  • Product Detail

Bladder accumulators are a very versatile and cost effective option for numerous types of hydraulic systems involving energy storage, shock absorption, pulsation dampening, leakage loss compensation and volume compensation. They are a first choice for a great variety of general applications and have the widest range of standard sizes and model options. Bladder accumulators also have very quick shock response characteristics in sizes much larger than diaphragm accumulators.

Construction

ZP bladder accumulators consist of a welded or forged pressure vessel (shell), a bladder and ports for gas and fluid inlet. The gas and fluid sides are separated by the bladder.

Corrosion Protection

For use with certain aggressive or corrosive fluids, or in a corrosive environment, ZP offers protective coatings and corrosive resistant materials (i.e. stainless steel) for the accumulator parts that come in contact with the fluid, or are exposed to the hostile environment.

Mounting Position

ZP bladder accumulators can be installed in any orientation depending upon the application. When installing vertically or at an angle, the fluid port must be at the bottom. On certain applications listed below, specific positions are preferable:

  • Energy Storage:

vertical

  • Pulsation Dampening:

any position from vertical to horizontal

  • Maintaining Constant Pressure:

any position from vertical to horizontal

  • Volume Compensation:

any position from vertical to horizontal

Caution: Mounting a ZP bladder accumulator horizontally or at an angle will decrease the amount of usable volume available.

System Mounting

ZP bladder accumulators are designed to be screwed directly onto the system. We also recommend the use of our mounting components, to minimize risk of failure due to system vibrations.

Application

Some common applications of bladder accumulators are:

  • Agricultural Machinery & Equipment
  • Forestry Equipment
  • Oil Field & Offshore
  • Machine Tools
  • Mining Machinery & Equipment
  • Mobile & Construction Equipment
  • Off-Road Equipment
