Model range of pumping stations of the German manufacturer

Pumping stations used in water systems for domestic and industrial purposes:

Fire extinguishing pumping stations are characterized by high productivity and high pressure.
Grundfos domestic pumping stations are used in private homes. They are compact and quiet in operation.
Booster pumping stations are used in public waterways and in industry. They are called second lift stations.

Any of the listed equipment series is presented in various designs, meets certain tasks. The manufacturer has simplified the installation of equipment as much as possible. An inexperienced summer resident can cope with the installation, guided by the maintenance instructions for the Grundfos pumping station.

Characteristics of Grundfos products

Most demand for equipment well-known manufacturer in the world agriculture. Here they are required for irrigation of land, to increase the pressure in systems located far from water sources. The user can choose equipment for irrigation or domestic water supply.

A feature of grundfos pumping stations is the thoughtful layout of the nodes that form a single system. The case from special steel reliably protects working body. The complex can pump water from open reservoirs, wells and wells. The MQ, JPB series are developed according to the company's technology, but are produced by subsidiaries only for their region, without the right to export.

JP Pump Series

The JP series represents centrifugal self-priming pumps, which are equipped with Grundfos JP Booster pumping stations. Complete with the pump there is a hydraulic tank with a capacity of 24-60 liters, depending on the performance. The best irrigation system is an ejector-type station that supplies water from open reservoirs and pools.

The injection system lifts water from a depth of 25 meters, while the engine is located on the surface, and the lifting mechanism is lowered into the well. At the same time, the system works almost silently.

The most famous of this series of equipment are grundfos JP Basic 3pt pumping stations. Self-priming pump with submersible ejector the best ratio price-quality of all household pumps of this company. High performance, 3.6 cu. m / hour, head 47 m of water. Art. and a membrane accumulator characterize the demand for equipment. During operation, the pump supplies water saturated with air, while not reducing productivity. Most often, the pump is used in private farmsteads.

The Grundfos Hydrojet JP series is extremely rugged. Anti-corrosion coating is made outside and inside. Reliable automation leads the process in an economical mode. With a long flow of water, the pump is completely switched off.

The pumps operate by creating a pressure of 5 or 6 atmospheres in the system. The station is equipped with membrane-type accumulator tanks of various capacities. The grundfos hydroijet jp5 pumping station for residential buildings is equipped with a 24 l tank. But the system keeps the parameters more evenly, in which a hydraulic accumulator with a capacity of 60 liters is installed. With a power of 0.75 kW, the pump has a head of 43 m and costs 13,800 rubles.

MQ pumps

Pumps complete with diaphragm tanks represent a series of stations for domestic use. The battery tank is divided by a membrane partition. Water is in one part of it, air is supplied under pressure in the other. As a result, the pressure in the water system will always be stable, and the pump is less likely to receive a command to turn on. The equipment is produced with and without a hydraulic tank.

The grundfos mq 3-45 series pumps work with a membrane storage tank. The system is pressurized up to 4.5 bar or 45 m of water. Art. It is intended for the organization of water supply of private houses. The device can be used as a booster. Productivity of the device is 3 cubic meters / hour. The system has self-priming from a depth of up to 8 meters. Pump weight 13 kg. The grundfos 3-35 pumping station, 35 meters of water column, also has similar characteristics.

For the operation of these particular pumping stations, pressure drops are critical. The equipment works stably at a voltage of 220-240 V, in other ranges the pump will fail. For the safety of the equipment, it is necessary to use a voltage stabilizer. For rare switching on, an additional storage tank is used.

Varieties of Grundfos pumping stations used in industry

The fire extinguishing station is represented by pressurized water and foam systems. Type of Grundfos pumps Hydro MX has over 60 models. Equipment can be selected for different systems fire fighting:

performance - 1.1-55 kW, s automatic system launch;
productivity - up to 120 cubic meters / hour;
pressure - 145 m.

Pumping stations "Grunfos", capable of supplying foam, are the main tool in fire extinguishing installations. Such systems are expensive, from 882 thousand rubles.

Grundfos Hydro booster stations represent a new type of equipment. Stations serve to raise the pressure in the water supply system. AT public utilities Grundfos Hydro 2000 pumping stations are in demand. The station is small-sized, operates in automatic mode turns on when the pressure in the system is reduced. The compact unit has specifications:

productivity - 600 cubic meters. m / hour;
head - 144 m;
maximum temperature of the agent - +70 0 C;
working pressure - 16 bar.

The pump can be installed in the heating system.

The manufacturer supplies not only surface equipment, but also submersible pumping stations. Their cost is much higher, but the systems are the most reliable in operation.

household stations autonomous water supply for home, summer cottage, farming acquired a strong demand along with the establishment of a competent economic policy in many states.

