ElbiAC25 GPM - 25 Ltr Accumulator Pressure Vessel - 25 Ltr - 10 Bar.The ElbiAC25 GPM 25 Litre Accumulator Pressure Vessel - 25 Ltr - 10 bar. 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
Vessels are key to keeping water and heating systems safe, reliable, and running efficiently. They help manage pressure, protect components, and make sure everything works smoothly day after day. At Pumpify, we offer vessels from top manufacturers like Flamco, Mikrofill, Stuart Turner, and Zilmet, so you can pick the right option with confidence.
From classic pressure and expansion vessels that balance system pressure to smart heating vessels that adjust automatically, there’s a solution for every setup. Maybe a flow-through vessel to keep water moving and prevent stagnation is what you need, or a potable water vessel for safe drinking water storage and regulation suits your project better.
With Pumpify, it’s easy to find the right vessel, helping your projects run smoothly and efficiently, every time.
