Problems with ammonia water pump installation
Thread Content
Our factory plans to add another ammonia pump near the ammonia tank. Seamless carbon steel pipes will be used for the installation pipelines. When installing the pump, the motor must be properly grounded; is it also necessary to ground the pump foundation? Are there any requirements regarding the grounding resistance?
Aren’t the pump foundation and the motor foundation in the same place? One foundation is grounded and the other one is also grounded; however, the motor itself requires an additional grounding connection, which can be connected to the grounding of the foundation.
The pump and the foundation are grounded separately, with specified resistance requirements.
