The assortment of special pumps capable of pumping liquids( including those containing various suspensions) is significant. This often leads to a substitution of concepts. If we are talking only about dirty water, then it is understood that the drain pump must cope with solid fractions of a relatively small amount, but in no way with rags, threads, paper and the like. Therefore, confuse such models with fecal should not.
On what criteria it is necessary to determine the feasibility of choosing a drainage pump for dirty water, and will be described in the article.
Practice shows that such devices in the private sector have limited application. With the help of drainage pumps, household problems such as draining a basement room or a cellar( in case of underflooding), a pool( if necessary, inspecting the bowl, servicing it or repairing it) and in a number of other cases are solved. It is often necessary to pump out clean water, but with the risk of contamination of the pump itself - for example, from a well before scraping off the walls of the trunk of various deposits.
Therefore, the frequent recommendations "first determine what a drain pump is for" is not entirely correct. It should be universal in use, and at the same time its cost should not be burdensome for the family budget, because such a product is operated irregularly, but only if necessary. Here from these positions and we will consider the order of choice, focusing only on drainage pumps for domestic use.
Type of drainage pump
Submersible model
The name and the specificity of the installation of the drainage pump are clear - at a certain depth. This characteristic is indicated in the passport for the device.
- Pumps of this design are of sufficient capacity. This is superior to drainage analogs of the surface type.
- Submersible products are able to function under severe water pollution. The permissible size of solid fractions of household models is up to 5 mm.
Price
The cheapest price starts from 2 450 rubles. For example, the Russian pump Drainage. The power is small - 0.2 kW, but the maximum size of the fractions is 5 mm.
Surface Pump
- The special feature of the application is that the product body is installed next to the reservoir( reservoir), and only part of the sleeve is placed in it. The maximum depth of the intake of liquid is about 4.5 m. If it is too dirty, this indicator decreases.
- Such drain pumps are not very powerful and do not withstand intensive use. They are designed for use from time to time, and are able to work with water pollution only in small fractions( usually up to 1.5 mm).
- The second drawback - operation is possible only at plus temperatures. Therefore, if you need to use in winter, the pump must be in the room. And, necessarily heated. The reader will determine how important this is.
Price
The minimum price is about 9 100 rubles. For the private sector, a good option is the drain pump of the Burun model. With a power of 0.75 kW and a capacity of 60 liters / minute, it costs 16,485 rubles.
Drainage pump housing
-
Metal - much stronger than plastic. However, there are also disadvantages - increased noise during the operation of the drain pump and the risk of corrosion. - Plastic - light weight and kit price. This is a plus. Experts consider the lack of reliability of a drainage pump with a housing made of such a material to be a disadvantage.
Design features of
- Location of the suction nozzle. This applies to drainage submersible models. If it is lower, then such a pump will quickly be clogged with a different haze and dirt. At the top location, it is not possible to drain the container to the bottom( or floor space).
- Overheating protection. "Autostop" is provided by a float, which is connected to the power switch. Such automation, though, raises the price of the drain pump, but excludes its work( and breakdown) at idle. For example, with full pumping of water from the tank.
- Performance. As practice shows, for domestic use within 100 l / min is enough. Sometimes such pumps are installed in drainage systems with forced drainage of water. In this case, the indicated power may not be enough.
Perhaps this is all you need to know to properly choose a drain pump for pumping dirty water. All other information is easy to verify in the passport of the device. By the way, in this document - and recommendations for use. The fact is that each type of pump is a large range of products. And the difference between the samples - not only in specific characteristics, but also in various "bells and whistles", which manufacturers are not stingy. If the drain pump is able to perform the work for which it is purchased, it can be safely taken.
