High-Viscosity Reagent Dosing Pump for Mineral Processing
The Electric Differential Pump is designed for reagent dosing and liquid transfer in mineral processing, especially for applications involving higher-viscosity fluids. Its servo-driven diaphragm system allows the suction and discharge processes to be controlled separately, helping provide stable and smooth fluid delivery.
The pump features dedicated slow-speed modes for different fluid viscosities. By reducing suction speed while maintaining the required discharge speed, it can provide more controlled dosing for viscous reagents. Available models provide standard maximum flow rates from 36 to 480 L/h.

High-Viscosity Reagent Dosing
For higher-viscosity reagents, this pump provides 25% and 50% slow-speed modes to adjust the suction process according to fluid characteristics.
At 25% slow mode, the specified maximum viscosity is 3000 mPa·s. At 50% slow mode, the specified maximum viscosity is 2000 mPa·s. This makes the pump suitable for controlled dosing of viscous liquids in mineral processing and other industrial applications.
