DNJ® Engine Oil Pumps are critical components that circulate oil under pressure throughout the engine to lubricate rotating and sliding parts. These pumps are designed to maintain consistent oil flow, helping prevent friction, wear, and overheating. Each pump includes the housing, internal rotors or gears, and a pressure relief valve to regulate oil pressure under variable operating conditions.

DNJ® Engine Oil Pumps are engineered for durability and precision, featuring robust housings made from cast aluminum or cast iron to resist warping and corrosion under extreme engine temperatures. Inside, high-strength gears or rotors are crafted from hardened steel to provide long-lasting wear resistance and maintain the tight tolerances necessary for efficient oil flow. Each unit includes a pressure relief valve with a steel spring and plunger assembly to regulate system pressure and protect the engine during cold starts or high-speed conditions. Manufactured to meet or exceed OEM quality standards, DNJ® oil pumps deliver reliable performance under demanding conditions.

DNJ® also offers a full line of related lubrication system components, including oil pump repair kits, oil seals, oil pan gaskets, complete gasket sets, timing covers, and more to support engine rebuilds. With precision engineering and top-tier materials, DNJ® Engine Oil Pumps deliver exceptional performance and long-lasting durability.
