This presentation will give you all the details you need to know about Centrifugal Pumps Testing Standards. It talks about API 610 , HI1.6, ISO 9906. What standards to follow while specifying pump testing and tolerances.

2. Agenda
• Overview of new testing standards used in the market today
• Testing tolerances: Why they’re needed and how they work
• Understanding how tolerances impact the product received and plant
operating performance
• Which performance standards to specify, and how

3. Overview:ANSI/HI 14.6-2011
• The ANSI/HI Standard 14.6-2011
is intended to be used for
centrifugal pump acceptance
testing at recognized pump test
facilities (i.e., a manufacturer’s
facility or test laboratory).
• HI 14.6-2011 is available for
download at www.pumps.org.

4. Why Do We Need Tolerances?
• There is no such thing as a perfect cast or machined part. Everything is
subject to some variation.
• The combination of variations in the pump impeller, pump casing and
overall assembly yield a scatter in performance.
• The test loop components and
instrumentation introduce further
variability and scatter.
• The scatter can be reduced by
better manufacturing techniques
(i.e., investment cast impellers
instead of sand cast ones).
• Better manufacturing and test
techniques typically cost more.

5. Hydraulic Institute, API And ISO Pump
Performance Standards
• HI 14.6-2011 “American National Standard for Rotodynamic Pumps
for Hydraulic Performance Acceptance Tests”* (supersedes HI 1.6
and 2.6)
• API 610 11th edition
• ISO 9906-2012 “Rotodynamic pumps – Hydraulic performance
acceptance tests”*
• The direction is toward one worldwide standard for pump acceptance
testing.
*In practice HI 14.6-2011 ~ ISO 9906-2012 with common acceptance criteria

6. Previous Testing Standards
• HI Standard 1.6-2000 (for centrifugal pumps) had two acceptance levels:
Level A: (default level) At a rated head or rated flow (not both), it allowed for a
positive tolerance for head, flow and efficiency, but no negative tolerance.
Level B: At a rated head or rated flow (not both), it allowed for a positive and
negative tolerance for head, flow and efficiency.
• HI Standard 2.6 (for vertical pumps) had an acceptance standard the same
sas Level A.
• ISO 9906-1999 had two acceptance levels:
Grade 1 and Grade 2
Both had bilateral tolerances for rated head or rated flow and allowed a
negative tolerance on efficiency.
• All the above standards are withdrawn and considered obsolete.

7. Other Pump Testing Standards You May Encounter
• ASME PTC 8.2: Mainly used on
testing of larger pumps for power
station application
• DIN 1944: Obsolete and replaced
by ISO 9906
• ISO 2548: Withdrawn and replaced
by ISO 9906
• ISO 3555: Withdrawn and replaced
by ISO 9906

• The power and efficiency tolerances are not the result of an exact calculation using
the maximum values of a related column. They are instead reflecting real life
experience. For grade 1E and 1U, no negative tolerance on efficiency is allowed.
• Note: All tolerances are percentages of values guaranteed.
• Unless agreed upon with the buyer, any other specified duty points are subject
to acceptance grade 3B.

• API 610 11th edition is functionally
equivalent to HI 14.6-2011and ISO
9906-2012 Grade 1B, with an added
test point for shutoff head.
• API 610 does not have a rated flow
tolerance, making it unsuitable for
testing high specific speed pumps.
• API 610 does not have any guarantee
of efficiency (only power), making it
unsuitable for efficiency-critical
applications.

Note: This table applies where a guarantee point has been agreed
upon, but no tolerance standard has been specified.
• Both HI 14.6 and ISO 9906 set a
default test tolerance when it is not
defined by the purchaser.
• The default tolerance may not be
sufficient for your process.
• It is important that you actively review
what tolerance you require.

15. Make Sure You Understand What Is Being
Quoted To You By Your Supplier
• If you have not specified any performance criteria, what
is the supplier standard ?
• This should be identified either in the supplier proposal
or on the performance curve submitted with the bid.
• This is a critical question to ask, whether you are
purchasing a performance test or not.
• Note: It is common practice in the pump industry that all
pumps are not performance tested as standard. Many
pump manufacturers can rely on historical test data to
assure pump performance quality.
• However, all industrial pumps are pressure tested as
standard to ensure safety and structural integrity.

23. Key Takeaways
• New pump performance standards
from both HI and ISO have been
aligned to make it easier to specify
reliable and predictable pump
performance on a global basis.
• It’s important to understand what
performance will be provided if no
pump performance is specified–default standards can apply.
• Most performance standards allow for bi-lateral tolerance, which can impact life
cycle costs, as well as system performance.
