Automatic Oil Filter / Water Separator for the Harvest Right JB Industries Vacuum Pump & Oil Filter System

EpicenterBryan's recommended parts list (listed below) for the Automatic Oil Filter / Water Separator for the Harvest Right Freeze Dryer JB Industries Vacuum Pump / Oil Filter System.

EpicenterBryan says, "I built a filter system to clean the oil and separate water at the same time for my Harvest Right JB Pump. The best part is that I don't have to drain the oil, and it can happen while the pump is running!"

"The system is simple. It uses a diesel fuel filter that has a built in water separator. There is also a gas / diesel fuel pump that pulls oil through the filter, and returns it to the vacuum pump. The oil originates from where oil is normally drained out of the vacuum pump (to filter), and it is returned to the pump where you would normally fill with oil. There are a bunch of fittings involved, and also some clear vinyl tubing. I've run the system for about 3 months and the vinyl has had no issues having oil in it the whole time."

"I discovered that the re-circulation pump doesn't need to run the entire time, so I added a programmable timer to control how long it's on and how long it's off."

"If you are going to do something like this, I'm sure it will void your pump warranty. This project is for the experimenters out there who want to take the risk."

"I've now run over 30 batches and will open the pump when I hit 40 batches to see how clean it is inside... That's twice as many batches as they recommend between cleaning the inside. Time will tell."
