HVAC Pros Ask...
Question: Can a 60 cycle 00 Series Circulator run at the lower 50 cycle?

Answer: Yes, however there will be approximately 10% degradation in output. As the cycles are reduced, so is the pump speed causing the reduction in output. Additionally, I should mention that a 50 cycle pump cannot operate at a higher cycle.
