Submersible pumps are highly versatile pumps that find utility in a wide range of pumping applications, including those involving high solids content. It is used to move fluid from one place to another while being completely submerged in the fluids that need to be pumped.
However, the challenge for many industries is to choose the right type of submersible pumps for their specific needs. There are different types of submersible pumps out there, each with its own features and capabilities.
From heavy-duty sewage and slurry pumps to handle corrosive and thick solid fluids to dewatering pumps, there are so many options making it challenging for many business owners to choose the right pump for their applications.
To help you select the best submersible pumps, here is a guide to the different types of submersible pumps and what each one does.
What Are Submersible Pumps?
As the name implies, a submersible pump is an electric pump designed to function while fully submerged in mud, water, and drainage. The motor of submerged pumps is completely sealed to prevent leakage of any fluid which can cause the motor to fail.
Submersible pumps are lower in maintenance costs, create less noise in comparison to other pumps, and as it is completely submerged, there is no issue with pump priming.
This type of pump is mainly used to lift fluid from a lower level pressure to a higher level pressure region. The key advantage of a Submersible pump is that it prevents pump cavitation, which occurs due to the high height difference between the pump and the fluid surface.
Submersible Pumps Working
This type of pump is generally positioned vertically where fluids are pumped by the impeller and lose their kinetic energy due to the conversion into pressure energy.
Submersible pumps have enclosed motors with chambers filled with separate oil from the pushed fluid.
The fluid is entered via the impeller’s eye and driven by the pump stages. The other component of submersible pumps is the radial bearings which are responsible for giving radial support to the pump shaft.
Later, the thrust bearing in the pumps absorbs the axial forces created in the pump.
Difference Types Submersible Pumps
Here are some of the common types of submersible pumps:
1️⃣ Submersible Sewage Pumps
Submersible effluent or sewage pumps are used to transfer solid materials. The submersible pumps used in sewage systems are strongly constructed with reliable design to allow heavy solids to pass through without clogging.
