How do submersible pumps work?

Submersible pumps function by using an electric motor that is sealed within a waterproof housing framework. The motor is connected to an impeller. This impeller spins rapidly and creates a low-pressure zone to draw in the fluid around it.

The fluid is then forced out through a discharge pipe at a higher pressure. This enables it to be transported to its intended destination. These are essentially centrifugal pumps. Their hydraulic components include the impeller, pump casing and diffuser element.

They are flooded by the fluid which is handled. This kind of pump does not usually come with a suction line. A pump with the motor arranged above the floor is the vertical shaft submersible pump. Pumps where both the motor and hydraulic components are flooded are known as submersible motor pumps.

Submersible pumps have sealed and airtight motors that are close-coupled to the body of the pump. The key benefit of this kind of pump is that it helps avoid pump cavitation. This is an issue that is linked to a higher elevation difference between the fluid surface and the pump.

Water pumps, especially submersible ones, are crucial in aquaculture and aquarium projects for efficient water circulation, aeration, and dewatering. Here is some handy information on submersible slurry pumps for industries.

While selecting an industrial submersible pump, there are several factors you should take into account. These factors play a crucial role in ensuring that the pump you choose is the right fit for your specific needs. 

Here are some important considerations:

Continuous duty or Intermittent Duty: First thing first, find out what you need. Is it continuous duty versus intermittent duty? Continuous duty motors run non-stop without impacting the motor's life as it's designed to work that way. On the flip side, intermittent-duty-rated motors are designed to work for a short time and require to be cooled down to ambient temperature. 

When it comes to dewatering applications or industrial processes that involve extended operation periods, it is advisable to select an industrial submersible water pump equipped with a continuous-duty motor with a reasonable GPM capacity. To work on the small sump applications or tank fill applications, it is often sufficient to opt for a less expensive pump equipped with an intermittent-duty motor. 

Pump Capacity: Determine the required flow rate and head (vertical lift) that the pump needs to handle. The flow rate refers to the liquid volume, which needs to be moved within a given timeframe, generally measured in gallons (gallons per minute, or GPM). Decide on a max flow rate considering multiple factors such as the volume of liquid to be pumped per minute and the transport distance required.

Pump Type: Consider the type of industrial submersible water pump that suits your application. There are various types available, including dewatering pumps, submersible sewage pumps, and well pumps, each designed for specific purposes.

Selecting the right pump type ensures efficient and reliable operation, minimizing the risk of clogging or damage, and maximizing the pump's lifespan.

Type of Fluid / Level ofSolids Handling : If the pumped liquid contains solid particles, consider the pump's ability to handle solids. Look for features like vortex impellers or grinder systems, or agitator based designs, and hard impeller material depending on the nature and size of the solids present. Clean water is particle-free and hence you can use standard pumps made of cast iron.

These features mitigate the risk of clogging, reduce maintenance needs, and optimize the overall performance and longevity of the pump in applications where solids are present.

Submersible Depth: When selecting a submersible pump, it is crucial to determine the maximum submersion depth that the pump will be subjected to. This depth refers to how far below the liquid surface the pump will be placed. It is important to choose a pump that is suitable for the intended depth and has the necessary sealing mechanisms to prevent water ingress.

Submersible pumps are designed to operate underwater, but they have specific depth limitations. It is essential to check the manufacturer's specifications to ensure that the selected pump is rated for the intended submersion depth.

Pump Power: Power plays a crucial role in pump selection, as different pumps provide varying levels of pressure and GPM to handle fluids with different viscosities or transport them over longer distances. 

Some pumps are specifically designed to handle thicker or more viscous fluids, requiring higher pressure to move them effectively. Additionally, pumps with greater power capabilities are often preferred when the fluid needs to be transported over extended distances. 

Reliability and Maintenance: Lastly, you should also consider the pump's reliability, reputation of the manufacturer, and availability of spare parts to ship. Look for pumps that are easy to maintain and service, as regular maintenance is essential for optimal performance and longevity.
