1.1 <\/b>This International Standard specifies the requirements for seal-less rotodynamic pumps that are driven with<\/p>\n
permanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemical<\/p>\n
processes, water treatment and petrochemical industries. Their use can be dictated by space, noise, environment<\/p>\n
or safety regulations.<\/p>\n
Seal-less pumps are pumps where an inner rotor is completely contained in a pressure vessel holding the pumped<\/p>\n
fluid. The pressure vessel or primary containment device is sealed by static seals such as gaskets or O-rings.<\/p>\n
1.2 <\/b>Pumps will normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection,<\/p>\n
electromagnetic compatibility), except where special requirements are specified herein.<\/p>\n
1.3 <\/b>This International Standard includes design features concerned with installation, maintenance and<\/p>\n
operational safety of the pumps, and defines those items to be agreed upon between the purchaser and<\/p>\n
manufacturer\/supplier.<\/p>\n
1.4 <\/b>Where conformity to this International Standard has been requested and calls for a specific design feature,<\/p>\n
alternative designs may be offered providing that they satisfy the intent of this International Standard and they are<\/p>\n
described in detail. Pumps which do not conform with all requirements of this International Standard may also be<\/p>\n
offered providing that the deviations are fully identified and described.<\/p>\n
Whenever documents include contradictory requirements, they should be applied in the following sequence of<\/p>\n
priority:<\/p>\n
a) purchase order (or inquiry, if no order placed), see annexes D and E;<\/p>\n
b) data sheet (see annex A) or technical sheet or specification;<\/p>\n
c) this International Standard;<\/p>\n
d) other standards.<\/p>\n","protected":false},"excerpt":{"rendered":"
