I have 2 Little Giant 1/2 HP mag Drive external pumps for sale. They are rated at 2150 GPH at 5 feet of head. Here is a link:

They retail for $650, selling for $200 firm each. They don't come with power cords so they will need to be installed (they come this way from the factory). PM me if interested.
Thanks
Chris
