5 Stage Pump Belt Drive For Bert Drilled Shaft

The Barnes 5 Stage Pump Belt Drive For Bert Drilled Shaft is designed for high-performance engine builds, particularly in drag racing applications. This pump assembly is engineered for Bert transmission-mounted setups, allowing for efficient fuel delivery in competitive environments.

Featuring a five-stage internal rotor configuration, this pump increases displacement per revolution compared to single-stage designs, resulting in higher flow rates at lower RPMs. The drilled shaft design allows the pump to draw energy directly from the transmission case, eliminating the need for independent belt runs from the crankshaft.

Engine builders and fabricators working on vintage drag cars or new competition platforms will find this design beneficial, as it simplifies fuel system management and reduces concerns about belt tension and crankshaft load.
