Hitachi Automotive Systems Americas, Inc. oil pumps are vital to protecting engine components from frictional wear and overheating. Hitachi oil pumps ensure sufficient lubrication and smooth oil circulation. Oil lubricates moving engine parts to allow them to operate smoothly with less resistance and friction. A well lubricated engine increases the odds of a longer service life from its parts. The oil pump also helps disperse engine heat by providing a steady flow of oil and lubricating metal engine parts as they work and carrying heat away from the combustion area.
