I've got car washes and over the years I've converted from Cat to Arimitsu pumps. No problems with the pumps for several years.
First I'll admit that changing the oil and even checking the oil in the pumps is not on my priority list. In fact, I've never changed the oil in any of my Arimitsu pumps. My fault I freely admit.
I've got a pump that I installed about 6 years ago in my busiest self serve car wash bay. Over the weekend that pump stopped working. In "stopped" I mean the thing seized up. Wouldn't turn over and it burned up the belt from the electric motor. The attendant simply closed the bay and let me worry about it on Monday.
I got to the wash and sure enough, the pump wouldn't rotate using my hand to force the pulley. I checked the oil level in the crank case and it was bone dry. No oil. That's not good and I thought I had burned up the pump. I then added some oil and worked the pulley back and forth with a cheater bar and almost immediately the pump loosened up and began to rotate. I then added oil up to the full mark, installed a new belt and turned on the motor. The thing took off and ran like a champ. Now the pump is loose again and runs and runs and runs. No problems.
Lesson? Yeah, check and change the oil in pumps more often than I do/did. Also, keep the belts somewhat loose so that when things "seize" the belt burns up on the motor pulley and not something worse or more expensive.
