Pump sleeves/liners
The protection of pump sleeves is a specialised application of Avweld’s skills and unique technical capacity, utilising the advanced Laser Cladding, HVOF and PTA Tungsten Carbide processes.
The protection of pump sleeves is a specialised application of Avweld's skills and unique technical capacity, utilising advanced Laser Cladding, HVOF, and PTA Tungsten Carbide processes. These technologies are complemented by precision diamond grinding and super-finishing, ensuring the exact surface finish and exceptional wear resistance required for vacuum pump applications.
Why Pump Sleeve Protection Matters
- Advanced coating technologies — Laser Cladding, HVOF (High Velocity Oxygen Fuel), and PTA (Plasma Transferred Arc) Tungsten Carbide processes applied specifically to pump sleeve protection
- Precision finishing — diamond grinding and super-finishing deliver the exact surface finish vacuum pump applications demand
- Optional plasma-sprayed ceramic coatings — for applications with specific requirements, plasma-sprayed chrome oxide ceramic coatings can be applied to further enhance performance
- Extended packing material lifespan — careful material and surface finish selection maximises component life while also extending the life of packing materials
- Significant reliability improvement — with wear reduced to minimal levels, pump efficiency improves significantly, and reliability can increase to three to four times that of unprotected units
- Outstanding corrosion resistance — these solutions provide strong corrosion resistance, with elevated operating temperatures posing no limitation to performance
Applications
Pump sleeve protection is suited to:
- Vacuum pump applications requiring precise surface finish and wear resistance
- Pumps operating in corrosive environments
- Pumps operating at elevated temperatures where standard protection methods may be limited
- Operations seeking to significantly extend pump component and packing material life
What processes does Avweld use to protect pump sleeves?
Avweld uses Laser Cladding, HVOF, and PTA Tungsten Carbide processes, complemented by precision diamond grinding and super-finishing, and optional plasma-sprayed chrome oxide ceramic coatings for specific requirements.
How much does pump sleeve protection improve reliability?
Protected pump sleeves can achieve reliability three to four times that of unprotected units, as wear is reduced to minimal levels and pump efficiency is significantly improved.
Does pump sleeve protection affect packing material lifespan?
Yes — careful selection of materials and surface finishes not only maximises the life of the pump sleeve itself but also extends the lifespan of packing materials.
Can protected pump sleeves handle high operating temperatures?
Yes — these protection solutions offer outstanding corrosion resistance, with elevated operating temperatures posing no limitation to performance.
Is pump sleeve protection suitable for vacuum pump applications specifically?
Yes — the precision diamond grinding and super-finishing processes are specifically noted as delivering the exact surface finish and wear resistance vacuum pump applications require.
