Parker Introduces Complete Line of Bladder Replacement Kits for the Wind Turbine Industry

Kits are readily available for the reconditioning of Parker and Non-Parker accumulators.


Machesney Park, Illinois, September 9, 2021 Parker Accumulator and Cooler, a division of Parker Hannifin Corporation, the global leader in motion and control technologies, has introduced a complete line of bladder replacement kits for bladder-style accumulators used in the wind turbine industry. The kits allow wind turbine technicians to replace bladders in the field, avoiding potential downtime and power capacity disruption.


The bladder replacement kits are engineered with unique rubber compounds that Parker formulated specifically for demanding wind turbine applications where long service life is critical to system performance. The proprietary compounds, which include Buna Nitrile, Hydrin, Butyl, EPR, Fluorocarbon, and Neoprene, suit various fluids and temperatures. Parker’s high-quality elastomer bladder materials withstand vibration and significantly reduce gas permeation in extreme temperatures, avoiding pre-charge losses that can lead to poor performance and premature bladder failure when left unchecked.


“With industry-leading Greer and Olaer bladder products, Parker has over 70 years of expertise in formulating proven bladder compounds and making the finest quality bladder accumulators,” said Bob Rajabi, Global Business Development Manager, Parker Accumulator and Cooler Division. “Our bladder replacement kits are designed with sustained performance in mind, delivering lower lifecycle costs on expensive systems,” Rajabi added. “Understanding the availability of spare parts is critical for wind farm owners and operators to keep their operations running smoothy, we stock thousands of specialized wind turbine supplies to meet fast lead times.”


Parker’s bladder replacement kits are available in capacities ranging from 2.5 - 15 gallon (10 to 57 liters) with several gas valve types and stem sizes. Genuine Parker spare parts are sold globally from authorized distributors and Parker Repair Centers, ensuring Parker products perform as originally designed and manufactured. The new bladder replacement kits offered by Parker Accumulator and Cooler may also be used on corresponding non-Parker manufactured accumulators. 


Additional Parker bladder replacement kit features include:

  • Dual certified to ASME and PED
  • An extended lifetime with increased fatigue resistance
  • Operating temperature ranges from -40°F to 225°F (-40°C to 107°C)
  • Reduced maintenance costs due to lower than standard gas permeation rate
