PureTech has never disappointed its customers, consistently providing high-quality, high-performance, and cost-effective equipment. This is also our mission: to provide our customers with better products and services.

Key Considerations and Best Practices for Using Vacuum Pump Systems

To achieve optimal results, specific operational protocols must be followed.

1. Achieving and Measuring the Target Vacuum:

• The ultimate vacuum level is paramount. The process must continue until a stable, deep vacuum is achieved and held for a specified duration (as per manufacturer guidelines, often 24-72 hours) to ensure all moisture is removed.
• Use of accurate vacuum gauges is essential. A Pirani gauge is ideal for measuring medium to high vacuum levels.

• The entire setup—the transformer tank, all valves, flanges, hoses, and connections—must be absolutely leak-tight. Even a small leak can prevent the system from reaching the required vacuum depth and prolong the process indefinitely, wasting time and energy. A thorough leak check is a mandatory step before and during the evacuation process.

• Selecting the right pump size is crucial. The pump must have sufficient displacement (CFM or m³/h) to handle the large volume of the transformer tank and the outgassing from the insulation. An undersized pump will lead to unacceptably long processing times. PureTech offers a range of models to match the specific requirements of any transformer, from distribution units to large power transformers.

• As the pump evacuates large volumes of water vapor, this vapor can condense inside the pump oil, contaminating it and reducing pumping efficiency. PureTech pumps are equipped with effective gas ballast valves, which help to prevent this condensation by allowing a small, controlled amount of dry air into the compression chamber, enabling the vapor to be expelled before it condenses. For heavy moisture loads, an external condenser or cold trap is highly recommended to protect the pump.

**Why PureTech is the Trusted Partner for Your Critical Operations**
