Tsurumi LB480, LB800 & LB1500 Submersible Pumps

The Tsurumi LB Series Submersible Drainage Pump lineup is an industry favorite for contractors, hire fleets, and civil utility teams requiring robust, continuous-duty dewatering in compact spaces.

Featuring a top-discharge flow-through design, the pumped liquid flows directly past the motor housing, cooling the motor even when operating near dry levels. Built with high-abrasion resistance in mind, the LB range easily handles dirty, sand-laden site water without premature wear or motor strain.

Key Features & Benefits

• Top-Discharge Design: Allows continuous operation at low water levels without motor overheating and enables easy deployment into narrow pipes or sumps.
• Wear-Resistant Impeller: Urethane rubber impeller and synthetic rubber pump casing provide superior resistance against sand, silt, and site debris.
• Patented Oil Lifter: Ensures double mechanical seal faces remain continuously lubricated, even if oil levels drop or the pump operates horizontally.
• Anti-Wicking Cable Entry: Blocks water ingress into the motor chamber if the power cable gets damaged or submerged at the entry point.
• Versatile Power Options: Offered across popular job-site models including the LB480 (0.48kW), LB800 (0.75kW), and LB1500 (1.5kW) in 110V and 230V configurations.

Applications

• Dewatering construction site excavations, trenches, and footings
• Pumping flooded basements, manholes, and cable vaults
• Trade effluent drainage and rain runoff removal
• General site hire and emergency flood response

Note: For automatic operation, optional electrode level control switches (TSURUMI LB-A models) can be fitted to prevent dry-running and lower site electricity costs.
