To comfortably live in a country house, you need to arrange a water supply system. If your site has its own source of water intake - a well or well, then the most reasonable solution will be the purchase of a pumping station. Stick when choosing such an apparatus of our recommendations.

When buying a pumping station, take into account the possibilities of your well:
The performance of the apparatus should be a little less debit of water intake. Remember that constant pressure will not be provided in the pipes if the productivity of the well is less than 1.7 cubic meters per hour.
The depth of water absorption is also very important when choosing a pumping station. Only the distance is only the distance between the pump axis and the water mirror. Distance under water can not be considered. Self-priming stations raise water from a depth, which is less than 9 m. Vortex models are used for wells up to 7 m. Multistage devices, depending on the model, suitable for a well depth 7-9 m.

When choosing a pumping station, take into account productivity - water consumption. It is usually calculated per unit of time - a minute, hour, day. The higher the performance, the device will work faster. For a comfortable stay on one tenant per day, up to 1000 liters of water (taking into account the adoption of the bath twice a day). To find out the final consumption of water, just multiply this indicator on the number of tenants in the house. At the same time, take into account the maximum flow rate. This will help to ensure the possibility of simultaneously using multiple water consumption points. Based on the following data, it is easy to calculate the daily water consumption and consumption per hour. Remember that water consumption when using a bath or shower - 8-10, a crane in the kitchen - 6, toilet - 6 l / min. If you plan a pumping station to apply for your farm, for example, watering the garden, add another 2 thousand l per day.

When buying a pumping station you need to know the water pressure. To determine it, add 6 meters to the height of your home and multiply the result to the pressure loss indicator - 1.15. If the height of your house is 10 m, then the minimum pumping station pressure when using the well should be 18.4 m. If you plan to raise water from the well, add another number to this pressure characteristic - the depth of the well. If the water supply is located far from the house, then you should consider that 1 meter of pressure will be lost on every 10 meters of the length of the pipeline. In reality, it is usually enough for a pressure of 800-1000 l / h.

Pay attention to the hydroaccumulator. When choosing a volume of expansion tank for a pumping station, consider the amount of water to be consumed. With significant consumption you need a large volume tank. Models with parameters 24-50 liters are the most popular. If 1-2 people live at the cottage, the volume can be minimal - 24 liters. It also concerns situations where all the points of water resistance are in the kitchen and in the bathroom. For 3-4 people you will need a hydroaccumulator, a volume of 50 liters.

Many characteristics of the pumping station depend on the material from which the housing is made, namely durability, cost, noise level:
Steel devices look beautiful and have a high price. They are able to maintain the properties of water without change. However, there is significant noise when working.
Cast iron stations are most durable. The level of their noise is much lower. The only minus the use of such an aggregate is the possibility of rust formation. If you choose this model, then firm about the presence of a protective layer.
Plastic models. These are the cheapest pumping stations. In addition, the noise level is low, and the rust in water is missing. However, their service life is much lower than that of the hulls made of metal.

Pumping stations in our market are predominantly predominantly by two manufacturers: Grundfos (Germany) and Speroni or Marina (Italy). Pumping stations under the Grundfos brand are also assembled at the plant in Istra. Instead of individual components, with their manufacture, whole fees are used, which makes such pumping stations are very high-quality, but at the same time very expensive. Also, Grundfos models are French assembly. Speroni pumping stations are not only Italian assembly, but also Chinese. To distinguish the latter, in the title, look for a special label - Hobby Line or HL.
And finally, find out what the ejector should be in the pumping station. If the depth of which water is raised is 7-8 m, select a model with a built-in ejector. For wells, the water is below 9 meters and up to 45 meters, suitable pumping stations with a remote ejector.
