Vacuubrand manufactures a comprehensive range of laboratory and instrumentation vacuum pumps, gauges and controllers for both coarse and fine vacuums. Vacuubrand’s first priority is to offer sophisticated equipment which meets the highest quality, professional standards expected of a modern laboratory. For example, ‘intelligent pumps’ make lab work more efficient, allowing chemists and technicians to focus their attention on other tasks.
They engineer and produce almost all of their pump and controller components at their facility in Germany. This enables Vacuubrand to quickly respond to the wide variety of demands from different laboratories, offering tailor-made solutions, and also ensures a consistent approach to the quality of their design and manufacturing processes.
Vacuubrand relies on a range of cutting-edge technology and machine tools to produce a large selection of products, including rotary vanes, diaphragm pumping units, chemistry vacuum systems, vacuum gauges and controllers, as well as valves and components of the innovative VACUU-LAN local vacuum network.
Vacuubrand’s varying stage pumps feature a gas ballast valve that helps preserve pump performance when working with condensable vapours. Pumping chambers are also hermetically separated from the drive space, ensuring ample longevity. Most importantly, Vacuubrand diaphragm pumps are oil-free, reducing service demands, eliminating water waste from water-jet aspirators and the contaminated waste oil disposal of rotary vane pumps.

Vacuubrand pumps achieve their outstanding performance through a high pumping chamber volume. Flexible FKM double diaphragms featuring fabric reinforcement ensure durability. Oil-free pump operation without any sliding components in the gas path keeps the pump free from abrasion during normal operation, improving longevity and eliminating particulate impurities.

Vacuubrand’s chemistry diaphragm pumps are appropriate for such locations because they are highly resistant to chemicals, oil-free, have no sliding surfaces and the expansion chamber is hermetically sealed against the drive zone. ATEX chemistry vacuum systems with solvent recovery provide a safe, convenient vacuum while protecting the environment. They are also supported by an ATEX vacuum gauge with excellent corrosion resistance for long-term stability.

An expert development team and integrated production process, along with cutting edge machinery and automatic testing equipment, give Vacuubrand a high level of flexibility and control over manufacturing. In OEM applications, Vacuubrand adapt their pumps to suit a variety of individual installation requirements. Everything from motors to electrical interfaces are considered, with the option of integration with existing equipment control wiring.

Vacuubrand’s rotary vane volume flow rate is specified at atmospheric pressure, as is customary with PNEUROP®. For process efficiency, however, the high volume flow rate of Vacuubrand pumps under process conditions, as well as a consistently high volume flow rate over a wide pressure range, is crucial for a variety of applications.

In addition, the BVC Professional features a non-contact liquid level sensor and self-closing quick couplings (4l PP bottle version). All systems are available with either a vacuum resistant, autoclavable 4l PP bottle, or with a 2l borosilicate glass bottle, ideal for working with aggressive disinfectants such as chlorine bleach. All product versions can have an additional hand control connected immediately.

Many laboratory applications require electronic vacuum controls which are able to constantly adapt the pump´s volume flow rate to process requirements. The maximum volume flow rate of the unregulated pump can be altered in various ways. By turning the pump on or off (with the CVC 3000 controller and module VMS-B) by opening and closing an in-line solenoid valve (CVC 3000) or by continuously changing the pump´s motor speed (VARIO® pumps in connection with CVC 3000).

Versatile and easily upgradable vacuum modules are available for a variety of workplace outlets. All components are available for either new laboratories, existing or renovated laboratories. The modules are suitable resistant to chemicals, and have built-in check valves to ensure that adjacent applications do not contaminate or interfere with one another.

Vacuubrand Components and subassemblies are available in stainless steel, aluminium, brass or plastic. Vacuubrand offer elastomer seals constructed from NBR and FKM, as well as metallic seals constructed from aluminium or indium. Vacuubrand also have a wide variety of resilient connecting elements and small-flange components, that serve most vacuum system needs.

Front mounted inlet catch pots keep the pumps clean and dry, and are easily accessible. The Vacuubrand VARIO® regulation system provides vacuum on demand whenever necessary. The central control unit determines the power required, and controls the speed of the individual pumps accordingly during the entire process. This maximizes energy savings and reduces maintenance requirements. The unique ability to service individual pumps during operation leads to a plant availability of 24 hours, 7 days per week.
