Cummins 3098964 Water Pump Assembly

The Cummins 3098964 water pump assembly is a critical component of the closed-loop cooling system for the K19 series 19-liter inline six-cylinder diesel engines. It circulates coolant through the engine block cylinder head and heat exchanger to maintain optimal operating temperatures under continuous duty cycles. The unit features a cast iron volute housing stainless steel shaft and high efficiency impeller designed for high flow rates at rated engine speeds. The assembly includes the mounting flange gasket surface and pulley hub interface compatible with standard KTA19 accessory drives. This part serves as the fresh water coolant pump distinct from raw water seawater pumps used in marine heat exchanger configurations. It is engineered to meet OEM specifications for thermal capacity and seal life in heavy duty industrial power generation construction and marine propulsion applications. Regular inspection of weep hole leakage and bearing noise is recommended per Cummins maintenance intervals.
