The bladder accumulator is comprised of pressure resistant shell, elastic bladder, gas valve and fluid port (anti-extrusion) assembly. BUCCMA bladder accumulators are available in a wide range of sizes and pressure ratings, and are compatible with a wide range of fluids, temperatures and permeation requirements. Their design makes them compatible for both pulsation and oil storage.
Buccma Piston accumulator use a sealed piston / barrel arrangement to separate gas and fluid, giving it a long service life, compatibility with extreme ambient temperatures. Although Piston Accumulators leverage nitrogen’s compressibility to the fullest, they are not very sensitive to pulsations.
Buccma diaphragm accumulators are constructed by electron beam welding two hemispherical shells together, and a rubber diaphragm is set between these two halves to separate gas and fluid. The Diaphragm Accumulator has a light weight to volume ratio and can be used in harsh conditions. They are very sensitive, making them ideal for pulsation dampening, however their gas pre-charge is limited.
