Edwards Accumulators

Maximize Extraction Rate

Edwards Engineering has more than 50 years experience in the sugar cane industry and more than 10,000 accumulators in worldwide sugar mill use today. We have specifically designed hydro-pneumatic bladder accumulators with a field proven design to fit the requirements of your sugar cane mill systems, where a pressure transfer device with positive separation between two media is needed.

The hydro-pneumatic bladder accumulator is essentially a fluid pressure storage chamber in which the potential energy of an incompressible fluid under pressure can be stored against a compressible force of a gas (nitrogen) to do useful work. This stored fluid is readily available to perform a given task when called upon by the requirements of the system in which it is used.

The flexible rubber bladder in the enclosed shell is precharged with nitrogen, to a pressure determined by the system's working pressures and loads. When the hydraulic system pump forces fluid into the fluid chamber the gas inside the bladder compresses until the gas pressure becomes equal to the system pressure. The stored potential energy of the fluid held under pressure serves as a quick secondary source of energy.
