RE: Sealless pump stds.

Design standards for sealless pumps include ANSI b73.1 and ISO2858 (European spec) which cover dimensional/construction specifications, but the sealless element (whether mag-drive or Canned) is seen as a sealing option as opposed to stand alone pump design to which a standard applies to.
