Parker AD280A25T9A1 Hydrin Diaphragm Accumulator

Product Description

The PARKER AD280A25T9A1 is a pre-charged hydrin diaphragm accumulator designed for hydraulic system energy storage, pulsation dampening, and shock absorption. It handles a maximum working pressure of 3,620 psi and carries a capacity of 170 lb. The unit stands 10.47 inches high with a diameter of 6.63 inches and ships pre-charged with nitrogen. An SAE number 8 female port thread provides the hydraulic connection. Licensed hydraulic system technicians and industrial maintenance professionals are the primary installers of this component.

This accumulator is suited for mobile and industrial hydraulic circuits where pressure fluctuation control, emergency power reserve, or thermal expansion compensation is required. It operates across a temperature range of -40 degrees F to 176 degrees F, making it viable for both outdoor mobile equipment and indoor industrial installations. The maximum flow rate is 160 liters per minute (42 GPM). The hydrin diaphragm construction resists petroleum-based fluids commonly found in these circuits.

Key Features

• Pre-charged with nitrogen for immediate service readiness
• Hydrin diaphragm material provides resistance to petroleum-based hydraulic fluids
• 3,620 psi maximum working pressure suits high-demand hydraulic circuits
• SAE number 8 female port thread for standard hydraulic plumbing connections
• Wide operating temperature range of -40 degrees F to 176 degrees F
• Maximum flow rate of 160 liters per minute (42 GPM)

Compatibility

Designed as an OEM-style replacement or new-installation diaphragm accumulator for hydraulic systems requiring an SAE number 8 port connection and a maximum working pressure of 3,620 psi.

Installation Notes

Installation should be performed by a qualified hydraulic systems technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any accumulator. Verify that the pre-charge nitrogen pressure matches system requirements before commissioning. Do not use gas other than nitrogen for charging, and do not exceed the rated maximum working pressure.
