Grundfos drainage pump with float. Choosing a drainage pump and its characterization for water disposal in a private house. Drainage of soil by Grundfos

Water plays an important role in human life, but in some cases serious problems arise from it. During floods, melting snow, abundant rains, raising groundwaterThe breakthrough of water pipes occurs large number Water, which is able to fill up the foundation of buildings, impoverishing their basements.

For help in such situations, the drainage pump is perfect for the elimination of flooding. Using such a pump, you can easily make a liquid pumping without much effort even having some contamination.

1 types of drainage pumps

The drainage pump is a pump that is intended for pumping fluid in large volumes, where the content of mechanical impurities does not exceed 5-10%. Drainage pumps are designed to pump fluid (drainage) from pools, basements, kittlers, flooded sites, mines, industrial systems and other liquid cleaning facilities.

All pumps intended for drainage are divided into:

superficial;
submersible.

Surface pumps are installed outside the tank with liquid, on the surface of the Earth. To fulfill waste, the hose or pipe is descended to the bottom of the tank. To automatically turn on the engine off, the float mechanism is supplied to the start lever. The float mechanism automatically monitors the change in the level in the pit.

With a change in the specified level of stock, drainage equipment automatically turns on and the liquid is absorbed and the release of it beyond the reservoir. Due to its mobility, surface pumps can easily be moved to the right place, in case of failure in the work or breakage.

Submersible pumps on the principle of work are no different from superficial.

The submersible pump has several structural differences. Unlike superficial, where bodies are performed in the inlet hose, the submersible pumps are lowered into the pitover with a liquid and pumping through the suction hole in the bottom of the pump.

To perform the described tasks, the Grundfos drainage pump is suitable, who proved himself with best side in the market of similar equipment. Due to the fact that the equipment copes perfectly with its tasks and has excellent quality, it has high demand from the consumer.

1.1 Concern Grundfos.

Grundfos (Grundfos) is a company that produces pumping equipment, its main office is located in the Danish city of Bierryngbro. The number of personnel of this company by 2009 numbered 18 thousand people in different countries. Concern Grundfos per year manufactures up to 16 million pumping equipment units.

submersible pumps, marking - SP;
centrifugal pumps, marking - CR;
circulation pumps, UR marking.

In addition to the manufacture of pumping units in plant production factories, the production of electric motors for pumps and components for them is laid.
Grundfos was founded back in 1945. Her founder was Paul Du Jensen. First, the company is called Bjerringbro Pressestoberi OG Maskinfabrik, which meant a press cast factory and machine processing in Bierrybro. But the years went and the name changed several times, while in 1967 she did not receive her present name.

Currently, the company's resources allow you to be a world leader in the production of pumping equipment and its components, as well as dictate fashion to the development of technologies for water treatment.

1.2 Basic data pumps Grundfos

models for working with pure or weakly dilapidated water;
models for working with dirty water.

It can be said that the first category of these devices is designed for pumping clean water, which may contain particles in solid form no more than 5-10 mm in diameter. The second category of equipment performs the same functions, but with particles from 10 mm and above. Submersible drainage grundfos pumps I also have its own model ranks in which the sewer and well rows are included.

Grundfos drainage pumps in certain applications are successfully followed by the following tasks:

watering systems;
water supply systems and water supply;
obtaining excessive water from Kotlovanov, pittors, flooded basements, pools.

Drainage submersible Grundfos pump can be relevant when performing irrigation, the main thing is to be water tank (well, tank, barrel, bucket).
Drainage pumps in their structure are centrifugal.

Construction of units:

Two housing compartments: pumping department and a sealed camera in which the electric motor is built.

Almost all models are made of stainless steel, with the exception of some cases of cast iron (for example, in the manufacture of sewer units). There are some types of low-budget options, which are intended for use in a non-aggressive environment from clean water Performed in a plastic case. In the manufacture of impeller, it is used as a material, or a technopolymer, or stainless steel.

A convenient handle is installed on each model from above, which simplifies transportation, it is possible to suspend the cable to immerse the pump into the water. To prevent pollution with large mechanical elements, the pump compartment is protected by a mesh filter before the suction chamber.

2 types and description

In their characteristics drainage pumps Grundfos is largely superior to the installation of their competitors who are used in everyday life. Basically, such an advantage is achieved by a high resource of operation and reliability, which have Grundfos Unilift pumping devices. They are ideal for pumping water from deep wells whose depth reaches 230 meters.

According to the Grundfos Unilift price range, it is impossible to be called perfect for the consumer, as it is high, but it is leveled high quality equipment. Pump equipmentGrundfos is produced by several episodes:

SPO series.
SQ Series.
SQE series.
Series SP A (1 x 220V).
SP A series (3 x 400V).

SpO is performed from materials that carry corrosion and have a long operational period. They can be used in specific conditions with increased pressure Thanks to a special design. Capable water supplying functions in private and country lanes.

