Diaphragm Accumulators

Pre-charged diaphragm accumulator fixture sets are installed between the hydraulic pump and fixture or pallet to maintain pressure in hydraulic systems when the fixture is separated from the hydraulic source. Diaphragm accumulators store excess hydraulic fluid to help maintain pressure, reduce shock, and compensate for pressure fluctuations and leaks. The sets include a pre-charged accumulator, shut-off valve, gauge, and coupler.

Uncharged diaphragm accumulators are used in low flow-rate hydraulic systems to store pressurized hydraulic fluid and release it as needed in order to maintain steady pump flow and pressure, dampen vibration and shock, and compensate for leaks or thermal expansion in the system. They need to be charged with nitrogen before they can be used. They can also be used as a source of power in an emergency. They are completely sealed and can be mounted in any position.
