From coal mining to hard rock, AODD pumps are critical pieces of mining equipment used in a wide range of applications to keep mining processes productive and safe.
AODD pumps are used in virtually all forms of mining, including underground, open-pit, dredging, and in-situ processes used for coal, soft/hard rock, precious metals (e.g., nickel, copper, gold, silver), phosphate, and diamond. Of the four types of mining, underground uses the most AODD pumps, but all utilize these pumps regularly. From the slope to the drift, or the face, you will find mining pumps working to keep miners safe.
Extracting minerals and metals from deep within the ground poses many risks, which is why miners need to be able to trust their equipment to get the job done safely. AODD mining pumps offer the extreme durability needed for the mining industry because they:
AODD pumps will not be damaged if they run dry intermittently. With no mechanical seals to fail, pumps running dry are very common, especially in sump dewatering and tanker unloading applications.
AODD pumps can pass solids without damage to the pumps. Ball valve units can handle solids up to nearly 0.75” (19 mm) in diameter, while flap valve units can pass nearly line-sized semi-solids.
AODD pumps require no electricity and can be grounded for safe, reliable operation in explosive environments. This is critical when pumping flammable liquids or when a pump is in an environment where fumes are present.
AODD pumps do not use or require expensive mechanical seals to operate. Instead, reciprocating elastomeric diaphragms and valve checks pull product into the pump then push it out, causing a pumping motion. This concept is extremely forgiving, requiring no balancing or critical alignment.
AODD pumps are known for their versatility and ability to withstand the harshest environments and applications, especially mining operations. An AODD pump’s base mounting options allow it to be used throughout the job site.
Because they only require compressed air to operate, AODD pumps can be easily moved. Carts are commonly used to move the pumps from job to job.
AODD pumps are proven to survive beyond intended handling when tossed, dragged, and crammed into position to rapidly remove fluids or dewater areas.
AODD pumps can be submerged completely and safely with no performance issues. It is important to note that when submerging an AODD pump, you need to pipe the exhaust above liquid level.
With flow rates of up to 280 gpm (1,060 lpm), AODD pumps provide a wide range of flows without costly, sophisticated controls. Standard 1:1 ratio AODD pumps can produce pressures up to 125 psi (8.6 bar). Other ratios, such as 2:1 high-pressure units that can produce pressures up to 240 psi (16.5 bar), are available.
AODD pumps are very simple by design and can easily be repaired on location without extensive training or the need for sophisticated tools. When underground, AODD pump repairs can be made in place as opposed to taking pumps above ground, saving time and money.
