Submersible sewage pumps have received increasing attention from people. They have evolved from simply transporting clean water to being able to transport various types of domestic sewage, industrial wastewater, construction site drainage, liquid feed, and more. It plays a very important role in various industries such as municipal engineering, industry, hospitals, construction, restaurants, and water conservancy construction. Compared with general horizontal or vertical sewage pumps, submersible sewage pumps have the following advantages:
1. Compact structure and small footprint. Submersible sewage pumps can be directly installed in sewage tanks due to their underwater operation, without the need to build specialized pump rooms for installing pumps and machines, which can save a lot of land and infrastructure costs.
2. Easy installation and maintenance. Small submersible sewage pumps can be freely installed, while large submersible sewage pumps are generally equipped with automatic coupling devices for automatic installation, making installation and maintenance quite convenient.
3. Long continuous operation time. Due to the coaxial design of the pump and motor, the shaft is short, and the weight of the rotating components is light, the radial load on the bearings of the submersible sewage pump is relatively small, and the service life is much longer than that of a general pump.
4. There are no issues such as cavitation damage or water injection. Especially the latter point has brought great convenience to the operators.
5. Low vibration noise, low motor temperature rise, and no pollution to the environment.
