Tsurumi HSZ2.4S-62 Automatic Submersible Pump | 0.5 HP 115V

Product Details

The Tsurumi HSZ2.4S-62 is a professional-grade automatic submersible pump designed for reliable, hands-free operation in demanding dewatering environments. Featuring a powerful 0.5 HP motor, this pump is equipped with an integrated vertical float switch that automatically starts and stops the pump based on water levels. It solves the problem of manual monitoring and prevents dry-run damage, making it the ideal solution for narrow sumps or pits where traditional tethered floats might become obstructed.

Key Features:

• Automatic Vertical Float Switch: Built-in switch ensures automatic operation and fits perfectly in confined spaces, preventing the pump from running dry and extending motor life.
• Built-in Shaft-Mounted Agitator: Prevents "air lock" and actively stirs the water to keep sand, silt, and debris in suspension, allowing them to pass through the pump without clogging.
• Urethane Semi-Vortex Impeller: Offers maximum durability and resistance to abrasive materials, outperforming standard cast iron impellers in harsh conditions.
• Dual Inside Mechanical Seal: Housed in an oil chamber with Silicon Carbide faces, providing the industry's best protection against moisture and seal wear.
• Patented Oil Lifter: Ensures the mechanical seals are continuously lubricated and cooled, even if the pump is tilted or oil levels are low.

Specifications:

• Motor Output: 0.5 HP (0.4 kW)
• Voltage: 115V / 1-Phase / 60Hz
• Discharge Size: 2" NPT (Side Discharge)
• Max Flow Rate: 53 Gallons Per Minute (GPM)
• Max Head: 39 Feet
• Max Solids Diameter: 0.275" (7mm)
• Cable Length: 20 Feet (Standard)

Installation & Maintenance Tips:

• Sump Clearance: Ensure the vertical float has at least 1-2 inches of clearance from the sump wall to prevent it from sticking or snagging on debris.
• Cleaning the Agitator: Periodically inspect the agitator and suction strainer for stringy materials (like rags or long weeds) that may wrap around the shaft and restrict rotation.
• Stable Placement: Always place the pump on a flat, solid surface. If the bottom of the pit is extremely silty, consider placing the pump on a brick to prevent it from "burying" itself.

Common Uses/Applications:

• Construction Site Drainage: Perfect for automatically clearing water from trenches, pits, and excavations containing sand and silt.
• Residential & Commercial Sumps: Provides reliable protection for basements and utility rooms that require a compact, automatic pump.
• Industrial Maintenance: Used for draining elevator pits, parking lot catch basins, and small wastewater tanks.

Common Questions:

Q: Can I use this pump for sewage?

A: No, the HSZ2.4S is a dewatering pump designed for water with small solids (up to 0.275"). It is not intended for the large solids or stringy waste found in raw sewage.

Q: Does the float switch require a separate power cord?

A: No, the float switch is fully integrated into the pump's internal wiring. You simply plug the main power cord into a standard 115V outlet.

Q: What happens if the vertical float gets dirty?

A: Heavy grease or mud buildup on the float can affect its buoyancy. It is recommended to spray the float assembly with a hose occasionally to ensure smooth vertical travel.

With its compact automatic design and heavy-duty solids-handling capabilities, the Tsurumi HSZ2.4S-62 is the ultimate "set it and forget it" solution for professional dewatering tasks.
