Melling has been a leader in oil pump technology for over 70 years and used that experience to design, engineer, and manufacture these new water pumps! Melling Water Pumps Are Assembled and Tested in Jackson, Michigan by YOUR Melling Team with key advantages.

Oil pumps are mechanically simple devices that spend their entire lives bathed in fresh flowing oil. Usually if pressure becomes a problem it's wear in other areas, generally crank bearings. Prophylactically replacing an oil pump makes about as much sense IMHO as prophylactically replacing crankshaft.

You can change engine oil pump if it starts showing signs. It should last somewhere between 60,000 and 70,000 miles in a properly maintained and regularly serviced vehicle. In the end, it's a DIY task if you know how to replace an oil pump but go to an auto repair shop if you are not confident.
