RV Accumulator Tank 075L Maximum 125PSI 1/2MNPT Port Fitting RV Boat Travel Trailers Caravans Pump Accessories Product Features 1. Pressure Stabilization & Pulsation Control: This accumulator tank maintains a constant 10-125PSI pressure range, absorbing shocks from high water pressure to eliminate "poof" sounds when opening faucets. Its diaphragm design buffers pump surges, ensuring gentle water flow in RVs, boats, and caravans. By reducing pressure spikes, it prevents pipe leaks and extends the lifespan of connected pumps, making it essential for noisy or vibration-prone systems. 2. Pump Protection & Noise Reduction: Act as a guardian for your water pump! The tank stores pressurized water during peak usage, minimizing frequent pump starts and stops. This cuts operational noise by 50% and prevents wear from cycling, significantly prolonging pump life. Ideal for compact spaces like RVs and yachts where silent, efficient systems are critical. 3. Effortless Installation & Versatility: Pre-charged to 10PSI (0.7bar) at the factory, this accumulator installs in minutes. Simply adjust air pressure to 3PSI below your pumps switch point, connect via 1/2" MNPT threaded ports, and secure hoses with clamps. Compatible with SHURflo, Jabsco, and most 12V/24V pumps, it adapts seamlessly to RVs, marine vessels, and beverage dispensing systems. Product Specifications Item Type: Accumulator Tank Internal Volume: 0.75L (25 FL.OZ) Charging Pressure: 10 PSI (0.7 BAR) Max Operating Pressure: 125 PSI (8.6 BAR) Port Size: 1/2" Male NPT Air Valve: Standard automotive tire valve Dimensions: 7.9 x 5 x 4.5 in (20 x 12.7 x 11.4 cm) Material: Food-grade diaphragm & steel casing Function: Stabilizes pressure, reduces pump cycling, prevents water hammer Package List 1 x Accumulator Tank Body 2 x Wing Nut Fittings 1 x User Manual Installation & Usage Pre-Installation Check: Verify factory pre-charge (10PSI). Adjust air pressure to 3PSI below pumps start pressure using a tire gauge. Mounting: Install vertically near the water pump using brackets (not included). Ensure ports face downward for optimal air-water separation. Connection: Attach 1/2" MNPT port to the pumps outlet using wing nuts. Secure hoses with clamps. Operation: Upon startup, water fills the tank. When pressure peaks, the pump stops. As faucets open, the tank supplies water first. The pump reactivates only when tank pressure drops below its trigger point, reducing cycles by 30-70%. Compatibility Pumps: SHURflo 4000/5000 series, Jabsco Par-Max, SeaFlo, and all 12V/24V diaphragm pumps with 1/2" ports. Vehicles: RVs (Class A/C), travel trailers (Airstream, Jayco), caravans, boats (yachts, sailboats), and off-grid water systems. Systems: Cold/hot water lines, hydronic heating, beverage dispensing, and irrigation setups requiring pressure stabilization. Maintenance Guidelines Monthly Pressure Check: Use a tire gauge to ensure air pressure remains 3PSI below the pumps start pressure. Recharge if low. Annual Diaphragm Inspection: Drain the tank via the air valve. Check for membrane wear by pressing the valveif water leaks, replace the tank. Sediment Flushing: Every 6 months, disconnect the tank, flush with clean water, and wipe the exterior to prevent corrosion. Leak Detection: Apply soapy water to fittings if pump cycles abnormally. Tighten connections or replace seals immediately. : _x000D_
