Description
De-water flooded construction footings, utility trenches, and irrigation ditches on schedule. The Tsurumi 2In Centrifugal Pump with Honda engine clears standing water across harsh worksites. A commercial 118cc Honda GX120 engine drives a cast-iron impeller. Centrifugal pump mechanics require manual water priming in the casing before suction lines pull liquid.
High-strength die-cast aluminum forms the pump volute and casing to minimize transport weight. A commercial 118cc Honda GX120 OHV gas engine provides shaft power through a forged steel crankshaft. Cast-iron impellers and volutes resist abrasion wear from suspended sand and fine gravel. Carbon ceramic mechanical seals run in an oil bath to endure prolonged operation. Tubular steel roll-cages protect components.
Centrifugal De-Watering Specs Overview
Trenching crews clear rainwater from foundation footings fast without commercial electricity. The lightweight aluminum build allows two workers to carry the pump across rough terrain.
- Commercial 118cc Honda engine provides dependable starting torque across all work shifts
- Cast-iron centrifugal impeller delivers 137 GPM maximum water discharge capacity
- Die-cast aluminum casing cuts unit weight for fast jobsite transport and loading
- Tubular steel roll-cage shields engine and pump components from crushing worksite impacts
- Carbon ceramic mechanical shaft seal prevents water leaks into the engine crankcase
- Standard 2-inch NPT suction and discharge ports hook straight to commercial contractor hoses
- Rubber vibration isolators absorb engine pulses to stop pump walking on concrete
Engine Dyno De-Watering Telemetry
Dynamometer bench testing confirms the 118cc engine maintains 3500 RPM under a 20-foot dynamic discharge head. Fluid flow stabilizes at 112 GPM through 50 feet of 2-inch lay-flat hose. Sump oil temperature reaches 182°F after 3 continuous hours of full-throttle pumping. Fuel consumption registers 0.34 GPH. Sound telemetry indicates 84 dBA at 5 meters distance.
Worksite Performance Practical Notes
You lift this compact pump across jobsites using the tubular steel roll cage. The low center of gravity keeps the pump upright on muddy ditch banks. Do not start this engine without filling the pump housing with water first. Operating the pump dry ruins the carbon ceramic shaft seal within 60 seconds.
- Fill the pump priming port with clean water before pulling the starter cord
- Inspect the suction hose gasket for tight sealing to prevent vacuum air leaks
- Drain the pump casing plug before winter storage to prevent freeze cracking
