A sewage pump is a specialized pump designed to handle wastewater containing solids, debris, and various contaminants.
Structure and Working Principle
It usually has a robust impeller and a volute - shaped casing. The impeller is often designed with large passages or non - clogging features. When the motor starts, the impeller rotates at high speed, generating a centrifugal force. This force draws in the sewage from the inlet. The solids and liquid mixture is then pushed through the pump and discharged from the outlet under pressure.
Applications
Sewage pumps are extensively used in municipal sewage treatment plants. They transport sewage from residential and commercial areas to treatment facilities. In buildings, especially basements or low - lying areas, sewage pumps prevent flooding by removing wastewater. Industrial settings also rely on them to handle process wastewater that may contain chemical residues, suspended solids, or other pollutants.
Features
These pumps are built to be durable and resistant to corrosion due to the harsh nature of the sewage. They have high - efficiency motors to ensure continuous operation and energy - saving performance. Their non - clogging design allows them to handle solids like rags, paper, and small stones without getting blocked, making them an essential part of any wastewater management system.
