It is perfect to work with large volume and temperature variations.
It is manufactured with an accurately and internally machined tube, and a piston as the element between the fluid and the gas.
It is possible to work with several special types of sealing and use 100% of the internal capacity.

There are many functions for the piston accumulator applications, the main one is to receive the fluid under pressure and at a certain volume, and supply the same volume to the installation, when needed.

With the fluid under pressure, every accumulator is considered as a pressure vessel that needs to be designed for maximum working pressure in accordance to the standard of the country where it is.

In order to have the maintenance procedure or preload reading, the system should be turned off and depressurized. It is important to have the hydrostatic test at regular intervals in order to ensure product safety conditions.
