Before purchasing suburban area experts always recommend paying special attention to hydrogeological characteristics of the soil . Technicians constructing electric centrifugal Grundfos drainage pumps(Grundfos), they know what a risk over-wetting the soil can pose to a garden.

So, the cause of waterlogging can be close location lakes to the area where estate, field, and meadow lands are located. In these conditions Grundfos submersible drainage pumps for pumping dirty water prevent a range of hazards.

Prevention through drainage

One of these dangers is insufficient air , which plant roots need. Without air access, the development of trees and flowers stops. They need many microelements, instead of which the soil gives the plants salts that have time to dissolve in water. Submersible Grundfos drainage pumps for water from wells are designed in such a way as to prevent processes harmful to almost any type of planting.

Another risk that comes from waterlogging the soil is deep freezing of plant roots , which can occur during the cold season. In such conditions, plantings die irrevocably - this is confirmed by the experience of gardening in countries characterized by winter frosts.

Soil drainage using Grundfos devices

Risk of soil waterlogging

Before purchasing a suburban plot, experts always recommend paying special attention to the hydrogeological characteristics of the soil. The technicians who design Grundfos electric centrifugal drainage pumps know the risks that over-wetting the soil can pose to your garden.

Thus, the cause of waterlogging can be the close location of the lake to the area where there are estates, fields, and meadows. In these conditions, Grundfos submersible drainage pumps for pumping dirty water prevent a number of dangers.

Prevention through drainage

One of these dangers is the insufficient amount of air that plant roots need. Without air access, the development of trees and flowers stops. They need many microelements, instead of which the soil gives the plants salts that have time to dissolve in water. Grundfos submersible drainage pumps for well water are designed to prevent processes that are harmful to almost any type of planting.

Another risk that comes with waterlogging the soil is deep freezing of plant roots, which can occur during the cold season. In such conditions, plantings die irrevocably - this is confirmed by the experience of gardening in countries characterized by winter frosts.

if you have Vacation home, you know very well how many important issues need to be resolved to arrange it. One of them is the organization of wastewater disposal. A household drainage pump is necessary in a private home. Drain waste from the washing machine, dishwasher and shower, remove water from a flooded basement, swimming pool or garden pond - a drainage pump for the home will do all this. The perfect solution for domestic 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 turns on the pump; if the water goes down, it turns it off.

What kind of drainage pumps can I use?

Submersible drainage pumps differ in many ways - the material from which they are made; by the size of the particles they allow through; according to flow-pressure characteristics; on application 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 stainless steel elements or made entirely of stainless steel. For example, Grundfos pump Unilift CC has a mesh filter made of stainless steel. The main parts of the pump, such as the coupling and housing, are made of molded composite materials. All pump parts Unilift KP, Unilift AP (B), in contact with water, are made of stainless steel. Due to this, the pumps have high wear resistance.

The size of the particles that the submersible drain pump filters is another important indicator. Yes, pumps Unilift CC and work with small particles up to 10 mm in size. They are suitable for pumping conditionally clean water, for example, from washing machines, washing units, showers, from rivers and ponds, flooded premises (we are not talking about pumping feces from sewers).

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

Application and design features The pump also largely determines the choice of model. So, a drainage pump is suitable for hot water. Unilift KP. It is made of stainless steel, can work with water heated up to 95 degrees and is suitable for short-term pumping of hot water. A pump can pump out water with a high air content better than others. Unilift CC– an air vent is built into its handle. The same pump is well suited for pumping water from the floor to a level of 3 mm. To pump water with an increased content of sand/suspension, it is better to use a pump Unilift AP (B) .

Controlling the drain pump is easy

The drain pump control can be manual or automatic. Automatic, of course, is more convenient and reliable - if the pump operates without water, it may fail. Typically, automatic sump pumps are equipped with a float switch. To control the drainage pump, simply set the desired on/off level. The adjustment lever (the same float switch) is kept at water level. If it goes down, the pump automatically turns off. If it rises, it turns on. Control of a more complex drainage pump
performed through a special control cabinet.

