The new Power Pole ONE Pump has been released in both 8' and 10' BLADES at this time. I don't see any reason why it cannot be used as a replacement. Price will be a factor and considering all ONE Pumps will be going out the door married to dual BLADES I am sure it will be some time before the pump alone is available. There are some benefits to still running dual pumps.
