Keeping vacuum pumps cool during summer months

The Busch Group outlines the measures to take to keep vacuum pumps operating reliably in the summer months

As temperatures rise, the performance and durability of vacuum pumps can be significantly affected. Maintaining a cool environment for these devices is critical, as most are built to function effectively in ambient temperatures of up to 40°C. Overheating can lead to accelerated oil degradation, increased maintenance costs, and potential equipment failure, interrupting manufacturing and causing expensive repairs.

The importance of keeping pumps cool
When vacuum pumps operate in ambient temperatures that are hotter than they are designed for, the oil degrades faster compared to a pump running in a cool environment. This means the vacuum pump oil will need to be changed more often, increasing maintenance costs. If plant room temperatures exceed 40°C, vacuum pumps can overheat, potentially leading to a breakdown.  Not only can this disrupt manufacturing processes and lead to lost revenue, but it can also result in costly repairs.

Plant room ventilation – natural v forced
Natural ventilation from vents and louvres relies on air movement due to wind or convection to be effective, so its performance can vary depending on the temperature and wind speed. During periods of warm weather, it is usually not possible to achieve the high ventilation flow rates necessary with natural ventilation alone, unless significant portions of plant room walls are open or vented.
