Replacement front volute for the Ultima hot tub pump wet end. This front volute is a centre discharge with 1-1/2" intake and discharge threads (Measure 2-3/8" outside across) and only fits the 4 bolt Ultima wet end. This part is not compatible with Ultrajet whirlpool pumps.
Also replaces the Ultrajet part number PPULXVF.
The old generation of Ultima 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 Ultima series pumps
