A, product overview
SPGB type completely without leakage blocking pipeline centrifugal pump series, the company is using Japanese technology, and absorb the shielding pump design and manufacture of professional international advanced technology, digestion and innovation of science and technology personnel, by our company newly launched the second generation of shielding pump product, this product is on the basis of the original improved electromagnetic core technology, improve the state of fluid motion, improve the efficiency by more than 10%, a higher level comprehensive performance index is more, the product is more ideal.
SPGB type shield pump is a pump motor and pump integrated structure products, advanced technology, static seal, no shaft seal, reliable performance is high, be totally without leakage, because of its low noise motor itself, together with shielding pump low failure rate, safe environmental protection, and the best maintenance cost advantages, such as wins the general customers, high quality for the Chinese market at the same time enhance the demand of the water pump.
Products are widely used in petrochemical, chemical industry, medicine, textile, nuclear power, military industry, shipbuilding and urban water supply and drainage, fire fighting pump, pressurized water supply in high-rise building, garden sprinkler irrigation, cold and hot water circulation pressurization in hvac refrigeration, etc.Particularly high requirements for vibration and noise, such as key project, pump room, central air conditioning and academy, and so on.Can also be used to transport pressure and does not produce crystallization and solidification temperature of the liquid.Especially harmful to the human body and the environment and unsafe liquid or liquid and so on. 
SPGB type pump can also play an important role on more projects, has also been the praise of users.  
Second, the product features
 
Type 1, SPGB shielding pump for can guarantee no leakage, it can transport to the human body and environment, harmful volatile and expensive equipment leakage of liquid. 
2, not to inhale air, suitable for vacuum system and metamorphic fluid conveying is exposed to air. 
3, without oil seal design, can reliably conveying pump is difficult to transport of high temperature, high pressure, low temperature and the change of temperature and pressure of liquid. 
4, bearing using conveying fluid lubrication by oneself, do not need lubricating oil, so no pollution conveying liquid, and dispense with the trouble that oil on a regular basis. 
5, the structure of the pump is reasonable, the motor and pump coaxial, small volume, light weight, cover an area of an area small, stable operation, easy installation, no need to adjust, convenient maintenance, do not need to adjust, easy maintenance. 
6, impeller adopts water thrust balance type design, make the rotor can be in the running in the suspension design, reduces the axial wear of graphite bearing, so as to improve the service life and reduce the operation cost. 
7 no cold to fan, motor, so the running noise and vibration is very small. 
8, pump import and export of the specifications of the flange design and standard valves are the same, and in the same center line, the center is low, easy to pipeline layout, pump room design is also reasonable and practical. 
9, the standardization of parts, high degree of serialization. 
10, junction box adopts waterproof structure, can be used in outdoor security. 
11, according to the requirement, that is, the flow and head of the pump series, in parallel operation mode. 
12, new USES of graphite bearing, high wear resistance, low friction coefficient, not aging, silt, etc.  
Three, use the product
 
Type 1, SPGB shielding pump can transport clean water and physical and chemical properties similar to other liquid Yu Qingshui, suitable medium temperature - 30 ℃ to + 90 ℃.Particularly applicable to industrial and urban water supply and drainage, fire pressurization, high-rise building construction pressurized water, garden sprinkler irrigation, long-distance transmission of hvac refrigeration cycle, cold and hot water circulation pressurization in the bathroom, etc, and form a complete set of equipment. 
Type 2, SPGR heat shielding pump occasions for the medium temperature is higher, suitable for medium temperature 100 ℃ to 380 ℃.Mainly applied to energy, metallurgy, chemical industry, textile, paper making, textile and hotel, restaurant, bathroom etc. 
3, SPGT anti-corrosion type pump can transport not containing solid particles, suitable for petrochemical, chemical, metallurgy, electric power, papermaking, food, pharmaceutical research institutions and synthetic fibre and other departments. 
4, the circle of SPGN inverse shielding pump for conveying liquid gas, liquefied petroleum gas medium.  
Fourth, working conditions
 
1, medium must be soft water, thin, solidify, nonflammable, fluid containing no solid particles and fibers. 
Type 2, SPG pump medium temperature not to exceed 90 degrees, SPGR type pump medium temperature not to exceed 380 degrees. 
3, general system working pressure is less than 1.2 mpa, inlet pressure not less than 0.05 mpa, special occasions you should contact with the company in advance. 
4, the highest pressure 1.6 MPa SPG shielding pump system, namely the pump suction + pump ≦ 1.6 MPa
