The document discusses pump testing standards and their impact. It provides an overview of the ANSI/HI 14.6-2011 standard for pump acceptance testing. It explains that tolerances are needed because no pump is perfectly manufactured and tests have variability. It reviews previous standards and how they compare to the new HI 14.6-2011 and ISO 9906-2012 standards, noting the new standards allow specifying a power or efficiency tolerance. It provides default acceptance grades for different applications and discusses ensuring the supplier specifies which standard a pump curve or test is based on.

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

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.

Why Do We Need Tolerances?
4
• 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.

• 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.

Previous Testing Standards
6
• 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.

• 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 8th-10th / 11th edition
12
• API 610 8th through 10th edition had
distinct tolerances.
• 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.

• 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. Making Sense of Pump Testing Standards: How understanding standards can impact the bottom line
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.

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.
