The drainage pumps used in buildings include submersible sewage pumps, submersible sewage pumps, vertical sewage pumps, and horizontal sewage pumps.
Due to the small size of the building and the low drainage volume, submersible sewage pumps and underwater sewage pumps can be preferred for drainage. Underwater sewage pumps are generally used in important places; Vertical and horizontal sewage pumps require seismic isolation foundations, self-priming suction, and occupy a certain amount of space, so they are less commonly used in buildings.
