Technical characteristics of Grundfos pumps

Grundfos pumps

Grundfos company specializes in the production of pump motors and components. The beginning of production activity was laid in 1945. During this time, the company expanded its production capacity by opening new representative offices in several countries of the world. The number of products produced per year exceeds 15 million units.

The number of employees is 18,000 people. The company pays special attention to the qualifications of workers, on which the image of the company and the high quality of pumping equipment depend. Working conditions and social guarantees provide high professional dedication.

The tireless work on improving technology and modernization puts production among European leaders. One of the latest innovative achievements is the production of pumping units with significantly lower energy consumption.

Application area:

• in domestic heating systems and for hot water supply;
• for water disposal;

• for pumping contaminated water;
• with dosing fluid in industrial technology;
• in the air conditioning system;
• to increase pressure in water systems;
• to lower the groundwater level.

The principle of operation of hydraulic units is to rise from the depths and pump fluid in the system by converting energies - mechanical to moving. Especially popular was the use of Grundfos pumps for heating systems of cottages having 2-3 floors.

The motor ability of the device makes coolant distributed according to a complex branching pattern dynamically and evenly. Heating costs are reduced due to the rational use of heat and the economical characteristics of pumping equipment.

Pump range

A wide range of pump applications divides products into types for convenient selection. The entire range has European production quality, good performance, minimum maintenance requirements, and guarantees perfect operation.

Multifunctional equipment:

• Circulation pumps are installed for heating equipment. The compact look and silent operation ensure the movement of water through the pipes of the heating and water supply systems.
• Surface units are capable of lifting water from wells and wells up to 10 meters deep without diving. They have been widely used both in everyday life and in agriculture for watering fields.
• Drainage pumps are used when pumping water from various reservoirs: pits, pools, wells, etc.
• Pumping stations supply water from reservoirs with a depth not exceeding 8 meters. The station is equipped with a tank pressure monitoring system, which does not require regular monitoring during operation.
• Well pumps provide water from the ground. By installing this equipment, you can reduce the cost of additional parts when drilling wells. Models are made of anti-corrosion materials, have a multifunctional protection system.

Equipment for a specific purpose:

• For the wells.
• Sewer.
• Centrifugal.
• Self-absorbing.
• Dosage
• To increase pressure.
• Cantilever.

The product range is complemented by accessories for all types of pumps.

Advantages of Grundfos products:

• versatile scope;
• multifunctionality of some models;
• have resistance to heavy loads;
• when working do not make a lot of noise;
• have energy-saving qualities;
• quite a long service life;
• the equipment has a simple design;
• details of the mechanism are resistant to abrasive wear;
• the presence of an automatic control unit in almost all models.

Over many years of use, Grundfos pumps have gained consumer confidence through their trouble-free operation. Millions of people all over the world were able to verify the reliability of the equipment. Certified products meet stringent quality standards.

Grundfos products cannot be characterized in general terms. The image of the company is high quality. Therefore, claims are rare and they all have a logical explanation:

• The insufficient efficiency of circulation models limits their use in the domestic sphere.
• Installation should be done only by a specialist. Incorrect installation can lead to a number of malfunctions.
• The small dimensions of the hydraulic tank make the mechanism more often switch the on / off mode.

Pump design features

• Automatically creates pressure in the system, and regulates power.
• Some pumps include an air valve. This device releases air from the system, the accumulation of which can lead to the formation of plugs.
• There are two ways to connect pumping equipment, depending on the type of model: flanged or threaded. This makes it possible to connect to a pipe of any kind.
• No need for periodic maintenance. This is due to the lack of packing in the kit.
• The starter is reliably protected from moisture by a partition and a wet rotor.
• Sewer models are distinguished by an increased inlet and the ability to pump high viscosity liquids.

The design of the pump consists of a single technical unit, containing:

• electric motor;
• pumping unit;
• electronic control unit.

All structural details are clearly adjacent to each other, forming a single mechanism.

Specifications

Circulation equipment of almost all models is labeled Class A, which means economical energy consumption. Ceramic bearings provide a long service life. The sound of a working device is almost inaudible. Thermal relay integrated in the housing:

• The temperature sensor displays the operating temperature in the range from -10 ° C to +120 ° C.
• The permissible temperature limit of the pumped liquid is from + 2 ° C to +110 ° C.
• Environment - up to +60 ° С.
• The fluid should be inviscid and non-aggressive.
• The operating pressure in the system is from 0.049 bar to 1.08 bar.
• The electric motor works with a power of 0.37 - 355 kW.
• The generated head is from 2 m to 160 m.
• Consumption from 2 to 2000 m 3 hours.
• Power consumption from 55 watts to 270 watts.
• The weight of the device is from 2.4 kg to 6.5 kg.

Grundfos pumps must be used in dry, ventilated rooms, to ensure their protection against moisture and freezing.

Downhole equipment can supply not only drinking, but thermal and mineral water. The choice of model depends on the depth of the well, the diameter and composition of the fluid. Stainless steel with the addition of chromium and nickel makes the pump casing highly durable and protected against corrosion.

Among the advantages from similar devices from other manufacturers, the following qualities stand out:

• the possibility of vertical and horizontal installation;
• high efficiency;
• the electric motor is protected by a control cabinet;
• the cable is coated with a Teflon insulating sheath.

Technical description:

• created head reaches 660 m;
• the range of water supply is from 0.1 to 280 m3 hour;
• voltage 220V - 240V in a single-phase version, up to 400V in three-phase models;
• power from 0.37 to 220 kW;
• have resistance to voltage drops from +6 to -10 percent of the norm.

The main parameters of the equipment are:

• the amount of water displaced over time;
• ability to adjust pressure to increase pressure;
• efficiency;
• deep lifting ability;
• power consumption indicator.

The cost of equipment Grundfos directly depends on the type of model, and the functionality of the mechanism. Technical filler ensures the execution of the work assigned to it.

Prices for some models are:

• circulating: UPS32-120F - 32 342 rubles, UPS 25-40 130 - 8 101 rubles;
• sewage pump Sololift2 D-2 - 25 697 p.;
• for water supply MQ, Grundfos - 27 528 rubles;
• drainage Unilift AP 35/50 - 39 902 p.

In order to correctly select the necessary equipment, you need to familiarize yourself with the description of the characteristics. Of the large number of products offered, you can purchase exactly the model that will fully comply with the requirements for the purpose. And the cost will not include unclaimed features.
