Description

Multiquip ST2037 2-Inch 1HP Electric Submersible Centrifugal Dewatering Pump

The Multiquip ST2037 2-Inch Electric Submersible Centrifugal Pump functions as a high-flow fluid evacuation unit engineered to transfer clean and silt-laden water out of flooded construction excavations, utility vaults, and mechanical pits. Driven by a 1 HP 115V single-phase electric motor drawing 6.9 running amps, this compact 31-lb. pump moves up to 73 GPM with a maximum head lift of 37 ft. and dewaters flat concrete surfaces down to 1/2 in. depths. Built with a rugged cast aluminum outer housing, dual mechanical oil-lubricated seals, and an elastomer-molded impeller, this dewatering equipment provides reliable liquid transfer for municipal crews, utility contractors, and facility maintenance teams operating in confined sites.

Best Used For:

  • Utility Pit & Vault Dewatering: Evacuating standing water down to 1/2 in. depths from narrow electrical vaults, manholes, and utility trenches prior to cable splicing or maintenance.
  • Jobsite Foundation & Excavation Drainage: Pumping accumulated groundwater and rainwater runoff out of concrete footings and foundation basements at rates up to 73 GPM.
  • Confined Space Flood Mitigation: Rapidly deploying a slim 7.4 in. diameter electric pump into restricted sump pits and drainage basins requiring continuous pumping up to 120°F.

Key Performance & Safety Features

  • 1 HP Thermal-Protected Electric Motor: UL and cUL listed 115V motor incorporates internal thermal overload protection to prevent stator burnout during high-load continuous pumping.
  • Dual Mechanical Shaft Seals: Oil-filled dual mechanical seal chamber isolates electrical motor windings from fluid intrusion to ensure long service life.
  • Neoprene Over Cast-Iron Impeller: Abrasion-resistant rubberized impeller absorbs grit and particulate impact without eroding or binding against the volute wall.
  • Cast Aluminum Outer Casing: High-strength lightweight cast aluminum housing dissipates heat efficiently while maintaining structural durability at just 31 lbs.
  • Flat-Surface Evacuation Capabilities: Engineered suction casing geometry lowers standing water levels down to a minimal 1/2 in. depth on level concrete floors.
  • Heavy-Duty Molded 25-Foot Cable: Industrial-grade power cord features integrated strain relief protection to withstand continuous pulling and rough jobsite handling.

Pro-Tip: Before lowering the ST2037 into heavily silted trenches or muddy foundation sumps, place the pump on top of a perforated bucket or solid masonry paver. Elevating the base screen 2 to 3 inches above loose sediment prevents the neoprene impeller from drawing in large slurry stones, maintaining optimal 73 GPM flow rates and extending internal seal life.
