Fast Logistics Speed Engine Oil Pump Faw Semi Trailer Truck Accessories Z20190015 Oil Pump

The Engine Oil Pump Assembly (Part No. Z20190015) is an original equipment (OE) component produced by Weichai Power, designed specifically for light- to medium-duty diesel engines within the Weichai WP3 series platform. As a core element of the engine lubrication system, it functions as the "heart" of the powertrain — drawing engine oil from the sump and pressurizing it for delivery to critical components such as the crankshaft, camshaft, connecting rods, and turbocharger bearings.

Featuring either an internal gear-type or rotor-type mechanical design, this oil pump delivers consistent flow and stable pressure across a wide RPM range, ensuring reliable hydrodynamic lubrication under both cold start-up and high-temperature operating conditions. Built with precision-machined gears/rotors and durable housing materials, Z20190015 supports extended engine life, reduced internal wear, and improved reliability in commercial and passenger applications alike.
