Buying Guide: Key Purchase Considerations
- Power source and installation: Determine whether you need 12V, 115V AC, or a dual-voltage unit. Consider whether your fueling area has easy access to electrical outlets or if you need a portable, battery-powered option.
- Material and durability: Cast-iron bodies are common for heavy use, but ensure compatibility with the fuels you store. Check for thermal overload protection for hot or extended operation.
- Flow rate and suitability: All models listed offer 20 GPM, which is well-suited for large equipment fills and fleet fueling. Confirm compatibility with your tank size and desired fill time.
- Mounting and fit: If you’re installing on stationary tanks, verify bung size and mounting requirements (2″ bung is common). For mobile setups, make sure the pump and hose lengths meet your needs.
- Fuel compatibility: Ensure the unit supports gasoline, diesel, ethanol blends, methanol blends, and biodiesel blends up to B20, as applicable to your operation.
- Safety and spill control: Look for features like thermal protection, anti-drip designs, and integrated safeties to minimize risk during fueling.
- Warranty and service: A longer warranty reduces total cost of ownership and signals manufacturer confidence in durability.
Overall, these 20 GPM pumps provide a range of power options, from compact 12V models for portable use to heavy-duty 115V units designed for stationary tank installations. Consider your fueling frequency, site conditions, and available power when selecting a model to ensure efficient, safe, and dependable operation.
