Why a Self-Priming Pump is More Efficient than a Standard Centrifugal and Submersible Pump

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

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.
