Frequently asked questions
What pressure ranges does vacuum technology cover and how do I choose?
Vacuum is conventionally divided into rough, medium, high and ultra-high vacuum, and each range calls for different pumps, seals and sensors. Rough and medium vacuum are obtained with backing pumps, dry or oil-sealed; high vacuum additionally needs a turbomolecular pump, and ultra-high vacuum requires metal flanges, bake-out and low-outgassing materials. Start by establishing the ultimate pressure and the working pressure, then size the whole chain: chamber, pipes, valves, pumps and sensors, because the weakest link limits the result.
Why is a single pump not enough for high vacuum?
A turbomolecular pump cannot exhaust gas directly to atmosphere and needs a backing pump to carry out the initial pump-down and maintain the permitted back pressure. The backing pump in turn must be chosen according to the gas flow of the process, not just the stated ultimate pressure. In large installations a Roots pump is sometimes added between the chamber and the backing pump, which increases the flow rate in the medium range. Each stage has its role, and they are sized together, based on the flow curves.
How do I find a leak in a vacuum system?
Start with an inspection of the seals and connections, then follow the rate of pressure rise after isolating the chamber from the pumps: a linear rise suggests a leak, while one that fades points more to outgassing of materials. For exact location a helium detector is used, which shows the leak rate in mbar·l/s or in Pa·m³/s. The sniffer probe method is applied to objects filled with helium, and the vacuum method to systems under pumping, with higher sensitivity.
Which flange standard should I choose: KF, ISO or CF?
KF flanges are quick to fit and suitable for rough and medium vacuum and, in many cases, high vacuum, at small diameters. ISO-K and ISO-F apply the same principle at large diameters. CF flanges have a metal seal, withstand bake-out and are required for ultra-high vacuum, but the gasket is replaced at every disassembly. Avoid mixing standards without reason, because adapters add interfaces and possible leak points. Choose the standard according to the pressure range, the pipe diameter and how often you take components apart.
What data should I send for a quote on vacuum equipment?
Send the desired pressure range, the chamber volume, the gases and vapours in the process, the connection standard, the operating regime and the available electrical supply. For a replacement, the make, the code on the product nameplate and, if needed, a photograph help. For public procurement, state the CPV code and the requirements from the specification, so that we can prepare a compliant quotation. With this information we can confirm the compatibility between pumps, valves, sensors and flanges before the order, not after delivery. If you do not have all the data, send what you know and we will tell you what is missing.
How long does delivery take and what happens if the item is not available locally or at the supplier?
The lead time is 24–72 h when the item is available locally or at the supplier. For equipment brought in to order, the lead time is usually 1–4 weeks, and depending on the brand and the specifications it may take longer, especially for large-capacity pumps or special configurations. We give you the estimated lead time in the written quotation, and if the specifications change along the way, we tell you from the start whether the lead time changes. For scheduled work, request the quotation in good time. For wear parts and service kits, the exact code speeds up confirmation of availability.
