SEAFLO Accumulator Tank Water Pump Flow Control 125 PSI, 0.75 L | Smooth Flow & Reduced Pump Cycling

Overview

The SEAFLO Accumulator Tank is a compact flow-control solution designed for marine, RV, and off-grid water systems. It features a pre-charged internal bladder and a 0.75 liter (23.5 oz) core, delivering steady pressure and calmer water delivery across outlets. Built to handle demanding setups, this tank is a practical upgrade for addresses like pulsating faucets or inconsistent shower pressure.

Why it helps you choose SEAFLO

• Smoothed water flow: The internal bladder works with the system to minimize pressure pulsations, resulting in quieter operation and more predictable faucet and shower performance.
• Reduced pump cycling: By buffering water, the unit lowers the frequency of pump start-stop cycles, potentially lowering wear and tear and improving energy efficiency.
• Reliable, maintenance-friendly design: A pre-charged internal rubber diaphragm reduces ongoing upkeep while keeping performance steady over time.
• High-pressure durability: Rated for up to 125 PSI, it supports both high-demand and extended-use configurations without compromising performance.

Practical benefits for real-life setups

In an onboard marine galley or a compact RV bathroom, steady pressure helps keep hot water temperatures more consistent and reduces the feeling of hotspots or cold water surges. For off-grid systems reliant on limited battery power, fewer cycles can translate to improved overall efficiency while maintaining reliable water delivery for daily needs.

The quick-install design, with standard 1/2" MNPT connections, supports easy integration into existing plumbing or new builds. Its soft rubber mounts dampen vibration, contributing to a quieter, more comfortable living environment on board or in remote installations.

Who is it for?

Ideal for boats, RVs, or off-grid homes where compact, durable pressure buffering is valued. It is suitable for individuals seeking a maintainable solution that helps stabilize output across outlets without guaranteeing specific results.
