To extort water from the swimming pool or well – no laughing matter. Here in couple of buckets not to manage in any way. For pumping out of considerable volumes of water there are special pumps which separate models differ in usability, compactness and reliability.
Instruction
1. To pump over clean or a little contaminated water, you need the drainage submersible pump. Such pump is supplied with the switch of float-operated type which is capable to switch-off automatically the device at decrease in height of water below admissible. And at achievement of the set level automatic equipment itself turns on the pump.
2. The submersible pump is very convenient for pumping out of water from swimming constructions, cleaning of water of wells, cellars, at water intake from artificial tanks or the rivers. It is compact and simple in service.
3. Such pump can be quite used in the systems of watering and also to groundwater recession. Safe amount of mechanical impurity in the pumped-over water, sometimes up to 5% of water volume. Usually there are restrictions for the linear sizes of foreign particles – no more than 5 mm. Consider only that I will suck small stones and metal objects too hard.
4. Of course, such pump has quite certain scope of application and cannot be used in production of construction jobs and also at pumping out of sewage. One of advantages of the drainage submersible pump – protection against work without water that helps to prevent its misuse and failure.
5. Most often the body of pumps is produced from plastic or stainless steel. Models from gray cast iron meet. Such execution allows to provide to the submersible pump high reliability and durability even in difficult operating conditions.
6. Choosing under the needs specific model of the pump for water pumping, pay attention to alphabetic references. If letters are absent, then the unit is made of plastic and intended for pumping of clean or slightly contaminated water. Letter "H" designates the pump from "stainless steel", "Ф" - the pump for pumping of strongly polluted waters.
