Parker E702984 Bladder Kit 5 Gallon

Product Description

The PARKER E702984 is a replacement bladder kit designed for use with bladder-type hydraulic accumulators. The bladder is the flexible, pressure-separating membrane inside a bladder accumulator that isolates the gas charge from the hydraulic fluid. When the bladder degrades, tears, or loses flexibility, system performance drops and the accumulator must be rebuilt or replaced. This kit provides the bladder assembly needed to restore a 5-gallon bladder accumulator to proper operating condition. Licensed hydraulic technicians and fluid power specialists are the primary installers for this type of component.

Bladder accumulators are used in hydraulic systems across industrial, mobile, and process-control applications. They perform functions including energy storage, pulsation dampening, shock absorption, and emergency power backup. A 5-gallon accumulator is common in mid-size hydraulic power units and press circuits. This kit is suited for field rebuild work or workshop overhaul of an existing Parker bladder accumulator with a 5-gallon tank capacity.

Key Features

• Designed specifically for bladder accumulator rebuild service
• Fits 5-gallon tank capacity bladder accumulator assemblies
• OEM-sourced kit from Parker, the original accumulator manufacturer
• Packaged as a single-unit kit, ready for one accumulator service

Compatibility

Designed for use with Parker bladder accumulators with a 5-gallon tank capacity. No additional compatible model numbers were specified in the product data. Verify the accumulator model and bladder material requirements before ordering.

Installation Notes

Bladder replacement should be performed by a qualified fluid power technician familiar with hydraulic accumulator service procedures. Before beginning, fully depressurize the hydraulic system and discharge the nitrogen gas precharge from the accumulator per the manufacturer service documentation. Follow applicable safety standards for hydraulic system work, including OSHA guidelines and any relevant industry codes. Do not reinstall the accumulator until the system has been inspected for the root cause of bladder failure.
