Below is an example of our repair capabilities: This particular diffusion pump body was going to be thrown out. The heater was left turned on without a vacuum in the pump for more than one year. As can be seen, the boiler was severely damaged and the remaining oil had congealed to the point that it was like a hard expanded sponge, which filled the boiler, vapor jet and drain tube.

Although this was not a typical repair, the repair cost was less than a new pump body. Even though extensive cleaning was necessary with a variety of chemicals to remove all the burned and hardened oil and a new boiler and drain tube had to be fabricated, this Precision Neon Laboratories Ultra-Vac® Diffusion Pump now provides high vacuum service once again.
