Westinghouse 12500 Peak Watt Dual Fuel
This dual-fuel generator offers 12,500 peak watts (gas) and up to 12 hours of run time from a 6.6-gallon tank. Remote electric start adds convenience for quickly restoring power to a well pump and essential circuits. It includes a CO sensor for safer operation in enclosed spaces and transfer-switch readiness, ensuring a clean switchover during outages. The rugged 457cc Westinghouse engine is designed for reliability and long service life.
Westinghouse 12500 Peak Watt Tri-Fuel
Designed to run on gas, propane, or natural gas, this 12,500-watt tri-fuel model provides flexible fueling options for long outages. Remote electric start makes it easy to bring online, and the unit includes transfer-switch readiness with multiple receptacles for household and RV connections. A digital hour meter helps monitor usage, and the cast-iron sleeve engine supports durability for repeated storm-season use.
Westinghouse 13500 Peak Watt Tri-Fuel
With 13,500 peak watts and a tri-fuel design, this generator supports larger well-pump loads and other critical circuits. It offers remote electric start and transfer-switch readiness. The engine is a heavy-duty 500cc Westinghouse 4-stroke OHV, featuring a cast-iron sleeve and automatic low-oil shutdown for protection. Long run times are supported by a sizeable fuel tank and efficient fuel usage across fuel types.
Westinghouse 6600 Watt
Offering 6,600 peak watts and 5,300 running watts, this unit provides a compact, more portable option for smaller well pumps or essential loads. The 4.7-gallon tank supports extended runtimes, and the electric push-button start with a remote key fob adds convenience. It includes multiple receptacles and a transfer switch-ready configuration, with safety-focused rubber-outlet covers and a CO sensor for added protection.
Buying Guide: Key Considerations For Well Pumps
- Power and load matching: Determine your well pump’s starting surge and running wattage. Choose a generator with a comfortable margin (20–40% above the peak load) to avoid overloading during startup.
- Fuel type and availability: Gasoline is common, but dual-fuel and tri-fuel models offer flexibility when one fuel type is scarce. Consider propane or natural gas for longer outages.
- Transfer switch readiness: A permanent transfer switch ensures safe, automatic or manual transfer of power from grid to generator, protecting your equipment and utilities.
- Run time and fuel capacity: Longer runtimes reduce refueling frequency. Look for larger tanks and efficiency features if you expect extended outages.
- Starting options: Electric start with a remote key fob can save time and effort, especially in harsh weather or cramped spaces.
- Engine durability and maintenance: Models with cast-iron sleeves and automatic low-oil shutdown offer better longevity and protection for sustained use.
- Safety features: CO shutdown, rubber outlet covers, and clear hour meters help monitor performance and prevent hazardous operation.
- Noise levels and footprint: If the generator will be placed near living areas, consider models designed for quieter operation and smaller footprints.
- Compatibility with pumps and electrical loads: Ensure the generator’s outlets and voltage configuration support your well pump and any essential circuits without overfiring.
