SEAFLO 53-Series DC Diaphragm Water Pump – 7.0 GPM, 60 PSI, 12V | Heavy-Duty, Self-Priming, Bypass with Pressure Switch, Continuous Duty

SEAFLO 53-Series DC Diaphragm Water Pump – 7.0 GPM, 60 PSI, 12V | Heavy-Duty, Self-Priming, Bypass with Pressure Switch, Continuous Duty

The SEAFLO 53-Series 12V DC Diaphragm Pump delivers high-volume freshwater flow for demanding marine, RV, agricultural, and industrial applications. Engineered with a heavy-duty motor and durable 5-chamber diaphragm assembly, this pump produces an impressive 7.0 GPM while maintaining up to 60 PSI of pressure. Its self-priming capability allows flexible installation above or below the water source, making it suitable for a wide range of system layouts. Designed for reliability and constant operation, the 53-Series features a built-in bypass and an automatic pressure switch that engages only when needed, reducing cycling and enabling smooth, consistent water delivery across multiple outlets. This makes it ideal for large boats, multi-fixture RVs, agricultural sprayers, washdown stations, and off-grid freshwater systems. The pump’s sealed design, corrosion-resistant materials, and thermal overload protection allow it to withstand harsh environments and extended run times. Installation is straightforward thanks to the quick-connect ports, vibration-dampening mounts, and compatibility with standard 12V DC systems. With a continuous-duty rating and rugged internal components, the 53-Series is built for operators who require high output, efficiency, and long-lasting performance under heavy load conditions.

Key Features

• High-volume 7.0 GPM output. Supports large freshwater systems with enough flow for multiple outlets operating at the same time, making it suitable for boats, RVs, farms, and off-grid systems.
• Heavy-duty continuous-duty motor. Built with a robust sealed motor, thermal protection, and durable internal components that withstand extended runtimes and harsh environmental conditions.
• Integrated bypass system. Reduces pump cycling and maintains smoother flow under varying demand levels, improving system stability and extending component life.
• Automatic 60 PSI pressure switch. Turns the pump on and off based on system pressure, delivering reliable on-demand performance without requiring an accumulator tank.
• Self-priming up to multiple feet. Allows flexible installation above the water tank and simplifies system design with reliable suction lift capability.
