SEAFLO 12V 56A Series 5.0 GPM Variable Speed Smart On-Demand Marine/RV 5-Chamber Diaphragm Pump

SEAFLO 12V 56A Series 5.0 GPM Variable Speed Smart On-Demand Marine/RV 5-Chamber Diaphragm Pump

The SEAFLO 56A Series 5.0 GPM Variable Speed Pump is designed for marine and RV freshwater systems that require consistent pressure, quiet operation, and reliable performance across multiple outlets. Its 5-chamber diaphragm and variable-speed controller work together to deliver smooth flow on demand, automatically adjusting motor speed as faucets or fixtures are opened and closed, eliminating pressure spikes and cycling. Built for freshwater systems in boats, RVs, cabins, and tiny homes, the 56A Series pump is fully self-priming up to 6 feet and capable of producing up to 70 PSI. The onboard intelligent controller replaces the need for an external pressure switch or accumulator tank, making installations simpler and reducing system noise. A thermally protected motor, corrosion-resistant construction, and vibration-dampening rubber mounts support long-term durability in demanding environments. This model includes quick-connect ports, an inlet strainer, and multiple fittings for straightforward installation. It is suitable for multi-fixture systems including sinks, showers, galley stations, transom washdowns, and general freshwater distribution. Designed for consistent performance, low maintenance, and reliable operation, it is an ideal upgrade for owners seeking a steady home-like water experience aboard or on the road.
