Froth Pump

A froth pump is a type of pump that is specifically designed to handle frothy or foam-like materials. In the mining industry, froth pumps are commonly used to transport slurry containing frothy ore or coal.

Learn Why Our Froth Pump Have Higher Production and More Uptime

Froth pumps use high pressure to create a froth or foam from the slurry, which helps stabilize the solid particles and prevent them from settling into the bottom of the pump or pipeline. This makes it easier to transport the slurry over long distances without clogging the pump or pipeline.

Froth pumps are typically used in the flotation process, where they are used to create a froth from the slurry that contains valuable minerals. The foam is then collected, and the beneficial minerals are extracted. Froth pumps are also used in tailings treatment, transporting slurry containing waste material and water from the mine to the tailings pond.

Froth pumps are generally more expensive than other types because they require more energy to create the froth. However, they are essential for many mining operations because they can effectively handle materials that would otherwise be difficult to transport.


Types of froth pump in mining:

Several different types of froth pumps are commonly used in the mining industry. These include:

Centrifugal froth pumps: These pumps use centrifugal force to create the froth, and they are typically used in the flotation process to create a stable foam that contains valuable minerals.

Submersible froth pumps: These pumps are designed to be submerged in the slurry and operate underwater. They are typically used in tailings ponds to pump slurry containing waste material and water from the mine.

Positive displacement froth pumps: These pumps use a rotating element, such as a screw or rotor, to move the slurry through the pump. They are typically used in applications where the slurry has a high solids content.

Hydraulic froth pumps: These pumps use high-pressure water to create the froth, and they are typically used in the flotation process to create a stable froth that contains valuable minerals.

Froth pumps are generally classified based on their type of pumping mechanism, such as centrifugal, positive displacement, or hydraulic. The type of pump best suited for a particular application will depend on the specific characteristics of the slurry being pumped and the desired output of the pumping process.

The Eddy Pump is an ideal froth pump due to its completely open design that allows for less air to get trapped while pumping. The Eddy Pump comes in all configurations to fit the application such as flooded suction, submersible, and self-priming.

Why EDDY Solids Handling Pumps are Better

High End Seal Support System
– Explained.


Pass solids from 1-12 inches (rocks, rags, debris). The EDDY Pump’s open rotor design with high tolerances allow anything that will go into the intake to be passed through the discharge without issues.

Tolerance between the rotor and the volute in the 4″ EDDY Pump easily allows the passage of a man’s arm (*see picture below). Compared with the tolerance in a centrifugal pump, the EDDY Pump easily wins. Pump Range spans 1-inch through 12-inch EDDY Pump line, the tolerance ranges from 1-12 inches. 

This translates to a significant amount of solids and debris pass through, without clogging the pump.  To learn more about the technology behind our pumps continue reading Here.
