Cummins K38 Oil Pump
The Cummins K38 Engine Oil Pump (Part No.: 3649677 / 3050934) is a "heart" component for the K38 and KTA38 series high-power diesel engines. As the power source of the forced lubrication system, it is responsible for drawing oil from the oil pan and pressurizing it to deliver to key friction pairs such as the crankshaft, connecting rods, and camshaft.
The K38 oil pumps provided by Wankang Electromechanical feature high-quality cast iron pump bodies and precision gear sets, specifically designed for heavy-duty applications such as mining machinery, large generator sets, and marine power that operate 24/7, ensuring stable oil pressure and sufficient flow even during high-speed operation.

Core Features and Advantages
High-Precision Gear Meshing
The precision-machined gear set ensures sufficient oil pressure at low speeds while maintaining stable flow at high speeds, reducing internal leakage and improving pumping efficiency.
Robust Pump Body Structure
The pump body is cast from high-strength gray cast iron, offering excellent vibration resistance and pressure tolerance. It effectively prevents deformation or cracking under high-load conditions, ensuring long-term reliability.
Optimized Inlet and Outlet Design
The oil inlet and outlet ports are optimized via fluid dynamics to reduce flow resistance, prevent air lock, and ensure smooth lubrication system supply, effectively reducing engine wear.
Rigorous Quality Inspection
Every oil pump undergoes strict flow and pressure testing before leaving the factory to ensure all performance indicators fully meet Cummins original technical specifications, strictly preventing defective products from entering the market.
