The submersible pump for well use is an improvement on the traditional multi-stage pump, which has obvious uniqueness as follows:
1. High efficiency - capable of continuously running without faults for 8000 hours, which increases work efficiency and also reduces maintenance costs.
2. Electricity saving - Compared to previous traditional multi-stage pumps, this type of submersible pump for well use can save up to 3%-14% electricity, which greatly saves users' costs.
3. Unbalanced device - This is a clear characteristic of self balancing compared to traditional multi-stage pumps. Due to the absence of a balancing device, which means that there is no friction loss or balanced reflux loss in the circular disc without a balancing disc, the pump efficiency of this product is increased by 5-14% compared to multi-stage pumps of the same category. At the same time, it completely solves various faults such as wear or rotor seizure caused by the failure of the balancing device, greatly extending the service life of the pump.
4. When the submersible pump for well use uses a containerized mechanical seal, there is no axial movement, which completely overcomes the failure of the dynamic and static ring grinding surface of the mechanical seal due to poor contact during the axial movement of the old multi-stage pump. In actual operation, it has achieved no leakage.
