Applications
This dosing pump is suitable for:
- Mineral processing and metallurgy
- Flotation reagent dosing
- Precision chemical processing
- Water treatment
- New energy
- Textile dyeing
- Laboratory applications
- Food processing
For mineral processing applications, the pump can be used for precise reagent addition and controlled chemical delivery where stable flow and accurate dosing are required.
Precise Reagent Dosing for Flotation
Accurate reagent addition is important for stable flotation operation. This pump provides adjustable flow control, high repeated dosing accuracy and external control interfaces, making it suitable for reagent dosing applications where dosing consistency is important.
The slow-speed function also allows the dosing process to be adjusted for different fluid viscosities without changing the basic discharge control.
