1. Compact structure and small footprint. Because the submersible sewage pump works under submerged liquid, it can be directly installed in the sewage tank. There is no need to build a special pump room to install the pump and the machine, which can save a lot of land and infrastructure costs. The square head Bolt has a large size, which is convenient to use a wrench or use other parts to prevent rotation. Mainly used for rough structural surface and parts with T-shaped groove.

2. Easy to install and maintain. The small sewage pump can be installed freely. The large sewage pump is usually equipped with an automatic coupling device for automatic installation, which is quite convenient for installation and maintenance.
3. Continuous operation long time. The sewage pump is coaxial with the pump and the motor, the shaft is short, and the rotating parts are light in weight. Therefore, the load (radial) on the bearing is relatively small, and the service life is much longer than that of the general pump.
4. There are no problems such as cavitation damage and irrigation water. In particular, the latter point brings great convenience to the operator.
