Compared with general horizontal pumps or vertical sewage pumps, submersible sewage pumps have obvious advantages in the following aspects:
1. Compact structure and small footprint. Since submersible sewage pumps work under the liquid, they can be directly installed in the sewage pool. There is no need to build a special pump room to install pumps and machines, which can save a lot of land and infrastructure costs.
2. Easy installation and maintenance. Small sewage pumps can be installed freely, and large sewage pumps are generally equipped with automatic coupling devices for automatic installation, which is very convenient for installation and maintenance.
3. Long continuous operation time. Since the sewage pump and the motor are coaxial, the shaft is short, and the rotating parts are light, the load (radial) on the bearing is relatively small, and the life is much longer than that of ordinary pumps.
4. There are no problems such as cavitation damage and water diversion. In particular, the latter point brings great convenience to the operator.
Because of the above advantages, submersible sewage pumps have been increasingly valued by people, and their application scope has become wider and wider, from being used to simply transport clean water to being able to transport various domestic sewage, industrial wastewater, construction site drainage, liquid feed, etc. It plays a very important role in municipal engineering, industry, hospitals, construction, restaurants, water conservancy construction and other industries.
