Ibaiondo 500-Liter Membrane Hydropneumatic Accumulator AMR-PLUS 1 1/2"

The Ibaiondo AMR-PLUS 500, reference 03500031, is a membrane hydropneumatic accumulator designed for use in water supply installations and pressure groups, including fire protection applications. With a useful volume of 500 liters and a maximum service pressure of 10 bar, this model stands out for its robustness, ease of maintenance, and compatibility with drinking water.

This accumulator is made of high-strength steel with an exterior finish in blue RAL-5012, and incorporates a replaceable membrane in accordance with the EN 13831 standard, facilitating maintenance tasks and prolonging the equipment's lifespan. The high-quality membrane is suitable for use with drinking water and allows for maintaining constant pressure in the system, reducing pump start cycles and increasing the efficiency of the hydraulic assembly.

It features a bottom threaded brass connection of 1 ½” and a top inspection cover equipped with a threaded sleeve R 1” GM, allowing access for internal inspection. The factory pre-charge is done with nitrogen at 3 bar, ensuring excellent pressure stability and lower permeability to oxygen.
