SEAFLO 8L Water Accumulator Tank – SFAT-087-021-01
SEAFLO SFAT-087-021-01 8L Accumulator Tank 87PSI Marine RV
8L pre-pressurised water accumulator tank
The SEAFLO SFAT-087-021-01 is an 8 litre accumulator for pump-fed pressure-water systems. It stores a cushion of pressurised water, making outlet flow smoother, reducing rapid pump starting and absorbing pressure fluctuations or water-hammer shock when taps and valves open or close.
This listing is for the tank only; it does not include a pressure pump.
Key Features
- ✔ Motor yachts, sailing yachts, cruisers, houseboats and workboats with a compatible pressure-water pump.
- ✔ Motorhomes, caravans, remote cabins, solar-water and other closed water circuits operating within the tank rating.
- ✔ Useful where a larger stored volume is wanted to reduce pump cycling and provide steadier low-flow delivery.
- ✔ Compatible only when the pump cut-in/cut-out pressure, pre-charge, 3/4 in MNPT connection and fluid system are suitable.
- ✔ Not a fuel, oil, sewage or compressed-air storage tank.

Compatibility and installation checks
- Confirm the complete system's maximum pressure cannot exceed 87 PSI / 6 bar.
- Check the pump's cut-in pressure and set the air pre-charge according to the tank and pump-system instructions before commissioning.
- Use a compatible 3/4 in MNPT fitting and support the tank securely so plumbing does not carry its weight.
- Install an isolation/depressurisation method and leave access to the air valve and water connection.
- Isolate electrical power, close the water supply and fully depressurise before checking pre-charge or servicing.
- Package: one 8L accumulator tank. Pump, gauge, hose, adaptors, isolation valve and mounting hardware are separate unless pictured.
Questions & Answers
Does the tank include a pump?
No. It is an accumulator tank for use with a compatible pressure-water pump system.
What is the maximum pressure?
87 PSI / 6 bar. The system must not exceed this rating.
Why must the air pre-charge be checked?
Correct pre-charge is required for useful storage volume and stable pump operation; the setting must suit the pump cut-in pressure.
Will it fit any water pump?
No. Pressure, connection thread, pre-charge requirements, fluid compatibility and installation space must all match.
