Frequently Asked Questions
What is the Leybold TRIVAC Series?
TRIVAC is Leybold's family of two-stage oil-sealed rotary vane vacuum pumps used in laboratories, research, manufacturing, process systems, and industrial vacuum applications.
What is the difference between TRIVAC B and BCS pumps?
TRIVAC B pumps are standard-duty two-stage rotary vane pumps. BCS models are configured for more demanding or corrosive processes and may use different seals, lubricants, and service parts. Always match the complete model and lubricant configuration.
Do you support older TRIVAC A and C Series pumps?
Yes. Model-specific repair-kit and parts pages for many A, C, and S Series pumps are linked above, even though the primary visual selector focuses on B and BCS models.
Do you sell OEM and OEM-equivalent Leybold parts?
Yes. Vacuum Pump Supply offers genuine Leybold OEM parts and high-quality Vacuum Pump Supply OEM-equivalent repair solutions, depending on the product.
Which oil should I use in a TRIVAC pump?
The correct lubricant depends on the pump model, seal configuration, process, and whether the pump is prepared for hydrocarbon oil or PFPE. Confirm the manual and existing pump configuration before changing lubricant types.
