Vectra flow curves available?

[kc350twin]

Hello, I am very interested in purchasing a Vectra but not sure which one. I would love to reduce my electrical consumption and go with the medium but not sure if it will be enough. I have a basement sump and about 12-15 ft of head.
Will flow curves be released?

Check out aqua cave. They have flow curves there.
