Blackmer Sliding Vane Pumps

Blackmer’s sliding vane pumps (rotary vane pumps) are designed to handle lubricating fluids and other low-viscosity fluids at low and medium pressures. The unique sliding vane technology allows self-adjustment to mitigate wear while maintaining flow rates.

Blackmer sliding vane pumps are known for their outstanding self-priming and dry-run capabilities, providing uninterrupted operation and reliable performance.

Features & Benefits

Know more about the features & benefits of using Blackmer Sliding Vane Pumps.

Unique technology: self-adjusting for wear, self-priming, dry-running
Ease of maintenance: vanes can be easily replaced without disturbing the system
Excellent performance: high suction lift exceeding 7.6 meters and line-stripping capabilities to empty tanks and pipes of fluid
Renewable and repairable: designed to support low maintenance and low life-cycle costs
Solids handling capabilities: made possible by large displacement and slow internal velocities
Flexibility: handles thin to thick fluids without heating systems
Highly efficient: requires less horsepower/electricity than other pumps

PRINCIPLE OF OPERATION

Blackmer sliding vane pumps use a rotor with sliding vanes to draw liquid into the pump. This rotor is located close to the wall of the cam so that a crescent-shaped cavity is formed on the opposite wall. Each rotor slot contains a sliding vane. As the rotor rotates, centrifugal force, hydraulic pressure, and push rods work together to extend each vane to the casing wall. This creates an expanding cavity on the inlet side – creating a vacuum that pulls liquid into the pump. The liquid is trapped between the vanes and the casing wall. The rotor rotation moves the liquid cavities around to the outlet side of the pump. The vanes are forced back into their slots at the outlet side, decreasing the cavity size and forcing the liquid through the outlet port.
