1. Summarize
The SPG series is no leaking shield pipeline centrifugal pumps. Learning from Japan and international shield technique and improve the electromagnetism technique, the efficiency has advanced more than 10%. SPG type shielding pump is a motor and pump integrated structure of pump products. It has the merits of advanced technology, static seal, no shaft seal (Sealing), and high reliability, therefore it is no leakage. because of their low self-electric noise, secure environment, and best maintenance costs, etc. to win the overwhelming majority of users, but also to enhance the Chinese market requirements of high-quality pump.
Especially for vibration and noise requirements of high places, such as key projects, pumping stations, central air-conditioning and scientific research institutions, hospitals and so on. It can be used for transporting pressure and temperature which do not produce crystallization and solidification of the liquid. In particular, unsafe precious liquid which will do harm to human body and a environment.

2. Usage
It is widely used in petroleum, chemical, metallurgical, power, papermaking, pharmaceutical and city drain, water pressurized high-rise buildings, garden sprinkler, fire booster, long-distance transmission, HVAC refrigeration cycle, bathroom, etc. and well-being of the cycle of pressurization equipment, It is most suitable for the life water, fire water and air conditional refrigerator.

3. Characteristic
The electricity machine is cooled by the pump self-cycle water instead of fan. It assured the good cooling effect, low noise, long life span. it is compact, occupy less space. The medium temperature: -30℃~+90℃ for clean hot & cold water. The flux: 3-460 m3/h the outlet pressure: 5～125m.
