WLT Large Flow Submersible Pump for Municipal Drainage and Irrigation Systems
product Introduction
The WLT Series High Flow Submersible Pump is engineered for applications requiring high flow rates and low head, making it an ideal solution for rapid water transfer, flood control, drainage, and circulation systems. Designed with a stainless steel pump casing and a bronze impeller, the pump offers excellent corrosion resistance, high mechanical strength, and reliable performance in freshwater, seawater, brackish water, and sand-containing environments.
Its compact submersible design eliminates the need for a conventional pump house, significantly reducing installation costs while providing flexible deployment and easy maintenance. With an IP68-rated motor, the WLT Series is built for continuous underwater operation in demanding industrial, municipal, agricultural, and aquaculture applications.
Design Features & Technical Advantages
High-Performance Motor & Sealing System
- High-efficiency copper-winding motor with Class F insulation for reliable continuous-duty operation.
- Built-in thermal protection automatically prevents overheating and overload damage.
- Heavy-duty double mechanical seals made of tungsten carbide and fluororubber provide outstanding sealing performance and extended service life.
- Resin-sealed cable entry ensures excellent waterproof protection under submerged conditions.
Optimized Hydraulic Design
- Precision-cast bronze impeller offers superior resistance to seawater corrosion and abrasive wear.
- Large flow passages reduce the risk of clogging when pumping water containing sand, fibers, or suspended particles.
- Smooth stainless steel casing minimizes hydraulic losses and improves overall pumping efficiency.
- Optional agitator system helps prevent sediment accumulation and improves drainage performance.
Intelligent Protection System
- Standard float switch enables automatic start and stop based on water level.
- Built-in leakage sensor immediately shuts down the pump if seal failure is detected.
- Compatible with automatic guide rail coupling systems for quick installation and safe maintenance without entering the pump pit.
Compact & Service-Friendly Design
- Lightweight structure allows convenient transportation and installation.
- Modular construction enables fast replacement of wear parts, reducing maintenance time and operating costs.
- Designed for long-term continuous operation with minimal servicing requirements.
Typical Applications
Aquaculture & Marine Farming
Ideal for seawater circulation, water exchange, oxygen supply, and emergency drainage in fish farms, shrimp ponds, crab farms, oyster farms, and other aquaculture facilities. The bronze impeller provides excellent resistance to seawater corrosion.
Agricultural Irrigation & Flood Drainage
Suitable for farmland irrigation, orchard water supply, drainage canals, pumping stations, and rapid floodwater removal during heavy rainfall.
Municipal Emergency Drainage
Widely used for urban flood control, underground parking garages, subway tunnels, construction sites, and temporary emergency pumping projects where rapid water removal is essential.
Industrial Water Transfer
Designed for wastewater transfer and process water circulation in food processing plants, paper mills, slaughterhouses, and other industrial facilities handling water containing suspended solids and light debris.
