Rotary positive displacement pumps - Performance tests for acceptance

This European Standard describes specified types of acceptance tests for rotary positive displacement pumps for applications other than fluid power, excluding progressing cavity and peristaltic type pumps.
This European Standard applies to the testing of pumps with and without drivers.
This European Standard covers a selection of tests to establish a uniform demonstration of the pump's ability to perform satisfactorily. It does not, however, cover all tests that may be needed for particular pump types or applications, e.g. tests for hazardous liquids or single shaft multiple pump units. Furthermore, it does not cover any noise and vibration tests, priming tests nor any hydrostatic pressure tests. Some pump types with integral relief valves may require more extensive relief valve tests than described in this European Standard. For dosing and metering applications, further tests to demonstrate the dosing and metering abilities of the pumps may be necessary.
NOTE   Extrapolation of test results to non-tested pumps is not described in this European Standard. Such extrapolation could be made or mass-produced pumps with reference to pertinent quality assurance methods and standards.

Rotierende Verdrängerpumpen - Leistungsprüfung zur Abnahme

Diese Europäische Norm beschreibt bestimmte Arten von Abnahmeprüfungen für rotierende Verdrängerpumpen die nicht für fluidtechnische Anwendungen vorgesehen sind unter Ausschluss von Exzenterschneckenpumpen und Schlauchpumpen.
Diese Norm gilt für die Prüfung von Pumpen mit und ohne Antrieb.
In der vorliegenden Norm wird eine Auswahl von Prüfungen erfasst, mit der eine einheitliche Darstellung der zufrieden stellenden Leistungsfähigkeit der Pumpen möglich ist. Es werden jedoch nicht alle Prüfungen erfasst, die möglicherweise für spezielle Pumpenarten oder -anwendungen erforderlich sind, z. B. Prüfungen für gefährliche Flüssigkeiten oder für mehrere Pumpenaggregate mit einer Welle. Nicht erfasst werden außerdem Geräusch- und Schwingungsprüfungen, Ansaugprüfungen oder andere hydrostatische Druckprüfungen. Für einige Pumpenbauarten mit eingebauten Sicherheitsventilen können umfassendere Ventilprüfungen als in dieser Norm gefordert werden. Für Dosierungs- und Zumessungs-Anwendungen sind möglicherweise weitere Prüfungen erforderlich, um die Dosierungsmöglichkeiten der Pumpen zu veranschaulichen.
ANMERKUNG   Die Extrapolation von Prüfergebnissen ist in dieser Europäischen Norm nicht beschrieben. Derartige Extrapolationen können bei Großserienpumpen mit Bezug zu einschlägigen Qualitätssicherungsmaßnahmen und Normen gemacht werden.

Pompes volumétriques rotatives - Essais de performances pour la réception

La présente Norme européenne spécifie des types d’essais de réception des pompes volumétriques rotatives pour
des applications autres que les applications hydrauliques, à l’exclusion de cavitation progressive et des pompes de
type péristaltique.
La présente Norme européenne s’applique aux essais de pompes avec et sans machine d’entraînement.
La présente Norme européenne couvre un sélection d’essais destinés à établir une preuve constante de l’aptitude
des pompes à fonctionner de façon satisfaisante. Toutefois, elle ne couvre pas tous les essais susceptibles d’être
nécessaires pour des applications ou des types de pompes particuliers, par exemple les essais relatifs aux liquides
dangereux ou aux groupes motopompes à plusieurs pompes à ligne d’arbre unique. De plus, elle ne couvre ni les
essais de bruit et de vibrations, ni les essais d’amorçage, ni les essais de pression hydrostatique. Certains types
de pompes équipées de soupapes de décharge incorporées peuvent nécessiter des essais plus approfondis de
ces soupapes que ceux décrits dans la présente Norme européenne. Pour des applications de dosage, d’autres
essais peuvent être nécessaires pour prouver la capacité de dosage des pompes.
NOTE La présente Norme européenne n’aborde par l’extrapolation des résultats d’essais aux pompes n’ayant pas subi
d’essais. Une telle extrapolation pourrait être effectuée pour des pompes produites en grandes séries, par référence à des
normes et méthodes pertinentes d’assurance de la qualité.

Overview

EN 14343:2005 - "Rotary positive displacement pumps - Performance tests for acceptance" (CEN) specifies a uniform set of acceptance tests for rotary positive displacement pumps (excluding progressing‑cavity and peristaltic types) used in applications other than fluid power. The standard applies to pumps tested with or without drivers and defines test types, test levels, measurement accuracy requirements and basic test‑loop and instrumentation arrangements. It intentionally excludes noise/vibration, hydrostatic pressure and full priming tests (priming guidance is informative in Annex B).

Key topics and technical requirements

• Test types (T1–T4):

  • T1 Flow test - verify pump flow within specified tolerance.
  • T2 Power test - verify input power within tolerance.
  • T3 Inlet pressure test - confirm satisfactory operation without cavitation at specified inlet pressures (not a cavitation limit or priming test).
  • T4 Relief valve test - verify pressure accumulation and reseating/closing behavior of relief valves.

• Test levels (L1–L5):

  • L1 Works test (pass/fail, no formal record).
  • L2 Standard test (traceable records).
  • L3–L5 Order/observed/witness tests with increasing purchaser involvement and recorded data.

• Default test parameters (unless otherwise agreed):

  • Default test type: T1 (and T4 for pumps with integral valves).
  • Default level: L2.
  • Default accuracy: Grade 2.
  • Default tolerance: Class 2.

• Measurement and instrumentation:

  • Instrumentation must meet EN ISO 10012 measurement management requirements.
  • Maximum systematic measurement uncertainties (Grade 2 typical): Flow ±4.0%, Pressure ±5.0%, Torque ±3.0%, Temperature ±3.0 °C, Speed ±1.4%, Electrical power ±3.5%, Mechanical power ±5.0%.

• Test loop and liquid handling:

  • Use a suitably dimensioned test loop (example in Annex A).
  • Newtonian test liquid with known viscosity-temperature data; maintain inlet temperature within ±1.5 °C.
  • Liquid volume to pump flow ratio should exceed 150 s for settling.
  • Provide filtration and entrained‑air separation as needed.
  • Driver must hold speed within ±5 rpm for bare‑shaft pumps.

• Organization and reporting:

  • Supplier appoints a competent person responsible for tests.
  • Test programme and acceptance criteria must be agreed prior to testing; recorded results and test reports are required for L2–L5.

Applications and who uses EN 14343:2005

• Pump manufacturers - standardize factory acceptance tests and quality records.
• Test laboratories and independent test facilities - perform repeatable, traceable acceptance testing.
• Purchasers, OEMs and end‑users - specify test level (observed/witness) and acceptance criteria in procurement.
• QA and R&D engineers - verify flow, power, inlet pressure behaviour and relief‑valve function during design validation and production acceptance.

Related standards

• EN 12723:2000 (pump terminology and symbols)
• EN ISO 10012 (measurement management systems)
• EN 10204 (types of inspection documents)

EN 14343:2005 is a CEN standard for consistent, reproducible acceptance testing of rotary positive displacement pumps and supports clear communication of test scope, limits and measurement uncertainty between suppliers and purchasers.
