The SPG series fully leak free shielded pipeline centrifugal pump is a second-generation shielded pump newly launched by our company, which adopts Japanese technology and absorbs advanced design and manufacturing technology from international shielded pumps. After digestion and innovation by our technical personnel, this product improves the electromagnetic core technology on the original basis, improves the fluid motion state, and increases efficiency by more than 10%. The comprehensive performance indicators have reached a higher level, and the product is also more ideal
SPG shielded pump is a pump product with an integrated structure of electric motor and water pump. It has advanced technology, static sealing, no shaft seal, high reliability, and completely leak free performance. Due to its low motor noise, low failure rate of shielded pump, safety and environmental protection, and optimal maintenance cost, it has won the welcome of many users and also enhanced the demand for high-quality water pumps in the Chinese market
The product is widely used in the petrochemical, chemical, pharmaceutical, textile, nuclear power, military, shipbuilding and urban water supply and drainage, fire booster pumps, high-rise building booster water supply, garden sprinkler irrigation, HVAC refrigeration and other cold and warm water circulation booster applications. Especially in places with high requirements for vibration and noise, such as key projects, pump rooms, central air conditioning, and research institutes. It can also be used to transport liquids that do not crystallize or solidify under pressure and temperature. Especially harmful and unsafe liquids or valuable liquids that are harmful to the human body and the environment.
The SPG type shielded pump can also play an important role in more projects and has received unanimous praise from users. |
1. SPG shielded pumps can transport liquids that are harmful to human health, the environment, and equipment, as well as expensive and prone to leakage, due to their ability to ensure complete non leakage.
2. Not capable of inhaling air, suitable for vacuum systems and conveying liquids that deteriorate upon contact with air.
3. The oil-free design can reliably transport liquids with high temperature, high pressure, low temperature, and temperature and pressure changes that are difficult for general pumps to transport.
4. Bearings use the conveyed liquid for self lubrication, without the need for lubricating oil, so they do not contaminate the conveyed liquid and eliminate the trouble of regular oil injection.
5. The pump structure is reasonable, with the motor and pump coaxial, small volume, light weight, small footprint, smooth operation, easy installation, no need for adjustment, easy maintenance, no need for adjustment, and easy maintenance.
6. The impeller adopts a water thrust balance design, which allows the rotor to be in a suspended state during operation, reducing the axial wear of graphite bearings, thereby improving their service life and reducing operating costs.
7. The motor has no cooling fan, so the operating noise and vibration are very small.
8. The specification design of the pump inlet and outlet flanges is the same as that of standard valves, and they are located on the same centerline with a low center, which is convenient for pipeline layout. The pump room design is also reasonable and practical.
9. The standardization and serialization of components are high.
10. The junction box adopts a waterproof structure and can be safely used outdoors.
11. Pumps can be operated in series or parallel according to usage requirements, such as flow rate and head.
12. The newly adopted graphite bearings have the advantages of high wear resistance, low friction coefficient, anti-aging, and resistance to sediment and sand. |
1. SPG shielded pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water, suitable for medium temperatures of -30 ℃+90 ℃. Specially suitable for industrial and urban water supply and drainage, fire pressure boosting, high-rise building pressure boosting water, garden sprinkler irrigation, long-distance transportation HVAC refrigeration cycle, bathroom and other cold and warm water circulation pressure boosting and equipment matching.
2. SPGR high-temperature shielded pump is suitable for conveying medium at high temperatures, ranging from 100 ℃ to 380 ℃. Mainly suitable for energy, metallurgy, chemical, textile, papermaking, textile and hotel, restaurant, bathroom and other departments.
3. SPGT anti-corrosion shielded pump is used for conveying solid particles free materials and is suitable for petrochemical, chemical, metallurgical, power, papermaking, food, pharmaceutical research institutions, and synthetic fiber departments.
4. SPGN reverse circulation shielded pump is used for transporting liquefied gas and its medium. |
|
1. The medium must be soft water, thin, non solidifying, non flammable, and a fluid that does not contain solid particles or fibers.
2. The medium temperature of SPG pump shall not exceed 90 degrees, and the medium temperature of SPGR pump shall not exceed 380 degrees.
3. In general, the working pressure of the system does not exceed 1. 2MPa, import pressure not less than 0.05MPa, special occasions should contact our company in advance.
4. The maximum pressure of the SPG shielded pump system is 1.6MPa, which means that the suction pressure of the water pump plus the pump head is ≤ 1.6MPa
