Tsurumi LH23.0W Cast Iron High Head Submersible Drainage Pump for Dewatering with Dual Impellers

When dealing with severe flooding or deep foundation excavations, removing water quickly and reliably is critical to keeping your project on schedule. The Tsurumi LH23.0W is engineered to tackle these exact challenges, providing exceptional dewatering capabilities in demanding environments. Its robust design ensures continuous operation even when partially submerged, giving you peace of mind during critical drainage tasks.

Delivering impressive hydraulic performance, this three-phase pump achieves a maximum flow rate of 600 L/Min and reaches a maximum head of 39 m. Powered by a highly efficient 3 kW motor operating at 415 V, it is perfectly suited for rigorous industrial and construction site duties. The unit draws a rated current of 6.5 Amps, balancing power consumption with heavy-duty output.

At the heart of its liquid handling capability are the dual semi-open impellers, specifically designed to process water containing abrasive solids up to 6mm in diameter. This configuration ensures smooth suction and reduces the risk of clogging when transferring sand-carrying water. The top-discharge, flow-through layout effectively cools the motor, maintaining stable performance during extended dry-run conditions.

Built to withstand harsh conditions, the pump body is constructed from durable cast iron. It features a double-face mechanical seal housed in an oil chamber, completely isolated from the pumped liquid for extended longevity. An integrated Circle Thermal Protector safeguards the motor against overheating, while the watertight cable entry prevents moisture ingress.

FEATURES

• Resists severe wear from abrasive particles, significantly extending the operational lifespan of the internal components.
• Forcibly supplies lubricating oil to the mechanical seal faces even when the oil level drops, ensuring constant protection.
• Utilizes silicon carbide faces in a clean oil environment to provide superior resistance to heat and corrosion.
• Incorporates a strain-relief device and prevents water from traveling up the cable core if the sheath is accidentally damaged.
• Automatically severs the motor circuit if excessive heat or overcurrent is detected, preventing catastrophic electrical failure.
• Maximizes motor cooling efficiency by routing pumped water around the motor frame, enabling safe continuous operation at low water levels.
