Tsurumi Submersible Trash Pump HS3.75S 3 Inch Dewatering Machine (1 HP Motor 115V Electric 73 GPM 60-Foot Head Agitator Sand Solids Slurry)

Tsurumi HS3.75S 1 HP 115V 3" Submersible Trash & Slurry Dewatering Pump with Agitator

The Tsurumi HS3.75S 1 HP electric submersible trash pump evacuates high-volume sediment slurries, discharges abrasive groundwater from deep commercial excavations, drains flooded jobsite structures, and clears municipal retention basins containing sand and spherical solids up to 0.25 inches (7 mm) in diameter. Powered by a continuous-duty 115V single-phase electric motor that delivers a maximum pumping flow rate of 73 GPM (4,380 GPH) and a total dynamic head reach of 60 feet through a high-capacity 3-inch NPT male discharge port, this industrial dewatering unit incorporates a shaft-mounted built-in agitator to churn settled particulates into liquid suspension. Outfitted with an abrasion-resistant semi-vortex urethane rubber impeller, a rugged cast iron pump casing, dual silicon carbide mechanical shaft seals inside an isolated oil chamber, and patented Oil Lifter technology, it equips civil contractors, utility crews, and equipment rental operations with reliable, continuous slurry pumping across demanding jobsite environments.

Best Used For:

• Deep Excavation Pit and Shaft Dewatering: Evacuating high-volume groundwater, silt runoff, and drilling slurries from deep commercial foundation footings, caissons, and elevator shafts requiring up to 60 feet of total dynamic head lift.
• High-Flow Utility Vault and Stormwater Drainage: Clearing abrasive stormwater accumulation, sand, and gravel sediment rapidly from municipal utility vaults, retention ditches, and highway underpasses.
• Industrial Site Flooding and Sump Pumping: Draining flooded commercial basements, retention lagoons, settling ponds, and aggregate wash plants using high-capacity 3-inch discharge hose lines.

Key Performance & Safety Features

• Shaft-Mounted Built-In Agitator: Churns heavy settling sand, sludge, and dense mud into liquid suspension, ensuring continuous particulate flow without clogging the suction strainer.
• Semi-Vortex Urethane Impeller: Resists severe wear from abrasive solids and slurry, maintaining peak hydraulic pressure throughout extended continuous-duty cycles.
• Dual Inside Mechanical Seals: Premium silicon carbide seal faces enclosed within an oil chamber protect critical internal motor components against abrasive dry-running friction and pressure spikes.
• Patented Tsurumi Oil Lifter: Directs lubricating oil across upper and lower seal faces regardless of oil level or operating angle, preventing premature seal wear and extending service life.
• Continuous-Duty Motor with Thermal Protection: Air-filled 1 HP electric motor includes an internal thermal overload protector to eliminate motor overheating risks during non-stop pumping.
• Extra-Long 32-Foot Submersible Power Cable: Heavy-duty waterproof cable features epoxy anti-wicking block seals to prevent moisture ingress into the motor housing if the outer jacket is damaged.

What's Included

• (1) Tsurumi HS3.75S 1 HP 115V Submersible Trash Pump with Built-In Agitator

Technical Specifications

Pro-Tip: When lowering this pump into deep caissons or slurry sumps, always use dedicated nylon rigging attached to the built-in lifting handle rather than pulling or suspending the unit by its 32-foot electrical power cord; this protects the internal epoxy cable seal from strain damage.
