Koshin Gasoline Water Pump, 3 Inch, 4.8HP Honda GX160 Engine - SEH80X

Koshin 3-Inch Gasoline Water Pump

The Koshin SEH-80X is a highly mobile 3-inch self-priming centrifugal water pump engineered specifically for rapid dewatering and agricultural irrigation where portability is essential. Weighing strictly 30 kg, this lightweight unit allows for effortless transportation across uneven terrain and tight job sites. It is powered by the highly reliable 4.8HP Honda GX160 four-stroke engine, which efficiently drives up to 930 liters of water per minute through its 80mm ports, making quick work of draining flooded trenches, filling tanks, or supplying remote fields without delay.

The mechanical resilience of this Centrifugal Pump ensures consistent, heavy-duty performance in harsh environments. While the outer casing utilizes die-cast aluminum to shed unnecessary weight and completely resist corrosion, the internal volute and impeller are forged from heavy-duty cast iron. This structural design guarantees that the internal mechanics will not degrade when pulling abrasive silts and small debris (up to 3mm). Supported by a carbon ceramic mechanical seal to eliminate leaks and Honda’s automatic Oil Alert shutdown system, this pump delivers hours of continuous operation with minimal maintenance required.

Key Features & Benefits:

• Powerful Honda GX160 Engine: Delivers a 4.8HP output with an Overhead Valve (OHV) 4-stroke design for optimal fuel efficiency, trusted reliability, and easy starting in all conditions.

• High Flow Capacity (3-Inch Ports): Large 80mm (3") suction and discharge connections allow for incredibly fast water movement, reaching a maximum flow rate of 930 liters per minute.

• Exceptional Pumping Reach: Offers a total head lift of up to 26 meters to push water across long distances or heights, paired with a maximum suction lift capacity of 7 meters.

• 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 and suspended solids.

• Corrosion-Resistant Housing: The exterior pump casing is manufactured from a die-cast aluminum alloy, making it highly resistant to rust, temperature fluctuations, and physical deformation while keeping the unit lightweight.

• Advanced Silicon Carbon Seal: Equipped with a highly durable mechanical seal crafted from special carbon ceramics to completely prevent leaks and provide extra wear durability.

• Smart Self-Priming Design: Once initially filled with water, the intelligent casing retains liquid and automatically purges air to start pulling water quickly upon startup without continuous manual priming.

• Automatic Engine Protection: Features the Honda Oil Alert system, an automatic shutdown mechanism that completely stops the engine if oil levels drop too low, preventing severe internal damage.

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

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