Drain pump with float switch: principle of operation and feedback

With the expansion of optional support, modern pumps are becoming more functional. The presence of automation and the possibility of connecting several pumping systems into one complex significantly increases the operational advantages. The wave of technological development and traditional water intake units were covered, as a result of which a drain pump with float switch and electronic control appeared. The introduction of new systems allowed owners of such devices to carry out economic tasks with great comfort. This may include pumping water from the basement, emptying reservoirs, watering operations, etc.

Pump unit

Most models have small dimensions, which facilitates operational activities. The case is made of stainless steel or plastic. Although synthetic materials are added in strength characteristics, from the point of view of reliability, it is still more profitable to purchase metal aggregates. But in this case it is necessary to prepare and to increase the mass. The function of the internal suction device is performed by a centrifugal pump. Depending on the version of the version, it can be either a small device for working with relatively clean water, or a productive drain pump with a float switch that can effectively cope with contaminated compounds. True, the very concept of pumps of this type makes it possible to work with large particles and abrasives in the water environment. For this reason, most models are equipped with a wide working chamber for optimum throughput.

Principle of operation

A traditional drainage pump is immersed in water and begins to pump it out. But in this case it is worth paying attention to the float switch, which makes its corrections in the process. The device is designed to protect from work in the "dry run" mode, which insures against breakage. The usual way of operation assumes that the pump will work until the operator stops it. For this reason, even after emptying the tank, the unit can continue to perform its function, which is very harmful for the technical stuffing. This risk completely excludes a drain pump with a float switch, the principle of operation of which allows automatic shutdown. The need to stop signals the barrel regulator, which is located in the float device and reacts to the water level. The autonomy of the operation of such units goes far beyond the scope of one-time events. The pump can be left in the area of flooding, and each time it reaches a certain level of water, it will perform pumping.

Main characteristics

The main indicator of the efficiency of the drainage pump is the productivity. Models for domestic use can provide pumping with a productivity of about 140-170 l / min. For the right choice one should estimate the volumes of water that will need to be serviced, and compare this value with time. The higher the productivity, the less time spent on the workflow. One should also take into account the directivity of the head, which will provide a drain pump with a float switch. The instruction for such units usually cites the characteristics of the fence from the calculation that the vertical head of 1 m corresponds to a similar force in the vertical position, but at a distance of 10 m.

Reviews of manufacturers

The market is divided into models for professional and domestic purposes. For private needs, the brands Gardena, Metabo, Al-ko Drain and others are recommended. Separately, users praise the drain pump with the float switch "Dzhileks", which is represented by compact but effective modifications. A lot of positive feedback about the brand Karcher. Some of the models of this brand are able to perform draining to a level of 5 mm.

As for professional equipment, in this segment Speroni is in the lead. Although the models of this company differ in massive sizes, in terms of reliability it is one of the best options. If you need a device to work on problem areas with a large content of impurities in the water, then you should choose this drain pump with a float switch. The reviews point out that it can be used to organize a drainage system not only within a private plot, but also in specialized farms.

Pros and Cons of the Unit

The design of drainage pumps allows them to be used in a variety of areas - from maintenance of pools to watering the garden patch and draining the basement. Manufacturers tend to endow this technique with small cases, which also increases the ergonomic advantages of pumps. The shortcomings of the equipment are manifested already in the process of long-term use. Since the drain pump with the float switch is designed to operate in close contact with water, after a while, it is possible to detect deformation marks on the surfaces of the housing. We can say that manufacturers increase the durability of aggregates through the use of high-strength and hardy materials, but aggressive environments in the long run do not leave a chance for both high-quality plastic and metal alloys.

Conclusion

The organization of the drainage system requires an integrated approach to the selection of its components. As a basis, in most cases, a drain pump with a float switch is used, but for its full functioning it is necessary to purchase a whole set of accessories. These can be adapters, hoses, fittings, fasteners and other devices that increase the reliability and productivity of the drainage function. Also, the latest versions of pumps are equipped with automatic systems, which make it easier for the user to control the unit.
