Submersible pumps are those pumps that are designed to be able to go under the water. Unlike other pumps that are powered from the engine of the pump, these pumps are designed to work with the help of an impeller. The impeller can regulate the flow of the liquid that is being pumped, in much the same way as a sump pump works. These pumps are extremely useful for pumping water from deep underground wells. They are also used in many residential and commercial applications.
There are two main types of submersible pumps – the electric motor has a driven pump and the hydraulic motor-driven pump. As the names suggest, the electrical motor is connected to a motor that is powered by electrical energy and is placed inside the pump. While the hydraulic pumps are placed inside the pump casing, meaning that the motor has to be housed externally.
While the hydraulic submersible pumps are not very powerful compared to their electric counterparts, they do have the advantage of being extremely long-lasting. The fluid that is pumped with the assistance of this type of pump can last for many years before the pump motor begins to break down. However, the disadvantage of using this type of pump is that it can only handle low pressure. If the pressure rises too high, the motor can get damaged.
The electric submersible pumps are a bit different. While they are not able to handle very high pressures, they are better equipped to cope with lower ones. This is because they are generally made to withstand greater forces on them. These pumps are typically placed inside wells, and they are connected to a timer that controls when the fluid is pumped from the well into the reservoir. Because this can take some time, the timers are usually set to operate automatically.
Some other common submersible pumps are driven by a shaft or a drive water pump. The shaft and drive water pump are most commonly found in borehole pumps. They are more powerful and more efficient than impeller driven pumps as they can pump more fluid with the same amount of energy.
Jet pumps are submersible pumps that work via jets. There are two types of jet pumps – positive displacement and negative displacement. Positive displacement jet pumps use a positive displacement tube that pushes fluid against the walls of a well. This forces the water to travel up and down the good bore at a much faster rate. A negative displacement jet pump works by forcing water against the opposite walls of the well.
Types of Wells
Different submersible pumps are designed to serve different types of wells. The type of pump you will need depends on the volume and depth of your well. There are pumps available that can handle depths below one hundred feet. The amount of pressure and the horsepower of the pump are also related to the well’s pumping capacity. Pumping capacity for wells is a major factor in determining the price of a pump.
Pump Features and Applications
Although submersible pumps come in many different sizes, most are still around thirty-three inches in diameter. For smaller applications, a compact pump is perfect. Smaller pumps can be used in applications where you have limited access or you don’t need a lot of power. Pumps that are powered by electricity are best suited for industrial applications. Pumps powered by gas have greater portability and are best used in residential homes.
There are many factors to consider when selecting a submersible pump’s flow rate rating. If your pump’s flow rate needs are high, then larger pumps are needed. A fifteen-inch pump system with a twelve-foot stroke will not be sufficient. Pumps with a maximum flow rate of twenty-eight inches per minute should be chosen. If your application will see low flows, then a smaller pump is needed. Pumps with a maximum flow rate between ten and twelve inches per minute are ideal.
Pumps can come with an optional safety control device or a float switch. A float switch allows you to set the level of power supplied to the pump so that it never exceeds the maximum power level. Safety control devices are available for use in light, medium and heavy-duty units. The submersible pumps float switch can also be used with power supplies to provide low-voltage warning and to prevent over-voltage.
Submersible pumps can be used for a variety of purposes and are perfect for many applications. Submersible pumps are used in many deep wells applications to control the pressure, as well as for pumping fluids in ditches or channels. Pumps can be attached directly to the well to provide for the draining of a single fluid or the pumping of a large amount of water. Pumps are also used to control and monitor depth for shallow wells that are used for irrigation and other industrial applications.
