Bladders

HIDRACAR rubber bladders are 100% gas impermeable and are made in just one piece, without glued parts.

Available for all of our accumulator / pulsation dampener sizes, in all of our standard rubber materials: EPDM, FKM, NBR, butyl or silicone; as well as in other less usual materials like 70% fluor FKM, HNBR, low temperature NBR, Neoprene, Aflas, Hypalon,…

All bladders are fitted with a self-centering anti-extrusion (by the action of the gas charge pressure) button insert that prevents high stress from building up in the rubber.

The button inserts are made in the same material as the accumulator / dampener body (stainless steel, carbon steel, PVC, polypropylene, PVDF, etc…) the bladder is bound, and in the design for the corresponding pressure range (standard or high pressure).

For replacing the bladder, we recommend to use our tool for a quick extraction of the bladder from accumulators.
