Key Features of the Multiquip ST2037

Internal Thermal Overload Protection

Prevents motor burnout by shutting down operation if temperatures exceed safe limits, ensuring the longevity of the Multiquip ST2037.

Dual Shaft Seals

Reliable double mechanical oil-filled seals provide superior leak protection, separating the pump section from the motor for extended durability.

Cast Aluminum Housing

The rugged housing offers excellent resistance to wear and corrosion while keeping the unit lightweight enough for single-person transport.

Neoprene Rubber Impeller

The impeller is constructed of Neoprene rubber over cast iron, minimizing wear and prolonging service life during general dewatering tasks.

Heat-Conducting Motor Casing

The cast iron/steel motor casing acts as a heat conductor, allowing the pump to handle liquids up to 120°F efficiently.

Performance Overview

The ST2037 provides a balance of flow and lift, offering a maximum head of 37 feet and a peak capacity of 73 GPM. It is designed for intermittent or continuous duty in clean water applications, capable of dewatering flat surfaces down to 1/2-inch levels. While not a high-pressure submersible pump, it delivers consistent volume for standard drainage needs. Best performance is achieved with short discharge hoses and minimal elevation changes.

Applications

• Draining swimming pools
• Clearing well casings
• Construction site dewatering
• Cofferdams and manholes
• Transformer vaults
• Excavation drainage
• Basement sump pits

Common Use

• General water transfer
• Emergency flood relief
• Utility maintenance

Installation & Operation Guidelines

• Water Only: This unit is a dewatering pump designed for water; it has a solids handling capacity of 0 inches. For trash applications, consider the Multiquip ST2010TCUL 2" High Capacity Trash Pump.
• Positioning: Always operate the pump in an upright position on a stable platform to prevent burrowing into mud or sand.
• Solids Handling: Do not use where heavy mud, grit, or silt is present without a platform or additional screening.
• Power Requirements: Requires a 115V, single-phase power source with a grounded receptacle.
• Manual Operation: The standard ST2037 is a manual pump; automatic operation requires the addition of a float switch or specific control box configuration.
• Low Water Levels: For surfaces requiring drainage down to 1/16", the Multiquip ST2038P Puddle Sucker may be a better fit.

Accessories & Add-Ons

• Discharge Hose: Pair with a 2-inch layflat hose for water disposal. View Hose and Fittings Collection.
• Float Switches: Optional tethered float switches (like Model SW-1 or SW-2) enable unattended automatic operation.
• Camlock Fittings: Standard 2" camlock connectors allow for quick and secure hose connections.
