ABSTRACT:
A leak detector for a pump having a plurality of stacked diaphragms includes a plurality of flat spacer rings each having discontinuous channels and being disposed in face-to-face abutting and stacked relationship with one another wherein the discontinuous channels of the spacer rings together form tortuous leak paths extending through the flat spacer rings from working areas of the pump to a point outside of sealing areas thereof. A port is disposed in fluid communication with the port and an apparatus is provided for developing a visual indication of fluid in the port. A circumferential fluid-tight seal is disposed radially outside of the port for sealing off fluid loss beyond the outer periphery of the plurality of diaphragms and flat spacer rings.
