teel booster pumps

Have found that the two Teel Booster pumps on the spotless Rinse system Froze during the last cold snap. Are these pumps repairable, can you replace just the pump part. New ones look to be $500.00 each and I hate to throw away good motors. I hate when this kind of thing happens on a weekend and Nobody is open to talk to :)
Any experts lurking on a sunday .

Your best bet will be to try and find a used pump with the motor out and make a whole one out of the parts. It will likely cost you almost as much to repair a frozen and damaged pump head with new parts as it will to replace the whole thing with a new one.
