What You Need to Know About Submersible Water Pumps

Many industries rely on submersible water pumps, which are designed specifically to pump out liquid from a fully submerged state. These portable pumps are ideal for dewatering at mines, construction sites, industrial sumps, and other applications where there is a critical need for efficient dewatering. 

How Do Submersible Water Pumps Work?

Submersible pumps are similar to standard centrifugal pumps in that t utilize a pump casing and an impeller driven by the motor. As the impeller rotates, water is drawn into the pump. The rotating impeller provides consistent suction pressure that sends water through the pump casing and out of the discharge port. A pipe system or hose is generally used to transport the discharged fluid out onto the surface or into another holding well or pond.

Advantages of Submersible Water Pumps

One common problem with centrifugal pumps is cavitation. This may occur in dewatering applications as excess suction head causes vapor bubbles to form inside the pump. They ultimately implode, causing performance issues. The pump can lose suction power, leading to a variety of other major problems. Severe cavitation can even cause potential damage to the impeller and other critical pump system components. 

Submersible water pumps are completely submerged in the water, which prevents cavitation from occurring. This enables the pump to function consistently and provide dependable results during operation. 

Submersible Pump Applications

Submersible pumps are regularly used in sump systems, but can also be used for a variety of other applications:

• Deep Well Dewatering and Pumping

• Contaminated Water Pumping

• Water & Wastewater Treatment

• Petroleum Processing

• Agricultural

• Mining

• Flood Resolution

• Locations with Limited Space or Noise Constraints

• Cooling Towers

• Sewage Lift Stations

• Construction Drainage

In general, it is best to avoid using submersible water pumps in highly corrosive environments or with abrasive liquids. High fluid temperatures and wide-diameter solids can also cause problems for submersible pumps. 

Opt for a submersible water pump when the application calls for water to be pumped from depths of 25 feet or more. Most centrifugal pumps are rated to handle depths of 25-28 feet while submersible pumps can handle heads 50-150 feet (depending on the unit).
