I worked on a washer system that pre-sprayed a product. Sump was about 3ft deep 16in X 16in box. Pump was a shaft drive oil pump from a big block Chevy. Left side sprayer would lose pressure. I figured plugged screen by tip or plugged tip. I would shut down the system and clean then fire it back up 20 minutes later. Everything back to normal. Could never see any particles though. But it was always the left side.
This began happening daily. Finally one day I noticed the problem was always developing 3-4 hrs into a shift. So the next time it happened, I lifted the pump out of the hole. The intake screen on the pump was collapsed and plugged.
When I was shutting the machine down to clean the tips, that 20 minutes would allow a bunch of crud to fall off the suction screen. Enough crud fell off, that the pump would run another couple hours to finish the shift. Over night the rest of the crud fell off and the cycle started over the next day.
The reason it was always the left side was the tips were offset and those were 2 inches higher than the right side so they took just a touch more pressure to work. As it began to starve those were the first to fail.
The screen on the pump had 1/16th inch holes. Just small enough to keep chunks out of the oil pump gears. The particles were fine that should have easily passed through the pump and screen but for some reason they would build up.
I lifted the pump up higher in the sump to give more room on the bottom for the crud to settle.
