A diaphragm seal with a unique profile at its outer diameter and a high-pressure seal used to at least partially envelope the outer diameter of the diaphragm seal is described. The high-pressure seal may envelope an outer diameter side of the diaphragm seal such that the high-pressure seal creates a barrier between the diaphragm seal and the interface between an upper pump housing portion and a lower pump housing portion in which the diaphragm seal can be installed. The high-pressure seal may provide a 'gripping' force on the diaphragm seal so as to inhibit or prevent extrusion of the diaphragm seal in either a radially inner or radially outer direction when installed in a pump housing.
