Primarily, hydraulic accumulators are available in the bladder, diaphragm, piston and membrane models. Each model is able to complete a dedicated task within the hydraulic system. Based on the application, they can be used to:
Once pre-charged, hydraulic accumulators are designated as pressure vessels and should be treated accordingly. Accumulators should be inspected at regular intervals by qualified inspectors. Service kits are also readily available.
Bladders are hydro-pneumatic accumulators with a flexible bladder. It serves as a separate element between a compressible gas cushion and the operating fluid.
Diaphragm are hydro-pneumatic accumulators with a flexible diaphragm which is used as a separation element between the compressible gas cushion and the operating fluid.
Pistons can be used as separating elements and can handle much higher gas compression ratios and flow rates.
