Pressurised Accumulator Tanks

Proceans sea-flow accumulator tanks hold a reservoir of air and water downstream (that is after the pump outflow) from the pump. The air acts as a cushion, absorbing pump and pressure fluctuations, smoothing the flow and making the system quieter. Accumulators allow the pump to reach shut-off pressure more smoothly which reduces the on/off cycle which gives better control of hot and cold water delivery.

If your modern pressure pump is over cycling it is recommended to install an inline pressurized accumulator tank to prevent battery drain and the annoyance of pump cycling noise and vibrations.

The SeaFlo accumulator tank must be fitted as close as possible to the discharge port of the pressurised water pump. When mounting it is preferable to have the inlet/outlet at the bottom of the tank

The accumulator tank acts as a pressure buffer, ensuring a smooth flow of water from the outlets. Without an accumulator tank, the pump is liable to cycle on and off rapidly whenever its flow rate exceeds the demand from your outlets. There are no adjustments available to these pressurized (with nitrogen) accumulator tanks

Constant on-off cycling leads to increased pump wear and unnecessary battery drain. The accumulator tank stops this rapid cycling, resulting in smooth water flow and an extended pump life.

Where do I fit an accumulator tank? The accumulator tank should be fitted in the discharge line from the pump, as close as possible to the pump itself (see diagram). The tank will serve no useful function if fitted in the pump inlet pipework.

The size of the accumulator tank depends on the number of outlets you will be using together at any given time.

The 750ml or 0.75 liter is ideal for one or 2 outlets being used at once, whilst the

The 1,000ml or 1.0 liter is ideal for more than 2 outlets being used at once.
