A standard rotary vane oil sealed vacuum pump should have its oil replaced at least every four to six months to keep it at peak performance. Rotary vane pumps are also supposed to receive regular checks in between replacements, to monitor for potential issues.
Yet, most shared lab spaces struggle to effectively implement this maintenance consistently. As time goes on, the neglect adds up and many oil pumps end up operating with drastically reduced capacity as a result. Others fail altogether, causing lab operations to come to a complete standstill.
But even in the event of pump failure, your lab still has obligations to fulfill. Deliverables are still required and time-sensitive materials continue to deteriorate on the shelf. Ultimately, the downtime translates to lost funding and resources.
Because of this downtime, an initially lower-cost oil pump can wind up being an expensive hassle in the long run. To sidestep the problems of ongoing maintenance and risk of failure due to oil contamination, upgrading to dry pumps may be a good choice for your lab’s overall productivity.
