ABSTRACT:
A device is disclosed for separating hydrocarbon products such as cutting oil from water. The device includes a receiving tank defining a reservoir which receives a mixture of water and oil. The oil floats above the water and thus forms an upper layer in the receiving tank. A skimmer skims the upper layer from the receiving tank and channels the skimmed portion to a pumping chamber. A venturi jet pump then pumps the skimmed portion from the pumping chamber to a settling tank which then separates the oil and water. The skimmer includes floats which vary the depth of the skimmer as a function of the liquid level in the receiving tank.
