The DWB80 (diesel) and RWB80 (gasoline) sewerage trash pumps are robust, engine-driven solids-handling centrifugal pumps engineered for heavy-duty wastewater and dewatering operations throughout Europe.
Powered by reliable air-cooled 4-stroke single-cylinder engines – diesel 170F for the DWB80 or premium Robin EY20 5.0HP gasoline for the RWB80 – these trash pumps deliver a consistent 45 m³/h flow rate, 25-meter maximum lift, and guaranteed 7-meter suction head. Designed to handle liquids with up to 30% solid content and soft particles as large as 30mm without clogging, they feature lightweight aluminium pump housing for excellent corrosion resistance and portability (36kg gasoline version, 53kg diesel).
Key maintenance-friendly elements include a replaceable wear plate, easy impeller removal, long bolt assembly for quick disassembly, and durable carbon ceramic mechanical seals. With recoil start for safe, electricity-free operation and aluminium access ports for secure connections, the DWB80/RWB80 series stands out as the professional choice for construction site dewatering, municipal sewage management, flood response, and industrial wastewater tasks requiring dependable, high-volume solids-handling performance.
Product Description
The DWB80 and RWB80 sewerage trash pumps are heavy-duty solids-handling centrifugal pumps designed to manage demanding wastewater and dewatering tasks across Europe. Available with either a reliable diesel (170F) or gasoline (Robin EY20 5.0HP) air-cooled 4-stroke OHV single-cylinder engine, these gas powered and diesel trash pumps excel at pumping liquids containing up to 30% solids and particles as large as 30mm without clogging. Featuring a guaranteed 7-meter suction head, 25-meter maximum lift, and impressive 45 m³/h flow rate, they provide robust performance in challenging environments. The lightweight aluminium pump housing, easy-maintenance wear plate, wear-resistant carbon ceramic seals, and simple impeller removal make service straightforward with standard tools. With recoil start portable pump safe operation and no need for external power, these sewerage pumps are the professional choice for construction sites, municipal sewage handling, flood response, and industrial wastewater management where reliable solids-handling capability is essential.
