VOLVO DD25B STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD25B is a compact smooth drum roller engineered for high productivity and precision compaction. It features a Kubota D1803-M three-cylinder, water-cooled, naturally aspirated diesel engine delivering around 25 hp at 2,200–2,700 rpm, optimized for reliable power and fuel efficiency without requiring complex after-treatment systems. The roller weighs 5,545 lbs with ROPS and measures approximately 8 ft 4 in in length, 3 ft 6.9 in in width, and 116.3 in in height. Its dual drums have a width of 47.2 inches, providing a 43-inch operating width, enabling smooth and mark-free compaction. The DD25B offers a high-frequency vibration of 55 to 67 vibrations per minute (vpm) with an amplitude of 0.021 inches, delivering powerful compaction equivalent to larger machines. The machine’s 110-inch inside turning radius and 68-inch wheelbase afford excellent maneuverability in confined spaces. Designed for operator comfort and safety, the compactor includes a 360-degree visibility layout, easy-access engine compartment, and a rust-proof pressurized water system ensuring consistent flow on drum surfaces to prevent asphalt pickup. The water spray system with eight nozzles is easily serviceable and water-efficient. Maintenance is minimized with durable, urethane drum wipers and lifetime-lubricated eccentric bearings. Its hydraulic system pairs with the engine for optimal performance and fuel savings around 7% over previous models. Travel speed reaches up to 6 mph, allowing efficient forward and reverse compaction. This combination of features makes the Volvo DD25B ideal for asphalt paving and other smooth compaction applications requiring high finish quality and operational uptime.
