Ion Pumps

Ion Pumps

Duniway Stockroom has been rebuilding ion pumps for over 35 years, and we have seen and rebuilt nearly every brand and type of ion pump made. Each pump is processed in our ion pump manufacturing facility and receives the same treatment as our newly manufactured pumps. This attention to detail means that your rebuilt ion pump will have the same performance as a new ion pump at a fraction of the cost. We stand behind the products that we rebuild by offering a full one-year warranty on defective parts and workmanship for all rebuilt ion pumps.

Mechanical Pumps

Mechanical Pumps

Duniway Stockroom's dedicated rebuilding shop has over 35 years of experience, giving us unequalled experience in the repair of oil-sealed rotary vane pumps, dry scroll pumps, rotary piston pumps, and roots-style pumps and blowers. Our rebuilt pumps perform as well as our new pumps, and we stand behind our work with a full one-year warranty on defective parts and workmanship.

Turbo Pumps

Turbo Pumps

Turbo pumps are an expensive investment, and given the proper care, they can last many years. Duniway Stockroom rebuilds a large number of oil-lubricated and permanently-greased ceramic ball bearing-suspended pumps, as well as select magnetically levitated pumps. Repair of your pump involves disassembly, cleaning, replacement of high-speed bearings, and dynamic balancing of the rotor. All turbo pump rebuilds come with a full one-year warranty on defective parts and workmanship.

Diffusion Pumps

Diffusion Pumps

Diffusion pumps offer the highest pumping speed to cost ratio, and Duniway tech- nicians are repair experts. Whether your pump has oxidized from years of use, has been dumped to atmosphere, has a burned out heating element, or has a non-functional cooling line, we can return your tired pump to new pumping condition. During the repair process, the pump will be completely cleaned, helium leak-checked, and painted, leaving the exterior looking as good as the interior. All diffusion pump rebuilds come with our full one-year warranty on defective parts and workmanship.
