• 【Heavy Duty 55-Series Performance】 The 55-Series is our heaviest-duty water pump, featuring a 5-chamber diaphragm that delivers a massive 5.5 GPM flow and 70 PSI pressure. Engineered for high-demand water systems, it can easily power multiple outlets at once with professional-grade reliability.
• 【Internal Bypass Technology】 Equipped with a built-in bypass valve, this pump significantly reduces rapid cycling (frequent on/off) and allows for smooth water flow even at low demand. No more noisy water hammer or pulsating flow—enjoy a residential-like shower experience in your RV.
• 【Quiet Operation & Robust Build】 Despite its high power, the pump features vibration-dampening rubber feet and an optimized motor for ultra-quiet operation. The heavy-duty motor is thermally protected, ensuring it stays cool under pressure for long-term, intensive use
• 【Self-Priming & Run-Dry Safe】 This self-priming pump can lift water up to 9.8 vertical feet and is capable of running dry without sustaining damage. The heavy-duty pressure switch is factory-set to 70 PSI but remains adjustable to suit your specific water system needs
• 【Versatile & Easy Set-up】 Standard 1/2" MNPT fittings ensure compatibility with most RV and Marine plumbing. It’s the ultimate water solution for RVs, camper vans, off-grid cabins, and boat washdown systems. Comes with a clear strainer to prevent debris from entering the pump
