FAQs

Oil-lubricated pumps can achieve higher vacuum levels and operate more quietly. Dry pumps, on the other hand, require less maintenance and carry no risk of oil contamination. The selection is made according to the application.

Suction capacity (m³/hour), the achievable vacuum level, operating temperature, energy consumption, maintenance cost, and the cleanliness of the environment are the most critical criteria.

If periodic maintenance is not carried out, pump performance decreases, the oil becomes contaminated more quickly, bearing and vane wear increases, and the system becomes unable to maintain pressure. This leads to malfunctions and downtime.

Oil contamination, clogged filters, air leaks, vane wear, or motor inefficiency are common causes. System connections should also be checked.

An oil change is recommended after an average of 2,000–3,000 operating hours. This interval may be shorter in intensive or dusty environments.

An increase in noise may indicate issues such as vane wear, bearing failure, insufficient oil, or motor imbalance. It is not considered normal and should be inspected.

Industrial models are suitable for long-term operation; however, system temperatures must be monitored, oil levels must be maintained, and manufacturer limits must not be exceeded.
