Several manufacturers use a version of the Century V-Green motor for their variable speed pumps. They even have similar connections in the electrical compartment. What matters is if they enable the drive software to be compatible with the automation.
As far as I know, Century configures the drive assemblies that they supply to manufacturers to only work with that manufacturer’s automation.
In other words, even though they are almost identical motors, Century does not make the drive assemblies compatible or interchangeable. There might be a way to make them work, but you would need to check with Century.
The pumps can be controlled by relays, but that is a workaround solution.
A.O Smith and Century were acquired by Regal Beloit in 2011.
One of the challenges going forward is that as people adopt automation and equipment becomes more intelligent, the automation might not cooperate with competing brands of equipment.
