Engine-Driven — Operates Without Utility Power
Engine-driven design provides pumping capacity at remote construction sites, emergency dewatering locations, and any application where utility power is unavailable or unreliable. Honda and Robin/Subaru engines provide proven reliability.
Trash Pump Design — Handles Large Solids
Large volute clearances and semi-open impeller pass rocks, sticks, leaves, and semi-solids that would destroy a standard centrifugal pump. Designed for construction site dewatering where the pumped fluid contains significant debris.
Self-Priming — Fast Deployment
Self-priming capability allows rapid deployment without suction line preparation. Fill the priming chamber once and the pump primes itself — critical for emergency dewatering where every minute of setup time has operational cost.
Cast Iron Construction — Field Durability
Cast iron volute and impeller withstand the abuse of construction site operation. Designed to be serviceable in the field — standard replacement impellers, mechanical seals, and wear rings are stocked by AMT distributors.
High Volume Capability
Engine-driven trash pumps deliver high flow rates at low head — the correct performance curve for fast-fill, fast-drain, and high-volume dewatering applications where moving large volumes quickly is the priority.
Portable Design
Compact, portable design with lifting handle for single-person transport. Engine and pump are close-coupled on a single base — no alignment required after transport or repositioning on the job site.
