Product Overview

The External Single Pump Sewage Lifting Unit is a compact, fully enclosed, high-reliability sewage lifting system designed for domestic, commercial, and industrial wastewater scenarios.

It efficiently collects and pumps sewage from low-lying areas where gravity discharge is not possible-such as basements, underground spaces, and remote facilities.

Compatible with toilets, urinals, showers, bathtubs, wash basins, laundry rooms, kitchens, and other drainage points, it ensures stable, clean, and odor-free wastewater discharge.

As a professional manufacturer, we provide durable, safe, and highly efficient lifting solutions tailored to various application needs.

Key Features & Advantages

1. Domestic Sewage Discharge

In basements, underground parking lots, and other low-lying areas, gravity drainage is often unavailable.

The External Single Pump Sewage Lifting Unit:

Collects and lifts domestic sewage from toilets, kitchens, laundry rooms, etc.

Ensures timely discharge into the municipal pipe network

Prevents wastewater accumulation and odor problems

2. Commercial Wastewater Treatment

Suitable for shopping malls, restaurants, hotels, and similar venues with large sewage output.

The system:

Efficiently handles kitchen and restroom wastewater
