The pump drainage with a float Grundfos. Grundfos drainage pumps

When solving the issue of water supply to a private house or suburban area their owners often face the almost complete impossibility of doing this without a well device. But in order to extract water from there, special equipment is required - such as wells Grundfos pumps.

Why do the vast majority of buyers in Moscow and the region prefer Grundfos well pumps? There are several reasons for the huge popularity of the Danish company:

• The equipment is made of durable and reliable materials;
• The mechanism of technology works like an expensive watch;
• Each Grundfos submersible well pump lasts several times longer than its counterparts;
• The price of equipment remains as affordable as always;
• Ease of use and operation.

There are a few more important points why you should buy a Grundfos well pump, and we'll talk about this further.

Equipment Features

Among the important parameters of Grundfos Spo it is worth noting:

• long service life due to high-quality manufacturing and application in the design of stainless steel;
• a safety system in the form of a float switch that prevents Grundfos well pumps from running idle and thus protects their motors from overload;
• the ability to pump water from a well or tank up to the lowest water level, since it is taken well pumps Grundfos from below.

Acquisition features

The purchase of Grundfos well pumps should be carried out from authorized dealers of this brand. One of them is the company "TeplovodService". We can provide our customers with not only advisory support on all issues related to Grundfos well pumps, but also help with their maintenance, both during the warranty period (2 years) and after it.

Before purchase suburban area experts always recommend paying special attention to hydrogeological characteristics of the soil . Technicians designing electric centrifugal Grundfos drainage pumps(Grundfos), they know what a risk for a garden or vegetable garden can be waterlogging of the earth.

So, the cause of waterlogging can be proximity lakes to the site where the estate, field, 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 not enough air required by plant roots. Without access to air, the development of trees and flowers stops. They need a lot of trace elements, instead of which the soil gives the plants salts that have had time to dissolve in water. Submersible Grundfos drainage pumps for water from wells are designed in such a way as to prevent processes that are harmful to plantings of almost any type.

Another risk that waterlogged soil carries is deep freezing of plant roots which can occur during the cold season. Under such conditions, plantings perish irrevocably - this is confirmed by the experience of horticulture in countries that are characterized by winter frosts.

Soil drainage with Grundfos

Global manufacturers consider submersible Grundfos mud pumps technical standard, which is absolutely true. These are highly efficient devices designed specifically to prevent excessive wetting of land plots of various sizes.

Worldwide self-priming pumps for dirty water (drainage and sewage) Grundfos - ideal designs for landscape and park planning, capable of quickly drying the soil, removing excess moisture from it. These are indispensable tools in the system of landscaping areas and paving decorative garden paths.

household Grundfos drain pumps with float- those devices, without which the construction of buildings is unthinkable: without processing the soil for the foundation, it is impossible to build strong house. Grundfos devices create a system that is imperceptible at first glance, in time preventing stagnation of liquids .

Leaders farms many countries note: to buy a manual (float) drainage pump of this brand means to reliably guarantee the soil from excessive waterlogging. Submersible drainage pump Grundfos Unilift (Unilift) especially useful in cases where the site is located in a lowland, near a slope or on clay soil.

Individual consultations of specialists

To date, these are devices that have the most optimal specifications . The sale of drainage pumps is widely established in our country.

Most often they are installed in places where there is a risk of flooding. Their float also serves as a sensor that regulates the operation. Fecal drainage pumps price which fully corresponds to the operational qualities, reliably protected from dry running and also do not need constant maintenance.

Grundfos devices do not require additional expensive materials. These aggregates are called universal - they adapt to different types relief.

With devices from a Danish manufacturer, excess liquid becomes easy to drain outside the site. If, before operating a machine such as Liftaway B, specialist advice is received, then the operation of the device will bring maximum benefit to the site.

To this end, the RusPumps project organized a system of continuous consultations of professionals on the choice of one or another type of Grundfos apparatus. Our project specialists help each client to take into account specific drainage needs and optimize your costs.

if you have Vacation home, you know perfectly well how many important issues need to be resolved for its arrangement. One of them is the organization of water disposal. A household drainage pump is needed in a private house. Drain drains from washing machine dishwasher and shower, to remove water from a flooded basement, pool or garden pond - all this will be done by a drainage pump for the house. The ideal solution for household needs is an 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 is gone, it turns it off.

What drainage pumps can be used?

Submersible drainage pumps differ in many ways - in the material from which they are made; by the size of the particles they pass 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 combined with stainless steel elements or completely made of stainless steel. For example, a Grundfos pump Unilift CC It has a mesh filter made of stainless steel. The main parts of the pump, such as the coupling and casing, 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 a high wear resistance.

The size of the particles that the submersible drainage 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, e.g. 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 for your requirements using the equipment search and selection program Grundfos Product Center(GPC) http://product-selection.grundfos.com.

Application and design features pump also largely determine the choice of model. Yes, for hot water suitable drain pump 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. Water with a high air content is pumped out better than others by the pump 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. For pumping water with an increased content of sand / suspension, it is better to use a pump Unilift AP (B) .

