Jabsco 52530-1000 Double Stack Water Pump System 9 GPM

The Jabsco 52530-1000 Double Stack Water System is a high-performance marine water pressure system designed for vessels requiring multiple water outlets. This professional-grade system delivers an impressive 9 GPM (34 LPM) flow rate, capable of servicing up to 7 outlets simultaneously with consistent pressure and smooth operation.

The innovative double stack design combines two self-priming pumps mounted on a pre-pressurized accumulator tank with an internal bladder. This configuration minimizes pump cycling, reduces noise, and provides smooth, even water flow throughout your vessel's plumbing system. The two-stage operation ensures one or both pumps activate as needed based on demand, optimizing efficiency and extending pump life.

Key Features:

• High flow capacity of 9 GPM (34 liters per minute) supports up to 7 outlets
• Dual pump configuration with pre-pressurized accumulator tank for consistent pressure
• Self-priming capability up to 6-10 feet of vertical lift
• Run-dry protection prevents damage during low water conditions
• Two-stage operation activates pumps based on water demand
• Internal bladder accumulator tank smooths flow and reduces cycling
• Thermal overload protection on both pumps
• ISO 8846 Marine compliant ignition protection for safe installation
• 3/4 inch hose tail connections for easy integration

Ideal for larger boats, yachts, and marine vessels with multiple heads, galleys, and washdown stations, this double stack system provides the reliability and performance demanded by serious boaters. The run-dry ability and thermal protection ensure long service life even in demanding conditions.
