Pump for pumping water from the basement: overview, characteristics, choice

One of the important devices for giving ispump for pumping water from the basement. After all, it often creates a huge number of problems that can adversely affect the building above it. All this with bad care can cause huge damage to your property. It is worth saying that this problem can extend not only to private sectors with cellars, but also multi-family city houses.

Why does water cause trouble?

Most often in the basement of the problem arise due to such reasons as:

• thawed liquid;
• lack of depth of water;
• precipitation;
• there is no drainage system;
• the building is located on a slope.

Therefore, a pump is required to pump water from the basement in the presence of the listed factors. In addition, the liquid can be removed by other improvised means.

How to pump out water?

Method using the toolboxvery complex, lengthy and time consuming. That's why it's better to use a pump to pump out dirty water, so you'll do everything much quicker and without extra effort. It is very important to choose the right device. Types of pumps are different. For example, drainage structures are appropriate if the pumped water has a minimum of impurities. But pumps of fecal type can be used to get rid of liquid of different degree of pollution.

Types of fecal equipment

The pump for pumping water from the basement of this type also has its own modifications. There are four basic groups:

• The most budgetary faecal pumps are used for cold drains. There is no grinding device in them. It is best to use for storm sewage or drainage.
• Installations for cleaning sewers with a high drainage temperature without a chopper. They are used for bath and shower rooms, as well as for waste from the work of washing machines and dishwashers.
• Pumps with a chopper for cold drain. They are used in most sewers with a temperature of up to 40 degrees.
• The most expensive are devices with a chopperfor hot drains. Used for bathing complexes, public premises with high humidity. For private households are almost not used because of their high cost.

Classification by type of installation

Each pump for pumping water from the basement differs from the other in the manner of installation, not only for its intended purpose.

For example, surface-type installations canto be applied in pumping sewerage stations or cesspools. They are mounted on the surface, and a suction pipeline is placed in the sinks, with a depth of 4 meters maximum.

A submersible pump for pumping water has goodpressure properties, some models can pump drains with a depth of up to 100 meters. In terms of layout, they are divided into vertical and horizontal, set them on the bottom of the sediment bowls, using the guides. To date, these are the most demanded designs on the market.

Also recently, more and more popularityacquires a semisubmersible model. It is placed at the top of the drain using float systems. The device of the pump of this type does not assume the presence of a chopper, therefore the scope of its application is limited. Most often they are used in accumulators of precipitation or groundwater.

Differences of the fecal pump from the drainage

The fecal (sewer) type is always equipped with a chopper, capable of grinding the contaminants and converting them into a homogeneous mass.

A drainage pump for pumping water, which, likewas said above, it is submersible and superficial, it is necessary to choose according to the depth. Submersible structures are very easy to install, the main thing is to properly ground them and pick up a hose that would match them in length and diameter.

Features of self-priming structures

To equip a good water supply systemautonomous type in the country or suburban area, it is best to choose products of a special type. Such a self-priming pump can lift water from a depth at a short distance from the fence, passing through itself.

There are many models on the market andmodifications of products of this type, while for domestic use with them must be familiarized. After all, some types of pumps can be approached in this or that case, but not in the other.

Quite often they include a membrane or storage tank. Such equipment is considered a full pumping station.

Classification

Self-priming pump can be equipped withbuilt-in or remote ejector. In a similar construction, the liquid rises when it is discharged. Ejector pumps are very noisy, so they are recommended to be located away from living quarters. At the same time, their key advantage is that they can lift water from the depths of about 10 meters. The feed pipe is lowered into the source of the fence, and the pump is also placed nearby. This layout of the installation will make it easy to control its operation.

The second type of self-priming pumps is withoutejector. The fluid here rises through the use of a hydraulic device with several stages. Noise such designs do not publish, but are inferior to the first kind in terms of the depth of the fence.

When using a self-priming unit, it is very important to install a protection against dry running, otherwise it may break.

Differences of centrifugal structures from vortex

Pump for pumping water from the basement of the centrifugaltype is equipped with a spiral casing. It rigidly fixed the wheel on the basis of discs with blades. They are bent to the sides, opposite to the direction of the main movement. The pump with the pipeline is connected by means of a branch pipe with the required diameter.

Centrifugal plants can have several impellers, but this does not affect the principle of operation. The fluid in any case will move under the action of the force that appears as a result of rotation.

Vortex pumps are designed for pumping both the water itself and mixtures based on liquids and air.

Oxygen is absorbed into the body by vacuum, andthen everything is mixed. When both components of the mixture enter the working chamber, they separate from each other due to their differences in terms of densities. The air leaves the supply line and the water is recirculated. The oxygen is then removed through the suction line and the body is filled with liquid. After that, the pump starts its work.

How to choose the installation?

For a product such as a pump for pumping water,price is not the most important factor for choice (cost can be from 2 thousand rubles for the simplest models and above). Be sure to specify in what conditions it can be used before purchase. In particular, find out the depth of the clarifier, then decide on the pressure. The productivity will depend on the volume of the drains, this too should be paid attention.

When buying the most common type of submersible pump for your holiday needs, consider the following:

• The body of the product should be made of cast iron, steel or plastic, also it is good when it contains sealing seals resistant to chemical influences.
• If you want to purchase a pump with a chopper,then its quality should be paid special attention. Be sure to see what the impeller looks like, which is used as a cutting element. Many experts recommend choosing those models where a special knife is installed on it. Thanks to this, the best performance is ensured, and you can pump more storm and sewage drains. If there is no such knife on the pump, but there is just a sharpened edge, its price will be lower, but some components will become more difficult to grind.
• Pay attention to the power of the unit. It is better to choose those models that have a margin of at least 30 percent for this parameter. Thanks to this, the pump will be able to work in almost any situation in normal mode and not be overloaded. In addition, it will significantly increase its service life.
• If you want the installation to workautomatically, you need to choose models equipped with built-in control systems. Their peculiarity lies in the fact that they start to function on their own, when the level of runoff in your settler reaches a certain index. All of this very simply works and does not need expensive repairs or maintenance. But experts still recommend not to save when buying models of this type and give preference to the products of famous brands, rather than questionable cheap devices of unknown origin.

It is also necessary not to forget that independentlyfrom the chosen model and its modification and type, the efficiency of the pump depends not only on all of the above, but also on its installation. On it, too, you can not save, do it yourself better when you have experience in this matter. In other cases, it is better to entrust this kind of activity to specialized specialists.

To save on installation of the pump for pumping out drainsnot worth it. Thanks to this decision, you will save yourself from the need to call the sewerage equipment. And even the most expensive installation can pay off in just a couple of seasons.
