Send a part number or nameplate photo. We respond within one business day.
Request a QuoteA hydraulic accumulator stores energy and absorbs shock, and it does both through a gas charge separated from the oil by a bladder, diaphragm or piston. When the separating element fails or the pre-charge leaks away, the system loses its shock absorption and pressure spikes start propagating into the rest of the circuit.
Pre-charge pressure is not a fit-and-forget setting. It should be checked on a schedule, because a slowly falling charge changes the accumulator's behavior long before it stops working.
Send the HYDAC part number, or the volume, pre-charge and maximum working pressure, and we will quote the accumulator or the repair kit.
Applications
- Press and machine hydraulics
- Shock and pulsation damping
- Emergency and reserve energy storage
- Pre-charge service and bladder replacement
HYDAC Hydraulic Accumulators: Common Questions
Both. Send the part number, or the volume, pre-charge and maximum working pressure, and we will quote the bladder and seal kit or the complete accumulator.
On a schedule rather than on symptoms. A falling gas charge changes the accumulator's behavior gradually, so by the time pressure spikes are reaching the rest of the circuit it has been underperforming for a while.
It follows the duty. All three separate a gas charge from the oil; they differ in volume, cycle rate and how much flow they can accept. Tell us the volume, working pressure and what the accumulator is for.
The part number if you have it. Otherwise the nominal volume, pre-charge pressure, maximum working pressure and the port size.
