Centralized water supply in country houses and summer cottages does not always work as desired: interruptions, disconnection, weak pressure. Therefore, many homeowners prefer to install on their site autonomous swing station. In order to have no problems with water supply in the future, you will have to think in advance how to choose water pumps and how to install them.
There are many models on the market that are divided into two main groups: professional and domestic. The former are capable of transmitting up to 3–4 tons of water per minute, while the performance of the latter is about 60 l / min. For a small private house a household pump is more suitable, but which one?
According to the principle they are:
According to the installation site and the method of water intake, the pumps are separated:
For the purpose of use, the units are:
The choice of a particular pump determines its purpose and source of water. To pump out a liquid from a nearby reservoir, natural or artificial, and direct it to watering a vegetable garden, a submersible drainage pump is needed. They also drain the flooded basements or trenches.
To deliver drinking water to the house, you will need a downhole installation with a filter or a submersible well. If the source is relatively clean, then you can download and surface apparatus. It does not need to be lowered into the pond and make sure that it is always drowned - the pump takes water with a hose.
A powerful circulation pump will operate in the plumbing and heating system.
The most important characteristic of a pump will be its capacity, that is, its ability to pump a certain amount of water per unit of time. A family of 4-5 people for living is sufficient apparatus with a capacity of 30-40 liters per minute.
The next significant indicator that needs attention is the pressure or height to which the installation can raise water. The average figures for domestic pumps are as follows: the intake depth is 4-7 m, the water column is 10-15 m. These parameters are important, because sometimes you have to not only pump the liquid from the depth, but also deliver it to the second or even third floor while maintaining pressure. Moreover, the external pumps for wells are vortex and centrifugal. The former are more suitable for shallow wells and create good pressure in the pipeline. In addition, their price level is somewhat lower. Centrifugal machines are designed for very deep mines.
The pressure in the plumbing system depends on these two characteristics. The pressure generated varies for different pump models. And the value you need is calculated depending on the size of the site, the way groundwater is deposited and your needs.
Different device brands
When buying a particular brand of pump you should consider:
When choosing a submersible pump, it is important that it corresponds to the cross section of the well. Its maximum overall dimension must be at least 10 mm smaller.
Some parts of the water pump are considered consumable components, such as replacement filters and hoses. Sometimes it is necessary to replace switches or control units. Accumulators can also fail and have to be changed sooner or later.
Pay attention to the possibility of servicing your installation and the proximity of repair centers. Warranty obligations of different manufacturers sometimes vary widely.
