For the start or test fire pump, there are some article requiring the thermographic measurement for the record or compare with specification
What equipment specifially are you refering to? Diesel Engine? Electric motor? Pump Controller?
As far as I know, neither NFPA 20 nor NFPA 25 has requirements of thermograhic inspections. The closest requirements are inspecting pump room temperature is above freezing and the diesel engine's water heater is operating.
Good Morning, Sorry, is for electrical motor, and tank you, I will try the home be implemeted for reasons of prevention. Because it is possible that the impeller wil rust by effect of the water?
As said before, thermographic inspections are not mandated. But it is a good preventive maintenance. You should consult each equipment manufacturer regarding operating temperatures. I do know some controller manufacturers that have their equipment be able to operate in ambient temperatures up to 60 °C and their components rated at 150 °C.
Also, impellers are usually made of a bronze alloy, so it is very unlikely it rusts. If the fire pump is being used with salt water, which requires a purpose built pump for those conditions, you should contact the manufacturer and ask them maintenance recommendations.
Thank Emmanuel, Really appreciate your answers. The impeller is only as ference to housing-Carcasa. It includes the water if is not in motion because there is not set start frequency plan. all question is for preventive maintenance. Es mas facil si se documenta un arranque de inicio de operacion para futuro comprobar el estado de la bomba de incendio, ya que el codigo es obligatorio.
