Most pump leaks start at a rotating shaft seal. The QBY does not have one. There are no rotating parts and no shaft passing into the fluid — the diaphragms completely separate the medium from the working parts, so there is no seal to fail and nothing to weep onto the floor.
For toxic, volatile or corrosive fluids that is a safety feature, not just a convenience: what goes in comes out, with no fugitive emissions and no contamination of the work area. It also means fewer wear parts and genuinely simple maintenance.
Applications: toxic and volatile liquids, strong acids and alkalis, corrosive media, chemical processing, pharmaceutical, electroplating
