 TITLE: Energy Conservation Program: Test Procedure for Pumps  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy 
ACTION:  Correction 
SUMMARY:    In proposed rule document 2015-06945 beginning on page 17585 in the issue of 
Wednesday, 1 April 2015, make the following correction: 
On page 17637, in the first column, beginning with the third paragraph under the section heading 
"E. Issues on Which DOE Seeks Comment" and cont inuing through to the third column, on page 
17639 up to the heading entitled "VI. Approval of the Office of the Secretary", revise the existing 
text to read as follows: 
2. DOE requests comment on the proposed defini tions for "pump," "bare pump," "mechanical 
equipment," "driver, " and "control." 
3. DOE requests comment on the proposed definitions for "continuous control" and 
"noncontinuous control." 
4. DOE also requests comment and information regarding how often pumps with continuous or 
non-continuous controls are packaged and distributed in commerce, by manufacturers, with 
integrated sensors and feedback logic that would allow such pumps to automatically actuate. 
5. DOE also requests comment on the likelihood of pumps with continuous and non-continuous 
controls being distributed in commerce, but never paired with any sensor or feedback 
mechanisms that would enable energy savings. 
6. DOE requests comment on the proposed definiti on for "basic model" as applied to pumps. 
Specifically, DOE is interested in comments on DOE's proposal to allow manufacturers the option of rating pumps with trimmed impellers as a single basic model or separate basic 
models, provided the rating for each pump model is based on the maximum impeller diameter 
for that model. 
7. DOE requests comment on the proposed definition for "full impeller." 
8. DOE requests comment on the proposal to require that all pump models be rated in a full 
impeller configuration only. 
9. DOE requests comment on any other characteristics of pumps that are unique from other 
commercial and industrial equipment and may requir e modifications to the definition of "basic 
model," as proposed. 
10. DOE requests comment on the proposed applicability of the test procedure to the five pump 
equipment classes noted above, namely ESCC, ESFM, IL, RSV, and VTS pumps. 
11. DOE requests comment on the proposed definitions for end suction pump, end suction frame 
mounted pump, end suction close-coupled pump, in-line pump, radially split multi-stage G/TBT/N/USA/980/Corr.1 
 
- 2 - 
 
  vertical in-line casing diffuser pump, rotodyna mic pump, single axis flow pump, and vertical 
turbine submersible pump. 
12. DOE requests comment on whether the references  to ANSI/HI nomenclature are necessary as 
part of the equipment definitions in the regulatory text, are likely to cause confusion due to 
inconsistencies, and whether discussing the ANSI/HI nomenclature in this preamble would 
provide sufficient reference material for manufacturers when determining the appropriate equipment class for their pump models. 
13. DOE requests comment on whether it needs to clarify the flow direction to distinguish RSV 
pumps from other similar pumps when determining test procedure and standards applicability. 
14. DOE requests comment on whether any additional language is necessary in the proposed RSV 
definition to make the exclusion of immersible pumps clearer. 
15. DOE requests comment on its proposal to exclude circulators and pool pumps from the scope 
of this test procedure rulemaking. 
16. DOE requests comment on the proposed definiti ons for circulators and dedicated-purpose pool 
pumps. 
17. DOE requests comment on the extent to which ESCC, ESFM, IL, and RSV pumps require 
attachment to a rigid foundation to function as designed. Specifically, DOE is interested to 
know if any pumps commonly referred to as ESCC, ESFM, IL, or RSV do not require 
attachment to a rigid foundation. 
18. DOE requests comment on its initial determination that axial/mixed flow and PD pumps are 
implicitly excluded from this rulemaking based on the proposed definitions and scope 
parameters. In cases where commenters suggest a more explicit exclusion be used, DOE 
requests comment on the appropriate changes to the proposed definitions or criteria that would be needed to appropriately differentiat e axial/mixed flow and/or PD pumps from the 
specific rotodynamic pumps equipment classes proposed for coverage in this NOPR. 
19. DOE requests comment on the proposed definition for "clean water pump." 
20. DOE requests comment on its proposal to incorporate by reference the definition for "clear 
water" in HI 40.6-2014 to describe the testing fluid to be used when testing pumps in 
accordance with the DOE test procedure. 
21. DOE requests comment on the proposed definition for "fire pump," "selfpriming pump," 
"prime-assisted pump," and "sealless pump."  
