Industrial pumps are used in the heavy-duty processing of water chemicals, oil and slurry food. Different types of pumps are used for different applications. The most common, though, are standard centrifugal pumps, submersible pumps and self-priming pumps.
A standard centrifugal pump, usually used in water desalination plants, moves fluid through the rotational energy of its rotors or impellers. A submersible pump extracts water from tanks and rivers. This pump can also be used for sewage works.
A self-priming pump functions the same as a standard centrifugal pump but has the capability of clearing itself of air through venting. The construction industry uses a self-priming pump to extract fluid trash.
Self-Priming Pump vs. Standard Centrifugal Pump
On its own, a self-priming pump can clear the air that enters the device. Because of its capacity to self-extract vapour, the pump does not need external assistance to vacuum air. Meaning, the pump works continuously. On the other hand, a standard centrifugal pump needs a foot valve for external priming. Otherwise, it tends to underperform.
Both the self-priming and standard centrifugal pumps can handle muddy and sandy water. A standard centrifugal pump has the capacity to process small debris like leaves and algae, while a self-priming pump can handle solids up to three inches in diameter.
Self-Priming Pump vs. Submersible Pumps
A submersible pump operates while plunged in liquid. But, it cannot be used for flammable liquids like solvents, chemicals and fuels as they can cause the pump to ignite. Meanwhile, a self-priming pump is able to process combustible chemical liquids such as oil.
In the manufacturing, construction and waste management industries, pumps are invaluable. The right pump can make a heavy-duty work easier. Industries should consider using a self-priming pump if necessary. Its venting capacity can reduce work time and limit external support.
