This pump is capable of delivering an impressive flow rate of 2.5 gallons per minute (GPM) at 3100 pounds per square inch (PSI), making it an excellent choice for tackling tough grime, grease, and dirt.

The NorthStar Comet pump is a vertical shaft design, which means the shaft runs vertically within the pump housing. This design provides several benefits, including improved cooling, easier access for maintenance, and increased durability. The pump features a heavy-duty cast iron housing, which not only adds to its robustness but also helps dissipate heat generated during operation, ensuring long-lasting performance.

The pump utilizes a reliable and proven Honda GC190 engine to power its operation. This 196cc, single-cylinder, overhead cam (OHC) engine delivers ample power while maintaining excellent fuel efficiency and low emissions. The engine is easy to start, thanks to its convenient recoil starter, and features full pressure lubrication to ensure the pump and engine components remain well-lubricated for optimal performance and longevity.

The NorthStar Comet pump comes equipped with several key features designed to make your pressure washing experience more convenient and hassle-free. These include an easy-to-access oil filter, large fuel tank, and an adjustable unloader valve, which allows you to fine-tune the pump's pressure output to suit your specific cleaning needs.

Additionally, the pump features an industrial-grade 3/8 inch inlet and outlet, ensuring a secure and reliable connection to your pressure washer hose. The pump also includes a conveniently located drain plug, which makes it easy to drain the pump after use, helping to prevent damage from standing water and ensuring the pump is ready for the next cleaning task.

In summary, the NorthStar Comet Pressure Washer Pump 3100 (model number 3970555) is a versatile and powerful gas-powered pressure washer pump, capable of delivering 2.5 GPM at 3100 PSI, and featuring a reliable Honda GC190 engine.
