meets the requirements of API 610/ISO 13709

• A chemical process pump that meets the requirem

ANSI/ASME B73.1, ANSI/ASME B73.2, or ISO 2858 5199

Clean Water DefinitionClean water means water with a maximum non‐absorbfree solid content of 0.25 kilograms per cubic meter, an

a maximum dissolved solid content of 50 kilograms per meter, provided that the total gas content of the water 

not exceed the saturation volume, and disregarding any

additives necessary to prevent the water from freezing 

minimum of ‐10 C

Increases in circulator MSP could occur for two distinct 

1. Increased motor cost

• Switching from Permanent Split Capacitor (PSC) wet‐roto

will increase purchased‐parts and/or labor costs

• Motors are either manufactured in‐house, or built‐to‐spe

house. Circulator motors cannot be bought off‐the‐shelf.

• There is no publically available data on PSC wet‐rotor mo

we have not received enough data to aggregate

- In a rulemaking, we may be able to reverse engineer motor - For this exercise, we extrapolate from off‐the‐shelf motors 

rulemaking

2. Increased manufacturer markup to cover manufact

redesign and conversion costs.

Incremental Costs for Circulators
12

 CRE rule looked at off‐the‐shelf PSC and ECM motor costs for sh

ranging from 6 to 16 Watts.

 A small, 1/25 HP circulator pump requires a shaft wattage of 29

• Approximately 90 Watts of draw for a PSC and 45 Watts for an ECM

 The CRE cost curves can be extrapolated to 29.8 Watts, with the 

• PSC: $15.77• ECM: $30.87• Ratio of ECM to PSC cost: 2.0

 Recognizing that circulator PSCs are

custom‐designed, we can roughly

estimate a cost premium of 1.75x as

starting point for analysis. This results

in an estimated cost of:

• PSC (wet‐rotor): $27.60

 Assuming the 2.0 cost ratio holds:

• ECM (wet‐rotor): $55.20

 Approximate Incremental Costs of $27.60
