CNSME 4RV-AF Vertical Froth Pump – Heavy-Duty Solution for Frothy Slurry Applications

The CNSME AF series froth pumps are specifically designed to improve the handling of frothy slurries commonly encountered in flotation processes. The 4RV-AF model features a cantilever vertical design and a conical tank with a tangential inlet, creating an open vortex that effectively separates air from the slurry, resulting in higher efficiency and continuous, smooth operation.

Key Features
Integrated Pump & Tank Unit for flexible plant layout.

Open Vortex Formation at the sump reduces air locking, ensuring uninterrupted performance.

Cantilever Shaft Design eliminates the need for submerged bearings or shaft seals.

Wear-Resistant Wet End Components for extended operational life in abrasive conditions.

Grease-Lubricated Anti-Friction Bearings support the shaft for low maintenance and high reliability.
