Busch R5 RA0100

This Busch R5 RA0100 is a used rotary vane vacuum pump that has been removed from service after functioning as a workhorse in a laboratory or light industrial vacuum system. The R5 series is well known across medical, dental, and laboratory environments for its oil-lubricated design that delivers consistent vacuum performance with low noise and vibration, making it a popular choice for suction systems, vacuum ovens, filtration setups, and general process vacuum needs. Its compact footprint and dual-stage design allow it to reach deep vacuum levels quickly while maintaining stable operation over long duty cycles. The RA0100 model in this size class is typically found supporting benchtop and small-scale applications where reliable, continuous vacuum is required without the need for large industrial infrastructure. These pumps are prized for their durability and straightforward serviceability, with widely available parts and maintenance kits that make them easy to keep running for years. Technicians in laboratories and clinical settings often choose the R5 line because it strikes a practical balance between vacuum strength, footprint, and running cost. This unit is sold as used and in operational condition pulled from a working environment. It is a good fit for buyers looking to replace an aging pump or add backup vacuum capacity to an existing system without paying for new equipment. Buyers should plan for standard incoming inspection and an oil change as part of putting the pump back into service.
