Submersible pumps are those types of pumps which can be fully immersed within a tank or other media storage receptacle. The motors of submersible pumps are normally sealed in oil filled cavities and these are protected from contact with the transfer media. The advantage of this type of pump is that it can provide a significant lifting force as it does not rely on external air pressure to lift the fluid. Submersible pumps prevent pump cavitation, a general problem associated with a high elevation difference between the fluid surface and the pump.

Types of Submersible Pump
Depending on where they are used, sumbersible pumps can be of following types:

• Submersible Water Pump
• Submersible Well Pump
• Submersible Fountain Pump
• Submersible Garden Pump
• Submersible Pond Pump
• Submersible Electric Pump
• Submersible Solar Pump
• Submersible Pool Pump
• Submersible Sump Pump

Applications of Submersible Pump
Submersible pumps see widespread use in applications such as:

• Mining
• Pollution Control
• Tunelling
• Municipal Wastewater Plants
• Golf Course/Turf Irrigation
• Agricultural Irrigation
• De-Watering
• Cooling Towers
• Water Parks and Other Fluid Intensive Environments.
• Dredging Application
• Quarrying
• Offshore Oil Duties
• Fluid Storage Caverns
• Thermal Power Station Pumps including Nuclear
• Offshore Marine and Aerospace Refinery, Chemical and Process Plant
• Electric Motors
• Oil and Gas

Features of Submersible Pump

• Submersible pumps are capable of pumping grinding solids of different sizes.
• It can transfer wastewater at large flow rates or high pressures.
• There are four main specifications to consider when selecting between the available submersible pump types (beyond specific pump type or application). These are: maximum discharge flow, maximum discharge pressure, horsepower (hp) and discharge size.
