Model range of pumping stations of the German manufacturer
- Fire extinguishing pumping stations are distinguished by high performance and high pressure.
- Grundfos domestic pumping stations are used in private homes. They are compact and quiet.
- Booster pumping stations are used in municipal waterways and in industry. They are called second ascent stations.
Any of the listed series of equipment is presented in various designs that meet specific 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 instructions for servicing the Grundfos pumping station.
Characteristics of Grundfos products
The greatest demand for equipment from a well-known manufacturer is in the world agriculture. Required here pumps for irrigation of land, to increase the pressure in systems located far from water supply sources. The user can choose equipment for irrigation or domestic water supply.
A special feature of grundfos pumping stations is the well-thought-out layout of the units that form a single system. The special steel body reliably protects the 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 by subsidiaries they are produced only for their region, without the right to export.
JP pump series
The JP series represents centrifugal self-priming pumps, which are equipped with the Grundfos JP Booster pumping stations. The pump includes a hydraulic tank with a capacity of 24-60 liters, depending on the capacity. 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 the grundfos JP Basic 3pt pumping stations. The self-priming submersible ejector pump has the best price-performance ratio of all domestic pumps from this company. High capacity, 3.6 cc m / hour, head 47 m water. Art. and a membrane accumulator characterize the demand for equipment. During operation, the pump delivers water saturated with air, without reducing performance. Most often, the pump is used in private backyards.
The Grundfos Hydrojet JP series is extremely robust. The anti-corrosion coating is made from the outside and from the inside. Reliable automation leads the process in an economical mode. With a continuous flow of water, the pump is completely turned off.
The pumps operate at a pressure of 5 or 6 atmospheres in the system. The station is equipped with membrane-type accumulators of various capacities. The grundfos hydroijet jp5 residential pumping station is equipped with a 24 liter tank. But the system, in which a 60 liter hydroaccumulator is installed, keeps the parameters more evenly. 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 accumulator tank is separated by a diaphragm partition. In one part of it there is water, in the other air is supplied under pressure. 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 pump series works with a diaphragm storage tank. The system is pressurized up to 4.5 bar or 45 mWg. Art. Designed for the organization of water supply for 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 pumping station grundfos 3-35, 35 meters of water column, 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, an additional storage tank is used.
Varieties of pumping stations "Grundfos" used in industry
The fire extinguishing station is represented by pressurized water and foam systems. The Grundfos Hydro MX pump type has more than 60 models. Equipment can be selected for different fire extinguishing systems:
- productivity - 1.1- 55 kW, with an automatic starting system;
- productivity - up to 120 cubic meters / hour;
- head - 145 m.
Grundfos pumping stations, capable of delivering foam, are the main tool in fire extinguishing installations. Such systems are expensive, from 882 thousand rubles.
Booster stations from Grundfos Hydro represent a new type of equipment. The stations are used to raise the pressure in the water conduit system. Grundfos Hydro 2000 pumping stations are in demand in public utilities. The station is small-sized, operates in automatic mode, turning on when the pressure in the system decreases. The compact unit has technical characteristics:
- productivity - 600 cubic meters m / hour;
- head - 144 m;
- maximum agent temperature - +700 FROM;
- working pressure - 16 bar.
The pump can be installed in a 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.
Feedback on the work of pumping stations "Gruenfos"
Before buying expensive equipment, you need to look at the reviews, find out the opinions of users. We will present some of them.
Sergey from Ukraine:
I have been using the station since 2013. I am satisfied with the device. The pumping station MQ 3-35 is a necessary thing for giving. The disadvantage is that it does not pump dirty water. Before installing the pump, a new well should be pumped with a less finicky apparatus. You need to put a protective grid on the suction. If the sand clogs the fan, which is installed in the flow sensor, the system will be unregulated. I use it and recommend it to others.
Vladimir Nizhny Novgorod:
Pumping station grundfos JP Basic 3pt, in use for 2 years.
Advantages: high-quality assembly, maintains pressure, maintainable.
Disadvantages; after inactivity for several days, the water in the cast iron housing is rusty.
There are no substantive comments. Used in automatic mode. After a hose burst at the suction, the pump pumped in a lot of air, rattled and the ceramic oil seal fell into disrepair. Put another one, it works.
