The accumulator vessel is a device that fitted into a pressurised water system will provide system water at a pre-set sustained pressure. This product is manufactured by Elbi. Its most common application is to supply systems in which the main supply pressure is too low and a pump is fitted to boost the pressure to an acceptable level. As system demands take place the accumulator vessel will sustain system pressure by feeding additional water into the system at the required pressure. This process will limit the number of times the pump needs to start (pump hunting) in order that system pressure remains at the optimal level.

The Elbi AFV 500 Litre Vertical Accumulator Pressure Vessel- 500 Ltr - 8 bar. is a Pressure Vessel item.

The operating pressure of this is 8 bar.
