Professional 10 HP Three-Phase 460V Stainless Steel 4-Inch Submersible Centrifugal Dewatering Pump
The Multiquip ST41460 is an industrial-grade 4-inch submersible centrifugal dewatering pump featuring a high-torque 10 HP three-phase 460V electric motor, engineered to execute high-volume fluid transfers across deep excavation fields, commercial utility stations, and municipal jobsites. Delivering a massive water capacity threshold of 423 GPM and an impressive 138 feet of total dynamic head lift, this heavy-duty unit easily passes spherical solids up to 0.6 inches through its dynamically balanced high-chrome steel impeller matrix. Built to survive highly abrasive environments, the architectural configuration incorporates a corrosion-resistant 304 stainless steel suction strainer, oil-filled double mechanical seals, and an internal heat-treated 410 stainless steel shaft to eliminate mechanical downtime during continuous-duty pumping cycles.

Best Used For:
- Municipal Well Dewatering: Clearing deep-well drainage collection grids and high-reach containment vaults for civil utility infrastructure setups.
- High-Volume Site Drainage: Extracting floodwaters and structural runoff carrying abrasive suspended solids out of large commercial foundation excavations.
- Industrial Fluid Routing: Moving high-temperature chemical process water ranging up to 140° F across closed treatment loops spanning a pH spectrum of 4 to 10.
Key Performance & Safety Features
- Industrial Three-Phase Drivetrain: Commercial 10 HP, 460V motor assembly optimizes energy consumption metrics during continuous high-load fluid displacement.
- Dynamic Semi-Open Impeller: High-chrome alloy steel cutter geometry resists wear while passing 0.6-inch spherical debris fields without clogging.
- Oil-Filled Dual Seal Protection: Advanced double mechanical seals form an impenetrable moisture barrier to isolate electric motor windings from fluid invasion.
- Rugged Stainless Steel Chassis: 304 stainless steel suction screen and casing frame reject chemical attack vectors and high-velocity silt pitting.
- Molded Heavy-Duty Power Cable: Integrated 33-foot power cord includes a vulcanized relief boot to prevent electrical grounding faults during deployment.
What's Included
- (1) Multiquip ST41460 4-Inch Submersible Centrifugal Pump Base

Pro-Tip: To protect the 10 HP three-phase electric motor from inductive phase imbalance damage, this system must always be paired with a dedicated control box housing thermal and voltage overload relays. Never pull or lower the 205-pound pump body by its electrical cord path; always anchor a structural stainless steel cable assembly to the lifting handle to prevent strain-relief casing fractures.