22. Regarding the proposed definition of a self-priming pump, DOE notes that such pumps 
typically include a liquid reservoir above or in front of the impeller to allow recirculating water within the pump during the priming cycle. DOE requests comment on any other specific design 
features that enable the pump to operate without manual re-priming, and whether such 
specificity is needed in the definition for clarity. 
23. DOE requests comment on the proposed specifications and criteria to determine if a pump is 
designed to meet a specific Military Specification and if Military Specifications other than MIL-
P-17639F should be referenced. 
24. DOE requests comment on excluding the following pumps from the test procedure: fire pumps, 
self-priming pumps, prime-assist pumps, sea lless pumps, pumps designed to be used in a 
nuclear facility subject to 10 CFR part 50--Domestic Licensing of Production and Utilization 
Facilities, and pumps meeting the design and cons truction requirements set forth in Military 
Specification MIL-P-17639F, "Pumps, Centrifugal, Miscellaneous Service, Naval Shipboard Use" 
(as amended). 
25. DOE requests comment on the listed design characteristics (power, flow, head, design 
temperature, design speed, and bowl diameter) as limitations on the scope of pumps to which 
the proposed test procedure would apply. 
26. DOE requests comment on the proposed definition for "bowl diameter" as it would apply to 
VTS pumps. 
27. DOE requests comment on its proposal to test pumps sold with non-electric drivers as bare 
pumps. G/TBT/N/USA/980/Corr.1

  28. DOE requests comment on its proposal that any pump distributed in commerce with a single-
phase induction motor be tested and rated in the bare pump configuration, using the calculation method. 
29. DOE requests comment from interested party on any categories of electric motors, except 
submersible motors, that: (1) Are used with pumps considered in this rulemaking and (2) 
typically have efficiencies lower than the defaul t nominal full load moto r efficiency for NEMA 
Design A, NEMA Design B, or IEC Design N motors. 
30. DOE requests comment on the proposed load points and weighting for PEICL for bare pumps 
and pumps sold with motors and PEIVL for pumps inclusive of motors and continuous or non-continuous controls. 
31. DOE requests comments on the proposed PEICL and PEIVL metric architecture. 
32. DOE requests comment on its proposal to base the default motor horsepower for the minimally 
compliant pump on that of the pump being eval uated. That is, the motor horsepower for the 
minimally compliant pump would be based on the calculated pump shaft input power of the 
pump when evaluated at 120 percent of BEP flow  for bare pumps and the horsepower of the 
motor with which that pump is sold for pumps sold with motors and controls (with or without continuous or non-continuous controls). 
33. DOE requests comment on using HI 40.6-2014 as the basis of the DOE test procedure for 
pumps. 
34. DOE requests comment on its proposal to not incorporate by reference section 40.6.5.3, 
section A.7, and appendix B of HI 40.6-2014 as part of the DOE test procedure. 
35. DOE requests comment on its proposal to require that data be collected at least every 5 
seconds for all measured quantities. 
36. DOE requests comment on its proposal to allow dampening devices, as described in section 
40.6.3.2.2, but with the provison noted above (i.e., permitted to integrate up to the data 
collection interval, or 5 seconds). 
37. DOE requests comment on its proposal to require data collected at the pump speed measured 
during testing to be normalized to the nominal speeds of 1,800 and 3,600. 
38. DOE requests comment on its proposal to adopt the requirements in HI 40.6-2014 regarding 
the deviation of tested speed from nominal speed  and the variation of speed during the test. 
Specifically, DOE is interested if maintaining tested speed within 1 percent of the nominal 
speed is feasible and whether this approach would produce more accurate and repeatable test 
results. 
39. DOE requests comment on the proposed voltage, frequency, voltage unbalance, total harmonic 
distortion, and impedance requirements that ar e required when performing a wire-to-water 
pump test or when testing a bare pump with a calibrated motor. Specifically, DOE requests comments on whether these tolerances can be achieved in typical pump test labs, or whether 
specialized power supplies or power conditioning equipment would be required. 
40. DOE requests comment on its proposal to test RSV and VTS pumps in their 3- and 9-stage 
versions, respectively, or the next closest number of stages if the pump model is not distributed in commerce with that particular number of stages. 
