How many manifolds can one circulator service? Is it strictly one for one?

Circulator-How many manifolds?
The diagrams that I have seen show 1 circulator pumping to 1 manifold. Can 1 circulator be piped so that more than 1 manifold is used?

Whole houses being done with one pump....
There is a LOT more to sizing a pump than meets the eye. It is based on worst case pressure drop of all connected circuits, and the maximum GPM flow rate required for ALL connected loads. I have many houses with one circulator serving many manifolds. In todays economic/environmentally aware society, variable speed REALLY makes sense.
You could do the one pump per manifold thing for redundancy, but then when all the pumps are running, you will need AC in the mechanical room to keep the room reasonably cool. I'm sure the pump manufacturers would LOVE to have you use one per manifold...
With todays technology (WILO and Grundfos and a few others), variable speed circulators are the only way to go with variable loads. If the load is a fixed, constant, then stick with conventional technology, but if there are variables, then use a variable speed pump to meet your needs.
