Parker AD050A21T9A1 Diaphragm Accumulator 30 Lb 3045 Psi

Product Description

The PARKER AD050A21T9A1 is a hydrin diaphragm accumulator designed for hydraulic systems requiring reliable fluid energy storage and pressure management. Rated to 3,045 psi maximum working pressure with a 30-pound capacity, this accumulator uses a Hydrin elastomer diaphragm to separate the nitrogen charge from the hydraulic fluid. The unit stands 5.94 inches tall with a 4.2-inch diameter and connects via an SAE Number 8 female port thread. It is pre-charged with nitrogen and suited for applications demanding consistent pressure compensation, shock absorption, or emergency fluid supply. Licensed hydraulic system technicians and fluid power specialists handle installation in industrial and mobile hydraulic circuits.

This accumulator is applied in hydraulic circuits where pressure fluctuation control, pulsation dampening, or supplemental flow is required. With a maximum flow rate of 100 liters per minute (26 GPM), it handles moderate-to-high flow demand scenarios. The operating temperature range spans -40 degrees F to 176 degrees F, making it viable for both cold-environment mobile equipment and standard industrial machinery. The nitrogen charge is factory-installed, reducing field setup time. The compact form factor fits space-constrained system layouts where bladder or piston accumulators may not be practical.

Key Features

• 30-pound capacity with Hydrin diaphragm for chemical and temperature resistance
• Pre-charged with nitrogen — ready for system integration
• SAE Number 8 female port thread connection for standardized hydraulic plumbing
• Maximum flow rate of 100 liters per minute (26 GPM)
• Operating range of -40 degrees F to 176 degrees F suits varied ambient conditions

Compatibility

Designed for use with nitrogen-charged hydraulic systems. For Use With: Nitrogen. Consult system specifications to confirm port thread, pressure rating, and diaphragm material compatibility before installation.

Installation Notes

Installation should be performed by a qualified fluid power technician familiar with hydraulic accumulator safety procedures. Depressurize the hydraulic system and discharge the accumulator fully before any service or connection work. Verify the nitrogen pre-charge pressure matches system requirements using a calibrated accumulator charging kit before commissioning. Follow applicable hydraulic system safety standards and equipment manufacturer guidelines for accumulator mounting orientation and torque procedures.
