Buying Guide: Important Considerations For 5.5 GPM Soft Wash Pumps
- Flow and pressure needs: Confirm that 5.5 GPM at 60 PSI meets your spraying or cleaning requirements. Higher PSI can improve cleaning but may demand sturdier hoses and fittings.
- Power source and electrical demand: 12V pumps are common for mobile use, while 110V pumps may suit stationary setups. Check amperage and gauge appropriate wiring and fuses.
- Self-priming and lift height: Self-priming to 8–10 feet is typical. Plan your pump placement relative to the water reservoir and intake height to avoid dry running.
- Durability and chemical resistance: Look for corrosion-resistant materials and a polymer or brass manifold if you expect exposure to bleach or strong cleaners.
- Automatic shut-off and pressure control: Pumps with automatic pressure switches help maintain steady flow and conserve energy, especially in intermittent use.
- Fittings compatibility: Ensure 1/2” MNPT or similar fittings match your hoses and spray guns. Consider adapters if your hardware uses different sizes.
- Prime efficiency and installation: Self-priming height, power cord length, and mounting base affect how quickly you can deploy a system and how secure it will be in vans, boats, or workshops.
