1. The centrifugal pump adopts rear pull structure, there is no need to disassemble the pump during maintenance, this structure is also lightweight, so it is easy to replace the spare parts.
2. Due to the separate design for the bearing and the mechanical seal, the bearing can keep in its original position even when the mechanical seal leaks or needs replacement. This provides the bearing with an extended service life, and ensures less maintenance of the pump.
3. Our centrifugal pump can be used as self-priming pump, when it is equipped with the self-priming device, that can greatly reduce the cost and service power, speed up the self-priming time, at the same it can support dry start.
4. With high working efficiency, takes DA250/40 pump as an example, the maximum efficiency reaches 88%, that can greatly reduce the power consumption and cost, it is energy saving and environmental protection.
