VACUUBRAND MD 4 NT Diaphragm Pump



Ultimate Vacuum

1 mbar

Max. pumping speed at 60 Hz

2.5 cfm

Number of Heads/Stages

4/3



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






These three-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of non-corrosive gases. They reach an excellent ultimate vacuum of 1 mbar. All parts in contact with pumped gases and vapors are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of applications with non-corrosive gases. The new NT-series provides whisper quiet and ultra-low vibration operation, high leak tightness and improved performance. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. 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 in physics and analytics. The low ultimate vacuum makes these an attractive alternative to rotary vane pumps in many applications. Typical uses are as backing pump for turbomolecular drag pumps, and for degassing of viscous media.INCLUDED:

The VACUUBRAND MD 4 NT Diaphragm Pump includes:

- Power Cord

- Operator's Manual

- Manufacturer's Documentation

- 2 Year Manufacturer's Warranty

VACUUBRAND MD 4 VARIO Select Diaphragm Pump-cover
VACUUBRAND MD 4 VARIO Select Diaphragm Pump

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
