Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, specifically a submersible pump. Background Technology

[0002] A submersible pump is a type of pump that operates directly in water. Its core working principle is to drive the impeller to rotate through a motor, generating centrifugal force to draw water into the pump body and pressurize it for discharge.
