Main vacuum setup consists of a 13 hp motor with electric start. The pump was pulled off a manure spreader. It can easily drain a 55 gallon drum in seconds.
A sediment bowl and filter help prevent oil from reaching the vacuum pump.
The vacuum tank is a re-purposed propane tank. It handles the vacuum well. It is pressurized to push the oil into the settling tanks. The hoses use cam lock fittings making it quick. All hoses and fitting are vacuum and pressure rated for the application.
