I see them in the D&G catalog. Don't know if anyone else is using those pumps. I guess it's a food grade nylon pump from flojet but that's about as much as I know. Seems handy not to need air. I know an air pump is seen as the best, but I only make 200-300 gallons a year and not needing another air compressor would be great. I'd love to hear whatever thoughts you night have.

Thanks!
