Single-stage centrifugal pumps with closed impeller, ISO 2858 & 5199
Single-stage centrifugal pumps with closed impeller for thermal oil.
TCD/SP pump series has been especially designed to handle vegetable oils.
The design varies from the standard TCD series only in the mechanical seal area; an intermediate cover has been added beyond the mechanical seal. This intermediate cover should be connected to a reservoir containing oil compatible with the pumped fluid. This device avoids that, in case of mechanical seal breakdown, air can enter into the pump irreparably oxidating the pumped oil or that oil of bearings enter into pumping circuit or vice versa.
