Intelligent Metering Algorithm
 
All dosing pumps benefit from our patented power algorithm a fundamental shift in chemical management delivering unparalleled metering precision and performance. Unlike standard pumps that struggle with varying working pressures, our intelligent system dynamically adjusts the solenoid torque in real-time, to ensure a consistent flow rate regardless of back pressure fluctuations or chemical viscosity changes whilst protecting the hardware from over-torque conditions.

Proportional Dosing Pumps
Metering Precision
 
Proportional dosing pumps adjust in real-time chemical metering relative to the flow stream to ensure chemical concentration levels remain constant. They typically achieve this automation using two different types of external signals: a digital pulse from  water meter or an analogue 4÷20mA current signal. The pump operates by counting a specific number of water meter pulses to  inject a fixed volume of chemical, alternatively the current signal regulates the pumps stroke frequency speed.
