What Is a Submersible Dewatering Pump?
A submersible dewatering pump operates while submerged in the water being removed. The ST41460 uses a centrifugal impeller to move large volumes of water through its 4-inch discharge, making it suitable for construction, industrial, utility, and municipal dewatering applications.
High-Volume 423 GPM Pumping
The ST41460 provides a maximum pumping capacity of 423 GPM and a maximum head of 138 feet. Its high-capacity design is suitable for moving substantial volumes of water from excavations, well casings, drainage areas, manholes, quarries, and other demanding locations.
Chrome Steel Impeller and Dual Mechanical Seals
The ST41460 uses a dynamically balanced chrome steel impeller designed for abrasion resistance and extended service life. Its oil-bathed dual silicon carbide mechanical seal system provides reliable protection for internal pump components, while the heat-treated 420J2 stainless steel mechanical shaft supports durability during demanding operation.
460V Three-Phase Motor and Control Box Operation
The ST41460 operates at 460V, three-phase, 60 Hz with a 10 HP motor. The pump has a 15.0-amp running current and requires a compatible control box for safe operation, including thermal, over-current, power spike, and short-circuit protection. The CB14A5663 control box also supports float-switch connections for automatic water-level control.
Durable Construction for Demanding Applications
The ST41460 features a rigid stainless steel outer casing with a cast iron inner casing, stainless steel hardware, and a stainless steel strainer base. Its narrow 12.48-inch diameter allows the pump to fit into pipes as small as 14 inches, while the 49.2-foot molded power cable provides extended reach for suitable installations.
Large Solid Handling Capacity
The ST41460 can pass spherical solids up to 0.6 inches (15.2 mm) in diameter, making it suitable for a variety of demanding dewatering applications. The pump is designed to handle liquids up to 104°F (40°C) and is not intended for pumping salt water or chemicals.
Warranty
The Multiquip ST41460 has a 1 Year Warranty from the date of purchase. Hoses, float switches, and the CB14A5663 control box carry separate three-month warranty periods. Refer to Multiquip's warranty terms for complete coverage, conditions, and exclusions.
