Key Features of the Multiquip ST2047
Thermal Overload Protection
An integrated thermal protector automatically shuts down the motor if operating temperatures become too high, preventing damage and extending motor life. The motor restarts automatically once cooled.
Nitrile Rubber over Steel Impeller
This composite construction minimizes wear from abrasive particles and ensures a long service life in demanding dewatering environments.
Oil-Filled Mechanical Seal
A dedicated oil chamber lubricates and cools the shaft seal, providing superior protection and reliability compared to standard seals.
Lightweight and Portable
Weighing only 33 lbs and equipped with a durable carrying handle, the ST2047 is easy to transport and position on any job site.
Performance Overview
The Multiquip ST2047 submersible pump offers a maximum flow of 87 GPM and a maximum head of 47 feet. As is typical for centrifugal pumps, the flow rate decreases as the lift height increases. For optimal performance, operate the pump within the 20–60 GPM range at a 40–20 ft head. Created for continuous use in clean water, the pump will deliver reliable service when operated upright and not allowed to run dry.
Common Applications
Construction Dewatering: Ideal for draining flooded construction sites, keeping your project on schedule.
Utility and Infrastructure: Perfect for emptying well casings, cofferdams, manholes, and transformer vaults.
Excavation Projects: Efficiently handles general dewatering for any excavation task.
Residential Use: Quickly drains swimming pools or other large bodies of water.
Important Use Notes
Requires a 115V, 60 Hz, single-phase power source.
Operate the pump upright. Use a platform to prevent it from sinking into soft mud or sand.
For water use only. Do not pump flammable liquids.
The motor has a thermal overload device. If the pump jams, disconnect power immediately to prevent motor burnout.
Connect to a compatible 2-inch discharge hose. Support the hose properly to avoid stress on the discharge port.
