Schrieber Corporation of Alabama makes screw pumps. See

Don't know for sure about the medium bubble diffusers. EDI of Columbia, MO makes an excellent fine bubble diffuser. Might try Enviroquip too.

ABS Pumps now have the Nopol range of diffuser assemblies. They are common on major plants in Australia. Sharing knowledge is a way to immortality
