If properly maintained... yes. But unfortunately they are grease hogs... saddle and tail bearings take a minimum of 3 tubes of grease. They are also hard to source parts for. Most companies just scrap em when they break...
We have had crank arms break and gears go bad in the Chinese “Sentry” units on leases we have purchased. Real Parkersburg and Sentry pumping units are far superior.
These Chinese units don’t hold a candle to all of the old United States made pumping units.
Very true.

I call em grease hogs...lol
Are these Chinese units any good? (Sentry, LS/Lone Star, etc.)
