We have 2 JD HD 200 sprayers and both have centrifugal pumps and rarely have a problem. Yes the seal will wear out but it only takes about a half hour to change and they normally last a few years. Like Andy said, if you are spraying a lot of paints, you probably should consider diaphragm. Some herbicides can be rough on seals, but knock on wood, we have not had any problems.
