Circulator on Supply and Return

What would be the result of using a circulator on both the supply and return? Has anyone ever done this? While this may sound like a foolish idea I believe some people thought that Homer Thrush was foolish with his first circulator.

    umm why?

    What would be the purpose? If you size the circ properly this would be redundant.

    I'm guessing

    Bruce means having some circs on the supply for their zone , and some on the return for other zones . We run into this whenever we add an indirect or an extra zone on an existing boiler .

    Pumps

    Putting two pumps (identical) on the boiler, one on the return and another on the supply (or in series), will increase the pump head capabilities, but not change the flow. I have seen this done as a way of increasing head when a single pump has been incorrectly sized.

    Putting two identical pumps in parallel on either the supply or return will increase the gpm flow to the system but not affect the head. As stated above, both concepts are redundant and are not standard practices. Just a way of fixing a bad situation or an improperly sized pump.
