In country houses and cottages, modern people strive to provide comfort close to that which creates accommodation in an apartment where there is a constant centralized water supply, sewage and other amenities. To make such conditions without using pumps to pump water from the pit is almost impossible. The scope of such devices is quite wide. These are private land plots, industrial construction, agricultural land and others. Thanks to such devices, it is possible to ensure uninterrupted water supply to houses, as well as to use them for watering gardens or drain wells and trenches.
Pumps for pumping water from the pit are of several types. As a rule, these are surface and submersible models. They, in turn, are divided into subspecies. In the article, we consider in more detail each of them.
Surface water pumps
Such pumps do not require submersion in water. They are located, as the name implies, on the surface, and only the hose is immersed in the liquid. Such structures are not able to pump water from a great depth. However, their indisputable advantage is the ease of operation and maintenance. A surface pump for pumping water from a pit is often purchased for irrigation of a land plot, shallow trenches, or for draining basements.
Pumping stations
More technological designs are pumping stations, which, in addition to the pump, have a control unit and a pressure storage. The accumulator installed in the station allows you to make a supply of water. It turns on only when the liquid level drops to a certain mark.
Currently, such a pump for pumping water from the pit (device performance varies from 10 to 2400 l / min) is produced by many companies. For example, Jumbo pumping stations have a built-in ejector. They provide a head up to 50 m, are equipped with a self-priming function from a depth of 8 m. Such devices are quite effective at a low cost. Also, many protective devices are included in their package, which is an indisputable advantage.
Submersible pumps
Such equipment functions directly immersed in a liquid and has the ability to lift it from a very great depth. In this case, well and well pumps are allocated for pumping water from the pit. The latter have proven themselves in working with constantly fluctuating fluid levels. Stability of productivity is provided by the lower pumping method. The pumps can operate in partial immersion mode. Most often, consumers prefer to purchase products with a float protection system, triggered by a critical decrease in water level.
Well pumps are used everywhere for irrigation and permanent water supply of country houses. Many people choose such devices, due to their compact size and narrow shape, which allows to extract water from even the narrowest wells and pits. Products are characterized by a high level of pressure and high performance.
Drainage and circulation pumps
A drainage pump for water is used in sewage treatment plants and drainage systems. It works even with liquids containing various impurities. Its purpose is suitable for many fields, for example, such a device can be used for pumping water during flooding, from cesspools, wells, pools, etc. Products are characterized by mobility, long service life, and reliability.
The circulation pump is necessary for autonomous water supply systems in order to ensure forced circulation of the coolant. It is structurally similar to drainage.
Pump Overview
Among the huge assortment of products under consideration, it is recommended to pay attention to borehole pumps for pumping water from the Vodomet pit. They are made of durable wear-resistant materials and adapted for use in Russian conditions.
Grundfos well pumps also have a long service life and a high level of wear resistance, have good motor protection from overheating, overloads, power surges.
The DAB drainage pump is equipped with a monoblock design with a reliable electric motor. The fluid pressure in the system is low. These units can work in automatic mode. At the same time, when choosing DAB drainage pumps, it is important to remember that they can work with dirty water, but there should not be any chemically aggressive substances in it.
Pumps for pumping water from the pit "Gnome"
This design deserves special attention, since this type of equipment has a wide purpose. The model range is represented by different devices that are designed for irrigation, drainage pits or trenches. It is also worth paying attention to the fact that Gnom pumps can be used in the construction of industrial and residential buildings, in the operation of subways, in mines and other large-scale places.
When familiarizing yourself with this product, you should pay attention to the labeling. For instance:
- T means the ability of the pump to operate at high temperatures (up to 60 °).
- Ex - the device is designed for pumping water with impurities of oil (up to 10%).
