Tsurumi Submersible Dewatering Pump NK3-15 3 Inch Discharge Electric (2 HP 111 GPM 69 Ft Head 110V 220V Dual Voltage Mining Construction Water)

Tsurumi NK3-15 2 HP 3-Inch Discharge Dual-Voltage Electric Submersible Dewatering Pump

The Tsurumi NK3-15 Electric Submersible Dewatering Pump combines a continuous-duty 2 HP motor, 3-inch NPT discharge bore, and semi-vortex ductile iron impeller to evacuate high-volume ground runoff at flow rates up to 111 GPM with a maximum total dynamic head of 69 feet. Engineered with an internal terminal board for field-selectable 110V or 220V single-phase power, this high-head utility pump processes abrasive suspended slurry and spherical solids up to 0.334 inches without clogging. Built with a flow-through top discharge casing that provides motor cooling during low-water drawdown, double inside silicon carbide mechanical seals, and an integrated thermal overload protector, it equips excavation contractors, mining operators, and emergency remediation crews with reliable water removal across deep foundations, quarries, and flooded structures.

Best Used For:

• Deep Excavation & Foundation Dewatering: Evacuating ground seepage and muddy surface water from deep footing trenches, elevator shafts, and construction caissons up to 69 feet of vertical lift.
• Quarry, Mining & Utility Runoff Control: Pumping abrasive sediment-laden wash water, sand slurry, and retention pond overflow containing suspended aggregate solids up to 0.334 inches.
• Municipal Flood & Disaster Remediation: Rapidly clearing inundated commercial basements, subterranean parking vaults, and municipal storm runoff at high delivery volumes up to 6,660 GPH.

Key Performance & Safety Features

• Continuous-Duty 2 HP Electric Motor: High-torque copper-wound motor delivers reliable 3,440 RPM pumping power across heavy-load industrial drainage applications.
• Dual-Voltage Field Configurable: Factory-installed internal terminal board allows seamless electrical reconnection between 110V and 220V single-phase supply lines.
• Flow-Through Top Discharge Design: Circulates pumped water across the motor housing to maintain optimal operating temperatures even in low-water continuous drawdown.
• Abrasion-Resistant Semi-Vortex Impeller: Multi-vane ductile cast iron impeller and synthetic rubber wear plates resist erosion from abrasive sand and aggregate slurry.
• Dual Inside Silicon Carbide Mechanical Seals: Premium SiC seal faces isolated in an oil bath with an integrated Oil Lifter mechanism prevent seal failure from dry running.
• Built-In Thermal & Amperage Protector: Automatically shuts down power during excessive thermal buildup, locked impeller conditions, or voltage spikes to prevent motor burnout.

Technical Specifications

Pro-Tip: When deploying the pump in sandy or sediment-heavy sumps, suspend the unit 6 to 12 inches above the bottom using a safety tether or set it upon a solid base plate; elevating the strainer prevents abrasive solids from packing around the intake during continuous drawdown.
