 Structural Characteristics and Opreational Principle of Deep Well Submersible Pump:

 Deep well submersible pump is an efficient and energy-saving water lifting tool for submersible work. The motor is filled with clean water to cool the motor and lubricate the bearings. Polyethylene insulated nylon sheath is used in motor winding, water-resistant electromagnetic wire is used, sand-throwing ring and skeleton oil seal are used in the upper part of the motor to seal, so as to prevent leakage of internal and external media of the motor. The water pump is a vertical single-stage, multi-stage centrifugal closed impeller, and the guide shell conveys liquid.

 Difference Between Cast Iron and Stainless Steel Submersible Pump:

 1. In terms of performance, the performance of cast iron deep-well submersible pump is the same as that of stainless steel deep-well submersible pump. The difference is that the extraction medium is different. Stainless steel deep well submersible pumps can be well used in applications with corrosive media, such as seafood factories or seawater, including SS304 SS316 SS316L Duplex stainless steel and super stainless steel and SS904L.

2. In terms of price, cast iron deep well submersible pump has the greatest advantage. Because the greatest advantage of non embroidered steel deep well submersible pump is the application of saltwater, seawater or seafood factories, seawater desalination,offshore,jack-up, floating dock,shipyard. Resisitant corrosive.
