At no time have did I claim that the SMC Twin Pump system (that this OP appears to have) is a divertor, but you seem to prefer to believe that I did.And no matter how you try and word it it is NOT a divertor its A PUMP pure and simple.
By all means dance around in glee at knowing something that I didn't, but you seem hell bent on believing that I said the pump was a divertor, when I clearly I said it looked like a divertor (because it had three pipe connections) in order to identify it to the OP. It was certainly a clumsy description, but given that I asked what it was, you merely have to use a tiny amount of imagination to see what I was driving at.Just consider yourself educated on this matter you may come up against in the future and you will not look stupid infront of a customer saying your divertor is bust
Returning to your point about the Grundfos pump plan, which you claim is the same as the SMC Twin Pump configuration, you are completely and utterly wrong. The only similarity is that there are two pumps.
I have no problem with not knowing something, whether in front of a customer or not, so your weak jibes are falling on stony ground.
The whole nub of problem solving is analysis, not knowledge. If you applied more of the former then you'd understand my point about the parallel and series topologies. However, I realise that you might be pretending to misunderstand. Whichever one of those is true, I can't work out which is the more pathetic.