If you have decided on the type of drainage pump and are ready to make a purchase, professional advice will help you. Grundfos sales engineer Ekaterina Semenova explains what you need to pay attention to when choosing a submersible drainage pump.

Quality and safety of execution. The submersible sump pump works with water and electricity. Therefore, the main point is tightness cable entry. If the connection is not tight enough, an accident may occur. Grundfos has additional protection on all drainage pumps - a special rubber layer that makes the connection as safe as possible.

Flow and pressure characteristics. How to calculate them - see above.

Discharge pipe orientation. There are two options – horizontal orientation or vertical. Choosing the correct orientation is especially important if the pump is being built into an existing drainage system. If the orientation of the pressure pipe does not match, use a flexible hose to connect to the wiring. For Grundfos pump users Unilift CC there is a simpler option. About a year ago, an updated modification of this pump appeared with two pressure pipes - for vertical and horizontal connections. The required pipe is connected to the wiring, and the one that is not used is closed with a plug (it is included in the kit).

Application advice

You can avoid blockages and extend the service life of the drainage pump by installing it on a special platform 2-3 cm above the bottom or floor surface. Despite the fact that the performance of the drainage pump is low, it can be used for irrigation during dry periods. You just need to use a pump to direct the collected water into the irrigation system.

Equipment and additional options. The more additional components included with the pump, the better. Complete with Grundfos Unilift CC, in addition to two pressure pipes and a plug, there is an adapter nozzle that allows you to adjust the diameter of the pipe, check valve, which does not allow the withdrawn liquid to go back into the pump (for many manufacturers it is not included in the kit), a removable suction mesh that allows you to pump out water to a level of 3 mm. Additional drain pump options Unilift CC– built-in thermal protection, an air vent built into the handle and a cooling system for the electric motor with pumped water.

Availability of technical support. No matter how technically literate a user is, he may need technical support at any time. It is always available to users of Grundfos pumps. Consultation can be obtained both on the choice of pump, and on the installation of equipment and its further operation. Any customer request is answered almost instantly and with very high quality. For the convenience of users, the Service 24 program operates: the consumer of Grundfos products calls by phone hotline(the number is indicated on the warranty card), it is switched to the nearest service center, a service specialist comes to the client within 24 hours and, if the case is under warranty, eliminates the fault on the spot or replaces the pump with another one, and takes the old one for repair. An option is possible when the client himself brings the pump to the service center - if it is more convenient for him. In this case, the terms of service are the same. If the case is not covered by warranty, the client will also not be left without attention and technical support.

Water plays an important role in human life, but in some cases, serious problems arise from it. During floods, melting snow, heavy rains, rising groundwater, water pipeline breaks and formation occurs large quantity water, which can wash away the foundations of buildings, flooding their basements.

To help in such situations, to eliminate flooding, a drainage pump is perfect. Using such a pump, you can easily pump out liquid without special effort even if it has some degree of contamination.

1 Types of drainage pumps

Drainage pump is a pump that is designed to pump out liquid in large volumes, where the content of mechanical impurities does not exceed 5-10%. Drainage pumps designed for pumping liquid (drainage) from swimming pools, basements, pits, flooded areas, mines, industrial systems and other installations for liquid purification.

All pumps intended for drainage are divided into:

• superficial;
• submersible

Surface pumps are installed outside a reservoir of liquid, on the surface of the earth. To pump out waste, a hose or pipe is lowered to the bottom of the tank. To automatically turn the engine on and off, a float mechanism is connected to the start lever. The float mechanism automatically monitors changes in the level in the pit.

When the set level of wastewater changes, the drainage equipment is automatically turned on and liquid is sucked in and discharged outside the tank. Due to its mobility surface pumps You can easily move it to the right place in case of malfunction or breakdown.

