Long diaphragm life, maintenance-free drive systemĦ.1 VACUUBRAND warrants that its delivered goods (including any agreed installation) are free of defects at time of risk transfer.Excellent ultimate vacuum even with gas ballast.Exceptionally high performance even at low vacuum.Outstanding chemical resistance and superior vapor tolerance.This powerful 110v pump is at the heart of a complete family of well-proven and reliable vacuum systems and pumping units for larger lab applications. The MD 4C NT has an outstanding performance for pumping large amounts of vapor, e.g., out of drying ovens and gel dryers. Typical applications are parallel and rotary evaporators, concentrators, drying ovens and many other laboratory applications. Three-stage chemistry diaphragm pumps are an excellent choice for applications with corrosive gases and vapors with high vacuum requirements. The NT-series features further improved performance data, easy service and superior vapor tolerance. Due to the gas ballast valve and its very good ultimate vacuum (even with gas ballast) the MD 4C NT is also suitable for pumping condensable vapors of high-boiling solvents. Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. All parts of the MD 4C NT in contact with pumped media are made of chemically resistant fluoroplastics. The three-stage design provides the advantageous combination of high pumping speed and very low ultimate vacuum. ![]() It has been widely used in metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum and medicine production and scientific research departments.Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet even challenging requirements. The pump can be used alone, and it can also be used as a foreline pump for other high vacuum pumps or ultra-high vacuum pumps. But it is not suitable for pumping gases that contain excessively high oxygen, corrosive to metals, chemically reactive to pump oil, and particulate dust. Rotary vane vacuum pump can remove the dry gas in the sealed container, and if there is an air ballast device, it can also remove a certain amount of condensable gas. Therefore, the rotary vane vacuum pump is generally oil-sealed mechanical vacuum pump. Usually, the gap between the rotary vane and the pump cavity is sealed by oil. Rotary vane vacuum pump is a kind of rotary variable volume vacuum pump and its structure is that the rotor eccentrically installed in the pump is tangent to the stator on fixed surface and two (or more) rotary vanes slide in the rotor slot (usually radial) and contact with the inner wall of the stator to divide the pump cavity into several variable volume. Large torque design makes the vacuum pump easy to startup, even under low temperature environment (5℃) or low voltage.Īpplications: The 1-stage oil-sealed rotary vane vacuum pump is widely used for vacuum packaging, vacuum freezing, automobile maintenance, HVAC work, air conditioning, refrigeration and other vacuum evacuation.Oil anti-back valve designto prevent oil from flowing back to pollute the pump system when the pump stops.Oil drain plug at the bottom of oil reservior for fast draining.Big oil sight glass for viewing oil level.Built-in high-volume cooling fan to provide thermal protection and extend service life.Direct dirve motor with full copper wire structure, easy starting and strong construction.Lightweight and durable aluminum alloy casing.1/3 HP 4.5 CFM/5 CFM rotary vane vacuum pump features high efficiency and low noise, easy to operate with ON/OFF switch, affordable price and high performance.
