The recommendation of the expert is necessary in any question which demands availability of certain knowledge if it is technical subtleties. The pump is necessary when there is no central water supply. Inhabitants of rural zone or those who build country house, and intend to provide it with all conveniences face this problem.
If during investigation of expected action area the underground drinking water source has been found, sharply there is question of the choice of the pump and to selection to it the corresponding spare parts. Thus the problem is solved even before construction of the house. Optimal variant will be to charge work on investigation, drilling and the choice of all spare parts for uninterrupted water supply in owner-occupied dwelling of one competent organization. As as investigation of water-bearing stratum and the choice of optimum placement of the well, and selection of the necessary mechanisms and filters for pure receiving rather difficult process demanding special knowledge. If it is only required to put column on the seasonal dacha, it is possible to manage and by own efforts, having employed only the machine for drilling of the well and having bought pipes.
It is necessary to approach question responsibly, to need of people who will live in the house, have to be provided completely. Drink, washing and cooking will require very many water. It can be got also from well, but more and more people give preference to the well. At construction of surface facilities for the well the owner by all means will need the pump, and it is desirable not just good, but really suitable to operating conditions and needs. In this case the person ignorant by all means will need professional advice.
Main types of pumps and their compliance to task
There are two main categories of pumps. They differ from each other in depth with which are capable to extort water. On fluke of nature the source of reviver can be located also at depth of 5 meters, and is absolutely deep, on 50-100 meters.
Construction of big private possession is carried out for wealthy people. Therefore future owners with considerable means not especially think of depth of water-bearing stratum, and the forthcoming expenses on water supply. Besides the extensive territory of the site allows to choose the optimum place for location of the well. And here owners of standard country plots are limited not only in the choice of location for placement of the device, but also in the choice of more advanced and expensive models. Though depth of the water carrier will remain the main criterion which will define the unit acquired for water pumping out all the same.
Deep bedding of layer with water demands the powerful and difficult device. Insignificant on depth allows to manage simpler and less strong. But the first that should be considered – whether the equipment will be outside, and then the superficial pump is bought, or it needs to be placed underground, and then it is necessary to buy submersible.
When the superficial pump is bought
Owners of small seasonal dachas or country houses with small dimensions give to the superficial pump preference. They have pleasant feature which does them by practical acquisition. The device of this kind is compact, does not demand any special labor input, except the equipment of dry site to prolong operation term. It can be used for pumping of water from tank, tank or other tank where it is stored by owners who have no centralized water supply. If the well exceeds depth with which the pump can effectively pump water, and the owner has chosen superficial type, he should buy the portable ejector which needs to be lowered down to the well. It will cause not only additional inconveniences, but also the accompanying expenses. Superficial pumps are made 3 types, and each of them has shortcomings and advantages:
- Vortex, working by means of shaft with blades, compact, inexpensive, and owing to this circumstance popular. Possesses two essential shortcomings: low efficiency and ability to pump over only water without impurity. It will be trouble-free if the small daily volume of clean deep-well water is extracted.
- Centrifugal has great technical capabilities if to compare it to vortex. He will cope also with small impurity, and with bubbles, and air locks arising when pumping. This necessary bonus was appreciated by private house owners who pay for centrifugal pumps, despite higher cost.
- Ejector can work with the well depth even in 30 meters, however they have low efficiency, and in the well it is necessary to lay two pipes at once, and it limits possible scope of the pump and increases costs of the well device.
At each of them the features which can act as advantage or shortcoming. It is impossible to tell unambiguously, the best, what of types of superficial pumps. They are made for the solution of different tasks with water supply, and when choosing specific model it is necessary to consider all nuances.
Main subtleties of the choice of the superficial pump
It is better to choose the suitable unit by means of the consultant or the specialist in installation, without looking back at what model is on sale better or is in great demand. Each buyer has different level of requirements, certain conditions and financial opportunities can significantly differ.
When choosing the superficial pump it is necessary to be guided by the following factors:
- daily need for water (to the maximum);
- calculation of water costs of long-term perspective, considering that requirements grow in certain season (watering of kitchen garden, filling of the pool, the temporary increase in quantity living in the house);
- assessment of real opportunities of the well during the summer period, considering reduction of stream during the summer period while waters it is required more normal;
- expenses which should be made on installation and protection of the pump against environment and also possible expenditure for running repair. To more rare models it is much more difficult to find spare parts for repair and also additional consumables;
- arrangement of rather reliable caisson with necessary isolation;
- ways of ensuring constant availability of water in pump, and opportunity without excess power expenses to add water manually if it is required.
To make reliable main caisson and it is correct to equip the well, it is insufficiently simple to look at photo with already working installation. Both the special equipment, and calculations made by the expert and the responsible choice of the pump is required. At the same time it is necessary to remember that expensive and advertized unit can be absolutely unsuitable in specific conditions.
Submersible pumps for the well
In the market there is set of submersible pumps which differ in dimensions, the power and other technical characteristics. The choice of specific model will depend on diameter of the well, its volume and depth and also on that how many water from it is going to be extorted.
If to be guided by depth of water-bearing stratum, submersible pumps are used with depth over 9-10 m. There are three basic principles of their work:
- centrifugal;
- screw;
Indisputable advantage of screw – ability to pump over strongly contaminated water so get them mainly for water-bearing strata without natural filters. Their opportunity to pump over the untreated water is connected with the specific device from the rotor with rounds and the stator with internal thread. Vibration which the cored winding and diaphragm from rubber enter are unpretentious, reliable and cost rather not much. Often they are taken as economic option. Their only shortcoming - unfitness for work with the water polluted by sand. Centrifugal differ in small dimensions and very high efficiency. For the well of considerable depth with small diameter – optimal variant.
How to choose suitable
Behind purchase of the pump it is necessary to go to shop, surely having taken information on the well. This information can be obtained from experts who directly drilled the well. After completion of works technical data sheet of construction where specific characteristics of the made drilling will be in detail specified is issued. Pay attention on:
- static level;
- dynamic level;
- output;
- well bottom basis mark;
- pipe diameter.
If you are not strong in the field, it is necessary to approach with all information the selling assistant in shop of pumps. He will be able to offer optimal variants, based on the accurate dry facts. The owner will be able to choose suitable him at the price, exterior and functionality from the offered models.
