Every person who has his own plot has repeatedly encountered such a problem as lack of water. Shutting off the water can be only a few hours, and sometimes water may be absent for several days, in such cases, many drill a well and install water pumps. Or, you may be faced with the problem of water shortages during the irrigation season, as a rule, the water pressure at such hours is very small and, again, without a pump.

So, buying a pump, you at times make your work easier. You will always have water, for domestic needs, for drinking, as well as for watering your garden and vegetable garden. Moreover, in today's market there is such a large range of products, both domestic and foreign production. Pumps are of different types and designed for different purposes therefore, it will not be difficult to choose it.

Consider what types of water pumps are. They are divided into two broad categories: this household pumps designed to be installed on their own site and professional - large pumps that are installed in various industries.

In this article we will look at household pumps in more detail, since we are still going to talk about them. But it is worth mentioning the main differencee household pumps from industrial: they have a longer lifespan and with the help of such pumps, it is possible to pump large quantity cubic meters of water. Such pumps are used to ensure large settlements water or any industrial enterprise.

Types of household pumps

By purpose pumps are divided into:

• devices for water supply;
• drainage pumps;
• circulation pumps.

By working principle pumps are divided into:

• well;
• borehole;
• self-priming;
• hand held.

By fence method water pumps are:

• outdoor;
• submersible;
• injector.

Рассмотрим более подробно насосы по fence method воды.

Outdoor pumps

Outdoor pumps используются for water intake из колодцев, открытых водоемов, систем водоснабжения. При работе насоса, water is sucked into the pipe, one end of which is in the water. The depth with which he is able to suck water his power. In turn, the external pumps are also divided into two types: vortex and centrifugal. The former are used to extract water from shallow wells, while the latter can cope with pumping water from deeper wells.

Virtues external pumps:

• easily pumps water to a height of 15 to 20 meters;
• the pump is easy to maintain;
• just mounted.

disadvantages external pumps:

• with its help it is impossible to pump out water from a depth of more than 7−8 meters;
• The electric motor is very noisy, there is, of course, the option to purchase a silent pump, but its price will be several times higher.

Byгружные насосы

Byгружные насосы, также как и наружные, используются for water intake from wells and boreholes. By the very name you can understand that such a pump is immersed directly into the water itself, so that he does not need to provide protection for dry running.

Virtues submersible pumps:

• with extraordinary ease, such a pump is able to lift water from great depthcope even with a depth of 40-50 meters;
• silent operation of the pump motor;
• does not take up much space;

One of the biggest disadvantages of submersible pumps is its high price compared to outdoor.

Injection Pumps

Injection Pumps применяются в том случае, если есть необходимость pump out water from the depths more than 10 meters. The injection pump differs in that it has two suction pipes: one with a larger diameter and the other with a smaller one. At the ends of both pipes there is a special nozzle - injector. Thanks to this nozzle the pump can pump out water from a greater depth.

Advantages of injection pumps:

• affordable, reliable and easy to install;
• safe;
• provide the rise of water from a great depth;
• suitable for domestic use;
• have great performance;
• power consumption is reduced.

Water pump design

If we consider the water pump from the engineering point of view, it seems to be a hydraulic machine that is designed to pumping water in horizontal or vertical direction. In order for the water to start moving in one direction or another, it must be communicated to a certain kinetic energy. On this basis, a water pump can be thought of as a device that converts electrical energy into kinetic energy, through which fluid moves.

By the principle of operation, the pumps are divided into centrifugal and vibration.

For example, a centrifugal pump consists of such elements as:

• working chamber;
• Working wheel;
• guide vane;
• pump shaft;
• discharge pipe;
• pump casing;
• suction nozzle.

But vibration pumps have in their design flexible membrane which shares the working capacity. On one side of the membrane is a mechanism that sets it in motion, and on the other - area with water.

Popular water pump manufacturers

One of the popular manufacturers of water pumps is the Italian company Calpeda. She is considered recognized leader in the world market of pumping equipment. The pumps produced by this company are considered the most reliable in the world. They are made with the help of high-precision equipment, highly skilled personnel work in the production and, moreover, the company is famous good technical traditions. Absolutely all materials and spare parts for Calpeda pumps are made in Italy.

In addition to this recognizable brand, there are also such as Gardena or Makita, which are also pretty recognizable brands. Are stable and reliable companies that are currently only increasing their potential.

The cost of water pumps to compare them

Prices for water pumps can be completely different, depends on the price of:

• engine power;
• type of pump;
• brand manufacturer.

Therefore, before buying one or another pump, it is worth first to decide what type of pump you need, you also need know its power, and then consider the pumps of different manufacturers.

For example, a 900 W submersible type Gardena water pump with a maximum capacity of 5500 l / h would cost in the range 8 thousand rubles. A pump of the same brand with only a power of 500 W will cost already within 4 thousand rubles.

If we consider the surface type pumps, they are more powerful, respectively their price is higher. For example, the pump of the same brand of surface type of power consumption of 1000 W is in the area 15 000 - 17 000 rubles. At the same time, the price may be inflated if the pump has any features, for example, automatic control of the water level.

Surface type pump Makita power 710 - 750 W costs almost as much as Gardena, while having less power but has low noise.

Based on the foregoing, when buying a pump, first of all it costs decide on its type. It is necessary to know where you will be pumping water from, after which you have to make a choice regarding one or another type of pump. Also worth knowing about water volume will pump out the pump. And then choose the brand of the manufacturer and compare prices for them.