Today, the maximum amount of land is used for domestic agricultural production. Most countries in the world allocate wide areas to farmland. Under these conditions, the pumping station of the first, second rise becomes a device that is unable to lose its relevance.

The product line of Grundfos pumping stations provides wide opportunities quality irrigation of fields, orchards and orchards . A pneumatic-hydraulic pumping station for automatic water supply for a summer residence, the price of which is attractive to the consumer, is successfully used to increase the level of domestic comfort in private homes .

Design features

Boosting water pumping stations- these are practical devices, all parts of which work harmoniously in unified system. Grundfos authoring - specially treated steel - covers and reliably protects corners and work items different models devices. All devices are ready for installation and are fully adapted not only to various containers but also to wells, wells, reservoirs.

As a rule, the country of origin of an apparatus such as a pumping station for increasing pressure is Germany, but devices are also manufactured in most EU countries using Grundfos technology. Each branch of this corporation studies the needs of its region - based on these data, a plan is made for the release of the next model range.

The scientific approach pays off: in every country chosen for cooperation, Grundfos is always head and shoulders above other manufacturers of devices such as water self-priming pumps and pumping stations.

The catalog of this brand contains devices in which each part is subject to a smooth decrease and increase in pressure. The apparatus consists of several main parts. First of all, these are pumps for fast water supply from depth.

The latter may apply independently . In cases where the liquid lies at a depth of less than eight meters, experts advise the use of centrifugal self-priming pumps (for water, technical or drinking liquids).

More about the process of water lifting

Centrifugal self-priming pumps- The easiest way to get water. They fit perfectly into the water supply system of a private house. All you need to use this device is storage tank installation (it is filled with water for drinking water in the household or for hygienic purposes).

With the help of this device, water is pumped out of small volume tanks. AT storage tank a sensor is installed - it monitors the liquid level and turns off the water-lifting device in a timely manner. Another task of such a sensor is to control the drop in the water level in the tank. If there is not enough liquid, the pump turns on instantly . It is convenient that the entire cycle of work occurs automatically and does not require regulation.

Distinguish ejector pumps and injection. Pumping stations of the ejector type are advised to be located in a technical, not a residential area. The constant discharge of the ejector in these devices is responsible for the absorption of moisture. The Grundfos ejector pumping station has proven itself all over the world as watering mechanism for gardens and orchards - that is why RusNasos offers it to the Russian consumer today.

Injection pumps are distinguished by an increased allowable depth of water - it can reach 25 meters. These units are also suitable for wells small size. Feature these Grundfos tools - autonomy of their components . The engine of injection-type devices is located on solid ground, and the air-discharging mechanism is immersed in water.

Using pumps with diaphragm pressure tanks

German private water supply pumping stations can also be used in combination with membrane pressure tanks. Installing the pump on a membrane tank and equipping its relay is a development of Danish engineers, which has received the definition of a "complete mobile pumping station".

Silent compact pumping station for an apartment, house or cottage membrane tank Grundfos special design. It is a container made of metal, divided in two by a membrane. Both parts of the container are sealed. Air enters the first under pressure, water is pumped into the second.

As soon as the relay detects the achievement of the maximum pressure, the water pumping stations are turned off, and the liquid in the membrane tank can be used . The hydraulic pumping stations are restarted by reaching the lower pressure limit, also reflected on the relay.

Main advantages

Buy a domestic pumping station water supply for a dacha or a private house of a Russian consumer is motivated by numerous advantages. First of all, technicians and users evaluated the stable performance of the pressure generated by these devices. Pumps MQ 3-35, MQ 3-45 and other models are able to maintain this indicator at a level that is optimal for the operation of any water heater, adjusting to its needs.

These devices are also optimal according to other criteria. So, they have a reduced number of starts and stops of the pump - with the help of this technology, the engineers of the Danish corporation have achieved longevity of devices .

Another plus of the units of this brand is the ability of a volumetric membrane tank to accommodate large supply of water . This function provides a constant water resource that can be used during a power outage.

Ask any German to translate the phrase: “Unsurpassed quality, high reliability and super popularity.

Everyone will answer you without hesitation: Grundfos. True, judging by the reviews on the network, many Russian users would have answered the same way. For those who hear about this trademark For the first time, we recommend reading our article.

The reason is reliable, trouble-free operation, complete equipment and the highest performance.

Each model is a set of solutions that completely exclude the participation of the user in the process of supplying the house and the plot with water.

How it works ^

To pump water into the HC water supply network, Grundfos uses self-priming pump surface type with built-in ejector.

The engine is started and stopped by a pressure switch signal, in which the on and off thresholds are configured by the user at his discretion.

To prevent frequent starts of the pump motor in case of short-term use of the water supply system, the system is equipped with an elastic membrane accumulator, the volume of which is selected according to the performance of the station.

