Buying Guide: Key Considerations For Gas Powered Well Pumps
- What will you pump: Clean water vs. debris-laden water? Choose debris-tolerant semi-trash or trash pumps for dirty water.
- Flow rate vs. head: Higher GPM is useful for bulk transfers, while greater head (lift) is important for draining distant or elevated areas.
- Engine power and durability: Commercial-grade engines offer longer life in tough conditions; lighter units are easier to transport.
- Solids handling: If solids are present, verify the maximum particle size (in inches) the pump can pass without clogging.
- Portability: Consider weight, transport wheels, and handles for frequent site-to-site movement.
- Included accessories: Hoses, adapters, and fittings add value; ensure compatibility with your hoses.
- Maintenance: Look for accessible spark plugs, filters, and simple oil shutoff features for safety and longevity.
- Fuel considerations: Ensure fuel availability, storage safety, and proper refueling practices on-site.
Frequently Asked Questions
- What is the difference between a trash pump and a semi-trash pump?
– A semi-trash pump handles some solids, while a trash pump is built to handle larger debris more effectively. - How much water can these pumps transfer per minute?
– Most models listed range from about 79 GPM to 164 GPM, depending on the engine and impeller design. - Can these pumps run continuously on a construction site?
– They are designed for demanding use, but check engine specifications, fuel availability, and maintenance needs for extended operation. - What size hoses should I use?
