Axial flow pump will be flammable

Submersible axial pump submersible pump running in the water, the cooling results are better, pump and electromechanical transmission from the high, the pump seat assembly from other types of pumps slightly higher, can be throttle, compared to single vertical vertical Pump drive shaft is longer, power consumption slightly larger than the submersible pump. Oil spill asylum and other active asylum effect, but once a huge change, only the submersible pump back to the factory for training, the pump running for a lot of inconvenience.
     Axial flow Pump Pump that carry flammable, explosive, toxic or valuable media, require a shaft seal to withstand or adopt a non-exposed pump, such as a magnetically driven pump, a diaphragm pump, a barrier pump, a gear pump, and a chemical pump power at 200kw The cost of the pump is about 15 to 1.8 times that of the conventional pump, and the cost of the above-mentioned pump is around 200kW. Submersible pump electromechanical request to prevent mechanical and electrical leakage of external water and other asylum. Single-shaft vertical axial pump to adopt ordinary electromechanical, in the electrical and shelter in fact do not need special shelter.