Drain pump control made easy

The control of the drainage pump can be manual or automatic. Automatic, of course, is more convenient and reliable - if the pump runs without water, it may fail. Typically, automatic drainage pumps are equipped with a float switch. To control the drain pump, simply set the desired on / off level. The adjustment lever (the same float switch) is kept at the water level. If it goes down, the pump will automatically turn off. If it rises, it turns on. Management of the drainage pump of more complex modification
carried out 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 to look for when choosing a submersible drainage pump.

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

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

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

Application advice

You can avoid blockages and extend the life of the drain 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, during the dry season it can be used for irrigation. You just need to send the collected water to the irrigation system with the help of a pump.

Complete set and additional options. The more accessories that come 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 diverted liquid to go back to the pump (many manufacturers do not include it), a removable suction screen 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 an electric motor cooling system with pumped water.

Availability of technical support. No matter how technically literate the user is, he may need technical support at any time. For users of Grundfos pumps, it is always available. Consultation can be obtained both on the choice of the pump, and on the installation of equipment and its further operation. Any customer request is answered almost instantly and very high quality. For the convenience of users, the “Service 24” program operates: the consumer of Grundfos products calls the hotline (the number is indicated on the warranty card), he is switched to the nearest service center, a service specialist arrives at the client within 24 hours and, if the warranty case , fixes the problem on the spot or changes the pump to another one, and takes the old one in for repair. It is possible that the client himself brings the pump to the service - if it is more convenient for him. In this case, the terms of service are the same. If the case is not guaranteed, 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, snowmelt, heavy rains, rising ground water, breakage of water pipes occurs formation a large number water, which is able to undermine the foundation of buildings, flooding their basements.

To help in such situations, to eliminate flooding, a drainage pump is perfect. With the help of such a pump, it is easy to pump out liquid without much effort, even with a certain degree of contamination.

1 Types of drainage pumps

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

All pumps designed for drainage are divided into:

• superficial;
• submersible.

Surface pumps are installed outside the liquid reservoir, 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 on / off the engine, a float mechanism is brought to the start lever. The float mechanism automatically monitors the change in the level in the pit.

When the set level of effluents changes, the drainage equipment automatically turns on and the liquid is sucked in and discharged outside the tank. Due to its mobility surface pumps can be easily moved to the right place in the event of a malfunction or breakdown.

Submersible pumps are basically the same as surface pumps.

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

To perform the tasks described, a Grundfos drainage pump is suitable, which has proven itself with the best side in the market for similar equipment. Due to the fact that the equipment perfectly copes with its tasks and has excellent quality, there is a high demand for it from the consumer.

1.1 Grundfos Group

Grundfos (Grundfos) - a company that manufactures 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 units of pumping equipment per year.

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

In addition to the manufacture of pumping units, the production capacities of the plants include 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 Bjerringbro Press and Machining Factory. But years passed and the name changed several times, until in 1967 until she got her current name.

The company's resources are currently allow us to be the 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 polluted 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 particles in solid form 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 borehole series.

Grundfos drainage pumps in certain applications successfully perform the following tasks:

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

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

Unit design:

Two compartments of the body: a pump section and a sealed chamber in which an 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 kinds of low budget options, which are intended for use in a non-aggressive environment with clean water are carried out in a plastic case. In the manufacture of the impeller, either technopolymer or stainless steel is used as a material.

A convenient handle is installed on top of each model, which simplifies transportation, a cable can be tied to it to immerse the pump in water. To prevent contamination by large mechanical elements, the pump room is protected by a strainer in front of the suction chamber.

2 Types and description

The characteristics of Grundfos drainage pumps are in many ways superior to those of their competitors, which are used in Everyday life. Basically, this advantage is achieved by the high service life and reliability that Grundfos unilift pumping units have. They are ideal for pumping water from deep wells up to 230 meters deep.

In terms of price range, Grundfos unilift cannot be called ideal for the consumer, as it is high, but this is offset by the high quality of the equipment. Pumping equipment manufactured by Grundfos is divided into several series:

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

SPOs are made from materials that tolerate corrosion and have a long service life. service life. They can be used in specific conditions with high blood pressure thanks to the special design. Able to perform water supply functions in private and country ladies.

Submersible pump SQ is designed for pumping water from mines, wells, which have different neck diameters. Due to the small size, there is no operational problem when working with these pumps. Downhole pumps are centrifugal and submersible. An unplanned transfer of the installation to idling is excluded. This is due to the presence electronic elements protection.

Grundfos pumps drainage SQE have no differences from the previous series. The only difference is the wardrobe Grundfos controls CU 301. With this cabinet you can work with submersible equipment and fully control it, regulate the number of revolutions of the engine and the pressure in the system.
Models from the SP A series (1 x 220V) are designed to supply drinking, sanitary, sea and industrial water in residential buildings irrigation systems from reservoirs or water sources. The proportion of impurities or sand in the transported water should not exceed 50 g/m 3 .

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

Soil waterlogging risk

Before purchasing a suburban area, experts always recommend paying special attention to the hydrogeological characteristics of the soil. The technicians who design Grundfos (Grundfos) electric centrifugal drainage pumps know what a risk waterlogging the ground can be for a garden or vegetable garden.

So, the cause of waterlogging can be the proximity of the lake to the site where the estate, field, meadow lands are located. Under these conditions, Grundfos submersible drainage pumps for pumping dirty water prevent a number of hazards.
