A belt skimmer is mounted on tank tops. The unit consists of two (2) pulleys. Care is taken that the bottom pulley is below fluid surface level. The top pulley is connected to a geared drive. An endless belt of polyurethane material rotates on the pulleys. Bottom pulley has a self-tensioning arrangement to compensate expansion of belt over time. Fluid flows slowly over the belt leaving the floating oil on the surface of the belt.
