The DWB80 and RWB80 are reliable 80mm sewerage pump models developed for fast and practical transfer of dirty water, wastewater and liquid containing soft solids. Designed for demanding field conditions, these 3 inch trash pump units combine strong drainage capacity with simple maintenance and convenient transport. With a flow rate of up to 45m³/h, a pump lift of 25m and a suction head of 7m, they are suitable for construction drainage, agricultural irrigation, flood control, site dewatering and general industrial water transfer. Available in diesel and gasoline engine versions, this sewerage pump series offers stable performance, easy impeller access and a lightweight aluminium pump housing, making it a dependable choice for professional users, distributors and project buyers.
The DWB80 and RWB80 sewerage pumps are built for users who need a portable and durable dirty water pump for daily outdoor work. These self-priming trash pumps are suitable for pumping water with soft granules and can handle up to 30% solid sewerage, which makes them ideal for muddy water, wastewater and drainage jobs where a standard clean water pump is not enough. The rugged frame protects the machine during transport and operation, while the wear-resistant seal, carbon ceramic shaft gasket and easy impeller removal design help reduce maintenance time. Whether you need a diesel sewerage pump for heavy-duty use or a gasoline trash pump for flexible field mobility, this range provides an efficient and export-friendly solution.
