Head Range:2.5-160m
Motor Power:0.75-150kW
Inlet/Outlet Range:DN25-DN150
Structural Features
- Oil-filled Cooling System
The submersible sewage pump features a fully enclosed, oil-immersed cooling structure within the motor cavity. This design enhances heat dissipation and effectively prevents sewage infiltration, significantly extending the motor's service life.
- Double Mechanical Seals
To enhance durability in challenging environments, our submersible sewage pumps are equipped with a silicon carbide/ceramic double mechanical seal. This robust configuration, combined with an auxiliary oil chamber buffer design, significantly improves sealing reliability and extends the service life of the sewage submersible pumps.
High-chrome Cast Iron Construction
The overflow parts (impeller, pump casing) are made of high chrome cast iron, which is wear-resistant and corrosion-resistant, and is suitable for sewage environments containing solid particles.
Product Advantages
Extended Operational Lifespan
The oil cooling system reduces motor temperature rise by 40% and supports 24-hour continuous operation.
Enhanced Clog Resistance
Large channel impeller design passes 40mm diameter solid particles (cut impeller handles fibrous impurities).
Low Maintenance Requirement
Oil lubrication system reduces mechanical wear and seal replacement intervals are more than 3 times longer than water-cooled pumps.
Energy Efficiency
Hydraulic model optimization, with high efficiency motor, energy saving 15-20% compared with traditional sewage pump.
Application Scenarios
Municipal Sewage Management
Sewage submersible pumps are used in urban drainage networks, wastewater treatment lift stations, and stormwater pumping stations to transport solids-containing wastewater.
- Industrial Waste Handling
- Building Services
Used in basement sewage discharge in high-rises, drainage of shopping mall catchment wells, and emergency pumping in civil defense structures.
- Agricultural & Aquaculture
Applicable for farm manure management, farmland drainage and irrigation, and circulating water systems in fish ponds (medium temperature ≤40°C).
Service Assurance
