Pressure Tanks – Pressure Cells – Accumulators

Pressure Tanks, Pressure Cells, or Accumulators, whatever you call them, are ideally suited for a wide range of general applications including pump booster systems, thermal expansion, irrigation systems, and minimizing water-hammer.

In domestic water systems that use an accumulator tank, the air pressure setting inside the tank should typically be set to approximately 66% (or two-thirds) of the system’s working water pressure — usually based on the pump’s maximum pressure capability.

For example, if the pump can deliver 45m of head (about 450kPa), the accumulator should be precharged to around 30m (or 300kPa) when the system is depressurized. This ensures the tank stores an optimal volume of water and helps maintain steady pressure while minimizing pump cycling.
