Possibly, if there is indeed a pressure restraint on that 300 line. Assuming there is isn't you could just let them both rip on it at the service setpoint. The small pump will probably go up to 60 Hz (flat out) and the larger will start lower then ramp up as needed.
But you couldn't do that on the upper line because the pump curve is probably way different and with lower TDH the small pump would provide additional volume but not at the working pressure to reach the higher elevations. The big pump would not be able to boost that much volume since it is a wet pet itself. The result would be worse than the 400 pump alone running.
It looked like they were making snow late last night and now it's 18 degrees and they appear to be shutdown. Wonder if something blew up. I think they were trying to add depth to Hocus and Talisman for the weekend?
