The old generation of Ultimax pumps were made by Ultrajet up to about 2011. Balboa Water Group is now the manufacturer of these pumps and the replacement parts, most of these pump parts now made by Balboa are backwards compatible and should fit the older standard Ultrajet generation of the Ultimax series pumps
