Foam concentrate pumps shall have means for which of the following?

Foam concentrate pumps shall have means for which of the following?

• A. Flushing.
• B. Temperature control.
• C. Automatic shutoff by timer.
• D. Visual inspection only.

Answer: (A)

The essential point is ensuring the foam concentrate pump can be purged and cleaned to keep the system ready and reliable. In foam-water systems, concentrate residues can settle, dry, or form deposits in the pump and lines. If there isn’t a means to flush, these deposits can impair pump performance, clog components, and degrade foam quality. Having a flushing capability allows the operator to purge old concentrate, clear out air and deposits, service the pump, and recharge the system with fresh concentrate, which supports proper operation when the system is actuated. The other options don’t address this maintenance and readiness need: temperature control isn’t a universal requirement for the pump in NFPA 16, automatic shutoff by timer isn’t specified as a standard, and visual inspection alone doesn’t ensure that residues are removed or the pump is ready for service.
