Tsurumi Submersible Pump LB-480 2 Inch Discharge Dewatering Machine (0.67 HP 115V 63 GPM 39ft Head Slimline Trash Vault Drainage Excavation Utility)

Tsurumi LB-480 2/3 HP 115V 2" Slimline Submersible Dewatering Trash Pump

The Tsurumi LB-480 2/3 HP (0.67 HP) submersible dewatering pump evacuates flooded foundation trenches, drains residential utility vaults, empties municipal manholes, and transfers abrasive sand-laden wastewater at flow rates up to 63 GPM (3,780 GPH) with a maximum head lift of 39 feet. Engineered with a continuous-duty 115V single-phase motor, patented internal oil lifter lubrication, and dual silicon carbide mechanical seals, this portable 2-inch NPT top-discharge unit survives extended dry-running and low-water operation without thermal stator failure. Featuring a compact 7.44-inch cylindrical slimline profile that deploys into standard 8-inch pipe casings, paired with a wear-resistant urethane rubber semi-vortex impeller that passes abrasive suspended solids without clogging, it equips civil utility crews, site contractors, and commercial equipment rental fleets with reliable, continuous drainage across severe jobsite conditions.

Best Used For:

• Excavation Trench and Footing Dewatering: Evacuating muddy ground seepage, rainwater pooling, and abrasive sand slurry from open construction footings and foundation excavations.
• Confined Manhole and Utility Vault Drainage: Lowering into narrow 8-inch electrical vault casings, telecom manholes, and drainage sumps for continuous floodwater clearance.
• Commercial Basement and Elevator Pit Pumping: Clearing accumulated dirty groundwater and nuisance floor water down to minimal residual depths without motor overheating.

Key Performance & Safety Features

• Dual Silicon Carbide Mechanical Seals: Premium seal faces located inside an isolated oil chamber provide exceptional abrasion resistance against sandy, gritty slurry water.
• Patented Internal Oil Lifter: Ensures constant mechanical seal lubrication and cooling across all water levels, extending operational seal life.
• Abrasive-Resistant Urethane Semi-Vortex Impeller: High-durability elastomer impeller geometry resists wear while creating a vortex path that clears suspended solids without clogging.
• Top-Discharge Flow-Through Motor Cooling: Pumped water routes directly around the aluminum motor housing to dissipate heat, allowing continuous operation at low water levels.
• Slimline 7.44-Inch Cylindrical Architecture: Narrow diameter enables fast deployment into 8-inch pipes, conduit vaults, and cramped excavation sumps.
• Heavy-Duty 32-Foot Power Cord: Industrial-grade submerged power cable with molded strain relief provides extended jobsite reach without dangerous extension cord splices.

Technical Specifications

Pro-Tip: When lowering the LB-480 into deep utility vaults or muddy excavation pits, always suspend and position the pump using a dedicated nylon rope tied to the built-in lifting handle; never lift or suspend the unit by its power cord, as cable tension can compromise the watertight entry seal.
