← Back Jenbacher 1246712 Cooling Water Pump

This cooling water pump (Part Number: 1246712, often formatted as 124-6712 or superseded by the newer part number 21289066) is a critical piece of hardware designed for INNIO Jenbacher industrial gas engines. Specifically, its primary application is for the Jenbacher Type 3 engine series.

As a vital element of the engine's thermal management system, this pump is responsible for driving a stable, high-volume flow of coolant throughout the engine block and cylinder heads. This circulation ensures that the engine operates strictly within its optimal temperature parameters by effectively dissipating the massive heat generated during continuous gas combustion. A reliable and highly efficient water pump is absolutely indispensable for preventing engine overheating, protecting internal mechanical components from thermal stress and premature failure, and sustaining the overall electrical efficiency and uptime of the power plant.
