Tsurumi LB-480 Submersible Dewatering Pump | 2/3 HP 115V

Product Details

The Tsurumi LB-480 is a professional-grade, manual submersible dewatering pump that has become the "industry standard" for construction site drainage and rental fleets. Equipped with a powerful 2/3 HP motor, this pump is designed to handle water containing sand, silt, and blue-stone dust without clogging or excessive wear. It solves the challenge of high-volume water removal in confined spaces by utilizing a slimline design that fits into 8-inch pipes, while its top-discharge cooling system ensures the motor remains safe even when the water level is low.

Key Features:

• Slimline Design: At only 7-11/16" in diameter, this pump easily fits into 8-inch casings, narrow sumps, and tight excavation trenches.
• Top Discharge & Flow-Through Design: Water flows around the motor during operation, providing maximum cooling efficiency for continuous duty even in shallow water.
• Urethane Semi-Vortex Impeller: Engineered for extreme durability, the urethane material provides superior resistance to abrasive solids compared to standard cast iron or plastic impellers.
• Dual Inside Mechanical Seals: Featuring Silicon Carbide faces, these seals are housed in an oil chamber for the longest possible operational life.
• Patented Oil Lifter: Ensures the mechanical seals are lubricated and cooled regardless of the pump's orientation or falling oil levels.

Specifications:

• Motor Output: 2/3 HP (0.5 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 2" NPT (Top Discharge)
• Max Flow Rate: 62 Gallons Per Minute (GPM)
• Max Head: 39.5 Feet
• Max Solids Handling: 0.236" (6mm)
• Cable Length: 32 Feet (Standard) or 50 Feet (Optional)

Installation & Maintenance Tips:

• Manual Operation: As a manual pump, the LB-480 will run as long as it is plugged in. Always unplug the unit once water has been removed to prevent unnecessary wear.
• Adjustable Discharge: The discharge connection can be reoriented between vertical and horizontal positions to prevent hose kinking in different installation environments.
• Strainer Check: Periodically inspect the bottom suction strainer. While the pump is designed for silt, clearing large leaves or plastic debris will ensure maximum flow and motor cooling.

Common Uses/Applications:

• Construction Dewatering: Ideal for pumping out footings, ditches, and manholes where sandy or silty water is present.
• Residential/Commercial Drainage: Fast water removal from flooded basements, swimming pools, or low-lying landscape areas.
• Industrial Maintenance: Reliable drainage for utility vaults, elevator pits, and factory sumps.

Common Questions:

Q: How does this differ from the LB-480A?

A: The LB-480 (this model) is a manual pump. The "A" version includes an integrated electronic water level sensor for automatic operation.

Q: Can I use a float switch with this pump?

A: Yes, the LB-480 can be converted to automatic operation by using an optional piggyback float switch or the Tsurumi TS-301 vertical float switch.

Q: Is this pump safe for fish ponds?

A: No, the LB-480 is an industrial/commercial dewatering pump containing oil in the seal chamber. It is not intended for use in environments with live fish.

With its rugged urethane construction and high-efficiency cooling design, the Tsurumi LB-480 is the perfect solution for professionals who need a durable, portable pump for demanding site drainage and water removal tasks.
