PARKER 11044400225 BLA-32L-D22-M25 Bladders

PARKER bladders are typically made of synthetic rubber materials, such as nitrile rubber. This material offers excellent oil resistance, fatigue resistance, and a certain degree of elastic deformation capability, enabling it to withstand repeated expansion and compression under system pressure.

Parker 11044400225 BLA-32L-D22-M25 bladder is a key flexible separation element in hydraulic accumulators, used to separate hydraulic oil from compressed gas (typically nitrogen). Its primary functions include storing energy, damping pulsations, compensating for leaks, and eliminating shocks in hydraulic systems.

Structural Design: The bladder is specifically shaped to optimize its deformation pattern during gas charging and oil discharge, thereby extending its service life. It features a gas valve at the top for pre-charging with nitrogen and a metal fitting at the bottom for sealed connection to the oil port of the accumulator shell.

Functional Role: As a consumable component, the bladder may deteriorate over time due to material aging, fatigue, or improper operation. Thus, it is a critical part that requires regular inspection and replacement during accumulator maintenance cycles.

When selecting or replacing this bladder, the following points must be verified:

Model Compatibility: Ensure the bladder model exactly matches the existing accumulator shell model, including volume, connection type, and bladder style.

Media Compatibility: Verify that the rubber material of the bladder is compatible with the type of hydraulic fluid used in the system.

Operating Parameters: Confirm that its operating pressure and temperature ranges meet system requirements.
