Diaphragm accumulators are compact hydraulic accumulators designed to store pressurised fluid using an elastomer diaphragm and gas precharge. The product family consists exclusively of diaphragm accumulators, with Parker Hannifin DA series, previously designated as ELM, forming the core offering. These Parker diaphragm accumulators are specified by nominal volume, maximum working pressure and connection type, supporting standardized integration into hydraulic circuits. The design allows rapid response and stable separation of gas and fluid across operating cycles. The category is based on genuine Parker components, technical support and efficient worldwide delivery.
