Pressure Tanks


PRESSURE TANKS
Orion supplies pre-pressurised diaphragm tanks which provide a closed drinking water system, reducing the risk of impurities entering the system. They are available in a number of sizes/capacity from 2 litres to 450 litres and are covered by a manufacturer’s warranty of 5 years.

The tanks are manufactured from steel with a high quality paint finish and have a stainless steel 25mm connection. The tank has a polypropylene liner to prevent water coming in contact with the steel tank and the diaphragm is constructed from a high grade butyl rubber compound.

There are many benefits of using a pressure tank with your pump, including –
  • less pump starts means less power used
  • less pump starts avoids short cycling causing burn-out, reduces wear and increases life of the pump
  • assists to absorb water hammer
  • greater reliability if unreliable power source/supply
  • some water available during power cuts (amount dependent on tank size)
Tanks are available in vertical and horizontal configurations in the following sizes/capacity (litres) -
2, 8, 18, 20, 35, 60, 80, 100, 170, 235, 300, 450

Each tank has a pre-charge of 28psi (1.9bar) with a maximum working pressure of 150psi (10 bar). When installing the tank with a pump with a mechanical pressure switch system, the air charge needs to be increased to be set at 3psi (20kPa) below the pump switch-on pressure. In an electronic system, the air charge should be set at 70% of the maximum pressure.
