PUMPING DEVICE

摘要

The pumping device comprises a central body (1) closed by a couple of headers (2, 3) and is internally provided with a separating disk (4), suitable to divide the inner space into a first and a second chamber (10, 11) separated. The device further comprises a shaft (5) passing through the said body (1) and the said headers (2, 3) in an eccentric position and connected at one end to an actuator (200); a first and a second impeller (6, 7) arranged respectively into the said first and second chamber (10, 11) and integral to the said shaft (5). The first and second chamber (10, 11) are connected to a recycling duct (16) of the suctioned, mixed, heated and pumped material, suitable to make the flow of the material more homogeneous during the steps of mixing and heating.
