VACUUBRANDs aluminum design diaphragm pump is a perfect match for many applications in the laboratory and operations because it is oil-free and whisper quiet, and because it requires so little service. Diaphragms have especially long lives and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps achieve their distinctively high performance from high pumping chamber volume relative to the minimal dead space. Highly flexible FKM double diaphragms with fabric reinforcement ensure an extremely long diaphragm lifetime. The pumps operate absolutely oil free and do not have any sliding components in the gas path. In normal operation they are completely free of abrasion. Besides contributing to the long service intervals the lack of abrasion also eliminates most of the particulate impurities frequently generated inside of scroll or piston pumps. This makes VACUUBRAND diaphragm pumps the right choice for clean applications.

Typical applications for chemistry diaphragm pumps include evacuating chemically aggressive gases and vapors from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators. Chemistry diaphragm pumps from VACUUBRAND feature uncompromising chemistry designs. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust and very tolerant to condensates. Our two-, three- and four-stage pumps also have a gas ballast valve that provides continuous purge with minimal impact on ultimate vacuum when working with condensable vapors. Pumping chambers are hermetically separated from the drive system ensuring long lifetimes of mechanical parts. Most importantly, diaphragm pumps are oil-free, for vastly reduced service demands compared with oil-sealed pumps. They eliminate the cost of water and its contamination well-known from water-jet aspirators, and the waste-oil disposal of rotary vane pumps.

Rotary vane pumps are used whenever it is necessary to have a process vacuum of up to 10-3 mbar. VACUUBRAND rotary vane pumps are high-performance, yet compact, and can be equipped with an extensive line of VACUUBRAND accessories. They have an innovative lubrication system with a built-in oil pump and have a large oil volume. This extends oil change and service intervals and protects the pump at start-up. The effective gas ballast feature, with its high-flow gas ballast, provides high vapor pumping capability for water and solvents. VACUUBRAND rotary vane pumps volume flow rate is specified at atmospheric pressure, as is customary with PNEUROP. For process effiency, 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 the key to your satisfaction in real-world application. After switch-off the aggregate is vacuum-sealed to protect your application from undesired venting and oil back flow.constriction-free vapor pathway allows high volume flow rates, even when close to the ultimate vacuumhigh tolerance for water and solvent vapors, because of the high-volume gas ballastquiet running and excellent ultimate vacuum, even with gas ballastactive corrosion protection: Oil cycle closes vacuum-tight against the intake of corrosive gases and oil impurities into the reservoir when shut downnew design lubrication circuit, and large usable oil volume provides extended oil change and service intervalscompact design, low weight and easy service with telescopic design

The compact BioChem-VacuuCenter offers the perfect solution for safe, sensitive and efficient aspiration of supernatants in all application areas. The BVC basic is intended for connection to an external vacuum source. The BVC control and the BVC professional are equipped with a high performance, chemically resistant diaphragm pump. The vacuum level and thus the suction force at the hand control can be sensitively adjusted via a touch panel. 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 either with a vacuum-resistant, autoclavable 4l PP bottle or with a 2l borosilicate glass bottle, e.g., for working with aggressive disinfectants such as chlorine bleach. All versions are ready for connection of a second hand control.

State-of-the-art vacuum gauges for laboratory and industrial operation have to meet high standards in terms of gauge head resistance to chemicals, reliability in rugged applications and operator-friendly interfaces. VACUUBRAND has a comprehensive range of electronic measuring instruments for the range of atmospheric pressure to 5 x 10-9 mbar. A lot of applications in the laboratory call for electronic vacuum control, that is, constantly adapting the pumps volume flow rate to process requirements. The maximum volume flow rate of the unregulated pump can be changed in various ways:by cyclically turning the pump onoff (with CVC 3000 controller with module VMS-B)by cyclically openingclosing an in-line solenoid valve (CVC 3000) orby changing the pumps motor speed continuously (VARIO pumps in connection with CVC 3000)

Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in these MZ 2 series pumps that are in contact with pumped media are made of aluminum, stainless steel and selected plastics, allowing a wide range of applications for non-corrosive gases. The two-stage construction provides the advantageous combination of high pumping speed and an ultimate vacuum down to 4 mbar. The highly flexible fabric-reinforced double diaphragms made of FKM provide high reliability and extended operating life. The NT-series features further improved performance data and compact design.Performance features contamination-free pumping and evacuationhigh flow rate even near ultimate vacuumgood ultimate vacuumwhisper quiet and very low vibrationexceptionally long diaphragm life and maintenance-free drive system for low lifetime costs

At VACUUBRAND, we make our own valves and components and inspect them carefully before shipment to ensure integrity. Our wide range of vacuum valves and small-flange components can be used alone or in combination, in the most simple or complex vacuum systems. Our components are appropriate both for connections to VACUUBRAND pumps and for all valves and components with DIN 28403 (ISO 2861-1) small flange (KF) dimensions. Many components and subassemblies are available in stainless steel, aluminum, brass or plastic. We offer elastomer seals made of NBR and FKM as well as metallic seals made of aluminum or indium. We round out the line with a great variety of resilient connecting elements and small-flange components that serve most vacuum system needs.
