Annotation of standard text ČSN EN ISO 15783 (113015):

This document specifies the requirements for seal-less rotodynamic pumps that are driven with permanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemical processes, water treatment and petrochemical industries. Their use can be dictated by space, noise, environment or safety regulations.

Seal-less pumps are pumps where an inner rotor is completely contained in a pressure vessel holding the pumped fluid. The pressure vessel or primary containment device is sealed by static seals such as gaskets or O-rings.

Pumps normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection, electromagnetic compatibility), except where special requirements are specified herein.

This document includes design features concerned with installation, maintenance and operational safety of the pumps, and defines those items to be agreed upon between the purchaser and manufacturer/supplier.

Where conformity to this document has been requested and calls for a specific design feature, alternative designs can be offered providing that they satisfy the intent of this document and they are described in detail. Pumps which do not conform with all requirements of this document can also be offered providing that the deviations are fully identified and described.

Whenever documents include contradictory requirements, they are applied in the following sequence of priority:

• a) purchase order (or inquiry, if no order placed), see Annexes C and D;
• b) data sheet (see Annex A) or technical sheet or specification;
• c) this document;
• d) other standards
