A submersible pump, also referred to as the submersible water pump, is a pump that can be submerged fully into the water. Every household needs a constant supply of water, and when if the water supply is cut off for whatever reason in the area you live in, you have got to do something. One of the most common solutions is install submersible water pumps for both industrial and home use.
Submersible pumps operate by using a sealed motor to turn an impeller, which is located in the pump housing. The submersible pump may include an intake screen that filters out anything that is too big to pump. As the impeller rotates, pressure pushes the media into the pump inlet, and the impeller speeds up the fluid and forces it into the discharge line.
It is crucial to keep the submersible pumps completely submerged while operating because they are not designed to work out of water. When the pump is submerged, priming the pump is no longer required. Submersible pumps should be used for wells with depth of 25 feet to 400 feet.
There are essentially to major types of submersible pumps that you can select from – a submersible well pump and a sump pump. A submersible well pump is suspended or placed in a water well on a pipe. It could sometimes go as deep as 1000 ft. A submersible well pump us typically powered by alternating current (AC) voltage. However, a smaller well submersible pump for lower depth up to 200 ft. will be powered by direct current (DC) voltage instead.
Another type of submersible water pump is a sump pump. Sump pumps are used to move water from your home basement out of your house. They are equipped with valves that react to rise of water levels or pressure. If the water level is too high, sump pumps will automatically pump excess water out of the basement and away from your home using a discharging mean. This discharging mean is called an effluent, which connects the sump pump to a designated drain.
Submersible pumps are very versatile with many applications. Submersible pumps are used for draining, sewage pumping, general industrial pump and slurry pump. They are also widely used with pond filters.
Some submersible pumps can be lowered down a borehole, and are most typically used for residential commercial, municipal and industrial water abstraction, water wells and oil wells. Other applications of submersible pumps include sewage treatment plants, seawater handling, firefighting, water well and deep well drilling, mine dewatering, offshore drilling rigs, artificial lifts and irrigation systems.
Also, submersible pumps in electrical hazardous locations used for combustible liquids must be designed not to ignite the liquid or vapors.
There are a great many advantages of submersible pumps, including:● Priming-free
Pump self-priming is referred to as the process of removing air from the pump and suction line. Self-priming of pumps can lead to issues such as crack or leak in the suction piping, bad flap valve, and obstruction in the pipes or air release valve. They key advantage of submersible water pumps is that they never have to be primed due to the fact that they are always submerged in the water.● Efficient
Another important benefit of a submersible pump is that it is extremely efficient because it does not require a lot of energy and effort to draw water into the pump. The water is pushed into the submersible pump by water pressure, thereby saving a lot of the energy in the pump.● Versatile
Submersible pumps are extremely versatile in terms of their broad selection in types and models. Some submersible water pumps are able to handle solids while others are especially good in liquids.● Low Noise level
A key advantage of submersible pumps is that they are exceptionally quiet because they are submerged into the water most of the time. You’d never have to worry about the submersible water pumps creating a noise level that could interfere with the life of others no matter where the pumps are installed. Cavitation is never a problem as well because there is no “spike” in pressure when water goes through the pump.
Despite the many great benefits of submersible pumps, there are also some drawbacks, including:● Susceptible to Corrosion
One big drawback of the submersible pumps is the fact that the seals can be corroded with time. And when corrosion takes place, water gets into the motor, rendering it useless until it is repaired. Also, the seal makes it difficult to get into the submersible water pump for repairs.● Lack of Universality
Another downside of the submersible pumps is the fact that there is not one type of pump that can accommodate all applications. For example, a single stage water pump is used for most light and home industrial pump. This entails aquarium filters, sewage pumping, or sump pumps for drainage. On the other hand, a multiple stage water pump is used for underground operations, such as water wells or oil wells. Also, submersible water pumps are limited in a way that they only work in thin liquid like water, or thicker liquid like sewage.
A submersible pump is definitely worth the investment. Not only will it solve your water supply problems, but they also last for many years as long as they are maintained on a regular basis. In most cases, your submersible pumps will be able to run continuously as long as the water source is available. If you do intend to buy a submersible pump, it is always advisable to choose a reliable vendor or supplier regardless of the innate longevity of submersible water pumps. However, accident can happen so it is generally recommended to have your submersible checked up every two years by a professional to make sure that the pump is in perfect shape.
