A hydraulic pulse dampener has two diaphragms, each positioned opposite a recess formed in the housing. The regions between the diaphragms and the associated recesses are sealed from the fluid which flows through the dampener so that a rise in pressure in the fluid may cause each diaphragm to flex towards the recess behind until it may completely nest in it. The diaphragms are designed differently so that they will begin to flex and take a completely nested position in different pressure ranges.
