HOW TO CHOOSE A PUMP FOR WATER SUPPLY TO COUNTRY HOUSES OR PRIVATE HOUSES?
Pumping equipment for country houses and cottages is always in demand, for it makes bathing, washing dishes, and other domestic cares much more comfortable. Professionals advise that wondering which product to choose, you should pay attention to the depth of water. If it does not exceed 8 meters, the easiest way is to apply pump equipment of self-priming type.
If the storage container or reservoir for water has already been prepared, the method of selection of such a pump is simple. All that is needed for it to work is setting a sensor in the container. It will monitor the water level for the container not to be overflowed.
Experts note that in order to avoid emergency water excess the container should be equipped with an overflow pipe. All these conditions are met in equipment of as self-priming type from Grundfos and other manufacturers of global renown.
IN WHAT CASES SHOULD YOU CHOOSE A PUMP STATION AND HOW TO MAKE A RIGHT CHOICE?
If you need water supply under a higher pressure than a self-priming pump can provide, or there is not enough space for the piping between the storage container and the bathroom and lavatory equipment, it is recommended to use a self-priming pump integrated with a membrane tank.
A self-priming pump installed on such tank and equipped with a pressure switch is called a pump station. Being integrated with such a station, all water heating devices would definetely work efficiently. In addition, in case there are problems with the electricity, it can provide good opportunities for reserve water supply. The choice of a pump station for a country house can be carried out jointly with the specialist, taking into account all the conditions. Despite the impressive name, the unit is compact - it could be easily carried by one person.
While contamplating which pump station to choose in order to use it outside the house (for example, for pumping water out of a well), you should also pay attention to the depth of water. If the depth of 8 feet is not exceeded, you can use the same device as inside the house.
Only a specialist can give a final piece of advice how to choose a submersible pump for a well, after having found out all the features specific to your case. However, the choice of the submersible well pump must be determined by the fact that the device is securely protected from "dry run" in case water level drops below the level of water intake.
Having chosen where to buy the pump station and which model to prefer, you should consider the conditions of its operation. Therefore, for winter intake the pipes coming from the well to the house, and sometimes the well should be additionaly insulated.
HOW TO CHOOSE A BOREHOLE PUMP?
If water of a good quality is at a depth of over 8 meters, selection of more complex equipment - a submersible borehole pump – is required.
You should confer with a specialist how to select a borehole pump. The choice is to be based on its technical documentation. In this case the borehole diameter is important, for it cannot be much bigger than the pump diameter.
Due to the presence of Grundfos pumping equipment and that of other famous manufacturers on Russian market, the choice of boreholes pumps has become much easier. Experts believe that today every one can find a device that fits exactly to their needs, namely it will pump the optimal number of cubic meters of water per hour.
HOW TO CHOOSE A CIRCULATION PUMP FOR HEATING?
The problem how to choose a circulation pump is as popular as that how to choose a borehole one. Heat engineers claim that the program of pump selection for heating depends on how much heat the building consumes during the coldest season. Typically, the selection of the circulation pump from a reputable manufacturer such as Grundfos, can be carried out according to European standards of heating.
Specific heat consumption is the rate taken into consideration to measuse pump capacity needed. One more feature the choice of the circulation pump for heating should be based on is the ability to create pressure that can overcome the system resistance.
HOW TO CHOOSE A DRAIN PUMP?
The choice of a drain pump is based on its ability to clean the premises and plots from ground water, sludge deposits and mud. Grundfos and other manufacturers of pumping equipment achieve this by equpping pumps with a so-called float.
This float is not only a sensor that adjusts the pump operation, but it also protects the unit from "dry run" in case the precipitate has already exfoliated from the bottom and has been completely pumped out together with contaminated water.
The choice of a centrifugal pump for drainage is not that complicated, for it is enough to confer with a specialist, who will tell you about its features in layman terms. |
