Drainage pumps- designed for pumping drainage and groundwater located in residential buildings, industrial enterprises, sewage pumping stations. Drainage pumps are widely used, while performing the most diverse - simple and complex tasks, both domestic and related to the performance of construction work, in agricultural and industrial sectors of various kinds.
For example, drainage devices are widely used:
The popularity of drainage equipment is easily explained by the mass of available positive aspects, among which the following should be highlighted:
The drainage pump equipment is designed to lift water over a short distance due to the fact that these pumps are not able to create high pressures. You need to know that pumps of this type are quite difficult to maintain and repair.
There are different types of drainage pumps for supplying and pumping water: domestic and industrial drainage pumps, which explains the scope of their use.
A household drainage pump is used to pump out liquid from flooded buildings, rooms and containers of various types, for example, aquariums, swimming pools, etc.
The types and types of drainage pumps are determined by their purpose and areas of application. They are:
When carrying out various works in industrial and civil construction, very often flooding of pits, trenches, pits occurs, which occurs after heavy rains, with a close location of groundwater and in the presence of many other factors. However, construction work should not stop because of this. To drain trenches, pits and pits, water drainage pumps are used, capable of pumping out liquids with mechanical impurities, the content of which reaches 10%. Such pumping drainage equipment can also be used for cleaning silted ponds, and it is also permissible here to use submersible and semi-submersible drainage pumps. Industrial drainage pumps are used, as a rule, to pump out sewage water, industrial wastewater and rainwater in large volumes. Drainage pumps are made of stainless steel or cast iron.
Sewage pumps of the drainage type are divided into:
The technical indicators of these pumps ensure their use on a large industrial scale, as well as with limited volumes in the private sector. Today on the market you can find drainage pumps capable of draining containers to a liquid level of 1 millimeter. Such pumps run dry, so their motors have special protection to ensure that they work in this mode.
Often, basements and cellars in any house, be it multi-apartment or private, are reliably protected from flooding with the help of a well-functioning drainage pump. After torrential rains and breakthroughs of water supply lines, due to clogging of the drainage equipment system, it is often this part of the structure that is flooded, which entails the development of unsanitary conditions in the house and contributes to the further destruction of the foundation. Eliminate the consequences of flooding and ensure that water is pumped out by drainage pumps, the direct purpose of which is to pump out and drain water, as well as various kinds of wastewater with a large amount of different impurities from various reservoirs. These can be pits, mines, drain pits, domestic sewage systems, industrial systems and other treatment facilities and installations. Drainage pumps pump out or divert fecal wastewater when servicing multi-storey buildings. Despite the fact that both the drainage and fecal pumps operate in essentially the same way in similar environments, there is a fundamental difference between them: for each of them, the permissible value of solid impurities in the effluents has been established. For a drainage pump, this size is 3-12 mm in diameter and up to 120 mm for pumps that pump out sewage in large volumes. The fecal pump, on the other hand, works with liquids in which there are either no solid particles at all, or they are small in size. A feature of drainage equipment for working with liquids with impurities and suspensions is the presence of knives and other cutting mechanisms, which, during the operation of the pump, act as suspensions grinders. The design of the impeller, which the drainage pumps are equipped with, can be semi-open, mono-channel or vortex.
