VACUUBRAND MZ 1C Chemistry Diaphragm Pump Ultimate Vacuum 12 mbar / 9 torr Maximum Pumping Speed 0.5 (more) cfm at 60Hz Number of Heads/Stages 2/2 Features - Outstanding chemical resistance and superior vapor tolerance. - Convenient, quick and simple to use due to the top mounted power switch. - Optimized vacuum even with gas ballast for continuous purge. - Whisper quiet and very low vibration. - Maintenance-free drive system and proven long diaphragm life. Chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The two-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE-sandwich diaphragms increase reliability and extend operating life. The MZ 1C pump is equipped with a gas ballast valve for continuous condensate purge increasing the pumping capability of condensable vapors. It features slim design for space-saving installation and good vacuum performance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory. Two-stage chemistry-design diaphragm pumps are an excellent choice for continuous, oil-free pumping of gases at medium vacuum requirements. In contrast to water jet pumps, they do not consume water and therefore do not produce any contaminated waste water. Typical applications are rotary evaporators, gel dryers, filtrations and many other lab applications. The MZ 1C is a powerful pump for smaller vacuum apparatus enabling continuous pumping of solvent vapors. It´s a compact, stand alone pump with low ultimate vacuum. If the process requires atmospheric condensation of pumped vapors or electronic vacuum control, we recommend the pump families based on the MZ 2C NT or MD 1C. INCLUDED: The VACUUBRAND MZ 1C Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND MV 10 NT Diaphragm Pump Ultimate Vacuum 0.5 mbar Max. pumping speed at 60 Hz 6.1 cfm Nu (more)mber of Heads/Stages 8/4 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Whisper quiet - Very low vibration - Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs Four-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases when the need is to reach fractional millibar ultimate vacuums. All parts in contact with pumped vapors or gases are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. These pumps provide the advantageous combination of high pumping speed with an extraordinary good ultimate vacuum down to 0.5 mbar. The highly flexible, fabric-reinforced double diaphragms made of FKM offer extended operating life. Eight-cylinder NT pumps features quiet operation, smooth and easy to clean surfaces. 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 contact seals, hence no abrasion or dust is produced that might creep back into the application. Due to the outstanding ultimate vacuum, these pumps are often used as alternative to rotary vane pumps. A typical application is the use as backing pump for turbomolecular drag pumps. Additionally, the VARIO® design 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 such as diaphragms, as well as optimal performance for backing of turbo pumps.INCLUDED: The VACUUBRAND MV 10 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Edwards Silencer for nXDS and XDS5/10 Dry Scroll PumpsFeatures - Compact design combines both filtra (more)tion efficiency and noise reduction - Integrated inlet diffuser optimizes sound attenuation - Multi-stage noise reducing features including final stage sound absorbent insert - Tubular silencing design - tube is positions to maximize attenuation and air flow while minimizing pressure drop - Patented high grade element with built-in butterfly gasket seal which creates positive seal between housing hemispheres and a new seal with each element - Seamless drawn housings - no welds to rust or vibrate apart - Durable carbon steel construction with black powder coated finish - Ability to mount vertically or horizontally The Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps has two main functions: to reduce exhaust noise during pump down and gas ballast operation as well as to collect and retain tip seal dust as the pump is operated. Exhaust gases exit the exhaust port when the pump is being used to evacuate a process chamber, or when the gas ballast control is being used, or both. The noise level when pumping down rises as the throughput increases and the silencer is used to reduce this noise level. The outer can is made of pressed steel and is split to allow access to the filter elements. The filter element housing is made from Santoprene thermoplastic elastomer. The element itself is polyester. The foam block is manufactured from filter foam. INCLUDED: The Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps includes: - NW25 Clamp - Centring Ring - Manufacturer's Documentation - 1 Year Manufacturer's Warranty
