• Precise dimensional restoration — worn components restored to correct specification for reliable, consistent performance
• Specialist hardfacing — applied to key parts including rotors, cones, and housings, targeting the areas most affected by wear
• Tailored surface solutions — weld overlay, composite materials, and thermal spray coatings applied to suit specific vacuum pump requirements, drawing on extensive application expertise
• Thorough testing — all work is supported by testing to ensure optimal performance before the pump returns to service
• Optional non-stick coatings — help prevent internal build-up and scaling, improving efficiency and reducing maintenance requirements

What components does Avweld restore in a vacuum pump overhaul?
Avweld offers precise dimensional restoration of worn components, along with specialist hardfacing of key parts such as rotors, cones, and housings.

What surface treatment options are used in vacuum pump overhauls?
Avweld applies tailored surface solutions including weld overlay, composite materials, and thermal spray coatings, selected to suit specific vacuum pump requirements.

Is overhauled vacuum pump performance tested before return to service?
Yes — all work is supported by thorough testing to ensure optimal performance.

Can non-stick coatings be added during a vacuum pump overhaul?
Yes — optional non-stick coatings are available to help prevent internal build-up and scaling, improving efficiency and reducing maintenance.

Why choose an overhaul over vacuum pump replacement?
An overhaul restores performance, reliability, and service life in demanding operating conditions, often at lower cost and faster turnaround than full replacement.

Vacuum pump overhaul is suited to:

• Vacuum pumps experiencing reduced performance or reliability due to component wear
• Rotors, cones, and housings requiring specialist hardfacing rather than full replacement
• Applications prone to internal build-up or scaling, where non-stick coatings can reduce maintenance
• Operations seeking to extend vacuum pump service life in demanding operating conditions
