The KOSHIN STV-50X is a rugged 2" semi-trash centrifugal pump engineered for dewatering, irrigation, construction and general water transfer where debris and abrasive particles are present. It’s driven by a reliable Koshin K180 179cc engine (4.7 hp) built for long runtimes and low-vibration operation.

This portable water pump delivers up to approximately 163 GPM with a maximum discharge head near 90 ft and a suction lift around 26 ft — making it ideal for medium-duty dewatering, trench draining, and site cleanup.

• Inlet / Outlet: 2" (50 mm) NPT
• Engine: Koshin K180, 179 cc, reliable low-oil shutdown
• Max Flow: ≈163 GPM (≈580 L/min reported by regional listings)
• Max Head: ~90 ft (26 m); Max Suction Lift: ~26 ft (8 m)
• Designed for solids up to ~8 mm (semi-trash capability)

Durability features include silicon carbide (SiC) mechanical seals for enhanced abrasive resistance and longer service life, spheroidal graphite ductile iron impeller and volute for superior erosion resistance, and a die-cast aluminum housing for reduced weight and portability. These materials and seals reduce maintenance frequency on muddy or sandy sites.

The STV-50X is self-priming, housed in a powder-coated tubular roll cage for protection and easy transport, and optimized for low fuel consumption and quiet operation — attributes rental companies and contractors value for reliability and uptime. Typical use cases: construction dewatering, agricultural irrigation, flood response, pond draining, and municipal maintenance.
