Product Overview

This external dual-pump PE sewage lifter is a new-generation intelligent sewage discharge equipment independently developed by our company for large-flow and continuous heavy sewage working conditions. It can be fitted with cutting sewage pumps to handle complex sewage containing hair, paper scraps and fine solid impurities. The equipment adopts a dual-pump standby operation logic. If one pump fails, the other will automatically switch to avoid the risk of drainage interruption, making it ideal for underground places with heavy foot traffic and frequent water consumption. The unit delivers remarkable energy-saving performance with an energy saving rate of 20%-50%. The lightweight tank greatly saves pump room space and eliminates the need for traditional civil pumping stations. Sewage is transported in a fully sealed system. Impurities at the source are crushed and discharged automatically along with water flow, removing the need for frequent manual cleaning. It enables stable 24-hour unattended operation without pollution.

Core Features

1. Dual-pump configuration (one operational, one standby): The two pumps work alternately and switch automatically upon failure to guarantee continuous drainage, suitable for high-load commercial applications.
2. Integrally molded PE tank: Made of high-density polyethylene, corrosion-resistant and leak-free. The fully sealed structure isolates odor and prevents mosquito breeding.
3. External cutting pump structure: The externally arranged pump facilitates maintenance. The cutting impeller crushes debris to fundamentally prevent pipeline and pump blockage.
4. Intelligent automatic control system: Automatically starts and stops via liquid level sensing, equipped with multiple protection alarms for overload, water shortage and high liquid level.
5. Multiple volume options: Tank volumes of 50L/85L/160L/300L/500L are available to meet different drainage flow requirements.
6. Lower construction cost: The unit is pre-assembled. Only inlet and outlet pipelines need to be connected on site, saving expenses for sewage tank excavation and anti-seepage construction.

Application Scenarios

Large shopping mall public restrooms, basement floors of hotels and clubs, underground bathrooms in hospitals, office building basements, underground supporting facilities of transportation hubs and other sites requiring large-flow and long-term continuous sewage discharge.
