The Wacker Neuson PST3 is a high‑performance 3″ electric submersible trash pump engineered for fast, dependable dewatering on construction sites, utilities, municipalities, and agricultural operations. Built with a ductile iron housing, shaft‑mounted agitator, and semi‑vortex urethane impeller, the PST3 efficiently handles water containing sand, silt, and solids up to 6–7 mm without clogging.

Powered by a 0.75 kW single‑phase motor, the pump delivers up to 240 L/min (63.4 GPM) with a maximum head of 12 m (39.4 ft), making it ideal for trenches, pits, foundations, and emergency water removal. The silicon‑carbide double mechanical seals run in an oil‑filled chamber for long service life, while built‑in thermal overload protection prevents motor damage during heavy use.

Compact and portable, the PST3 includes a 10 m power cable, heavy‑duty strain relief, and rugged construction suited for Hawaiʻi contractors working in wet, abrasive environments.