41. DOE requests comment on its proposal to use a linear regression of the pump shaft input 
power with respect to flow rate at all the tested flow points greater than or equal to 60 percent of expected BEP flow to determine the pump shaf t input power at the specific load points of 
75, 100, and 110 percent of BEP flow. DOE is especially interested in any pump models for 
which such an approach would yield inaccurate measurements. 
42. DOE requests comment on its proposal that for pumps with BEP at run- out, the BEP would be 
determined at 40, 50, 60, 70, 80, 90, and 100 pe rcent of expected BEP flow instead of the 
seven data points described in section 40.6.5.5.1 of HI 40.6-2014 and that the constant load points for pumps with BEP at run-out shall be 100, 90, and 65 percent of BEP flow, instead of 
110, 100, and 75 percent of BEP flow. 
43. DOE requests comment on the type and accuracy of required measurement equipment, 
especially the equipment required for electrical power measurements for pumps sold with motors having continuous or noncontinuous controls. G/TBT/N/USA/980/Corr.1

  44. DOE requests comment on its proposal to conduct all calculations and corrections to nominal 
speed using raw measured values and that th e PERCL and PEICL or PERVL and PEIVL, as 
applicable, be reported to the nearest 0.01. 
45. DOE requests comment on its proposal to determine the default motor horsepower for rating 
bare pumps based on the pump shaft input power at 120 percent of BEP flow. DOE is 
especially interested in any pumps for which the 120 percent of BEP flow load point would not be an appropriate basis to determine the default motor horsepower (e.g., pumps for which the 
120 percent of BEP flow load point is a significantly lower horsepower than the BEP flow load 
point). 
46. DOE requests comment on its proposal that wo uld specify the default, minimally compliant 
nominal full load motor efficiency based on the applicable minimally allowed nominal full load 
motor efficiency specified in DOE's energy conservation standards for NEMA Design A, NEMA 
Design B, and IEC Design N motors at 10 CFR 431.25 for all pumps except pumps sold with submersible motors. 
47. DOE requests comment on the proposed default mi nimum full load motor efficiency values for 
submersible motors. 
48. DOE requests comment on defining the proposed  default minimum motor full load efficiency 
values for submersible motors relative to the most current minimum efficiency standards 
levels for regulated electric motors, through the use of "bands" as presented in Table III.6. 
49. DOE requests comment on the proposal to allow the use of the default minimum submersible 
motor full load efficiency values presented in Table III.6 to rate: (1) VTS bare pumps, (2) 
pumps sold with submersible motors, and (3) pumps sold with submersible motors and 
continuous or noncontinuous controls as an option instead of wire-to-water testing. 
50. DOE requests comment on the development and use of the motor part load loss factor curves 
to describe part load performance of covered motors and submersible motors including the 
default motor specified in section III.D.1 for bare pumps and calculation of PERSTD. 
51. DOE requests comment on its proposal to determine the part load losses of motors covered by 
DOE's electric motor energy conservation standa rds at 75, 100, and 110 percent of BEP flow 
based on the nominal full load efficiency of the motor, as determined in accordance with DOE's electric motor test procedure, and the same default motor part load loss curve applied to the default motor in test method A.1 for the bare pump. 
52. DOE requests comment on its proposal to determine the PERCL of pumps sold with 
submersible motors using the proposed defaul t minimum efficiency values for submersible 
motors and applying the same default motor part load loss curve to the default motor in test 
method A.1 for the bare pump. 
53. DOE also requests comment on its proposal that pumps sold with motors that are not 
addressed by DOE's electric motors test procedure (except submersible motors) would be 
rated based on a wire-to-water, testing-based approach. 
54. DOE requests comment on the proposed system curve shape to use, as well as whether the 
curve should go through the origin instead of the statically loaded offset. 
55. DOE requests comment on the proposed calculation approach for determining pump shaft 
input power for pumps sold with motors and continuous controls when rated using the 
calculation-based method. 
56. DOE requests comment on the proposal to adopt four part load loss fact or equations expressed 
as a function of the load on the motor (i.e., motor brake horsepower) to calculate the losses of 
a combined motor and continuous controls, where the four curves would correspond to different horsepower ratings of the continuous control. 
57. DOE also requests comment on the accuracy of the proposed equation compared to one that 
accounts for multiple performance variables (speed and torque). 