The submersible SQ pump is designed to pump out water from mines, wells, which have a different neck diameter. Due to small size, the problem of operation occurs during operation with these pumps. Borehole pumps There are centrifugal and submersible. Excluded unplanned translation of installation on idling. This is due to the presence electronic elements protection.

Grundfos pumps Drainage SQE do not have differences from the previous series. The only difference is the presence of a closet management Grundfos. CU 301. With this cabinet, you can work with submersible equipment and control it completely, adjust the speed of the engine and the pressure in the system.
Models from the SP A series (1 x 220v) are designed to supply drinking, plumbing, marine and technical water in residential buildings Irrigation systems from tanks or sources with water. The proportion of impurities or sand in the transported water should not exceed 50 g / m 3.

SP A (3 x 400V) is almost the same by parameters with the previous series. They are intended for the same purposes, but with large volumes of water and are designed for greater power, thereby saving time.

if you have vacation homeYou know perfectly well how important questions need to be solved for its arrangement. One of them is the organization of drainage. Household drainage pump is needed in a private house. Take the stocks from washing dishwasher And the soul, remove the water from the sleeved basement, the pool or garden pond - all this will make the drainage pump for the house. Perfect solution For household needs - automatic drainage pump. The most common option is a submersible drainage pump with a built-in float. If the water rises, the float mechanism includes a pump if the water is gone - turns off.

What drainage pumps can be used?

Submersible drainage pumps differ in many parameters - according to the material from which they are made; By the size of the particles they pass; on expenditure characteristics; For use and features of use.

The material from which the pump is made directly affects its reliability. Submersible drainage pumps can be made of composite materials in combination with elements from of stainless steel Or fully made of stainless steel. For example, Grundfos pump Unilift CC. It has a strainer made of stainless steel. The main parts of the pump, for example, coupling and housing, are made of molded composite materials. All the details of the pumps Unilift KP., Unilift AP (B) Contacting with water, made of stainless steel. Due to this pumps have high wear resistance.

The particle size that filters the submersible drainage pump is another important indicator. So, pumps Unilift CC. and work with small particles up to 10 mm. They are suitable for pumping conditionally clean water, for example, from washing machines, Washing units, shower, from rivers and ponds, sleek rooms (talking about pumping feces from sewage does not go).

You can choose a pump for your requirements using the search and equipment search and selection program. Grundfos Product Center. (GPC) http://product-selection.grundfos.com.

Application I. constructive features The pump also largely determine the choice of model. So, for hot water Drainage pump is suitable Unilift KP.. It is made of stainless steel, can work with water heated to 95 degrees and is suitable for short-term hot water pumping. Water with a large air content better than other pumps pump Unilift CC. - The air trap is built into his handle. The same pump is well suitable for pumping water from the floor to a level of 3 mm. For pumping water with increased sand / suspension better use pump Unilift AP (B) .

Drainage pump management is just

Controlling the drainage pump can be manual or automatic. Automatic, of course, more convenient and more reliable - if the pump will work without water, it can fail. Usually automatic drainage pumps are equipped with a float switch. To control the drainage pump, it is enough to simply set the desired level of inclusion / off. The adjusting lever (the same float switch) is kept at the water level. If it is lowered, the pump automatically turns off. If rises - turns on. Control of the drainage pump of a more complex modification
performed through a special control cabinet.

If you have determined with the type of drainage pump and are ready to make a purchase, you are to help the advice of a professional. Grundfos sales engineer Ekaterina Semenova says what to pay attention to when choosing a submersible drainage pump.

Quality and safety of execution. Submersible drainage pump operates in water and with electricity. therefore main moment - Tightness of cable entry. If the connection is not tightly tightly, an accident may occur. Grundfos has additional protection for all drainage pumps - a special rubber layer that makes the connection as secure as possible.

Expendable pressure characteristics. How to calculate them - see above.

Orientation of the pressure pipe. Two options are possible - horizontal orientation or vertical. Choose the right orientation is especially important if the pump is embedded in an existing drainage system. If the orientation of the pressure pipe does not coincide, to connect with wiring use flexible hose. User pumps Grundfos Unilift CC. There is a simpler option. About a year ago there was an updated modification of this pump with two pressure pipes - for a vertical and horizontal connection. The desired nozzle is connected to the wiring, and the one that is not used is closed with a plug (it comes in the kit).

Board for application

Avoid breakdowns and extend the service life of the drainage pump, by setting on a special platform by 2-3 cm above the bottom or floor surface. Despite the fact that the performance of the drainage pump is low, in the arid period can be used for irrigation. You just need to send using a pump collected water In the watering system.

Completion and additional options. The more complete components are included with the pump, the better. Complete with Grundfos Unilift CC. , in addition to two pressure pipes and plugs, there is an adapter nozzle, which allows you to adjust the diameter of the pipe, check valvewhich does not allow the reserved fluid to go back to the pump (many manufacturers it is not included), removable suction grid, which allows you to pump water to a level of 3 mm. Additional options for drainage pump Unilift CC. - Built-in thermal protection, mounted in the handle the air vent and the cooling system of the electric motor with pumped water.
