Back to Basics: Accumulators | Power & Motion
The Basics. A hydraulic accumulator is a pressure vessel containing a membrane or piston that confines and compresses an inert gas (typically nitrogen). Hydraulic fluid is held on other side of the membrane. An accumulator in a hydraulic device stores hydraulic energy much like a car battery stores electrical energy.
How to Ensure the Safe Operation of a Hydraulic Accumulator
The gas pre-charge for an accumulator in a storage application is typically 90% of minimum required working pressure. In this case, this equates to 218 bar or 3158 psi. Note that this is a higher pressure than many gas cylinders contain. But not all accumulators are equal of course, and so the potential danger depends on the volume …

Hydraulic Accumulators: What Are They and Why Do We Need …
Hydraulic Accumulator Maintenance Accumulators are basic devices with minimal moving parts, depending on the style of accumulator you have. Maintaining your accumulator can be dangerous and may require special third-party inspection—they are pressure vessels, just like compressed gas cylinders.
Certifications for Global Requirements
1. Canada: Canadian Registration Numbers (CRN) can be obtained by constructing an accumulator from ASME-certified material using ASME standards of design then applying for the registration number. Each province has its own registration number, thus the end destination of the accumulator must be known.
