What is the difference between UL/FM certified fire pumps and standard pumps?

UL/FM fire pumps are tested and certified by internationally recognized laboratories, ensuring reliable performance under fire conditions. Standard pumps do not undergo such rigorous testing and may fail to deliver required flow and pressure during emergencies.

Yes. All fire pumps supplied by Imen Harigh Paydar are designed, assembled, and tested in full compliance with NFPA 20 requirements.
