### Appliance Standards and Rulemaki ng Federal Advisory Committee Commercial and Industrial Pumps Working Group Term Sheet June 18, 2014

Background On July 23, 2013, DOE issued a Notice of Intent To Establish the Commercial/Industrial Pumps Working Group To Negotiate a Notice of Proposed Rulemaking (NOPR) for Energy Conservation Standards for Co mmercial/Industrial Pumps. 78 FR 44036. This working group is established under the Appliance Standards a nd Rulemaking Federal Advisory Committee (ASRAC) in accordance with the Federal Advisory Committee Act (FACA) and the Negotiated Rulemaking Act (NRA). The purpose of the worki ng group was to discuss a nd, if possible, reach consensus on a proposed rule for the energy e fficiency of commercial/industrial pumps, as authorized by the Energy Policy and Conser vation Act (EPCA) of 1975, as amended. The working group was to consist of representatives of parties having a defined stake in the outcome of the proposed standards, and w ill consult as appropriate with a range of experts on technical issues.
DOE received 19 nominations for membership. Ultimately, the working group consisted of 16 members, including one member from ASRAC and one DOE repr esentative (see Appendix A). The working group met in-person during 7 sets of meetings held December 18-19, 2013 and January 30 – 31, March 4 – 5, March 26 – 27, April 29 – 30, May 28 – 29, and June 17– 19, 2014. The working group successfully reached consensus on proposed energy conservation standards for a specific set of pumps. This document includes the working group’s recommendations to ASRAC on determining sc ope of this rulemaking as well as energy conservation standards. The group also chose to provide test procedure and metric-related recommendations to the committee.



### Definition of Covered Product Recommendation #1 . The covered product, a ‘pump,’ will be defined as below subject to potential edits necessary to accomplish the same intent:

 ‘ Pump ’ is a device that moves liquids (which may include entrained gases, free solids, and totally dissolved solids) by physical or mechanical action and includes a bare pump and, if included by the manufacturer, the mech anical equipment, driver, and controls.

Vote results : Consensus 1 (15 yes -1 no) on 3/4/2014

Recommendation #2

. The components of a ‘pump’ will be defined as below:

 ‘ Bare pump ’ is a ‘pump’ excluding mechanical equipment, driver, and controls.

 ‘ Mechanical equipment ’ is any component that transfer s energy from the driver to the bare pump.

1 There are 16 members of the working group. Consensus has been defined as no more than 2 no votes. ‘ Driver ’ is the machine providing mechanical input to drive the bare pump directly or through the mechanical equipment, and ma y include an electric motor, internal combustion engine, or gas/steam turbine.

 ‘ Controls ’ means any device that can be used to control the driver.

Vote results : Consensus (15 yes - 1 absent) on 3/4/2014

Recommendation #3

. In this rulemaking, the metric will not cover non-electric drivers. The test procedure will specify that the bare pump rating calculations for the energy conservation standard also apply to pump s with non-electric drivers.

Vote results: Unanimous on 3/26/14

### Scope Refinements Recommendation #7

. [For the in-scope pump types,] this rulemaking will be limited to pumps with the following characteristics:

 Full impeller diameter

 1-200 Horsepower (shaft power at BEP)

o applies to number of stages re quired for testi ng the standard

 25 gallons/minute and greater (at BEP)

 459 feet of head maximum (at BEP)

 Design temperature range from -10 to 120 degrees C

 Pumps designed for nominal 3600 or 1800 rpm driver speeds

 6 inch or smaller bowl diameter (VT-S/HI VSO)

Vote results: Consensus (15 yes - 1 absent) on 3/4/14

Recommendation #8

. [It has been the intent of the work ing group to limit the scope of this rulemaking to pumps designed for use in pumping clean water .] The rulemaking will explicitly exclude the following types of pu mps [that might otherwise meet the definition of an in-scope pump type]: 2

 Wastewater, sump, slurry, solids handling

o but not gray water

 API 610 pumps

 ASME/ISO chemical pumps

 Fire pumps

o if compliant with NFPA 20 a nd UL listed or FM approved

 Self-priming pumps

 Prime-assisted pumps

Vote results : Unanimous on 1/31/14

 Nuclear pumps

o Complies with ASME Boiler and Pressure Vessel Code Section III or 10 CFR 50; Non Code or Code/Safety Related.

