Multiquip QP3TH 3" Honda GX240 Gasoline Engine Centrifugal Trash Dewatering Pump
The Multiquip QP3TH 3-inch gasoline engine-driven centrifugal trash pump evacuates high-volume floodwaters, construction runoff, and suspended spherical solids up to 1.5 inches across commercial civil works, foundation footings, and utility excavation trenches. Powered by a 7.9 HP Honda GX240 4-stroke overhead-valve engine, this 142-lb heavy-duty dewatering pump generates up to 396 GPM (1,500 LPM) with a maximum total dynamic head of 95 feet and 25 feet of suction lift. Constructed with a rugged die-cast aluminum casing, ductile cast-iron volute and impeller, dual 3-inch discharge ports for flexible hose routing, a tool-free cleanout cover, and an oil-alert safety system, it delivers continuous, clog-resistant site drainage across municipal utility repairs and large-scale emergency flood remediation.
Best Used For:
- Excavation Foundation and Pipeline Trench Dewatering: Rapidly clearing muddy water, rock slurry, and gravel fragments from deep civil engineering excavations and foundation footings.
- High-Capacity Water Truck and Tanker Filling: Pumping water from retention ponds, lakes, and rivers at 396 GPM to supply dust-control and compaction water tankers.
- Municipal Flood Remediation and Disaster Response: Diverting storm runoff and overflowing wastewater from street intersections, retention basins, and utility vaults.
Key Performance & Safety Features
- 7.9 HP Honda GX240 OHV Engine: Commercial-grade 4-stroke gas engine supplies dependable starting power and high torque with low emissions.
- High-Volume 396 GPM Discharge Flow: Moves up to 1,500 liters per minute to evacuate massive water volumes and lower jobsite water levels quickly.
- 1.5-Inch Solid Debris Clearance: Abrasion-resistant ductile cast iron impeller processes debris, sticks, gravel, and sludge up to 1.5 inches without binding.
- Dual 3-Inch Discharge Ports: Multi-directional outlet design allows versatile layout options and dual-hose split runs across complex site elevations.
- Tool-Free Access Cleanout Cover: Removable front access plate allows fast chamber inspection and obstruction clearing without hand tools.
