VS8 products can get up to 1,000 feet of head and most sizes above 600

(VS0), all have capability of above 500‐600 feet of head. Some 9 stage M

over 460 feet of head at 3600 rpm but would fall under at 1800 rpm.

 Definition from EU 547:

• ‘Clean water’ means water with a maximum non‐absorbent free 

of 0.25 kg/m3, and with a maximum dissolved solid content of 50 

provided that the total gas content of the water does not exceed 

saturation volume. Any additives that are needed to avoid water 

down to ‐10°C shall not be taken into account.

 Defining ‘clean water’ may not be necessary for this rulemakin

• Define excluded types (i.e., solids‐handling, API 610, etc.)

• Define specific covered types (i.e., ESCC, ESFM, etc.)

• Define specific parameters (i.e., flow, head, etc.)

•  If pump is not of an excluded type, is of a specific covered type

specified design parameters, pump is covered.

 Notes:

• Need to (1) define clean water pumps or (2) look into a more com

list of exclusions

• DOE to make proposals for next meeting to accomplish agreed up

Scope Discussion ‐ Circulator Energy Use Shipments Data

• HI: 1.7 million [1/25‐3 HP, wet and dry]

- Does not seem realistic. 78W is less than the operating electric power dr

common “1/25 HP” nameplate circulators. HI survey collected data on 1/circulators.
