Pump, pump, pump, pump, pump, pump, pump, yes! THAT'S what Cyclone needs....a good feed pump. Having multiple coils, each fed by a separate pumping element, is problematic. If one pumping element starts to lose flow, that coil will burn out and you might not even know since all the rest are getting fluid. I think any Rankine Cycle engine with parallel steam production is asking for problems unless you have a fairly intricately wired control system.
