Vacuubrand MD 4C NT 2.2 CFM Chemistry Diaphragm Pump 110V   MD 4C NT Technical Data Sheet.pdf  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.   Performance 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 very low vibration Long diaphragm life, maintenance-free drive system     Technical Data Max. pumping speed 50 Hz 3.8 m3/h Max. pumping speed 60 Hz 2.5 cfm Ultimate vacuum 1 mbar / 0.75 torr Number of heads 4 Number of stages 3 Lower ambient temperature (operation) 10 °C Upper ambient temperature (operation) 40 °C Lower ambient temperature (storage) -10 °C Upper ambient temperature (storage) 60 °C Max. back pressure (abs.) 1.1 bar Anschluss saugseitig small flange KF DN 16 Outlet connection Silencer / G1/4" Rated motor power 0.25 kW Rated motor speed at 50/60 Hz 1500/1800 min-1 Protection class IP 40 Dimension L in mm 328 mm Dimension W in mm 239 mm Dimension H in mm 198 mm Weight 16.4 kg Noise level at 50 Hz, typ. 45 dBA Rated mains voltage range 1 230 V Mains frequency 1 50-60 Hz   NRTL certification

Vacuubrand MD 1C Chemistry Diaphragm Pump   Chemistry diaphragm pump in action 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.  Performance 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     Technical Data Max. pumping speed 50 Hz 1.3 m3/h Max. pumping speed 60 Hz 0.88 cfm Ultimate vacuum 2 mbar / 1.5 torr Ultimate vacuum with gas ballast 4 mbar / 3 torr Number of heads 4 Number of stages 3 Lower ambient temperature (operation) 10 °C Upper ambient temperature (operation) 40 °C Lower ambient temperature (storage) -10 °C Upper ambient temperature (storage) 60 °C Max. back pressure (abs.) 1.1 bar Anschluss saugseitig Hose nozzle DN 8-10 mm Outlet connection Hose nozzle DN 8 mm Rated motor power 0.08 kW Rated motor speed at 50/60 Hz 1500/1800 min-1 Protection class IP 40 Dimension L in mm 316 mm Dimension W in mm 143 mm Dimension H in mm 175 mm Weight 6.9 kg Noise level at 50 Hz, typ. 45 dBA Rated mains voltage range 1 200-230 V Mains frequency 1 50-60 Hz     Brochure
