Elbi - AFV 200 Ltr Vertical Accumulator Pressure Vessel - 200 Ltr - 10 Bar. - OBSOLETEThe Elbi AFV 200 Litre Vertical Accumulator Pressure Vessel - 200 Ltr - 10 bar. - Obsolete is a Pressure Vessel item. This product is manufactured by Elbi.
The accumulator vessel is a device that fitted into a pressurised water system will provide system water at a pre-set sustained pressure.
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 operating pressure of this is 10 bar.

Vessels
Pressure vessels and expansion vessels play a big role in keeping systems safe and balanced. Expansion vessels are commonly used in heating and hot water setups, where they absorb the natural rise in water volume as it heats. This keeps pressure under control, reduces the chance of leaks, and protects boilers, pumps, and pipework from damage.
Pressure vessels are found in pressurised water systems, including potable water supplies. By storing water under pressure, they cut down on pump cycling, extend system life, and deliver a steadier, more reliable flow.
At Pumpify, you’ll find both pressure and expansion vessels in a variety of sizes and specifications, so it’s simple to choose the right fit for your project.
