Vacuum Pump Units

Q: What makes the Vacu² system different from other vacuum pump units?

The Vacu 2 system is a specialized multi-stage vacuum process designed to efficiently evacuate air from the shot sleeve and mold cavity in die-casting systems. It is particularly beneficial in applications involving large-volume die-casting, where rapid and controlled degassing of the mold cavity is crucial for achieving high-quality components with superior mechanical properties.

Powerful and robust

Reliable vacuum systems are an essential part of many production processes. Different pump technologies and configurations are used depending on the specific requirements.

Vacuum pump units are available in standard versions, but also offer individually configurable options, ensuring they are the perfect match for your process.

Suitable vacuum pump units for every application

In many applications, it is not possible to generate the required vacuum within the available time using a single vacuum pump. This is the case when large quantities of gas need to be handled or when a particularly deep vacuum ≤ 10^-3 hPa (mbar) is necessary. Not every vacuum pump can operate from atmospheric pressure, so an additional backing pump – also known as a roughing pump – is required to handle the differential pressure.

The most frequently used vacuum pump units are our turbomolecular vacuum pump units and our vacuum booster pump units.

Multi-stage die cast vacuum process

Our multi-stage vacuum process Vacu² is a vacuum pump unit configured to suit a specific application: In die-casting large-volume structures, rapid and controlled degassing of the mold cavity is crucial for ensuring reproducibly high-quality components.

However, the planning goes beyond vacuum pump performance. It also includes documentation, monitoring, and control of the process before, during, and after the shot.

FAQ

What are typical areas of application for vacuum pump units and why is an additional backing pump needed?

Vacuum pump units are used in applications like space simulation, electron beam welding, metallurgy, glass coating, and solar technology. In some cases, an additional backing pump is required to handle large gas volumes or achieve high vacuum levels (≤ 10^-3 hPa (mbar)), as a single vacuum pump cannot generate the required vacuum conditions or handle the differential pressure from atmospheric pressure.

What aspects should be considered when choosing a vacuum pump unit?

When selecting a vacuum pump unit, various factors must be considered, including availability, price, resources, energy efficiency, risk management, redundancies, and operating costs. Additionally, application-specific requirements such as contamination avoidance should be taken into account.

Which vacuum pumps can be used in vacuum pump units?

Basically, any vacuum pump technology can be combined with another.

We mainly use:

Rotary vane vacuum pumps, with one or two stages
Screw vacuum pumps
Scroll vacuum pumps
Diaphragm vacuum pumps
Vacuum boosters
Turbomolecular vacuum pumps
