USCG Exam PracticePumps, valves, and piping systems
Under 46 CFR §56.01-10, pump characteristic curves must be submitted for pumps in which systems, and what information may substitute for those curves?
- A. Bilge and ballast systems; substitution is not permitted under any circumstance
- ✓ Firemain and foam systems; rated capacity and head at rated capacity, shutoff head, and head at 150 percent rated capacityCorrect
- C. Firemain and foam systems; only the pump model number and manufacturer's catalog sheet
- D. All Class I piping systems; rated capacity and shutoff head only
Why B is correct
46 CFR §56.01-10(d)(2) requires pump characteristic curves for all pumps in the firemain and foam systems. Those curves need not be submitted if rated capacity and head at rated capacity, shutoff head, and head at 150 percent rated capacity are shown on the drawing.
