Sliding Vane Pumps: High Volumetric Efficiency & Consistency, Energy Savings and Reliability by Design

Advanced vane pump designs include motor speed technology, cutting-edge “designed in” features such as a hydrodynamic journal bearing and one mechanical seal. These innovative features serve to further improve the fundamental pumping process in the manufacture of biodiesel. In fact, sliding vane pumps have become the pump technology of choice in biodiesel production plants throughout North America for these same reasons. The secret behind a sliding vane pump’s enviable operational characteristics is the vanes that slide in and out of slots in the pump rotor). The pump’s rotation draws liquid in behind each vane, through the inlet port and into the pumping chamber. As the rotor turns, the liquid is transferred between the vanes to the outlet where it is discharged.  Each vane provides a positive mechanical and hydraulic displacement of the liquid. Vanes are actuated by three forces: (1) centrifugal force from the rotor’s rotation, (2) push rods moving between opposing pairs of vanes, and (3) liquid pressure entering through grooves and acting on the rear of the vanes. Each revolution of a sliding vane pump displaces a constant volume of fluid; variances in pressure have a negligible effect. Energy-wasting turbulence and slippage in the pump are minimized and high volumetric efficiency is maintained.
