Kral KF-42.BAA.000469 Triple Screw Pump is a high-efficiency positive displacement unit, meticulously refurbished and pressure-tested to restore factory performance. Ideal for smooth and reliable fluid transfer, this pump is designed to handle clean oils, light fuels, hydraulic fluids, and lubricants with minimal pulsation—making it a dependable choice for marine, industrial and power-generation lubrication systems where consistent flow and quiet operation are critical.
At its core, the KF-42.BAA features a precision-engineered triple-screw rotor assembly. A central drive screw engages two idler screws, creating sealed, continuously moving chambers that transport fluid axially in a stable, low-shear flow. This triple-screw geometry not only ensures high volumetric efficiency and volumetric displacement consistency but also balances internal loading, reducing bearing wear and enhancing longevity under continuous operation.
Fully restored to OEM tolerances, this pump underwent a thorough refurbishment process that included re-machining or replacing key components such as screws, bearings, seals, and housing bores. The unit was then rigorously pressure-tested to confirm leak-free performance and consistent hydraulic characteristics comparable to a new pump. The BAA suffix denotes specific porting, flow capacity, and mounting configurations, ensuring straightforward integration into OEM or existing system layouts without additional modifications.
Constructed from premium, wear-resistant materials and precision-machined to tight clearances, the pump delivers reliable service in demanding environments. Its compact footprint and standardized flanges support easy retrofitting, while internal elements are accessible for efficient maintenance, minimizing downtime. Overall, the Kral KF-42.BAA.000469 Triple Screw Pump offers a cost-effective, high-performance solution—combining quiet, pulse-free operation with restored OEM accuracy, durability, and compatibility—perfect for maintaining operational integrity in critical fluid-handling systems.
