Kenfle, we work with Seko, a global brand in dosing pumps. They have gained a strong presence in the international market, particularly thanks to their chemical resistance, automation compatibility, and user-friendly designs.
Seko dosing pumps offer flexible solutions for liquids with varying viscosities and chemical properties, with diaphragm, piston, and solenoid-driven models.
Dosing Pump Operating Principle
Dosing pumps operate on the positive displacement principle. They typically use a diaphragm or piston system to suction and discharge the liquid:
Liquid is drawn into the inlet valve.
The specified volume is drawn into the pump chamber.
The outlet valve precisely injects the liquid to the target point.
The flow rate can be adjusted manually by the user or through automation systems. Seko dosing pumps are fully compatible with modern automation technologies such as 4–20 mA analog inputs, pulse signals, and Wi-Fi/Bluetooth connections.
