Profile: AllPro Fire Extinguisher Inspection & Service Co. specializes in providing fire extinguisher inspection services. Our fire pumps can either be powered by diesel generators or electric. Although both types of fire pumps are effective, diesel engines are capable to operate the fire pumps without electricity, which is a plus point in case of electric fires. Some electric engines are equipped with both electric and diesel generators, which enables them to switch to diesel generators when the power switches off. For diesel fire pumps checking the fuel levels is important.
