The Seaflo 0.75L accumulator tank helps smooth water delivery from pressure-switch-controlled pumps in boat, caravan and other small water systems. An internal rubber bladder separates water from compressed air, which cushions pressure changes and supplies a small reserve between pump cycles. Fewer starts reduce wear from repeated starting and stopping, helping extend pump life, and can reduce electricity use and running costs.
Inlet: 1/2" male NPT thread.
Outlet: 1/2" male NPT thread.
The 0.75L rating is the internal vessel volume, not the usable water draw-off. The amount delivered before the pump restarts depends on the pump switch pressures and tank air charge.
The factory air pre-charge is 70 kPa (10 psi). Adjust the pre-charge to about 20 kPa (3 psi) below the pump switch cut-in pressure, following the tank instructions. The factory setting is not suitable for every pump.
Install on the pump’s discharge side. The tank can be mounted in any position; secure the mounting feet and support the pipework. Switch off the pump and release water pressure before disconnecting the tank or checking the air charge.
The air charge can be checked and adjusted through a standard automotive-style tyre valve. Check the air charge regularly as directed in the manual. Maximum operating pressure is 860 kPa (125 psi).
