Multiquip ST2040T 2-Inch 1 HP Electric Submersible Trash Pump
The Multiquip ST2040T 2-Inch 1 HP Electric Submersible Trash Pump is a continuous-duty dewatering workhorse engineered for evacuating muddy silt, slurry, and debris-laden runoff from flooded excavations, utility vaults, and construction trenches. Driven by a dependable 115V single-phase 1.0 HP electric motor delivering up to 79 GPM and a 40-foot total dynamic head, this portable 34-pound pump handles spherical solids up to 1 inch in diameter without binding.
Built for severe commercial use, the ST2040T pairs a heavy-duty cast iron casing with an abrasion-resistant, neoprene-rubber coated cast iron vortex impeller that withstands scouring from sand and gravel. An integrated internal thermal overload sensor protects against dry-run heat buildup, while the 25-foot heavy-duty power cord features molded strain relief for continuous, trouble-free submersion across municipal, industrial, and contractor job sites.
Recommended Jobsite Applications
- Excavation & Footing Dewatering: Rapid evacuation of standing rainwater, ground slurry, and abrasive grit from foundation pits.
- Manhole & Utility Vault Drainage: Clearing underground telecommunications, electrical, and plumbing access vaults before crew entry.
- Emergency Commercial Flood Mitigation: High-capacity pump-down of flooded elevator shafts, basements, and low-lying commercial job floors.
Key Performance & Safety Features
- 1.0 HP Commercial Electric Motor: UL/CUL-listed continuous-duty single-phase motor with integrated thermal overload shutdown protection.
- 79 GPM High-Flow Capacity: Moves up to 4,740 gallons per hour with a maximum total dynamic head of 40 feet (17.3 PSI).
- 1-Inch Spherical Solid Clearance: Wide-clearance vortex flow path easily clears gravel, mud, sludge, and fibrous debris without volute clogging.
- Cast Iron & Neoprene Construction: Heavy cast iron casing absorbs impacts, while the rubber-coated impeller resists abrasive wear from high-velocity silt.
- 25-Foot Molded Cord: Heavy-gauge water-resistant cord features industrial molded strain relief for safe handling on active jobsites.
- Low Drawdown Clearance: Capable of pumping standing surface water levels down to 2 inches on hard, level concrete or rock beds.

💡 FIELD PLACEMENT PRO-TIP: In loose muck or deep silt trenches, elevate the pump slightly on a solid CMU concrete block or suspend it from the handle using a safety cable. Submerging the base directly into thick mud beds will starve the bottom intake, reduce discharge volume, and cause unnecessary thermal cycling.
Frequently Asked Questions: Multiquip ST2040T
A: No. The ST2040T is a continuous-run manual dewatering unit. For automated liquid-level cycling, choose the Multiquip ST2040TF model, which includes a factory-wired mechanical tethered float switch.
A: The ST2040T features an open cast iron vortex impeller with neoprene coating that safely passes spherical solids, sand, and muddy sludge up to 1.0 inch (25.4 mm) in diameter without clogging.
A: It operates on a standard 115V single-phase 60 Hz outlet, drawing 6.8 continuous running amps with a 34.0 amp starting inrush. It should be connected to a dedicated 15A or 20A GFCI-protected circuit.
A: The pump is equipped with a 2-inch female NPT threaded discharge connection, compatible with standard 2-inch male NPT hose nipples, cam-and-groove quick disconnects, and blue layflat discharge hose.
