Industrial Grade Oil Accumulator is a chamber that accumulates pressurized engine oil. The Oil Accumulator holds the engine oil there until a time when oil pressure in the engine falls and feeds the oil back to the engine while the pump is rebuilding pressure. The Oil Accumulator can maintain the pressure in a system for periods when there are slight leaks without the pump being cycled on and off constantly. Industrial Grade Oil Accumulator is designed to protect system components, particularly pipe work, from potentially destructive forces.
