Water supply of a country cottage or summer cottage is a hot topic for most owners of this property. In one of the articles, we described the design and operation of surface pumps. Now we will take a closer look at submersible pumps.
All household submersible pumps are immersed in water, either partially or entirely. This device allows you to pump water from a considerable depth, including water from wells. Depending on the modification of the pump, its immersion depth can reach three hundred meters. Therein lies its main advantage. The disadvantage of submersible pumps is the relatively difficult maintenance of this device.
Submersible pump device
All submersible pumps have a durable sealed housing, which serves to protect the pump mechanism from corrosion processes. Household pumps are divided into two main types:
- centrifugal,
- vibrating.
If we talk about vibration submersible pumps, they pump water through vibration. In this regard, it is better not to lay these devices close to the sandy bottom, since vibration will be transmitted from the pump to the walls and bottom of the well, which will cause sand to rise. As a result, in the water that will come to your house, there will be a significant admixture of sand.
In turn, submersible centrifugal pumps pump water by rotating a wheel equipped with blades. Due to the centrifugal force of the wheel, water is thrown to the walls of the pump and then sent to a special chamber. When the pressure increases, water from the chamber is supplied to the outlet.
Classification by purpose
The design of a household submersible pump affects its scope. Today, well or water pumps are produced, as well as borehole, fecal and drainage pumps.
- Water pumps are used for pumping clean water, which does not contain all kinds of impurities such as algae, sand or silt. In this regard, it is better to place these devices no closer than a meter from the bottom of the reservoir. A submersible water pump is mainly used for pumping water for an individual water supply or for watering gardens.
- Well pumps, due to the fact that they have a water intake hole at the bottom, are able to function even with partial immersion.
- Drainage submersible pumps are designed for pumping both contaminated and clean water. These pumps are not afraid of algae, sand, or small particles of debris. By means of drainage submersible pumps, it is possible to pump water for the purpose of watering vegetable gardens from the nearest ditch, as well as pump out water accumulated during the spring floods from the basement or from the cellar. In addition, these devices are well suited for taking water from any open reservoir, as well as pumping water from the pool.
- Downhole submersible pumps are used to draw water from great depths (up to 300m). The design of this type of pump allows you to work with water in which there are mechanical impurities, as well as with sandy or limestone water. Features of functioning also determine the shape of borehole pumps - they all have a small diameter and an elongated shape. The disadvantages of downhole submersible pumps are their high cost, as well as the complexity of installation. Speaking about the advantages of these devices, it is necessary to note their high level of pressure force and performance. That is, they are able to provide water to a country cottage even when the water source is quite far away.
- Fecal submersible pumps are used for pumping sewage. The design of this type of pump allows the passage of larger particles than a drainage pump. For this purpose, fecal pumps are equipped with a special cutting nozzle. These submersible pumps are used in cases where it is not possible to organize a gravity sewer system. Fecal pumps do not need to be pulled out - they can be in the pit for a long time, continuing to function.
Submersible pump selection criteria
It is necessary to select a submersible pump taking into account the required level of performance and pressure. These parameters should be pre-calculated.
Performance. To calculate it, it is necessary to determine the volume of water consumption. According to SNiP, watering one meter square lawn requires three to six sheets of water per day, and per person daily water consumption is 200 liters.
Head. The head is the height to which the pump can lift water. To calculate the required head, you need to know the height to which the water will rise, as well as the length of its horizontal path. It is believed that one meter of pressure is spent on ten meters of horizontal path.
Submersible Pump Manufacturers
The products of the Italian company Awelco have been pleasing consumers with their impeccable quality characteristics for quite a long time. Awelco has been producing pumping equipment for over twenty years. All submersible pumps manufactured by this manufacturer are manufactured using the most modern technologies. It is also gratifying that the prices for these products are quite reasonable.
Wilo is another German company producing submersible pumps. This company specializing in the manufacture of heating, industrial, fire-fighting equipment is one of the oldest and most experienced in Europe. Household submersible pumps of the Wilo brand are manufactured using the latest engineering developments.
Grundfos submersible pumps are durable and high-quality Danish-made devices. The model range of these products is represented by various types of pumps. Grundfos produces both drainage and borehole pumps, as well as sewage pumping stations.
Submersible pumps from the German manufacturer Al-co are able to provide water to your garden plot and country house. The pumping equipment of this machine-building concern has been produced for more than seventy years. With Al-co's wide range of submersible pumps, you can choose the one that best suits your home.
Submersible pumps have been produced by the Russian company "Dzhileks" since 1993. These products from "Dzhileks" will delight you not only with a very high level of quality, but also with their low prices. Constant development in the field of improving pumps allows the Russian company to compete with more experienced Western companies.
