Tsurumi LSR2.4S-61 Low Level Submersible Residue Pump | 0.5 HP 115V

Product Details

The Tsurumi LSR2.4S-61 is a high-performance, submersible residue drainage pump designed specifically for applications where water must be removed down to the lowest possible level. This 0.5 HP powerhouse is capable of pumping water down to 0.4 inches (10mm), making it an essential tool for emergency dewatering. It solves the problem of "nuisance water" left behind by standard submersible pumps, ensuring floors and surfaces are left nearly dry without the need for manual mopping or vacuuming.

Key Features:

• Low-Level Drainage: Specifically engineered to pump water down to a depth of 0.4 inches, ideal for flat surfaces.
• Built-in Swing Check Valve: Prevents the backflow of water from the discharge hose when the pump is turned off, ensuring the area stays dry.
• Urethane Semi-Vortex Impeller: Highly resistant to wear and abrasion, providing maximum durability when handling water containing small debris or sand.
• Patented Oil Lifter: Provides lubrication to the seal faces even if the oil level falls, significantly extending the life of the mechanical seal.
• Rubber Stand: The bottom is equipped with a rubber stand that protects the floor or tank surface from scratches and damage.

Specifications:

• Motor Output: 0.5 HP (0.4 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 2" NPT (Top discharge)
• Max Flow: 62 Gallons Per Minute (GPM)
• Max Head: 40 Feet
• Dimensions: 8-1/4" Diameter x 11-1/8" Height
• Cable Length: 32 Feet (Standard)

Installation & Maintenance Tips:

• Operation Level: For the pump to prime initially, the water level must be at least 1 inch deep. Once running, it will continue to pump down to 0.4 inches.
• Cleaning: Periodically check the suction strainer for debris. A clogged strainer can reduce flow and cause the motor to overheat.
• Submergence: While the motor is water-cooled, do not allow the pump to run completely dry for extended periods to ensure the longevity of the mechanical seals.

Common Uses/Applications:

• Flooded Basements: Rapidly removes standing water from concrete floors after heavy rain or pipe bursts.
• Construction Sites: Drains flat roofs, parking lots, or foundation footings where shallow water accumulates.
• Maintenance Tasks: Ideal for emptying swimming pools, decorative fountains, and small utility tanks.

Common Questions:

Q: Does this pump require a float switch?

A: The LSR2.4S-61 is a manual pump. To operate it automatically, it can be paired with an optional Tsurumi TS-303 or similar electronic water level sensor.

Q: Can it handle solids?

A: While the urethane impeller is abrasion-resistant, this pump is designed for clean or grey water. It is not intended for sewage or large solid handling.

Q: Why is it discharging from the top?

A: The top discharge design allows the pumped water to flow around the motor, providing a cooling effect that allows the pump to operate even when the water level is very low.

With its rugged construction and specialized low-level intake, the Tsurumi LSR2.4S-61 is the perfect solution for demanding dewatering tasks where every inch of water counts.
