<p><strong>1.1 </strong>This International Standard specifies the requirements for seal-less rotodynamic pumps that are driven with</p>
<p>permanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemical</p>
<p>processes, water treatment and petrochemical industries. Their use can be dictated by space, noise, environment</p>
<p>or safety regulations.</p>
<p>Seal-less pumps are pumps where an inner rotor is completely contained in a pressure vessel holding the pumped</p>
<p>fluid. The pressure vessel or primary containment device is sealed by static seals such as gaskets or O-rings.</p>
<p><strong>1.2 </strong>Pumps will normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection,</p>
<p>electromagnetic compatibility), except where special requirements are specified herein.</p>
<p><strong>1.3 </strong>This International Standard includes design features concerned with installation, maintenance and</p>
<p>operational safety of the pumps, and defines those items to be agreed upon between the purchaser and</p>
<p>manufacturer/supplier.</p>
<p><strong>1.4 </strong>Where conformity to this International Standard has been requested and calls for a specific design feature,</p>
<p>alternative designs may be offered providing that they satisfy the intent of this International Standard and they are</p>
<p>described in detail. Pumps which do not conform with all requirements of this International Standard may also be</p>
<p>offered providing that the deviations are fully identified and described.</p>
