VACUUBRAND MD 4 VARIO Select Diaphragm Pump Ultimate Vacuum 1 mbar (0.75 Torr) Maximum Pumping Spee (more)d 3.4 CFM at 60Hz Number of Heads/Stages 4/3 Features - VACUU-SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory - Extraordinary diaphragm life for minimum operational and servicing costs - Contamination-free pumping and evacuation - Excellent ultimate vacuum and TURBO-MODE for use as backing pump for turbo pumps This three-stage diaphragm pump is an excellent solution for continuous, oil-free pumping of non-corrosive gases to a vacuum level as deep as 1 mbar. All wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of applications with non-corrosive gases. The MD 4 VARIO select continuously adapts its motor speed to hold the desired vacuum level. That means the pump is whisper-quiet and generates ultra-low vibrations and has high leak tightness. The highly flexible fabric reinforced double FKM diaphragm is ideal for extended operating life. The VARIO design includes the variable speed pump and the VACUU·SELECT vacuum controller with external gauge head. The demand-responsive motor speed control on VARIO models further extends the already long lifetimes of diaphragms and valves. These three-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases at demanding vacuum conditions. They are especially suitable for applications requiring high volume flow in physics and analytics. The low ultimate vacuum makes these an attractive alternative to rotary vane pumps. Typical uses are as backing (roughing) pumps for turbomolecular drag pumps, for degassing of viscous media, as well as for exhaust gas analytics. Additionally, the VARIO model provides vacuum control by precise adjustment of the diaphragm pump´s motor speed to process requirements. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation. For equipment manufacturers customized versions are available. Depending on the application, the demand-responsive motor speed control of VARIO models further extends the long diaphragm life for which VACUUBRAND pumps are well-known. In addition, it provides an even higher pumping speed and enables precise vacuum control. INCLUDED: The VACUUBRAND MD 4 VARIO Select Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND MV 2 VARIO Select Diaphragm Pump Ultimate Vacuum 0.3 mbar (0.2 Torr) Maximum Pumping Spe (more)ed 1.9 CFM at 60Hz Number of Heads/Stages 4/4 Features - VACUU-SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory - Automatic boiling point detection and adjustment of the vacuum for short process times - Extraordinary diaphragm life for minimum operational and servicing costs - Contamination-free pumping and evacuation - Excellent ultimate vacuum, and even better ultimate vacuum with VARIO version in TURBO-MODE for use as backing pump for turbo pumps Four-stage diaphragm pumps - like the MV 2 VARIO select - are an excellent solution for continuous, oil-free pumping of non-corrosive gases at fractional millibar vacuum levels. Wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. The MV 2 VARIO select continuously adapts its motor speed to hold the desired vacuum level. That means the pump is whisper-quiet and generates ultra-low vibrations, and has high leak tightness. The highly flexible fabric-reinforced double FKM diaphragm is ideal for extended operating life. The VARIO design includes the variable speed pump and the VACUU-SELECT vacuum controller with an external gauge head. The demand-responsive motor speed control on VARIO models further extends the already long lifetimes of diaphragms and valves. Four-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases under the very high vacuum demands of applications in physics and analytics. They generate a clean vacuum as they are designed without any sliding seals. Hence abrasion or dust are excluded that might creep back into the application. Due to the outstanding ultimate vacuum these pumps are often used as an alternative to rotary vane pumps. A typical application is the use as backing pump for turbomolecular drag pumps. Additionally, the VARIO version provides vacuum control by precise adjustment of the diaphragm pump's motor speed. Depending on the application the demand-responsive motor speed control results in unsurpassed lifetimes of service parts like diaphragms as well as optimal performance for backing of turbo pumps. INCLUDED: The VACUUBRAND MV 2 VARIO Select Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
