Rock Machinery RWP-28 Dirty 3" Water Pump

A high-capacity 6.5HP petrol water pump specifically engineered to transfer waste and dirty water containing small particles. With a 37 m³/h flow rate and 3" inlet/outlet ports, it is an essential tool for managing floodwaters, draining pools, or clearing wastewater from construction sites.

Powerful Throughput: Driven by a 6.5HP (4kW) engine, this pump achieves a maximum flow of 37,000 litres per hour, making quick work of large volumes of water.
Particle Handling: Unlike standard clear-water pumps, the RWP-28 is designed to manage "dirty" water, allowing for the passage of small debris and particles without clogging the internal components.
Inlet & Outlet: Features large 3" (80mm) diameter ports to maximize volume and reduce the risk of blockages during heavy-duty suction tasks.
Impressive Lift: Offers a maximum suction lift of 6m and a total head lift of 20m, providing plenty of power to move water up from deep trenches or over high barriers.
Ready to Work: The unit weighs 34kg and comes supplied with a suction filter, pipe fitting attachments, and an engine funnel to get you started immediately (requires separate hoses).

Rock Machinery RWP-28 Dirty 3" Water Pump – High-Volume Waste Transfer

The Rock Machinery RWP-28 is a heavy-duty petrol water pump engineered for high-capacity fluid management.

Designed specifically for "dirty water" applications, this pump features a robust internal construction capable of handling water containing suspended solids and particles. Powered by a reliable 6.5hp engine, it is an essential tool for site engineers, farmers, and emergency responders who need to move large volumes of wastewater, clear flooded excavations, or drain ponds and pools quickly.

Key Features

High-Volume 3" Throughput: Features large 3" (75mm) inlet and outlet ports, allowing for a massive maximum flow rate of 37 $m^3/h$. This makes it ideal for rapid dewatering of large areas.
Powerful 6.5hp Engine: The 4kW petrol engine provides the torque necessary to maintain high flow rates even when pumping denser, particle-heavy wastewater.
Dirty Water Capability: Specifically built to manage water containing debris, making it far more versatile for construction sites and agricultural drainage than standard "clean water" pumps.
Impressive Lift Performance: Offers a 20m maximum head (lift) and a 6m suction lift, providing the vertical reach required for deep trenches, basements, or high-banked reservoirs.
Rugged Site Frame: Mounted in a heavy-duty steel wrap-around frame, protecting the engine and pump components while providing convenient points for two-person transport and secure positioning.
Rapid Priming: Features an efficient pump housing design with a suction time of 240 seconds, ensuring the unit gets to work quickly once the housing is primed.
Complete Attachment Kit: Supplied with a suction filter, pipe fitting attachments, and an engine oil funnel to streamline the initial setup and protect the pump from over-sized debris.

Engineered for Site Drainage and Flood Management

The RWP-28 is a primary asset for professionals facing challenging environmental conditions. Unlike electric pumps, its petrol-powered design allows for operation in remote areas without access to the grid. The inclusion of a heavy-duty suction filter ensures that while it handles "dirty" water, larger stones or damaging debris are kept out of the impeller housing, significantly extending the life of the unit.
