NorthStar 3in Cast Iron Full Trash Pump (21000 GPH, Honda GX240, 1-1/4in Solids)

Description

NorthStar 3in Cast Iron Full Trash Pump (21,000 GPH, Honda GX240, 1-1/4in Solids)

The NorthStar 3-Inch Cast Iron Full Trash Pump is a heavy-duty contractor-grade self-priming trash water pump built for construction dewatering, flood control, agricultural drainage, and industrial water transfer applications. Powered by a dependable Honda GX240 OHV commercial engine, this high-performance pump delivers up to 21,000 GPH (350 GPM) while handling solids up to 1-1/4 inches, making it ideal for pumping muddy water, sludge, sand, leaves, sticks, and debris-filled liquids.

Designed for demanding jobsite conditions, the pump features a cast iron volute, high-chrome cast iron impeller, and a premium silicon carbide mechanical seal that provides exceptional resistance to wear, heat, and corrosion. A built-in check valve helps maintain prime between uses, while engine and pump isolation mounts reduce vibration for smoother operation and longer service life. The rugged steel roll cage protects the pump during transport and operation, making it a reliable choice for contractors, municipalities, utility crews, and emergency response teams requiring powerful portable pumping capability.

NorthStar 3in Cast Iron Full Trash Pump (21000 GPH, Honda GX240, 1-1/4in Solids): Buying Considerations

The NorthStar 3in Cast Iron Full Trash Pump features a Honda GX240 engine and delivers up to 21,000 GPH. With self-priming operation, cast iron construction, and the ability to handle solids up to 1-1/4 inches, it is ideal for construction dewatering, flood control, agricultural drainage, and industrial pumping applications.

Before ordering the NorthStar 3in Cast Iron Full Trash Pump (21000 GPH, Honda GX240, 1-1/4in Solids) from NorthStar, review the points below against your actual site conditions and workload. Published specifications describe the equipment under test conditions, and real-world performance depends on how closely your application matches those conditions. Buyers in the United States, Canada, and Asia should also confirm local voltage and frequency requirements, applicable safety or emissions standards, and freight or import logistics for the destination before finalizing an order.

What to Check Before You Buy

• Define required flow and total dynamic head at the discharge point – engine-driven pumps are commonly undersized when only flow rate is considered.
• Check suction lift, priming method, and maximum solids size the pump can handle without clogging.
• Verify fuel type and runtime requirements match the application, especially for extended dewatering or irrigation jobs.
• Confirm hose/fitting size matches the pump's rated port size to avoid unnecessary friction loss.

How much reserve capacity should an engine-driven pump have over the calculated requirement?

A reasonable margin accounts for pipe friction losses, fitting losses, and any future demand growth – undersizing based purely on a theoretical flow calculation without real-world losses is a common reason pumps underperform once installed.

For sizing help across the full Engine Driven Pumps category, compare specifications side by side before committing to a specific model, and confirm current pricing, availability, and freight details for your location. Keep the supplier data sheet and any acceptance criteria on record for future maintenance and replacement decisions.
