One of the important devices for giving is a pump for pumping water from the basement. After all, it often creates a huge number of problems that can negatively affect the structure located above it. All this, if not properly cared for, can cause enormous damage to your property. It is worth saying that a similar problem can extend not only to private sectors with basements, but also to multi-apartment city buildings.
Why does water create trouble?
Most often, problems in basements arise due to reasons such as:
- melt liquid;
- lack of accounting for the depth of water;
- rainfall;
- no drainage system;
- the building is placed on a slope.
Therefore, you will need a pump to pump water from the basement in the presence of these factors. In addition to it, the liquid can be removed by other improvised means.
How to pump water?
The method using improvised devices is very complex, lengthy and laborious. That is why it is better to use a pump for pumping out dirty water, so you will do everything much faster and without any extra effort. At the same time, it is very importantchoose the right device. There are different types of pumps. For example, drainage structures are appropriate if the pumped water has a minimum of impurities. But fecal-type pumps can be used to get rid of liquids of varying degrees 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 main groups:
- The most budgetary fecal pumps that are used for cold drains. They do not have a grinder. Best used for storm water or drainage.
- Installations for sewerage treatment with high temperature wastewater without chopper. They are used for bath and shower rooms, as well as for waste from washing machines and dishwashers.
- Pumps with chopper for cold runoff. They are used in most sewers, taking into account temperatures up to 40 degrees.
- The most expensive are devices with a grinder for hot drains. Used for bath complexes, public places with high humidity. For private households, they are practically not used due to their high cost.
Classification by installation type
Each pump for pumping water from the basement differs from the other in the way of installation, not only in purpose.
For example, surface-type installations can be used in pumping sewer stations or cesspools. Themmounted on the surface, and a suction pipe is placed in the drains, while the lifting depth is 4 meters maximum.
And the submersible pump for pumping water has good pressure 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, they are installed at the bottom of the sedimentation tanks using guides. To date, it is these designs that are most in demand on the market.
Also, the semi-submersible model has become more and more popular lately. It is placed at the top of the drain using float systems. The device of this type of pump does not imply the presence of a grinder, so its scope is limited. Most often they are used in storage of sediments or groundwater.
Differences between a fecal pump and a drainage pump
The fecal (sewer) type design is always equipped with a grinder capable of grinding impurities and turning them into a homogeneous mass.
And drainage pumps for pumping water, which, as mentioned above, are submersible and surface, must be selected depending on the depth. Submersible structures are very easy to install, the main thing is to properly ground them and choose a hose that matches them in length and diameter.
Features of self-priming designs
To equip a good autonomous water supply system in a country house or a suburban area, it is best to choose products of a special type. Such a self-priming pump can, at a short distance from the place of intake, raise water from the depths, passing through itself.
There are many models and modifications of products of this type on the market, and for domestic use, you should definitely familiarize yourself with them. After all, some types of pumps may be suitable in one case or another, but not in another.
Quite often they include a membrane or storage tank. Such equipment is considered a full-fledged pumping station.
Classification
Self-priming pump can be equipped with a built-in or remote ejector. In a similar design, the liquid rises when discharged. Ejector pumps are very noisy, so it is recommended to place them away from living quarters. At the same time, their key advantage is that they can raise water from depths of about 10 meters. A supply pipe is lowered into the source of the fence, and the pump itself is placed nearby. Such a layout of the installation will make it easy to control its operation.
The second type of self-priming pumps is without an ejector. The liquid is lifted here by using a hydraulic device with several stages. Such structures do not emit noise, but are inferior to the first type in terms of the depth of the fence.
When using a self-priming unit, it is very important to install a dry run protection, otherwise it may break.
Differences between centrifugal and vortex structures
Pumpfor pumping water from the basement of a centrifugal type, it is equipped with a spiral casing. A wheel based on disks with blades is rigidly fixed on it. They are bent to the side opposite to the direction of the main movement. The pump is connected to the pipeline through a pipe with the desired diameter.
Centrifugal plants may have several impellers, but this does not affect the principle of operation. In any case, the fluid will move under the action of the force that appears as a result of rotation.
Vortex pumps are designed for pumping both water itself and mixtures based on liquids and air.
Oxygen is sucked into the case due to vacuum, and then 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 density. The air exits the supply line, and the water is recirculated. The oxygen is then removed through the suction line and the housing is filled with liquid. After that, the pump starts to do its job.
How to choose an installation?
For a product such as a pump for pumping water, the price is not the most important factor for choice (the cost can be from 2 thousand rubles for the simplest models and above). Be sure to check in what conditions it can be used before buying. In particular, to find out the depth of the sump, in order to then determine the pressure. The performance will depend on the volume of stocks, you should also pay attention to this.
When buying a pump, the most common for countrysubmersible needs please note the following:
- The body of the product should be cast iron, steel or plastic, it is also good when it contains chemical resistant seals.
- If you want to purchase a pump with a grinder, then you should pay special attention to its quality. Be sure to look at how the impeller of the design looks like, which is used as a cutting element. Many experts recommend choosing those models where a special knife is installed on it. This ensures better work performance and you can pump more stormwater and faecal wastewater. If there is no such knife on the pump, but 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 installation. It is better to choose those models that, according to this parameter, have a margin of at least 30 percent. Thanks to this, the pump will be able to operate normally in almost any situation and not be overloaded. In addition, it will greatly increase its service life.
- If you want the unit to work automatically, you need to choose models equipped with built-in control systems. Their peculiarity lies in the fact that they begin to function independently when the level of effluents in your sump reaches one or another indicator. All this is very simple to operate and does not require expensive repairs or maintenance. But experts still recommend not saving when buying models of this type and giving preference to products of well-known brands,and not dubious cheap devices of unknown origin.
Also, one must not forget that regardless of 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. You can’t save on it either, it’s better to do it yourself when you have experience in this matter. In other cases, it is better to entrust this type of activity to specialized specialists.
It's not worth saving on installing a wastewater pump. Thanks to this solution, you will save yourself from the need to call the sewage equipment. And even the most expensive installation can pay off in just a couple of seasons.
