Should You Repair or Replace a Busch R5 RA 0305D?
Many Busch R5 vacuum pumps can be economically repaired if faults are identified early.
However, replacement may be the more cost-effective solution if the pump has:
• Severe internal scoring
• Damaged rotor components
• Bearing Failure
• Heavy wear
• Mechanical pick up
VacAir can advise whether a service is sufficient, a workshop overhaul is viable or a replacement pump would minimise downtime and reduce long-term operating costs.
We can also supply refurbished replacement pumps subject to availability.
