Description by the supplier

VACUUBRAND MD 12 NT Diaphragm Pump



Ultimate Vacuum

2 mbar (1.5 Torr)

Maximum Pumping Speed

7.1 CFM at 60Hz

Number of Heads/Stages

8/3



Features

- Contamination-free pumping and evacuation

- High flow rate even near ultimate vacuum

- Whisper quiet

- Reduced process times

- Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs






The MD 12 NT diaphragm pump is an especially powerful pump for oil-free evacuation and pumping of non-aggressive gases. The three-stage design of this eight-cylinder pump provides the advantageous combination of very high pumping speed and excellent ultimate vacuum. The flow path consists of aluminum, stainless steel and carefully selected plastics to permit a wide range of applications. The fabric-reinforced double diaphragms are made of highly flexible FKM for extended operating life and high vacuum performance. Eight-cylinder NT pumps feature quiet operation, with smooth and easy-to-clean surfaces. Like all VACUUBRAND diaphragm pumps they operate absolutely oil-free and do not have any sliding components in the gas path. In normal operation they are completely free of abrasion. This eliminates most of the particulate impurities frequently generated inside of scroll or piston pumps.


The MD 12 NT is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases, especially for applications in physics and analytics. Due to the very good ultimate vacuum the MD 12 NT is often used as an alternative to rotary vane pumps, for example for vacuum ovens, for very quick and efficient degassing of viscous media, exhaust gas analytics and especially as backing pump for large turbomolecular drag pumps. The particularly high pumping speed enables the usage of bigger vacuum apparatus and with high gas throughput. The pump is extraordinarily silent and exhibits very low vibration making it an excellent choice for sensitive equipment such as electron microscopes. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation.

Edwards RV8 Rotary Vane Vacuum Pump

Edwards RV8 Vacuum PumpFeatures - The RV is a truly versatile pump for operation throughout for your (more) operations, perfect for wet applications, dusty applications and clean dry applications. - The RV series of pumps has the highest vapour handling capacity of any rotary vane pump. This is ideally suited for your wet pumping applications such as freeze drying, extraction, filtration and gel drying. - The best-in-class anti-suck back protection prevents dust or oil mist from entering your system. The fast-acting automatic inlet valve acts within 0.4 seconds. - The universal motor in the pump covers the widest possible voltage and frequency range from a single motor. - You can service and replace parts without dismantling the pump mechanism. All parts self-align, eliminating the need for special assembly. Pump valve has "controlled" opening on power startup so that the system vacuum will never see a pressure surge on startup The RV uses a high-quality "universal" motor to cover the widest possible voltage and frequency range. A one-size Allen key is used to dismantle all parts of the RV pump. All rotor and stator parts are completely interchangeable The RV series of small oil sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapour handling capabilities with quiet operation. With over 300,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. All RV pumps are approved to UL and CSA standards by an external test house and feature our unique mode selector switch, meaning one model is suitable for both high vacuum or high throughput applications.Click Here to View Product Video INCLUDED: The Edwards RV8 Rotary Vane Vacuum Pump includes: - Edwards Ultragrade 19 Oil - Power Cord - Manufacturer's Documentation - Operator's Manual - 1 Year Manufacturer's Warranty
