优势（Advantages）：
1. The machine has high sealing performance, and each conductor core is individually insulated, tinned and embedded with resin, so it will not be affected even if the cable sheath and core insulation are damaged.
2. The motor is optimized according to the working mode S1, thermal resistance class F, and explosion-proof type "ATEX T4, FM/CSA Ex Class I, Division 1, Groups C & D, T4", which can ensure high operating reliability
3. The shaft is made of corrosion-resistant stainless steel and has a long service life
4. The bearings are sealed at both ends, lubricated for life, have a long service life, are maintenance-free, and are suitable for continuous operation
5. The mechanical seal (liquid seal) is lubricated with environmentally friendly, non-toxic, food-grade lubricants
6. Energy saving is achieved through optimized hydraulic system and high efficiency
7. The use of optimized cutting mechanism (S impeller) is trouble-free and will not clog
8. There is no risk of leakage in the direct-coupled pump (the volute of the pump is cast as one piece with the motor housing)
9. When fixedly installed, easy installation and disassembly are ensured by automatic screwless connection, and leakage is prevented by elastic seals
10. The hexagon socket bolts in contact with the medium are all made of stainless steel and can be easily disassembled after many years of use, so it is easy to maintain
11. With 2 A mechanical seal that is independent of the direction of rotation provides double safety and uses an environmentally friendly oil seal. For abrasive and corrosive liquids, a mechanical seal with a shielded spring can be used. All specifications are modular in design, so only one set of spare parts is required.
