Wessel Hydropneumatic Tanks



There are several different functions that a hydro-pneumatic tank can perform.

  • In a booster pump application, it can provide water to the system during periods of a no flow shutdown of the booster pump or it can provide water to replace leak loads.
  • In a well water application, it can provide the desired volume of water required between the pump shut down pressure and the pump turn on pressure.
  • In a sprinkler or irrigation pump application, the tank may provide a cushion to maintain necessary pressure so the jockey pump will not short cycle.
  • In any case, the amount of water that the tank will be required to supply to the system during any given cycle is called the drawdown. Drawdown must first be determined to properly size the hydro-pneumatic tank.

    ASME certified tanks are built to the latest edition of the ASME (American Society of Mechanical Engineers) code. This code sets stringent standards on how pressure vessels are to be manufactured. If any one of the standards is not met, the vessels is not an ASME Code "U" stamped pressure vessel.
