LaBour - TFA ANSI  B73.1 Horizontal Centrifugal Pump - Triple Volute

Triple volute provides three separate flow paths within the casing for the liquid.  The advantage to the design is providing a balanced radial loading of the impeller independent of condition point on the performance curve.  The solution travels a shorter path within the pump -- this offers advantages for liquids that are viscous or sheer sensitive.    Triple volute pumps prevent vapor lock and can pump solutions that contain up to 20% entrained vapors.

Flows to 800 GPM - Pressure to 440 feet

3 x 2 x 6 (A10) through 4 x 3 x 11 (A70)
