Pumps for pumping water from a pit: description and technical characteristics

In out-of-town houses and cottages, modern people strive to provide comfort, close to the one that creates accommodation in an apartment where there is a permanent centralized water supply, sewerage and other amenities. It is practically impossible to make such conditions without using pumps for pumping water out of the excavation. The scope of such devices is quite wide. This is private land, industrial construction, agricultural land and others. Thanks to such devices, it is possible to ensure uninterrupted supply of water to homes, as well as to use them for watering vegetable gardens or to drain wells and trenches.

Pumps for pumping water from the pit can be of several types. As a rule, these are surface and submersible models. They, in turn, are divided into subspecies. In the article, we will examine each of them in more detail.

Surface Water Pumps

Such pumps do not need to be lowered into 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 undeniable 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.

Pump stations

More technological designs are pumping stations that have, in addition to the pump, a control unit and a pressure accumulator. The hydroaccumulator installed in the station allows you to make a water supply. It turns on only when the liquid level drops to a certain mark.

Currently, such a pump for pumping water from the excavation (the productivity of the devices varies from 10 to 2400 l / min) are produced by many companies. For example, pumping stations "Jambo" have a built-in ejector. They provide a head up to 50 m, equipped with self-suction function from a depth of up to 8 m. Such devices are quite effective at low cost. Also in their complete set includes a lot of protective devices, which is an indisputable advantage.

Submersible pumps

Such equipment functions directly immersed in the liquid and has the ability to lift it from a very large depth. In this case, wells and well pumps are extracted to pump water out of the pit. The latter have proven themselves in the work with a constantly fluctuating liquid level. Stability of performance is provided by the lower pumping method. Pumps can operate in the mode of incomplete immersion. Most often, consumers prefer to purchase products with a float protection system, triggered by a critical reduction in water levels.

Well pumps are used everywhere for irrigation of land and constant water supply of country houses. Many people choose such devices, due to their compact size and narrow shape, which allows them to extract water even from the narrowest boreholes and pits. Products are characterized by a high level of pressure and high productivity.

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 spheres, for example, such a device can be used for pumping water in underflooding, from cesspools, wells, swimming pools, etc. Products differ mobility, long life, reliability.

A circulating pump is required for autonomous water supply systems in order to ensure forced circulation of the coolant. It is structurally similar to drainage.

Overview of pumps

Among a huge range of products under consideration, it is recommended to pay attention to downhole pumps for pumping water out of the pit "Vodomet". They are made of durable, wear-resistant materials and adapted to use in Russian conditions.

Grundfos well pumps also have a long service life and a high level of durability, they have good motor protection against overheating, overloads, and power surges.

The DAB drain pump is equipped with a monoblock design with a reliable electric motor. The liquid head in the system is low. These units can operate in automatic mode. Thus, when choosing drainage pumps DAB, it is important to remember that they can work with dirty water, but there should not be chemically aggressive substances in it.

Pumps for pumping water from the ditch "Gnome"

This design deserves special attention, since the equipment of this type has a broad purpose. The model range is represented by different devices, which are designed for irrigation, drainage of trenches or trenches. It is also worth noting that pumps "Gnome" can be used in the construction of industrial and residential buildings, in the operation of subways, in mines and other large-scale locations.

When reading this product, you should pay attention to the labeling. For example:

• T means the ability of the pump to operate at high temperatures (up to 60 °).
• Ex - the device is designed for pumping water with oil impurities (up to 10%).
