Albin Group Premium Impeller Kit 57 x 16 x 48.2mm - 12 Blade - Spline Insert

The Albin Group Premium Impeller Kit 57 x 16 x 48.2mm - 12 Blade - Spline Insert is a direct-replacement marine cooling system component engineered for reliable centrifugal pump operation in saltwater and freshwater environments. This precision impeller serves as the rotating element responsible for circulating coolant through marine engine blocks, and is an essential wear item for boat owners and technicians maintaining Johnson Pump, Volvo Penta, Jabsco, and JMP cooling systems. When impeller blades erode or become damaged—a common result of salt corrosion and cavitation—performance degradation, overheating, and potential engine damage follow quickly.

Constructed with 12 precisely molded blades and a durable spline insert hub, this Albin Group impeller maintains optimal flow rates and pump efficiency across a wide operating range. The 57mm diameter and 16mm blade width geometry are designed to move fluid volume proportional to engine cooling demand while minimizing cavitation noise and vibration. The spline insert mounting system ensures secure engagement without slippage, eliminating wobble that could lead to premature bearing wear or seal failure. At just 0.4 lbs, the lightweight construction reduces rotational inertia and supports consistent startup and shutdown cycles typical of recreational and commercial marine use.

This kit is ideal for boat owners performing routine maintenance or emergency cooling-system repairs on vessels equipped with Jabsco 13554-0001, Johnson Pump 09-812B-1 (09-812BT-1), Volvo Penta 3588914, or equivalent systems. Technicians and DIY mechanics benefit from Albin Group's OEM-quality standards and compatibility verification across multiple original equipment manufacturers. Installation requires basic mechanical knowledge and standard marine service tools; most replacements are completed in under an hour once the pump housing is accessed. Keeping a replacement kit on hand prevents extended downtime and protects engine integrity during high-temperature operation in demanding marine environments.
