Many owners of private houses and country sites in the absence of centralized water supply quite often apply various pumping equipment. For example, borehole pumps for raising water from well and vacuum pumps for pumping it.
It is the vacuum pumps that have recently become actively gaining popularity among domestic consumers.

Scope of application of household vacuum pumps
Water vacuum pumps or so-called vacuum pumps represent special pumping equipment, the main function of which is to absorb water, gas or gas with a liquid from hermetic cavities. Such pumps are used primarily for:
- pumping water from basements, cellars, pools,
- for watering gardens and other tasks.
Their popularity is explained by simplicity in maintenance and stability. In addition, this type of pumping equipment has the possibility of long-term autonomous work without electricity consumption, which is especially relevant in living conditions. Vacuum pumps have other equally important advantages.
Advantages of household vacuum pumps
Specialists who understand the issues related to the operation of pump equipment, as a rule, allocate the following advantages of vacuum pumps for pumping water:
- high speed;
- the greatest pressure of the launch of such equipment;
- low indicators of vibration and noise when working;
- high strength and reliability of pump design;
- high performance and many others.
Principle of operation of the vacuum pump
The principle of operation of a household vacuum pump for pumping water, as well as any other similar unit, is based on the process of displacement. In the process of its operation, water pumping occurs as a result of changing the dimensional parameters of the working chamber. The magnitude of the vacuum is directly related to the level of tightness of the working space, which can be adjusted and thereby reduce or increase the pressure in a certain place to a strictly defined value during pumping or water intake.
Any vacuum pump has a cylindrical shape. Inside there is an embedded impeller or shaft with an impeller, which has special blades. Impeller is the main element of this device.
The wheel rotates in the housing, partially filled with the working fluid, most often with water. As a result of such rotational actions, impeller blades capture water, which is broken down to the walls. Thus, in accordance with the laws of physics, a centrifugal force arises, which contributes to the appearance of a liquid ring. Inside it is formed free space, which is a vacuum. In turn, gas is constantly moving between impeller blades and the ring.
When the volume of gaps in the field of blades increase, gas absorption occurs through a special slot. The second phase of the vacuum pump is a decrease in the gaps, as a result of which the gas is compressed and pushed out through the slot.
Features of the choice of a household vacuum pump and their varieties
To correctly pick up a high-quality household vacuum water pump, first of all, to pay attention to the quality of the factory assembly of this equipment, as well as on its functional features, the manufacturer's reputation and inquire the reviews of buyers about the work of such a pump.
The quality product should be distinguished by reliability in operation, simple and durable design, which could provide maximum productivity of the unit. Vacuum pumps in their work are completely safe for the environment, do not distinguish harmful gases, are capable of pumping any types of gases and liquids. Many models are equipped with a built-in dirt separator.

Types of vacuum water pumps
Household vacuum pumps are customary to classify depending on the method of creating a vacuum in it:
- The vortex pump is a device, a vacuum in which is created due to the rotational motions of the flat disk with blades. It has a high suction ability, but, at the same time, very sensitive to suspended particles, therefore is not suitable for pumping polluted water.
- The vibration pump is the pumping equipment, the main element of which is an electromagnet, which contributes to the oscillatory movements of the integrated anchor in it and the piston associated with it. Thanks to such oscillations of excess water, it is pushed out. The main advantage of the vibration pump can be considered the absence in its design of the electric motor and any rotating elements.
- The centrifugal pump is a pump whose work is based on the creation of a centrifugal force under the influence of the blades of the impeller. Thus, the necessary water pressure is created.
- Manual water pump is the easiest and cheapest option. Such pumps are piston or imperted. It requires only human physical efforts.
Basic manufacturers of vacuum pumps
The most popular in our country manufacturers of household vacuum pumps are:
Grundfos.
The Danish-German company Grundfos has a tremendous experience of producing such equipment and is one of the world leaders in this area. Grundfos pumps represent highly efficient and reliable water pumping devices. They are distinguished by the modern design and use of modern technologies.
Calpeda.
Calpeda Italian pumps are no longer inferior in quality to their famous competitors. They stand out reliability and durability in the work. This company has become the first to begin to use polymer components for their pumps, thereby facilitating their design. Today Calpeda pumping equipment is an excellent value for money.
Wilo.
The German company WILO is one of the leading European manufacturers of high-quality pumping equipment, which is characterized by reliability and ease of work. Wide model range of Wilo pumps, multifunctionality, high-quality components and greater efficiency in work is all that distinguishes this products from competitors.
