Why Rebuild Your Leybold D16B Vacuum Pump?
Over time, vanes, seals, gaskets, valve components, shaft sleeves, and internal wear parts degrade from normal operation. Worn components can contribute to oil leaks, reduced vacuum levels, increased operating temperatures, contamination, noise, and longer pump-down times.
A complete rebuild using quality OEM-equivalent replacement parts can help restore performance while extending the life of your Leybold D16B vacuum pump.
