The Compact 2.5 is the first compact oil separator that separated the oil from the liquid in motion in real time. No special procedures are required for operation, as the separator is self-priming and self-levelling. The Compact 2.5 oil separator suctions the liquid from the tank with a double effect diaphragm pump resistant up to 60 C° with adjustable flow rate from 100 to 300 l/h. Via a Venturi-effect self-levelling system with surface skimming, it suctions the oil on the surface through a cartridge pre-filter to capture the floating solids. The pre-filtered liquid then drops into an oil separator tank, where the oil drops, rising to the surface layer, are separated. The liquid, separated from the oil, drops into the degreasing or pickling tank by gravity, promoting the natural flow of the surface oil towards the take-up point.
