Avoiding Cheap Rotary Pump Vanes

Rotary vane pumps are a necessity for most pressrooms, binderies, packaging operations, and many other industrial applications. They provide the vacuum or compression needed to move, pick or lift products and materials. When a pump goes down, so does the whole operation. One of the main reasons for this to occur is a failure of the vanes inside the pump. The vanes are essential for the pump to function properly and replacing them can create unnecessary downtime. By saving money on cheap vanes, you're actually costing yourself in the long run. Here's why:

	1. They Wear Out Quickly The vanes we provide have been tested by creating them from different types of graphite and made by different manufacturers. It’s been proven that cheap, low-quality vanes wear out 4 times faster than the original vanes.
	2. They Increase the Pump's Running Costs Low-quality carbon vanes have a higher wear rate. This produces more carbon dust which means you will need to change filters more often.
	3. They Increase Pump Running Temperatures Low-quality carbon vanes have a higher wear rate. This produces more carbon dust which means you will need to change filters more often.
	4. They Wear Out the Pump Cheap graphite is normally hard and does not possess sufficient resilience, which is required for the vane to smoothly slide on the stator. Therefore, hard graphite will cause premature wear to the surfaces of the stator.
	5. They Reduce the Pump's Efficiency The way that cheap vanes are made means that it is possible to achieve the exact dimensions and high tolerances that are required to obtain the best performance. If a vane's dimensions are larger than they should be, it would normally break down. If the dimensions are smaller, it leads to poorer pump performance and lower vacuum.
	6. They Increase the Risk of the Pump Breaking Down Every vane has a minimum allowed height that is determined by the manufacturer. It is recommended by the manufacturers that this height is regularly checked. If you fail to do this and allow the pump to run on vanes that are shorter than the allowed size, it will inevitably break down. The problem with low-quality, cheap vanes is they need to be measured 4 times more often than high-quality vanes, and you are more likely to miss a measurement sooner or later.
	7. They Can Cause the Pump to Completely Fail, Leaving You with the Cost of a New Pump When low-quality vanes break down, sharp chunks of hard graphite break off and cause irrecoverable damage to the pump by scratching the surface of the rotor and stator. This normally means the pump will have to be replaced.
