The advantages of sewage lifting and discharge pumps are: low vibration noise, low motor temperature increase; Compact structure and small footprint; Submersible pump is a type of pump that is connected to a motor and can be directly installed in a sewage tank without the need to build a dedicated pump room for installing the pump and motor, which can save a lot of land and infrastructure costs; Easy installation and maintenance. Small submersible sewage pumps can be installed by themselves, while large submersible sewage pumps are equipped with automatic coupling devices for easy installation and maintenance; Long continuous operation time and long lifespan.

The difference between submersible pumps and self-priming pumps:

1. Submersible pumps operate underwater for a long time, while self-priming pumps work on the shore

2. The installation of submersible pumps is relatively convenient, they can be directly put into the water and powered on to work. The installation of self-priming pumps is more complicated, requiring the connection of pipelines and installation on the shore

3. The price of submersible pumps is lower than that of self-priming pumps for the same flow rate and head

4. Due to the long-term operation of submersible pumps underwater, it is easy to encounter problems such as water ingress, motor damage, or cable aging. However, self-priming pumps work on shore and do not have this problem

If using a lower power, it is recommended to use a submersible pump because submersible pumps have lower costs and are easier to operate. If the power is higher or long-term fixed work is required, self-priming pumps are recommended for lower maintenance costs.
