As the optional support expands, modern pumps are becoming more functional. The presence of automation and the ability to connect several pumping systems into one complex significantly increases operational advantages. A wave of technological development and traditional water intake units swept through, resulting in a drainage pump with a float switch and electronic control. The introduction of new systems allowed the owners of such devices to carry out economic tasks with great comfort. This may be pumping water from the basement, emptying the tanks, watering operations, etc.
Pump device
Most models have small dimensions, which facilitates operational measures. In the manufacture of the case, stainless steel or plastic is used. Although synthetic materials add strength characteristics, from the point of view of reliability, it is still more profitable to buy metal assemblies. But in this case, one must also prepare for an increase in mass. The function of the internal suction device is performed by a centrifugal pump. Depending on the version, it can be either a small apparatus for working with relatively clean water, or a productive drainage pump with a float switch that can effectively deal with contaminated compounds. True, the very concept of pumps of this type makes it possible to work with large particles and abrasives in the aquatic environment. For this reason, most models come with a wide working camera for optimal throughput.
Principle of operation
A traditional drainage pump is immersed in water and begins to pump it. But in this case, you should pay attention to the float switch, which makes its corrections to the process. The device is designed to protect against dry running, which insures against breakage. The usual way of operating is to assume that the pump will run until it is stopped by the operator. For this reason, even after emptying the tank, the unit can continue to fulfill its function, which is very harmful for the technical filling. This risk completely eliminates the drainage pump with a float switch, the principle of which allows automatic shutdown. The need for a stop is signaled by the barorel controller, which is located in the float device and reacts to the water level. The autonomy of the work of such units goes far beyond one-time events. The pump can be left in the flooding area, and each time it reaches a certain water level, it will perform pumping.
Main characteristics
The main indicator of the efficiency of the drainage pump is productivity. Models for domestic use can provide pumping with a productivity of the order of 140-170 l / min. For the right choice, you should evaluate the amount of water that will need to be serviced, and compare this value with time. The higher the productivity, the less time will be spent on the workflow. It is necessary to take into account the direction of the pressure, which will be provided by the drainage pump with a float switch. The instruction for such units usually gives the characteristics of the fence in the calculation that the vertical pressure per 1 m corresponds to a similar force in the vertical position, but already at a distance of 10 m.
Manufacturer's Reviews
The market is divided into models for professional and domestic purposes. For private needs, Gardena, Metabo, Al-ko Drain and others are recommended. Separately, users praise the drain pump with a float switch "Dzhileks", which is represented by compact, but effective in operation modifications. A lot of positive reviews about the Karcher brand. Some of the models of this brand are capable of draining to a level of 5 mm.
As for professional technology, Speroni is the leader in this segment. Although the models of this company differ in massive sizes, in terms of reliability this is one of the best options. If you need an apparatus for working in problem areas with a high content of impurities in water, then you should choose this particular drainage pump with a float switch. Reviews note that it can be used to organize a drainage system not only within a private site, but also in specialized farms.
Pros and cons of the unit
The design of drainage pumps allows them to be used in a wide variety of fields - from pool maintenance to watering a garden bed and draining a basement. Manufacturers strive to endow such equipment with small cases, which also increases the ergonomic advantages of pumps. Deficiencies of equipment are already evident in the process of prolonged use. Since the drainage pump with a float switch is designed for operation in close contact with water, after some time, traces of deformation on the surfaces of the housing can be detected. We can say that manufacturers increase the durability of units through the use of high-strength and hardy materials, but aggressive environments in the long term leave no chance for high-quality plastic and metal alloys.
Conclusion
The organization of a drainage system requires an integrated approach to the selection of its components. In most cases, a drainage pump with a float switch is used as the basis, but for its full functioning a whole set of accessories should be purchased. It can be adapters, hoses, fittings, fasteners and other devices that increase the reliability and productivity of the drainage function. Also, the latest versions of the pumps are equipped with automatic systems, which makes it easier to control the unit from the user.
