Built for the jobs that chew up standard pumps, these heavy-duty trash pumps move water loaded with sand, solids, and debris while minimizing wear and reducing the risk of clogging. A shaft-mounted agitator continuously suspends settled solids, helping the pump maintain steady flow and consistent performance in demanding conditions like construction sites, dewatering, pits, and other dirty-water applications.

Engineered for long service life, the pump features a urethane semi-vortex impeller that combines excellent abrasion resistance with strong hydraulic performance, and a dual inside mechanical seal with silicon carbide (SiC) faces to help deliver maximum durability and extended run time. A patented Oil Lifter helps ensure reliable lubrication at the seal faces, while the V-ring seal design adds another layer of protection by shielding the mechanical seal from abrasive particles—critical when pumping gritty, debris-laden water.

For hands-off operation, the HSZ Series offers an automatic, float-operated version that starts and stops with changing water levels—ideal for unattended dewatering and sump applications where reliability and uptime matter.
