What Is a Submersible Dewatering Pump?
A submersible dewatering pump operates while submerged in the water being removed. The ST3050D uses a centrifugal impeller to move large volumes of water through its 3-inch discharge, making it suitable for construction sites, excavations, well casings, site drainage, flooded rooftops, and other water-removal applications.
264 GPM Flow Rate and 86-Foot Maximum Head
The ST3050D provides a maximum pumping capacity of 264 GPM and a maximum head of 86 feet. Its performance makes it suitable for moving substantial volumes of water through discharge hose and piping, with actual flow depending on discharge elevation, hose length, fittings, and overall system resistance.
Durable Impeller and Mechanical Seals
The ST3050D uses a cast-ductile-iron impeller for dependable pumping performance and incorporates double mechanical oil-filled seals for reliable internal protection. The pump also features a cast iron and steel motor housing designed to conduct heat away from the motor during operation.
230/460V Three-Phase Motor Operation
The ST3050D operates with a 5 HP, 230/460V three-phase, 60 Hz electric motor. The pump ships from the factory configured for 230V operation and can be switched to 460V for compatible installations. A control box is required for safe operation and provides protection functions including thermal and voltage overload protection.
Compact Construction for Dewatering Applications
The ST3050D features a compact steel and cast iron housing with a 10.2-inch diameter and 26.8-inch overall height. Its streamlined design allows the pump to fit into 10.2-inch pipes, while the 49.2-foot molded power cable provides extended reach for suitable installations. The pump has an operating weight of approximately 120 pounds.
High-Temperature Water Handling
The ST3050D is designed to pump liquids up to 104°F (40°C). Its 3-inch discharge and heavy-duty construction make it suitable for general dewatering and water-transfer applications involving construction sites, industrial areas, flooded rooftops, and other locations requiring reliable high-volume pumping.
Warranty
The Multiquip ST3050D has a 1 Year Warranty from the date of purchase. Hoses, float switches, and the CB200 control box carry separate three-month warranty periods. Refer to Multiquip's warranty terms for complete coverage, conditions, and exclusions.
