Benefits of Submersible Sewage Water Pumps
Product Updates 10, Dec, 2015
Submersible pump is a mechanical device that can serve multiple purposes and is one of the most extensively used automatic devices. The sump pumps are available from the market in different categories depending upon types of waste water you want pass through the motor, categories like the submersible pump, sewage pump etc.
A submersible pump, also called an electric submersible pump or sub pump, is a pump that can be fully submerged in water. The motor is hermetically sealed and close-coupled to the body of the pump.
The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are more efficient than jet pumps because they don’t really have to spend a lot of energy moving water into the pump; water pressure pushes the water into a submersible pump, thus “saving” a lot of the pump’s energy.
Submersible pumps are used in many applications. Single stage pumps are used for drainage, sewage pumping, general industrial pumping and slurry pumping. They are also popular with pond filters. Multiple stage submersible pumps are typically lowered down a borehole and most typically used for residential, commercial, municipal and industrial water extraction, water wells and in oil wells.
Other uses for submersible pumps include sewage treatment plants, seawater handling, water well and deep well drilling, offshore drilling rigs, artificial lifts, mine dewatering, and irrigation systems and much more.
A submersible pump pushes water to the surface by converting rotary energy into kinetic energy and further convert to pressure energy. This is done by the water being pulled into the pump as an intake, where the rotation of the impeller pushes the water through the diffuser and from there, it goes to the surface.
Also, while the pumps themselves aren’t versatile, the selection certainly is. Some submersible pumps can easily handle solids, while some are better for liquids only. Submersible pumps are quiet, because they are under water, and cavitation is never an issue, because there is no “spike” in pressure as the water flows through the pump.
There are a few disadvantages with submersible pumps, and two of them being with the seals as they corrode with time. When that happens, water seeps into the motor, rendering it useless until it is repaired. Also, that seal makes the submersible pump a bit difficult to get into for repairs.
The other main disadvantage is that one pump does not fit all uses. Single stage pumps are used for most home and light industrial pumping. This includes aquarium filters, sewage pumping, or sump pumps for drainage. Multiple stage pumps are used for anything underground, such as water wells or oil wells. Also, pumps are made to work with thin liquids like water, or thick ones like sewage.
Caution must be used with submersible pumps; they must be fully submerged. The water around a submersible pump actually helps to cool the motor. If it is used out of water, it can overheat.
