In any case, you have to disassemble the pump and remove the shaft obstruction. The special design of hydraulic parts with advanced impeller pumps Grundfos company, allowed not only to once and for all get rid of this problem, but also to ensure greater protection of the impeller from the effects of friction particles in suspension and shock loads. In addition, these pumps are used alloy impellers made of different materials, which when exposed to shocks are more reliable than welded.
The presence of such features as double mechanical shaft seal in oil-filled chamber and the oil-filled Grundfos 15-58 pump rotor, cooling pump ensures even when dipping it into liquid in less than half.
A distinctive feature of the Grundfos 15-42 pumps is the presence of grinding mechanism on the input. These pumps are specifically designed for pumping plumbing and liquids containing long fibrous particles. They are able to grind all the suspended inclusions, such as hair, tissue, pulp, down to individual pieces of plastic and wood, in a gelatinous mass. Yet they have higher pressure head characteristics, since they can use smaller diameter plumbing pipeline without any danger of clogging.
On these design features can be said for quite some time. Unfortunately, many sellers, in addition to data listed on the label of the pump (which is mainly flow, pressure and power), they do not know such technical subtleties and distinctive features of some pumps from others.
Overabundance of pumping equipment on the USA market, a wide range of cheap pumps, sometimes does not even have an elementary thermal protection, are pushing to buy a cheap pump. And in a short amount of time you are experiencing problems with repairs and service. It takes time, money, and who knows how long this pump will run until the next repair. Much calmer, pay once more, to get buy really high quality and reliability.

Pump rotor connection to the network
To connect to a network of Taco penciled him a wire or cable is cut and attached to the ends of the excretory or terminal screws in the inlet box. Some types of pump rotors have the box for fixing and commissioning of cables, steel pipes, metal hoses and other cable carve and finish steel pipes, flexible metal hose, etc., outside input boxes can not, because the ends of wires or cables in this case will be protected and can be damaged. Explosion-proof Taco pump rotors are connected to the network by entering into a box of wire and cable cross-section of 25 mm2 with a rubber or paper insulation.
If you connect a cable, whose cross section greater than 25 mm2, in front of the pump rotor install a special adapter box, which operates cable preparation. Wires and cables with a single-current-carrying conductors attached to the terminal screws of the Grundfos pump rotor directly to the inlet box (using bent at the end of the vein rings), and the wires and cables with stranded conductors supplying tips, fixed on the veins pressing or soldering. Tip and ring wear on the screws, opening the box and tighten the two nuts and washers, making sure the reliability of mounting screws and contact the correct jumper settings, connecting pump rotor windings in a star or triangle, depending on the rated voltage of the pump rotor and the network. Then the inlet box closed with a lid or cover to avoid accidental touching of naked, although isolated, conductors, and also keep water and foreign objects on them.

Specialty pumps Grundfos
Grundfos Pump Systems are used in various technological processes in various areas of human life. Different series of equipment Grundfos qualitatively carry out their work in a given application. Among the systems the company Grundfos distinguish industrial and household pumps, perform the tasks. Circulating pumps, including automatic and fully automatic, designed for continuous circulation of water in heating systems and industrial installations for single and two-wire systems with variable supply, for heating systems installed under the floor and to perform other work.
Pumping equipment Grundfos Hilge certified to the strictest standards of industries requiring sterile, so Grundfos pumps used in the food industry, water treatment, pharmaceuticals. Different models of food Grundfos pumps can be used in the manufacture of soft drinks and beer production, the production of dairy products and in other areas.
Food pumps Grundfos Hilge series Contra, Euro-Hygia, Maxa, Maxana, Sipla, Durietta, Domina designed for pumping liquids such as milk, kefir, yogurt and yeast mixtures, serum, and also to work with the wort, alcohol, vodka.
Pumps Grundfos Sololift + can fit a shower, sink, toilet, washing machine or dishwasher at any level of home - from the cellar to the attic, without costly pipelines.
It is now widely used dosing equipment Grundfos Series 400 - Polydos 412, TD 423, Polydos 460, Polydos 440. These modern systems are compact, economical and environmentally friendly. They are characterized by a wide range of flow - from 1000 to 12000 liters per hour, to work with dry and liquid materials of various kinds, ease of use. In a rich assortment Grundfos You can find dosing systems, which can be used for safe and accurate dosing and monitoring of substances such as chlorine gas, ammonia, sulfur dioxide and carbon dioxide.
Is made of steel, high pump Grundfos CR is able to operate smoothly for a long time in seawater.
Pump Grundfos CRT is fully made of titanium, which allows this system to work in salt water for decades without noticeable damage that would inevitably cause any hostile environment.
Grundfos Pumps Series CRT or NKS used for pumping chemically aggressive - explosive fluids, such as diesel fuel and other petroleum products.
Some types of pumps Grundfos, Grundfos ALPHA + example of a series of circulating pump, saving up to 60% of electricity, thanks to a special design, which automatically detects the speed of the pump depending on the needs of the system in heating or hot water, and pumps Grundfos CR provide efficiency exceeding 80 %.
Grundfos - it is also highly efficient equipment for disinfection of drinking water, and biological treatment of industrial wastewater.
Industrial development Grundfos used in oil and gas industry.
Pump Systems Series CR - a vertical multistage centrifugal type (in line), which are used for water, increasing pressure for various technological processes at the facilities of oil and gas industry. Through the use of modern technologies of energy saving, efficiency of pumping systems up to 81%.
A wide range of products Grundfos includes console, dosing pumps, pumping stations for water gardens, vegetable gardens and places for recreation and country houses, set to increase pressure, surface and submersible pumps used in wastewater, sewage, drainage, as well as accessories and for these and other pumping systems. Properly selected pumping equipment Grundfos different series - this is quality work in any field of industry.
If you have a problem to be solved by pumping systems - go to the experts, and will help you choose the right equipment Grundfos, which is completely solve all the problems, based on the individual characteristics of your production and personal management.