Submersible pumps operate in no way different from surface pumps.

The submersible pump has several design differences. Unlike surface ones, where suction is carried out by an inlet hose, submersible pumps are lowered into a pit with liquid and pumped through the suction hole in the bottom of the pump.

A Grundfos drainage pump is suitable for performing the described tasks, which has proven itself with best side on the market of similar equipment. Due to the fact that the equipment copes with its tasks perfectly and is of excellent quality, it is in high demand among consumers.

1.1 Grundfos Group

Grundfos is a company that produces pumping equipment, its head office is located in the Danish city of Bjerringbro. The number of personnel of this company by 2009 totaled 18 thousand people in different countries. The Grundfos concern produces up to 16 million pumping equipment units per year.

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

In addition to the production of pumping units, the production capacity of the plants includes the production of electric motors for pumps and components for them.
Grundfos was founded back in 1945. Its founder was Paul Du Jensen. At first, the company was named Bjerringbro Pressestoberi og Maskinfabrik, which meant Press Casting and Machining Factory in Bjerringbro. But the years passed and the name changed several times, until in 1967 it received its current name.

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

1.2 Basic data of Grundfos pumps

• models for working with clean or slightly contaminated water;
• models for working with dirty water.

We can say that the first category of these devices is designed for pumping clean water, which may contain solid particles no more than 5-10 mm in diameter. The second category of equipment performs the same functions, but with particles of 10 mm and above. Grundfos submersible drainage pumps also have their own model ranges, which include sewer and well ranges.

Grundfos drainage pumps successfully perform the following tasks in certain areas of application:

• irrigation systems;
• water supply and water supply systems;
• pumping out excess water from pits, pits, flooded basements, and swimming pools.

A Grundfos submersible drainage pump can be useful when watering, the main thing is that there is a container with water (well, tank, barrel, bucket).
Drainage pumps are centrifugal in structure.

Unit design:

Two compartments of the housing: a pumping section and a sealed chamber 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 sewerage units). There are some types of low budget options, which are intended for use in non-aggressive environments With clean water are performed in plastic case. In the manufacture of the impeller, either technopolymer or stainless steel is used as a material.

Each model is equipped with a convenient handle on top, which simplifies transportation; you can attach a cable to it to immerse the pump in water. To prevent contamination by large mechanical elements, the pump compartment is protected mesh filter in front of the suction chamber.

2 Types and description

In terms of their characteristics, Grundfos drainage pumps are in many ways superior to the installations of their competitors, which are used in Everyday life. This advantage is mainly achieved by the high service life and reliability that Grundfos unilift pumping units have. They are ideal for pumping water from deep wells, the depth of which reaches 230 meters.

In terms of the price range, Grundfos unilift cannot be called ideal for the consumer, since it is high, but this is leveled out high quality equipment. Pump equipment which is produced by Grundfos is divided into several series:

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

SPOs are made from materials that resist corrosion and have a long lifespan. service life. They can be used in specific conditions with high pressure due to their special design. Capable of performing water supply functions in private and country houses.

The SQ submersible pump is designed for pumping water out of mines and wells that have different neck diameters. Due to their small size, there are no operational problems when working with these pumps. Well pumps There are centrifugal and submersible. Unplanned transfer of installation to idling. This is due to the presence of electronic security elements.

Pumps Grundfos drainage SQE are no different from the previous series. The only difference is the presence of a cabinet Grundfos control CU 301. Using this cabinet, you can work with submersible equipment and fully control it, regulate the engine speed and pressure in the system.
Models from the SP A series (1 x 220V) are designed to supply drinking water, sanitary, marine and process water V residential buildings irrigation systems from reservoirs or water sources. The proportion of impurities or sand in the transported water should not exceed 50 g/m3.

SP A (3 x 400V) are almost identical in parameters to the previous series. They are designed for the same purposes, but with larger volumes of water and are designed for greater power, which saves time.
