Vacuubrand Diaphagm pumps

Chemistry diaphragm pumps and -pumping systems

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.

• PTFE sandwich diaphragms and valves made of perfluoro elastomer or PTFE
• internal tubing and fittings made of PTFE/ETFE/ECTFE compounds
• exceptional diaphragm lifetimes with ultra-durable PTFE sandwich design
• head cover and clamping disc made of fluoro compounds with stability core for unsurpassed long-term performance
• very long service intervals for low lifetime cost-of-ownership
• patented new drive system for extra quiet, ultra-low-vibration operation (NT)
• patented new valve mounting system to simplify service access (NT)
• smooth surfaces for easy cleaning (NT)
• new sealing system provides reduced leakage rates for improved ultimate vacuum (NT)

Vacuubrand Pump

Vacuubrand Rotary vane pumps and pumping units, chemistry-HYBRID^TM 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 vacuum
• high tolerance for water and solvent vapors, because of the high-volume gas ballast
• quiet running and excellent ultimate vacuum, even with gas ballast
• active corrosion protection: Oil cycle closes vacuum-tight against the intake of corrosive gases and oil impurities into the reservoir when shut down
• new design lubrication circuit, and large usable oil volume provides extended oil change and service intervals
• compact design, low weight and easy service with telescopic design
