Parker AD100B21T9A1 Hydrin Diaphragm Accumulator

Product Description

The PARKER AD100B21T9A1 is a nitrogen-charged hydrin diaphragm accumulator designed for hydraulic system energy storage, shock absorption, and pressure surge dampening. Rated to a maximum working pressure of 3,045 psi and a 60-pound capacity, this accumulator is pre-charged and ready for installation. The hydrin diaphragm material offers strong resistance to petroleum-based hydraulic fluids and temperature extremes, operating reliably from -40 degrees F to 176 degrees F. Licensed hydraulic system technicians and fluid power specialists install this unit in industrial and mobile hydraulic circuits where pressure stabilization and flow compensation are required.

This accumulator suits hydraulic circuits in industrial machinery, mobile equipment, and process systems that demand stable pressure maintenance and energy recovery. The SAE 8 female port thread provides a standardized connection point compatible with common hydraulic plumbing configurations. With a maximum flow rate of 100 liters per minute (26 GPM), it handles moderate to high-demand hydraulic circuits. The unit ships as a single assembly and is appropriate for both new installations and field replacement applications in demanding hydraulic environments.

Installation Notes

Installation should be performed by a qualified fluid power technician familiar with hydraulic accumulator safety procedures. Depressurize and isolate the hydraulic circuit fully before removing or installing the accumulator, and discharge any stored hydraulic pressure and gas charge according to system safety protocols. Use calibrated nitrogen charging equipment to verify pre-charge pressure against system design specifications before returning the circuit to service. Never charge with oxygen or any gas other than nitrogen.
