DOSING PUMP TECHNOLOGIES

Solenoid, Motor-Driven or Water-Driven

The right dosing pump depends on the chemical, the dose rate, the line pressure and how the dose must follow the process. SEKO covers every step, from a few millilitres an hour of chlorine to thousands of litres an hour of process chemical.

HOW AUTOMATIC DOSING WORKS

The Dose Follows
the Water

Signal → Pump → Injection → Measured result

A solenoid pump pushes a small, exact volume of chemical with every stroke. In constant mode it simply runs at the set rate. In proportional mode a water meter or 4–20 mA signal speeds it up or slows it down to follow the flow. In closed-loop mode a Kontrol controller reads a probe, compares it with the set point, and adjusts the pump to hold pH, chlorine or conductivity steady.

Ranges as published by SEKO for its Water & Industry products. Maximum flow and maximum pressure are usually not available together in the same model; actual output depends on model, back-pressure, chemical viscosity and stroke setting. Hydrakos figures are water flow through the unit at 0.2 – 10% injection.
