20L/min (1.2 m3/h)

Protection Class

IP44



Features

- Clean, 100% oil-free operation

- Corrosion-resistant PTFE/FFPM flowpath

- Ideal for extremely aggressive/corrosive gases and vapors

- Compact, quiet and reliable

- Self-drying system removes condensate without affecting the vacuum level

- Maintenance-free





The chemically-resistant series N820.3FT.40P diaphragm pump is a two-stge unit with an integrated PowerDry self-drying system. There is a wide range of applications for this pump in laboratories, especially whenever clean vacuum is required and moist gases must be pumped down. Examples include vacuum-drying of vacuum oven chambers (for drying or heat-treating substances and components) or steam sterilizers for sterilizing instruments, vessels, filters and textiles. Due to its high resistance to aggressive media, this pump can be used universally.


The heart of these very compact pumps are KNF structured diaphragms (PTFE-coated). These patented diaphragms were stress-optimized using the Finite Elements method. As a result, we were able to make the pumps smaller while increasing the service life of the diaphragm. This pump is 115V.

VACUUBRAND MZ 2C VARIO Select Chemistry Diaphragm Pump

VACUUBRAND MZ 2C VARIO Select Chemistry Diaphragm Pump Ultimate Vacuum 7 mbar (5 Torr) Maximum Pump (more)ing Speed 1.65 CFM at 60Hz Number of Heads/Stages 2/2 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 - Excellent chemical resistance The MZ 2C VARIO select pump is an excellent solution for labs working with most common solvents. The integrated VACUU-SELECT controller provides an easy-to-use, application-based interface that covers all common lab applications. The VACUU-SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU-SELECT controller detects the boiling pressure and automatically adjusts the pump to maintain process control. On-demand motor speed control yields not only improved vacuum control, but it also results in unparalleled service intervals for wear parts like diaphragms and valves. Typical applications are all evaporation processes. Evaporation processes can be run fully automatically and with short process times and high sensitivity at the same time. The VARIO control ensures high process reliability through prevention of superheating or foaming. The control allows for automatic vacuum level adaptation and is self-adapting to changing process parameters at any time. The VACUU-BUS interface facilitates a user-friendly configuration of even complex vacuum installations. INCLUDED: The VACUUBRAND MZ 2C VARIO Select Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND MD 12 NT Diaphragm Pump-cover
VACUUBRAND MD 12 NT Diaphragm Pump

VACUUBRAND MD 12 NT Diaphragm Pump Ultimate Vacuum 2 mbar (1.5 Torr) Maximum Pumping Speed 7.1 CFM  (more)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. INCLUDED: The VACUUBRAND MD 12 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
