I am confused and frustrated. We have an industrial product that includes a small water recirculation tank which includes a motor/pump assembly that is powered by 230V/360V/460Vac 3-phase. Our NRTL inspectors says this pump assembly must have UL, CSA, or equivalent. Here is a website that shows the type of assembly we are looking for:
https://www.graymills.com/fm-series.html The trouble is, Graymills, Granger, Dayton, etc. doesn't provide NRTL markings on the pumps that meet our functional requirements. They all say that most of their customers do not require these marks so they only offer a few models that do. How can this be? Am I missing something? Some say that manufacturers can get the pumps approved as part of a certification of the entire machine, but how can the pump be evaluated by a system integrator who doesn't manufacture the pump, nor has any constructional information? Wouldn't it HAVE to be done by the motor manufacturer? I keep asking our NRTL Field Inspector if he would accept such a product and the answer is no. Our CSA inspector also says no; it must have CSA or equivalent on the motor and/or motor/pump assembly. Any suggestions?
