Rotary vane pumps are essential in pressrooms, binderies, packaging, and many other industrial applications. They provide the vacuum or compression needed to move, pick, or lift materials. When a pump goes down, so does the whole operation—often due to failed vanes. Vanes are critical to pump performance, and replacing them creates costly downtime. Saving a little on cheap vanes can cost you a lot later. Here’s why:
Tested across multiple graphite formulations and manufacturers, low-quality vanes have been shown to wear out up to 4× faster than quality originals.
Faster wear generates more carbon dust, which clogs filters and forces more frequent filter changes and maintenance.
Poor material and finish increase friction, raising operating temperatures. Heat accelerates wear on vanes, bearings, and seals, and can degrade oil more quickly.
Cheap graphite is often too hard and not resilient enough to slide smoothly on the stator, causing premature wear of the stator and rotor surfaces.
Tight tolerances are critical. Oversized vanes can seize and fracture; undersized vanes leak, reducing vacuum and overall performance.
Every vane has a minimum service height that must be monitored. Low-quality vanes reach that limit much sooner, demanding checks far more often—and missed checks lead to failures.
When brittle, low-grade vanes chip, sharp fragments can score the rotor and stator. In severe cases, the pump becomes uneconomical to repair and must be replaced.
