Tsurumi LSC1.4S-61 Submersible Residue Drainage Pump | 0.5 HP 115V

Product Details

The Tsurumi LSC1.4S-61 is the industry standard for complete residue water removal. This high-performance "puddle sucker" is specifically engineered to pump water down to a remarkable 0.04 inches (1mm), effectively leaving surfaces dry. It solves the problem of standing water on flat surfaces—such as basements, parking garages, and construction slabs—where standard submersible pumps fail to prime or leave too much liquid behind. Compact and lightweight, it is the ultimate tool for emergency restoration and facility maintenance.

Key Features:

• Ground-Level Drainage: Specialized suction intake allows the pump to drain water down to 0.04 inches (1mm), the lowest level in its class.
• Built-in Swing Check Valve: Prevents the backflow of water from the discharge hose when the motor stops, ensuring the area stays dry after pumping is complete.
• Urethane Semi-Vortex Impeller: Provides maximum durability and maintains pump performance even when handling abrasive sand or silt.
• Patented Oil Lifter: Ensures the mechanical seals remain lubricated and cooled, even if the oil level is low or the pump is installed horizontally, significantly extending the motor life.
• Non-Marring Bottom: The base is made of specialized ethylene propylene rubber to protect decorative floors or delicate tank liners from scratches.

Specifications:

• Motor Output: 0.5 HP (0.48 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 1" NPT (Top Discharge)
• Max Flow Rate: 45 Gallons Per Minute (GPM)
• Max Head: 39 Feet

• Weight: 26 lbs (Dry)
• Power Cord: 32-Foot Heavy Duty Submersible Cable

Installation & Maintenance Tips:

• Initial Priming: To start the pump, the initial water level must be at least 0.4 inches (10mm). Once primed, it will continue to pump down to its minimum level.
• Hose Selection: For maximum efficiency, use a reinforced discharge hose to prevent kinking, which can put unnecessary backpressure on the 1" NPT outlet.
• Suction Screen Care: Periodically clear the suction strainer of hair, plastic, or large debris to maintain the high-velocity intake required for low-level pumping.

Common Uses/Applications:

• Flood Restoration: Ideal for removing shallow water from basements, hallways, and living areas after heavy rainfall or plumbing failures.
• Construction Slabs: Drains flat roofs and newly poured concrete foundations where water pools in low spots.
• Facility Maintenance: Used by janitorial and maintenance crews to empty elevator pits, parking garages, and utility vaults.

Common Questions:

Q: How does this differ from the LSR series?

A: While both are residue pumps, the LSC (this model) is more compact and designed for even lower levels (down to 0.04"), whereas the LSR is typically used for slightly deeper residue tasks (down to 0.4").

Q: Can I use this with an automatic switch?

A: This is a manual-operation pump. However, it can be easily converted to automatic operation using an optional piggyback float switch or an electronic water level sensor.

Q: Will the pump burn out if it runs dry?

A: The motor is water-cooled by the flow of water around the motor frame. While the Oil Lifter protects the seals, it is best practice to unplug the pump once the water has been fully removed.

With its rugged urethane construction and industry-leading 1mm drainage capability, the Tsurumi LSC1.4S-61 is the perfect solution for professionals who need to leave a surface as dry as possible, as fast as possible.
