Pascal WPB32GB Hydraulic Pressure Accumulator

Pascal WPB32GB Hydraulic Pressure Accumulator is a spring-type energy storage device used in industrial hydraulic systems to store and stabilize hydraulic energy by absorbing pressure fluctuations and compensating for fluid volume changes. It employs a spring-loaded plunger mechanism and is rated for operating pressures up to ~7 MPa (70 bar class) with mineral-based hydraulic oil (ISO VG32 or equivalent). The unit features a high-strength steel body with sealing elastomers and supports manifold or piping mounting (GB/GS/T configurations); oil capacity ranges approximately from 3.3 to 13 cm³ depending on sub-model configuration and a temperature range of 0°C to 70°C. Common applications include hydraulic power units, industrial clamping systems, machine tools, and automated manufacturing equipment where pressure stability and shock absorption are required; it is used to reduce pressure spikes, compensate for thermal expansion, and maintain steady system pressure during operation. Common replacements include Parker Olaer spring-loaded accumulators, Hydac small-volume bladder accumulators, and Bosch Rexroth mini hydraulic accumulators.
