SEAFLO Accumulator Tank Water System 0.75L (23.5 oz) Red — 125 PSI, Internal Bladder for Reduced Pump Cycling

SEAFLO's 0.75 L (23.5 oz) accumulator tank with an internal bladder reduces pump cycling and evens out water flow for quieter, more efficient marine, RV, and off-grid water systems.

This compact accumulator tank (model SFAT-075-125-01) is a pre-pressurized vessel that cushions pressure changes, providing steadier water delivery and fewer pump starts. Built to withstand up to 125 PSI, the unit uses a bonded rubber diaphragm to separate the air charge from the water, eliminating routine maintenance and simplifying installation. It connects with standard 1/2" MNPT fittings and mounts with vibration-damping hardware, making it practical for tight spaces aboard boats, in RVs, or at remote installations.

How does this accumulator tank reduce pump cycling and why does that matter?

The bladder absorbs short pressure spikes and supplies a small volume of water so the pump doesn't need to start for every faucet or spray. Fewer starts mean less wear on the pump, lower electricity or battery draw, and longer equipment life.

• Pre-charged 10 PSI air cushion for immediate pressure response.
• 0.75-liter internal volume supplies water during brief demands.
• Compatible with typical 1/2" MNPT pump systems for quick retrofit.

Will the tank make my water flow feel more consistent?

Yes — the internal bladder evens out pulses from reciprocating pumps so faucets and showers run with steadier pressure. This reduces water hammer and gives a smoother user experience without expensive system changes.

• Eliminates short pressure spikes and water pulses at outlets.
• Supports stable hot-water temperature by maintaining pressure during use.
• Soft mounting reduces vibration and audible pump noise.

Is installation difficult and what connections are required?

Installation is straightforward: the tank uses standard 1/2" male NPT inlet/outlet threads and can be mounted using the supplied hole pattern. No bladder servicing is required because the rubber diaphragm is factory pre-charged and sealed.

• 1/2" MNPT inlet/outlet for common plumbing compatibility.
• Mounting hole spacing: 4-1/8" center-to-center for secure attachment.
• Overall dimensions: 7-7/8" long × 5" wide × 4-1/2" tall for compact fits.

What performance and specification details should I know?

The tank is rated for high-pressure applications and light enough for mobile use. Its spec sheet lists a maximum working pressure of 125 PSI and a pre-charge of 10 PSI to match typical pump controls and pressure switches.

• Model: SFAT-075-125-01 — internal volume 0.75 L (23.5 oz).
• Maximum pressure: 125 PSI (8.6 BAR); pre-charge: 10 PSI (0.7 BAR).
• Flow capability listed up to 125 GPM; weight approximately 1 lb.

Who this is for: boat owners, RV enthusiasts, and off-grid system installers who want a compact, maintenance-free way to reduce pump cycling, cut energy use, and smooth water delivery. The SEAFLO accumulator tank is ideal when space is limited but consistent pressure, quieter operation, and longer pump life are priorities.
