Description by the supplier

VACUUBRAND MD 1 Diaphragm Pump



Ultimate Vacuum

1.5 mbar (1.1 Torr)

Maximum Pumping Speed

0.82 CFM at 60Hz

Number of Heads/Stages

4/3



Features

- Contamination-free pumping and evacuation

- High flow rate even near ultimate vacuum

- Excellent ultimate vacuum

- Whisper quiet and ultra-low vibration

- Proven long diaphragm life, maintenance-free drive system






The MD 1 diaphragm pump is an excellent choice for oil-free evacuation and pumping of non-corrosive gases down to 1.5 mbar ultimate vacuum. The three-stage design with precisely guided flat diaphragms provides outstanding pumping speed even close to the ultimate vacuum, especially when compared with similarly rated two-stage diaphragm pumps. The MD 1 is an ultra-low vibration pump with very long diaphragm lilfetime and stable ultimate vacuum documented with years of testing. With a flow path consisting of aluminum and selected plastics (diaphragms and valves made of PTFE/FKM and FKM, respectively) the pumps are suitable for a wide range of applications with non-corrosive gases. The MD 1 is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases. It is suitable for high vacuum requirements at modest gas flow as often needed in physics and analytics. The pump is exceptionally quiet and reliable with long diaphragm and valve lifetimes. With its low ultimate vacuum and compact dimensions the MD 1 is widely used as replacement of rotary vane pumps. Typical applications are exhaust gas analysis, for degassing of small amounts of viscous media and in particular as backing pump for compact turbomolecular drag pumps. 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.INCLUDED:

The VACUUBRAND MD 1 Diaphragm Pump includes:

- Power Cord

- Operator's Manual

- Manufacturer's Documentation

- 2 Year Manufacturer's Warranty

VACUUBRAND Chemistry Diaphragm Pump MD 1C Ultimate Vacuum 2 mbar Max. pumping speed at 60 Hz 0.88  (more) cfm Number of Heads/Stages 4/3 Features - Outstanding chemical resistance and superior vapor tolerance - Exceptionally high performance even at low vacuum - Excellent ultimate vacuum even with gas ballast - Whisper quiet and ultra low vibration - Proven long diaphragm life, maintenance-free drive system Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet high requirements regarding ultimate vacuum. The three-stage construction provides the advantageous combination of high pumping speed and deep ultimate vacuum in a pump with a very small footprint. All parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms increase reliability and extend operating life. The MD 1C with gas ballast valve is optimally prepared for pumping easily condensable vapors (high boiling solvents). Three-stage chemistry diaphragm pumps are an excellent solution for applications involving corrosive gases and vapors at high vacuum requirements. Typical applications are vacuum generation at rotary evaporators, vacuum concentrators and many other laboratory applications. Due to their excellent ultimate vacuum they are the ideal solution for evaporation of high boiling solvents even with gas ballast. The MD 1C pump is the heart of a whole line of reliable chemistry pumping units.INCLUDED: The VACUUBRAND Chemistry Diaphragm Pump MD 1C includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
