Open Impeller Submersible Sewage Pump

Open Impeller Submersible Sewage Pump is a good choice for using in Sewage discharge, urban sewage treatment, environmental protection projects, etc. Wastewater discharge and treatment of facilities such as hospitals, hotels, residential areas, and subways. It can also be used for the discharge of slurry in construction sites. It is non-clog and suitable for water with soft fibers too.

Key Features and Benefits

1. Open Impeller Design for Improved Anti-Clogging Performance

The open impeller provides a larger passage for solid particles and fibrous materials to pass through smoothly. It is especially suitable for wastewater containing suspended solids or soft fiber contaminants.

2. Large Flow Capacity for Heavy-Duty Applications

With flow rates up to 5500m³/h and power ratings up to 550kW, the pump can handle large-scale wastewater transfer requirements in municipal and industrial projects.

3. Flexible Material Options for Different Media

Different materials are available according to the corrosion and abrasion conditions:
Cast Iron: Suitable for general municipal sewage and standard wastewater applications.
SS304 Stainless Steel: Suitable for mildly corrosive wastewater and food processing industries.
SS316/SS316L Stainless Steel: Designed for chemical wastewater and seawater environments.
Duplex Stainless Steel: Recommended for high chloride, highly abrasive and severely corrosive applications.

4. Multiple Installation Methods

The pump supports different installation configurations including automatic coupling, fixed wet installation, fixed dry installation and portable installation, providing flexibility for various sewage systems.
