Sliding Vane Pumps
Blackmer positive displacement pumps have revolutionized the pumping industry with their unique sliding vane technology.
This revolutionary rotary vane design allows the pumps to self-adjust for wear to help maintain flow rates.
This sliding vane pump design creates excellent self-priming and dry-run capabilities, while also providing sustained performance and trouble-free operation.
How it Works
Blackmer sliding vane pumps use a rotor with sliding vanes that draw the 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 as the pumping chamber is squeezed down. Each vane provides a positive mechanical push to the liquid before it.
Vane contact with the chamber wall is maintained 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 the vane grooves and acting on the rear of the vanes.
Each revolution of a Blackmer sliding vane pump displaces a constant volume of fluid. Variance in pressure has minimal effect. Energy-wasting turbulence and slippage are minimized and high volumetric efficiency is maintained.
