SEAFLO 1.0 L (39 oz) Pressurized Accumulator Tank — Reduces Pump Cycling, NSF-Certified Bladder

The SEAFLO 1.0 L (39 oz) pressurized accumulator tank is a compact, NSF-tested bladder tank that reduces pump cycling and smooths water flow for marine, RV, and off-grid pressurized water systems.

This compact accumulator is built to sit inline with your fresh water system and absorb sudden pressure changes so pumps run less often and faucets deliver steadier flow. With an internal rubber bladder precharged at 10 PSI and rated to 125 PSI maximum, the tank is designed for mobile and harsh environments where space is limited but consistent water delivery matters. Tested to NSF/ANSI/CAN 61 & 372 and evaluated for NSF 24 and UL 778 standards, it’s intended for potable water systems in boats, RVs, and remote setups.

How does the SEAFLO accumulator reduce pump cycling?

The internal bladder stores a small reserve of pressurized water so the pump doesn't need to start for every faucet adjustment. This cuts the number of pump starts, reducing motor wear, lowering noise, and improving energy use—especially important on battery-powered or off-grid systems.

• Pre-charged 10 PSI rubber diaphragm prevents waterlogging.
• 1.0 L (33.8 oz) internal volume supplies short bursts of flow.
• Decreases frequent on/off cycles, prolonging pump life.
• Works with low-power pumps to improve efficiency.

Will the tank make water flow feel smoother at showers and faucets?

Yes—the bladder absorbs pressure spikes and dampens sudden drops, so shower heads and taps maintain steadier output. That means fewer surprises when toggling valves and better control over hot and cold mixing.

• Reduces pressure spikes that cause uneven spray or temperature swings.
• Improves user comfort in showers and sink usage.
• Helps deliver consistent flow to appliances like dishwashers.

What are the installation and maintenance requirements?

Installation is straightforward: connect the tank inline using the 1/2" MNPT inlet/outlet and mount in any orientation since the sealed bladder prevents waterlogging. No routine maintenance is required for the bladder, though periodic visual checks for physical damage and verifying the air pre-charge are recommended.

• 1/2" MNPT plumbing connection for easy integration.
• Standard automotive-style air valve for pressure checks.
• Mount vertically, horizontally, or inverted—universal mounting.
• Maintenance-free diaphragm; inspect occasionally and check pre-charge.

Is this tank safe for potable water and durable enough for marine use?

Yes—the materials and design have been evaluated to NSF standards for contact with drinking water, and the construction is engineered for demanding mobile environments. It balances corrosion resistance, pressure capability, and long-term reliability in salt-air or vibration-prone installations.

• Tested to NSF/ANSI/CAN 61 & 372 for potable water contact.
• Evaluated to NSF 24 and UL 778 for safety and performance.
• Rated up to 125 PSI (8.6 BAR) for heavy-duty systems.
• Durable materials suited for marine, RV, and off-grid conditions.

Who is this for: The SEAFLO 1.0 L accumulator tank is aimed at boat owners, RV travelers, vanlifers, and off-grid homeowners who need a compact, low-maintenance way to stabilize water flow and reduce pump wear. It’s a strong choice when space is limited but reliable, NSF-tested potable water performance and reduced pump cycling are priorities.