58. DOE requests comment on the proposed 5 percent scaling factor that was applied to the 
measured VSD efficiency data to generate the proposed coefficients of the four part load loss 
curves. Specifically, DOE seeks comment on whether another scaling factor or no scaling factor 
would be more appropriate in this context. G/TBT/N/USA/980/Corr.1

  59. DOE requests comment on the variability of control horsepower ratings that might be 
distributed in commerce with a given pump and motor horsepower. 
60. DOE requests comment and data from interested parties regarding the extent to which the 
assumed default part load loss curve woul d represent minimum efficiency motor and 
continuous control combinations. 
61. DOE requests comment on its proposal to require testing of each individual bare pump as the 
basis for a certified PEICL or PEIVL rating for one or more pump basic models. 
62. DOE requests comment on its proposal to limit the use of calculations and algorithms in the 
determination of pump performance to the calculation-based methods proposed in this NOPR. 
63. DOE requests comment on its proposal to determine BEP for pumps rated with a testing-based 
method by using the ratio of input power to the dr iver or continuous control, if any, over pump 
hydraulic output. DOE also seeks input on the degree to which this method may yield 
significantly different BEP points from the case where BEP is determined based on pump efficiency. 
64. DOE requests comment on the proposed testing-based method for pumps sold with motors 
and continuous or non-continuous controls. 
65. DOE requests comment on the proposed testing-based method for determining the input 
power to the pump for pumps sold with motors and non-continuous controls. 
66. DOE requests comment on any other type of non-continuous control that may be sold with a 
pump and for which the proposed test procedure would not apply. 
67. DOE requests comment on its proposal to establish calculation-based test methods as the 
required test method for bare pumps and testing-based methods as the required test method 
for pumps sold with motors that are not regulated by DOE's electric motor energy conservation standards, except for submersible motors, or for pumps sold with any motors and with 
noncontinuous controls. 
68. DOE also requests comment on the proposal to allow either testing-based methods or 
calculation-based methods to be used to rate pumps sold with continuous control-equipped 
motors that are either (1) regulated by DOE' s electric motor standards or (2) submersible 
motors. 
69. DOE requests comment on the level of burden to include with any certification requirements 
the reporting of the test method used by a ma nufacturer to certify a given pump basic model 
as compliant with any energy conservation standards DOE may set. 
70. DOE requests comment on the proposed sampling plan for certification of commercial and 
industrial pump models. 
71. DOE requests comment regarding the size of pump manufacturing entities and the number of 
manufacturing businesses represented by this market. 
72. DOE requests comment on its assumption that, fo r most pump models, only physical testing of 
the underlying bare pump model is required, and subsequent ratings for that bare pump sold 
with a motor or motor and continuous control can be based on calculations only. 
73. DOE requests information on the percentage of pump models for which the rating of the bare 
pump, pump sold with a motor, and pump sold with a motor and controls cannot be based on 
the same fundamental physical test of the bare pump. For example, DOE is interested in the 
number of pump models sold with motors that are not covered by DOE's energy conservation standards for electric motors or the number of pump models sold with controls that would not 
meet DOE's definition of continuous control. 
74. DOE requests comment on the testing currently conducted by pump manufacturers and the 
magnitude of incremental changes necessary to transform current test facilities to conduct the 
DOE test procedure as described in this NOPR. 
75. DOE requests comment on its assumption that using a non-calibrated test motor and VFD 
would be the most common and least costly approach for testing bare pumps in accordance with the proposed DOE test procedure. 
76. DOE requests comment on the estimates of materials and costs to build a pump testing facility 
as presented. G/TBT/N/USA/980/Corr.1

  77. DOE requests comment on the test facility description and measurement equipment assumed 
in DOE's estimate of burden. 
78. DOE requests comment and information regarding the burden associated with achieving the 
power quality requirements proposed in the NOPR. 
79. DOE requests comment on the number of pump models per manufacturer that would be 
required to use the wire-to-water test method to certify pump performance. 
80. DOE requests comment on the estimation of the portion of pumps that would need to be newly 
certified or recertified annually. 
81. DOE requests comment on the use of annual sales as the financial indicator for this analysis 
and whether another financial indicator would be  more representative to assess the burden 
upon the pump manufacturing industry. 
82. DOE requests comment on its conclusion that the proposed rule may have a significant impact 
on a substantial number of small entities. DOE is particularly interested in feedback on the assumptions and estimates made in the analysis of burden associated with implementing the 
proposed DOE test procedure. 
83. DOE requests comment on the burden estimate to comply with the proposed recordkeeping 
requirements.
