Advantages and Disadvantages of Submersible Pumps

Portable Submersible pumps have numerous significant benefits over conventional types of pumps:

Priming is optional. They are self-priming because they run beneath the surface of the fluid being pumped.

Cavitation: Because portable submersible pumps are completely underwater, they are not susceptible to cavitation. This can be an issue with centrifugal pumps and other positive displacement pumps.

Efficiency: When a pump is submerged, there is positive fluid pressure at its inlet. This state can boost efficiency since it requires less energy to transfer fluid via the pump’s liquid channel.

Noise: Because these pumps are submersible, they operate quietly in most situations.

There are some disadvantages too:

Accessibility: Submersible pumps are typically difficult to examine or maintain, particularly in deep well applications. This makes it impossible to do preventative maintenance, and in many cases, pumps are left to operate until they fail and require replacement.

Corrosion: Prolonged exposure to any liquid will cause corrosion. Submersible pumps are commonly utilized to handle corrosive and abrasive liquids. Seals are particularly susceptible to corrosion, resulting in leaks and motor damage. To prevent corrosion, these pumps must be manufactured of corrosion-resistant material, which might be more expensive than other types of pumps with the same capacity.
But this is not the case in Cosmos Dewatering Pumps as our pumps come with anti-corrosive coating which protects them from corrosion. 

Submersible pumps should be inspected as frequently as feasible. This allows for any necessary repairs to be made to extend the pump’s life.

Applications of Dewatering Pump in Hyderabad:

Submersible dewatering pumps in Hyderabad are normally quite dependable and may perform effectively in tough environments. They are built of durable iron castings and coated with epoxy to prevent corrosion.

Here are some of the primary uses for these pumps:

Wastewater: Submersible pumps are commonly utilized in the grit and wastewater business. They are commonly used in pump and lift stations due to their compact size and lower installation costs compared to other pumps.

Sewage treatment: Submersible pumps, such as grinder pumps, are required for this application because they can convey solid material from the pump inlet to the outlet without hindrance. These pumps frequently reduce sewage waste to particles to facilitate handling and downstream treatment.

Sump pumping: Submersible pumps are commonly used to remove water from a low-lying region or pit where water can gather. Examples include eliminating tailings ponds from mining operations and removing water from a building’s basement due to flooding.

Dredging: Port authorities employ these pumps to dredge harbours. They must be specifically constructed to handle liquids with high solid content.

Water wells and boreholes use these pumps to bring water to the surface. CDW submersible pumps are widely used in the oil and gas industry to lift oil from deep wells and bring it to the surface.

Mining uses CDW submersible pumps that differ from those used in the oil and gas industry. They have to deal with harsh conditions because mine water is very acidic and contains suspended particulates.
