Overview
EN ISO 14847:1999 - Rotary positive displacement pumps - Technical requirements specifies the technical requirements for rotary positive displacement pumps and rotary pump units. The standard defines the scope of technical characteristics and documentation requirements other than safety and testing. It applies to a range of rotary positive displacement pumps used in industrial and process applications but excludes rotary pumps used for fluid power applications. EN ISO 14847:1999 has been adopted in national bodies (for example, SIST EN ISO 14847:2002 in Slovenia).
Key topics and technical requirements
While this standard focuses on technical requirements rather than prescriptive test or safety procedures, key topics typically addressed include:
- Definition of pump types and units covered by the standard (rotary positive displacement designs).
- Design and construction considerations relevant to functional performance and interchangeability.
- Materials and corrosion resistance considerations for wetted parts to ensure durability in process environments.
- Performance characteristics and data that manufacturers should supply to enable correct selection (e.g., flow, pressure ranges, operating limits).
- Dimensional and installation interfaces to aid compatibility between pump units and plant systems.
- Marking and documentation requirements, including information to be provided with the pump unit (identification, ratings, operating limits).
- Exclusions and application limits, explicitly noting that fluid power applications are outside the standard’s scope.
Note: EN ISO 14847:1999 addresses technical specifications and does not replace specific safety standards or testing protocols.
Applications and who uses this standard
EN ISO 14847:1999 is practical for:
- Pump manufacturers developing and documenting rotary positive displacement pump designs to meet market and regulatory expectations.
- Equipment specifiers and procurement teams in process, chemical, food, pharmaceutical and utility sectors who must compare technical characteristics across vendors.
- Engineers and system integrators designing pump packages and selecting compatible pump units for industrial systems.
- Maintenance and reliability professionals who require clear technical documentation for spare parts, retrofits and lifecycle planning.
The standard helps ensure consistent technical information, aiding procurement, design integration and supplier communication.
Related standards
- EN ISO 14847:1999 is the ISO reference and has been adopted as national standards (e.g., SIST EN ISO 14847:2002).
For testing, safety, and specific performance verification, users should consult the appropriate complementary standards and industry testing protocols since EN ISO 14847:1999 excludes those aspects.
