BBM Alm Hi- Performance Water Pump

The PRW Industries BBM Alm Hi-Performance Water Pump (MPN 1444001) is a mechanical high-performance water pump engineered for Mopar B/RB-series and 426 Hemi engines. Built from aluminum construction with a natural finish, this pump delivers the cooling capacity and reliability required in high-output engine builds where factory cooling systems fall short. The 5/8-inch pilot design ensures proper fitment and alignment within the engine block, a critical specification for preventing leakage and maintaining consistent coolant flow under demanding conditions.

High-performance water pumps differ from stock units in impeller design and bearing support, which directly affect flow rate and durability under sustained high RPM operation. The aluminum construction provides weight savings compared to cast iron alternatives while maintaining thermal stability. The pilot specification ensures compatibility with Mopar B/RB-series and 426 Hemi engine blocks, critical for correct installation depth and seal integrity. This pump is sold as a single unit, ready for installation in compatible engine applications.

This pump serves builders and enthusiasts restoring or modifying classic Mopar muscle cars and high-performance engine builds where original cooling systems are inadequate. It addresses the specific cooling demands of B/RB-series and 426 Hemi engines during extended driving, track use, or increased power output. Whether upgrading a restoration project or supporting an engine modification, this water pump provides the flow characteristics needed to maintain stable operating temperatures and protect critical engine components.

PRW Industries is recognized in the Mopar and classic automotive community for producing OEM-quality cooling and water management components. Selecting the correct water pump for your specific engine block and year is essential—verify your engine's exact series and generation before ordering to ensure proper fitment and performance.