 Navy pumps

o MIL Specification Compliant (MIL -P-17639, MIL-P-17881, MIL-P-17840, MILP-18682, MIL-P-18472)

Vote results : Consensus (14 yes - 2 absent) on 3/4/14

 Sanitary pumps

2 Definitions designed to maintain the intent of these exclusions will be proposed in the NOPR by DOE. Information in sub

‐ bullets may be used to inform these definitions.o “Hygienic” or “sanitary” pumps are t ypically used in food processing and pharmaceutical applications. They are desi gned with special parameters, specific materials and surface finish to a variety of national and international rules and regulations that will minimize the biologi cal growth inside the pump to protect public health. These design parameters and materials may result in lower efficiencies than for standard water pumps. Certifications for hygienic or sanitary products include, but are not limited to:

 3-A Sanitary Standards

 EHEDG (European Hygienic Equipm ent Design Group) recommendations

 QHD (Qualified Hygienic Design)

Vote results : Unanimous on 3/26/14



### Energy Conservation Standards Recommendation #9

. For ESCC, ESFM, IL, and VT-S pumps in both 1800 and 3600 rpm speeds, the energy conservation stan dards will be set at PER 25 (with C-values iterated to cut off exactly 25% of the pumps [in the DOE analytical team’s database]) with a compliance date 4 years from the publication of the Final Rule. For RS-V pumps, energy conservation standards will be set to harmonize with the European Unio n Lot 11 MEI 40 level, [with the intent that no models known to pass the EU standa rd would fail the US standard.]

Vote results : Consensus (14 yes – 1 abst ain – 1 absent) on 6/17/14



### Test Procedure and Metric Recommendation #10

. Pump test procedure should be in accordance with HI 40.6 for determining bare pump performance.

Vote results : Consensus (13 yes – 2 abst ain – 1 absent) on 6/18/14

Recommendation #11

. [The metric for assessing compliance with the standard would be PEI, which is constructed based on values of PER.]
Pump Energy Index (PEI) CL and VL: PER CL and VL , for a given pump model, over the PER CL for a minimally compliant pump (PER STD ) serving the same hydraulic load:

ܫܧܲ ஼௅ ൤ ൌ ܴܧܲ ௅஼ ܴܧܲ ஽்ௌ ൨

ܫܧܲ ௏௅ ൤ ൌ ܴܧܲ ௅௏ ܴܧܲ ஽்ௌ ൨Pump Energy Rating (PER) CL and VL : equally weighted average electric input power to the ‘pump’ measured (or calculated) at the driver in put or, when present, controls input, over a specified load profile:

ܲܧܴ ௅஼ ൌ෍߱ ௜ ൫ܲ ௜௡ ௜ ൯

௜

ܲܧܴ ௅௏ ൌ෍߱ ௜ ൫ܲ ௜௡ ௜ ൯

௜
Where:

 w i = weight at each load point i

 P in i = power input to the “pump” at the driver, inclusive of the contro ls if present, (hp)

 i = Percentage of flow at the best efficiency point (BEP) of the pump

 i = 110%, 100%, 75% of Best Efficiency Point (BEP) flow at nominal speed for uncontrolled pumps

 i = 25%, 50%, 75%, and 100% of BEP flow at nominal speed for pumps sold with motors and controls

Vote results : Consensus (14 yes – 1 abst ain – 1 absent) on 6/18/14



### Labeling Requirements Recommendation #12. Pumps are labeled based on the config uration in which they are sold. The following information would be required to be included on a pump nameplate:
