How Do Parker Bladder Accumulators Work - Tutorial

This video is a tutorial with animation on how bladder accumulators work.

Parker is the leading manufacturer of bladder accumulators in North America. Parker's bladder style accumulator is a proven design that has served both the industrial and mobile hydraulic markets, providing energy management solutions for many hydraulic system applications. Offering a standard, globally certified bladder accumulator (ASME and CE rated) is Parker’s approach at one accumulator design certified for most markets, geographies and applications.

This animated video shows the basic concepts of operation for bladder accumulators. The bottom repairable design, due to its simplicity and cost effectiveness, has become the de facto “Industry Standard” bladder accumulator. Sizes range from 10 cu in to 15 gallons. Parker also offers a top repairable design, which permits easy checking and maintenance of the bladder without removing the accumulator from the service line. Sizes range from 2.5 gallons to 15 gallons.

Bladder accumulators are typically found in industrial and mobile applications requiring energy management. Typical applications include:

• Supplemental flow
• Emergency power
• Shock absorption
• Noise Attenuation
• Ride Control/Suspension

Advantages to Bladder accumulators include:

• Highly tolerant of fluid contamination
• Very quick response time
• Works well with water, and other low lubricity fluids
• Great for high frequency, dithering applications
• Lightweight, compact construction
• Easily field repairable
• Safety; cannot be disassembled under pressure
