Diver Slurry Pumps

Diver slurry pumps are a type of slurry pump that is specifically designed for use in underwater or submerged applications. They are typically used in the mining and construction industries to pump slurry, a mixture of water and solids, from one location to another.

Diver slurry pumps are generally submersible pumps designed to be operated underwater. They are typically made of materials resistant to corrosion and wear, such as stainless steel or high- chromium iron, and are equipped with seals to prevent water from entering the pump.

Diver slurry pumps are typically used in applications where it is not practical to use surface pumps, such as when pumping slurry from the bottom of a tailings pond or the bottom of an excavation site. They are also used in the treatment of wastewater, where they are used to pump slurry containing water and solids from a treatment plant to a disposal site.

Different diver slurry pumps include centrifugal pumps, positive displacement pumps, and hydraulic pumps. 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.

Types of Diver Slurry Pumps

Centrifugal slurry pumps: These pumps use centrifugal force to move the slurry through the pump and are typically used for high-flow, low-pressure applications.

Positive displacement slurry 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 and can handle higher pressures.

Hydraulic slurry pumps use high-pressure water to move the slurry through the pump. They are typically used in applications with highly abrasive or corrosive slurry.

The type of diver slurry pump best suited for a particular application will depend on the specific characteristics of the pump and the desired output of the pumping process. Factors to consider when selecting a diver to slurry pump include the type of solids being pumped, the concentration of solids in the slurry, the pressure and flow rate required, and the operating environment. It is essential to choose a pump capable of handling the specific characteristics of the slurry and meeting the required performance specifications.

Diver slurry pumps, like any other type, can experience issues and failures that affect their performance and reliability. Some common problems that may arise with diver slurry pumps include:

Clogging: Diver slurry pumps can become clogged with solids if the slurry being pumped has a high concentration or if the pump's intake is blocked. This can reduce the pump’s flow rate and eventually lead to pump failure.

Wear and tear: Diver slurry pumps are subjected to harsh operating conditions and can experience wear and tear over time. This can lead to parts failure and reduced pump performance.

Corrosion: Diver slurry pumps are often used in underwater or submerged applications and are exposed to corrosive materials. This can lead to the deterioration of the pump's components, affecting its performance and lifespan.

Cavitation: Cavitation occurs when the pressure in the pump's impeller drops below the vapor pressure of the liquid being pumped, causing vapor bubbles to form. These bubbles can collapse, causing damage to the pump and reducing its performance.

Air entrapment: Air entrapment can occur when the air becomes trapped in the pump, reducing efficiency and causing damage to the pump's components.

To prevent these issues, it is essential to properly maintain diver slurry pumps and address any problems that arise as soon as possible. This may involve cleaning the pump, replacing worn parts, and monitoring the pump's performance to identify any potential issues.

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.
