HYDSTAR® oil pumps effectively reduce wear on engine and transmission systems and prevent mechanical damage caused by poor lubrication by maintaining an efficient, stable lubricating oil circulation. Whether for routine maintenance, major overhauls, or component replacement, HYDSTAR® oil pumps deliver reliable lubrication and oil supply solutions under demanding operating conditions.

Our oil pumps feature precision-machined, wear-resistant stainless steel drive shafts; durable gears (or impellers) designed to provide stable oil pressure and superior flow rates; and hardened bearing retaining rings that enhance bearing stability. Optimized, high-quality oil seals and gaskets help prevent internal leakage, minimize wear, and significantly extend service life.

Each HYDSTAR® oil pump is manufactured to strict quality standards and undergoes rigorous pressure and flow testing to ensure reliable performance, durability, and consistent oil delivery efficiency. Designed specifically for various types of heavy-duty equipment and high-load applications, HYDSTAR® oil pumps help extend the lifespan of core components, ensure efficient engine operation, and deliver reliable overall performance.
