Bladder-Style Hydraulic Accumulators
Charge these accumulators to the pressure you need, and they will help a system maintain a constant pressure during pump failure. Mount accumulators within 25° of vertical. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.
Note: For safety, do not disassemble accumulators while they're under pressure.
Use a charging and gauging kit to increase or decrease an accumulator's charge.
