Grundfos drainage pumps: product range

Grundfos (Grundfos) occupies a special place on the market of drainage pumping equipment. Danish brand offers a huge range of products. Models belong to a high price segment. Despite this, the product is in demand and remains in demand.

The first thing experts and ordinary customers point out is the highest quality of each product. It is achieved thanks to the experience of professionals, precise control of production and the use of carefully selected raw materials. Drainage pumps from the company are represented in a rich assortment, which is constantly updated.

All goods manufactured in Denmark are divided into separate segments.

• Products for dirty water. This type is designed for pumping liquids with solid debris larger than 10 millimeters in size.

• Pumps for lightly soiled or clean water. Models cope with garbage from 5 to 10 millimeters.

In the segment of submersible pumps reduce the sewer and well model series. This product has an individual scope of use.

To the selected unit to fully cope with the task, it is necessary to consider the scope of each specific model. Products in the catalog of the Grundfos brand are used for a number of tasks:

• organization of water supply systems;

• design of watering system;

• the process of pumping water from reservoirs, pools, flooded premises (basements), pit.

In the case of the organization of an irrigation system, any container (barrel, bucket, etc.) can act as a source. You can also use a well or any waterway. The use of the pump manufacturer is important for country houses. Models are actively used in the construction and industrial sector.

Despite the fact that most of the company's products can not be called cheap, there are several budget options in the range. Cases of such models are made of plastic. Despite the fact that the material is inferior in strength to the metal, it is hard and durable.

For convenient use and transportation, the pumps are equipped with a special handle. To dive under the water, you can attach a cable. When creating the impeller, the manufacturer uses stainless steel or wear-resistant technopolymer. The pump can pump water with a maximum temperature of up to 40 degrees Celsius above zero. In certain cases, this indicator rises to 50 degrees with a plus sign.

Among the rich product range at the peak of popularity is the Unilift KP series. This section consists of about a dozen models. The units have been designed to handle lightly polluted or clean water. The main sphere of use is household. The size of solids in a liquid should not exceed one centimeter in diameter.

For designation of features of a design and operation of each product of this model range the marking is used.

• M1 - sediment without float switch;

• A1 - units equipped with a float switch;

• AV1 - models with vertical float switches.

The range of technical characteristics of Grundfos submersible models included in this segment:

• the highest head: 5.5-7.5-9 m;

• power: 0.3-0.5-0.7 kW;

• weight: 6-8 kilograms;

• power cable: 10 meters;

• efficiency: 8.5-11.5-14 "cubes" per hour;

• output size: 32 millimeters (diameter);

• the impeller and the case of the models are made of stainless steel.

This series is similar to the previous one in terms of technical characteristics. All models that belong to this group are capable of pumping water without interruption with a maximum temperature of 50 degrees Celsius. In the development of the CC series, manufacturers have improved the casing design.

A feature of the models of the above series is the installation of a check valve. Due to the arrangement of the cooling jacket, the unit can work without interruption much more than the products of the Unilift KP series:

• advanced sealing system;

• protection against dry running;

• added a special valve that helps to clean the air in the working compartment;

• sealed power cable entry;

• All products of the series have a universal adapter, due to which you can create a reliable connection with various pipe diameters;

• the length of operation of the float switch can be adjusted without problems, indicating to what level of liquid the pump will operate.

Models have the following operational parameters:

• head: 5-7.5-9.5 meters;

• unit weight: 4.6-5 kilograms;

• Productivity (cubic meters per hour): 6-10-14.5;

• efficiency: 0.25-0.38-0.78 kW;

• in the manufacture of the impeller and the body is used technopolymer.

If you are looking for a powerful and efficient unit for working with dirty water, pay attention to the Unilift AP series. Danish brand offers customers an extensive selection of models. Each pump is equipped with all the necessary protection elements for productive and durable system operation.

At production of the case and impellers of pumps of this series wear-resistant stainless steel is used. The highest temperature index at which the unit can perform all the necessary functions is 55 degrees Celsius. Despite this characteristic, manufacturers advise the use of pumps at lower temperatures to extend the life of the machine.

In the names of the pumps used digital marking. The number indicates the maximum size of solids in water. If the model is marked “12”, this means that the pump can work in water with particles of pollution up to 12 millimeters. Also used markings "35" and "50".

If the letter “A” is used for marking, the model is equipped with a float switch. This item may also have a different configuration. The number next to the letter indicates a single or three phase designation, denoted by the corresponding numbers "1" and "3".

Characteristics of AP series models:

• maximum weight of the model: up to 15 kilograms;

• performance: up to 35 cubic meters;

• head: up to 18 meters;

• Efficiency: 0.7 to 2.15 kW.

The main area of ​​use of this model range is industrial.For domestic purposes, products are practically not used. Cast iron is used for the manufacture of aggregates, as a result of which the models add significant weight. The material also influenced the total cost of each unit.

Manufacturers have worked not only on the body, but also on the performance of the pumps. Models of the DP series can be safely used not only in dirty water, but also in liquids whose pH is from 4 to 10 pH. The size of solid particles should not exceed one centimeter in diameter. The maximum water temperature is 40 degrees Celsius, but for a short period it is possible to increase this indicator. Even if dirt particles have abrasive properties, they will not adversely affect the operation of the system.

When designating models, the company uses special markings:

• Ex - housing with explosion-proof property;

• E - equipment level sensor;

• A - float switch;

• AT - smooth operation with a maximum particle size (10 millimeters);

• WITH - exit with a diameter of 50 or 65 mm.

Technical indicators of the DP series:

• maximum power: up to 3.5 kW;

• head: 13.5-20.1-25 meters;

• weight: up to 61 kilograms;

• efficiency (“cubes” per hour): 48.

The model range of EF pumps has almost the same parameters as products from the DP series. The only difference is the size of solids in water. Units from the EF segment without problems pass elements with a diameter up to 30 millimeters. Also, the products have reduced power - up to 2.2 kW.

In terms of performance and design, there are no differences. Models from this series are labeled in the same way as in the DP series.

This is the second selection of industrial pumps. Units are designed for pumping water with solid elements, the dimensions of which range from 10 to 20 millimeters in diameter. The use of devices in a liquid with a temperature of 40 degrees Celsius above zero is permitted.

The main difference between the products of this series is the increased size of the outlet: 50, 80, 100 or 150 millimeters. The joint is designed by means of a flange.

Operational parameters:

• highest efficiency rate: up to 155 cubic meters per hour;

• head: up to 51 meters;

• performance: from 0.75 to 22 kW.

They can be straight and denoted as “0D”, or they can be of the star-delta type with a “1D” sign.

This section includes powerful and efficient submersible pumps. Parts of the units are made of cast iron. When designing the wizard, they installed a strainer on the suction line, as well as a pressure port at the top of the product and on the side.

Spheres of use of DWK models:

• work on the land;

• building;

• fishing;

• arrangement of tunnels;

• drainage wells.

Performance characteristics:

• maximum head: 102 meters;

• water temperature: up to 40 degrees Celsius;

• highest feed rate: up to 432 m3 / h;

• Series sediments are recommended for use in high pressure conditions.
