Parker AD200B25T9A1 Diaphragm Accumulator 120 Lb 3620 Psi

Product Description

The PARKER AD200B25T9A1 is a hydrin diaphragm accumulator designed for hydraulic systems requiring reliable energy storage, pulsation dampening, and fluid surge control. Rated to a maximum working pressure of 3,620 psi and a 120-pound capacity, it handles demanding industrial and mobile hydraulic applications. The hydrin diaphragm material provides strong resistance to petroleum-based fluids and a wide operating temperature range. Standing 9.88 inches tall with a 6.14-inch diameter, this accumulator ships pre-charged with nitrogen and connects via an SAE 8 female port thread. Licensed hydraulic system technicians and mechanical contractors are the typical installers.

This accumulator is suited for industrial hydraulic circuits, mobile equipment, and fluid power systems where pressure maintenance, shock absorption, and flow compensation are required. It supports a maximum flow rate of 160 liters per minute (42 GPM), making it appropriate for medium-to-high flow hydraulic circuits. Operating temperature range spans -40 degrees F to 176 degrees F, covering both cold-start and elevated-temperature service environments. The nitrogen pre-charge is factory-set; field pre-charge adjustment may be needed to match system design pressure.

Key Features

• 3,620 psi maximum working pressure for high-pressure hydraulic circuit compatibility
• Hydrin diaphragm construction for petroleum-fluid resistance and long service life
• Factory pre-charged with nitrogen — ready for installation and final system pre-charge setup
• SAE 8 female port thread for standard hydraulic line connection
• Maximum flow rate of 160 liters per minute (42 GPM)
• Wide temperature range: -40 degrees F to 176 degrees F

Compatibility

Designed as an OEM-style replacement or new-installation component for hydraulic systems using nitrogen-charged diaphragm accumulators with SAE 8 female port connections operating within the stated pressure and temperature ratings.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power systems and applicable safety codes. Depressurize and bleed the hydraulic circuit completely before removing or installing any accumulator. Verify that the nitrogen pre-charge pressure matches the system design specification before pressurizing the hydraulic side. Never use oxygen or any gas other than nitrogen for pre-charging a hydraulic accumulator.