In the event that Grundfos seems expensive to you, pay attention to the AquaRobot pumping stations, we wrote an article with reviews, specifications, prices, read it only in our online magazine.

How to choose a pumping station? ^

Grundfos HC should be selected based on the required pressure and performance.

Their maximum values are given in the passport, but they only help to get general impression about the capacity of the equipment.

Much more valuable from a practical point of view are tables or graphs showing what performance the pump will have at a particular pressure.

The required performance is calculated approximately, taking into account the following data: water consumption when using a tap (for a pipeline pressure of 2 atm) is 3-4 l / min, a shower cabin - 10-12 l / min.

The required pressure is measured in meters of water column, it is calculated by summing up three components:

the required pressure in the pipeline (approximately 2 atm or 20 m. w. st);
maximum height of water fittings relative to the pump;
pipeline hydraulic resistance.

To select a station, the last value can be calculated approximately: every 10 m of pipeline is equivalent to one meter of pressure.

This, by the way, should be taken into account when determining the suction depth.

If the surface water in the well is below ground level by 5 m, a the distance from the well to the pump is 20 m(this often happens when installing a pump in a house), then the maximum suction depth for the station must be at least 7 m (5 + 20/10).

When buying a station, check its completeness.

Grundfos pumping stations are equipped with everything you need, but unscrupulous sellers can sometimes remove a filter or check valve to sell them separately.

In this case, the buyer is told that these elements are not included in the NS kit. Many believe, because with the NS of other manufacturers, indeed, this is often the case.

Important: Grundfos pumping stations are very demanding on the quality of power supply. Our electrical networks, as you know, are not yet up to European standards in quality, so it makes sense along with the station, purchase a voltage stabilizer.

Best Selling Models ^

Below we have given a mini-rating of the most popular pumping stations from Grundfos, their cost and main technical characteristics. Purchasing one of these stations, we believe, will be a very reasonable investment, given the reliability of these devices.

Grundfos JP Basic 3/24 ($350) ^

User opinions ^

Alexey T., St. Petersburg

I have a Grundfos MQ 3-45 station in my country house. I will immediately note the advantages: the pump runs very quietly, the start is smooth, without large starting currents. 100% fail-safe hardware. The disadvantages can be attributed to only one thing: for five years of operation, the plastic on the power button burst. She had to use it too often to forcibly turn off the pump during periods of power surges and sags. By the way, everyone potential buyers I recommend taking into account that such fluctuations in the power supply network have a very bad effect on the pump resource, so if your power supply is unreliable, look for a more durable model or connect Grundfos through a stabilizer.

The station is open all year round. For greater convenience, I installed an additional tank of 100 liters. The pump turns on when the pressure drops to 2 bar and turns off as soon as it rises to 4. Performance is enough for several points of water intake, as well as to ensure the work washing machine. Even at the maximum flow rate, there is always enough water. In general, I advise everyone to buy such a thing, despite the high cost. On the own experience convinced that it is fully justified.

Alexander P. Volgograd

Four years ago, I installed a Grundfos automatic pumping station for water supply country house. Works all year round, especially intense in summer due to irrigation. I decided to buy after a long study of the forums on the Web, judging by the reviews, this is the best option for a pumping station. I have never been disappointed in my choice. Sometimes you have to read user complaints, they say, it often fails. Most likely the issue here is poor quality power supply, due to the presence of an electronic controller, Grundfos pumping stations are very sensitive to voltage drops. I immediately connected mine through the stabilizer and I can declare with full responsibility: the equipment works like clockwork.

The station pumps water from a well. The operation of the pump is controlled by pressure and water flow sensors. If the water in the well falls below the intake pipe, the station will automatically turn off.

I especially like the fact that it maintains a constant pressure at any flow rate, and not like in conventional stations: first, the pressure in the tap decreases until the membrane accumulator is empty, and then, when the pump starts, it increases. With Grundfos, everything is different, water flows like a tap in a city apartment.

I would also like to note the low noise level and an absolutely complete package, I didn’t have to buy anything extra at all.

I can’t point out any shortcomings, except that the price bites a little.

Viktor M., Kaluga

First, I installed the Marina automatic pumping station. Pretty good, but when you turn on the pump it makes too much noise, and the floors are shaking right away, it seems that the house is about to fall apart. I sold it to a friend, and in return I bought Grundfos JP. Not heard at all! I installed it in the basement, during the operation of the unit I do not feel any discomfort. The pump is very productive, confidently draws water, despite the great depth of the well and a significant distance to it. I can easily take a shower at the same time as the washing machine is running.

What is a check valve for a pumping station - how to choose, how much does it cost

The history of the Grundfos brand begins with the post-war devastation, when a small repair shop arose in Denmark, which grew into a powerful electrical giant with subsidiaries around the world.
