Save money using an Accumulator by:

Eliminating the need for large hydraulic pumps and electric motors. An accumulator in the system ensures the correct volume of oil at the correct working pressure, even in emergency situations and compensates for variations in leakage and temperature, dampens pressure and flow pulsations, maintains system pressure when the hydraulic pump is switched off and provides hydraulic suspension.

As the oldest manufacturer of hydraulic accumulators, OLAER provides a full range of bladder accumulators, membrane accumulators and piston accumulators. They can be used in a wide range of applications such as energy storage, pulsation dampening or surge alleviation. The OLAER group has a very strong presence in highly requiring industries, such as Aerospace, Nuclear or Armament.

Accumulator Charging & Test Kits

The universal charging kit 105CK allows the charging of a wide variety of accumulators. Adaptors supplied in the kit suit US or European style gas valves as well as the OFC standard ranges, (For Hydac use the UK-Euro Kit)

The charging kit includes a bull nose adaptor for connecting directly to high pressure nitrogen cylinders. However, please note that OLAER recommend the use of a nitrogen regulator (readily available from your gas supplier) to prevent damage to the bladder during charging

The permanently mounted gauging/charging head allows precharge pressure monitoring (when the accumulator is isolated from system pressure & bled). The Universal Charge Kit is still required for initial pre-charging as well as pre-charge maintenance

Charge kit 105CK-10

  • Attache Case
  • Charging head with Gauge fitted to charging head with required pressure scale (250 bar Standard)
  • Hose assembly - 2m
  • 0.302 x 32 TPI Charging Adaptor
  • 5/8" UNF Charging Adaptor (European style) gas valve
  • Gas valve extractor
  • High pressure 690 bar gas valve core x3
  • Gas valve assembly as found on AC & NG accumulator series
  • Cylinder adaptor type 50 for N2 bottle
  • Cylinder adaptor type 51 for N2 bottle
