The Stanley SM2151101 Hydraulic Submersible Pump is engineered for reliable and powerful dewatering performance in demanding municipal, utility, construction, and industrial applications. As part of Stanley’s SM21 series, this fully submersible hydraulic pump delivers up to 300 GPM (1135 LPM) at a 50-foot head, making it exceptionally effective for removing water from confined spaces, vaults, manholes, and similar environments.

Designed for ease of use and durability, the SM2151101 features a cast iron impeller positioned close to the base to maximize liquid removal, a 2½-inch discharge, and flush-face quick-disconnect couplers for fast hookup to hydraulic power units. Unlike engine-driven pumps, it requires no priming and can be run submerged or even dry without damage, reducing setup time and maintenance needs.

Ideal for utility crews, municipal maintenance teams, and construction professionals, the Stanley SM2151101 combines high flow capacity, rugged construction, and trusted hydraulic performance for dependable dewatering in challenging conditions.
