Shop Sliding Vane Pumps

Sliding vane pumps are positive displacement pumps built around a beautifully simple mechanism: vanes slide in and out of slots in a rotating rotor, drawing liquid into chambers formed between the vanes and carrying it from inlet to outlet. Blackmer® invented the technology in 1903, and its defining advantage endures — as vanes wear, they self-adjust outward to maintain flow rates, instead of losing performance the way fixed-clearance pumps do. Sliding vane pumps self-prime, deliver strong suction lift, strip lines and tanks clean for maximum product recovery, run dry safely, and handle everything from thin solvents and fuels to liquefied gases that make other pumps cavitate.
