Koshin Gasoline Water Pump, 4 Inch, 8HP Honda GX240 Engine, Made In Japan - SEH100X

Gasoline Water Pump 4 Inch

The Koshin SEH-100X is a professional-grade 4-inch self-priming centrifugal water pump engineered to handle high-capacity water transfer across demanding agricultural, domestic, and construction environments. Powered by a dependable 8HP Honda GX240 four-stroke engine, this unit easily manages clear water applications, making it highly effective for watering large gardens, draining construction trenches, pumping well water, and performing critical fire-fighting tasks. With an exceptional flow rate reaching up to 1,450 liters per minute, operators can move massive volumes of liquid rapidly and efficiently.

Built to withstand the rigors of heavy industrial and field use, the SEH-100X combines a lightweight, corrosion-resistant die-cast aluminum casing with heavy-duty cast iron impellers and volutes. This structural pairing ensures the pump handles abrasive silts without compromising operational longevity. A highly effective silicon carbon mechanical seal actively prevents leaks and resists long-term wear, while the integrated anti-vibration system, utilizing straight engine rubber mounts, significantly reduces mechanical stress on the entire unit. Protected by a sturdy steel rollover pipe frame, this pump guarantees reliable, continuous performance and easy transport across any rugged job site.

Key Features & Benefits:

• Powerful Honda GX240 Engine: Delivers an 8HP output with an Overhead Valve (OHV) 4-stroke design for optimal fuel efficiency, trusted reliability, and easy starting in all conditions via automatic decompression.

• Massive 4-Inch Flow Capacity: Large 100mm (4") suction and discharge ports enable a maximum flow rate of 1,450 liters per minute for rapid fluid transfer.

• High Total Head & Suction: Offers a total head lift of up to 28 meters (91 feet) to push water across long distances, paired with an 8-meter maximum suction lift.

• Heavy-Duty Cast Iron Core: Features a rugged cast-iron impeller and volute, providing superior durability and long-life performance even when pumping abrasive silts.

• Corrosion-Resistant Housing: The exterior pump casing is made of die-cast aluminum alloy, making it highly resistant to rust, temperature fluctuations, and physical deformation while keeping it portable.

• Specialized Silicon Carbon Seal: Equipped with a highly durable mechanical seal crafted from special carbon ceramics to completely prevent leaks and resist extreme wear.

• Automatic Engine Protection: Features the Honda Oil Alert system, which automatically shuts down the engine if oil levels drop too low to prevent severe internal damage.

• Self-Priming Convenience: The intelligent design retains water within the casing, allowing it to quickly pull water upon startup without requiring continuous manual priming.

• Anti-Vibration System: Engineered with straight engine rubber mounts that absorb impact and significantly reduce mechanical stress and wear on the unit during operation.

• Sturdy Rollover Pipe Frame: The entire unit is safely housed within a protective, full-wrap steel tubular frame, ensuring high structural stability and easy transport on tough job sites.

• Extended Operational Time: Includes an approximate 5-liter fuel tank capacity that supports up to 2 hours and 30 minutes of continuous pumping operation.
