Floating Suction Units are used within storage tanks, especially for petroleum, aviation heating oil and petrochemical products which are required very high purity requirements of the substances. It delivers cleaner product by absorbing the fluid closest to the surface. With that operation, it is prevented that the settled water and residuals at the bottom of the tank from being sucked in. Floating Suction Pipe always floats on the surface of the liquid, the inlet to the pump is held in the clean dense product regardless of the constantly changing liquid level. For tanks with floating roofs, large bore roof skimmers move with the roof to drain away unwanted liquid. As the bottom section of the storage tank is contaminated with dirt, sludge or rainwater, it is recommended to such the clean product from the higher level. Thanks to the pontoons that are manufactured for this purpose, Floating Suction Unit floats and delivers cleaner product by absorbing the fluid closest to the surface.
