Oil Lubricated Rotary Vane Vacuum Pumps

Oil Lubricated Rotary Vane Vacuum Pumps Oil Lubricated Rotary Vane Vacuum Pumps DINESH HIGH VACUUM ENGINEERING Rotary Vane Vacuum Pumps are single stage, oil lubricated vane type with inbuilt oil-circulation and anti-suckback system. The main assembly of the pump comprises of a dynamically balanced rotor with three or four specially treated fiber vanes which is mounted in a stator. When the rotor is made to rotate with the aid of the connected electric motor, these vanes move in & out of the slots by centrifugal force & slide against the walls of the stator pushing thereby the trapped air out of the stator & prompting the atmospheric air to gush in spontaneously to fill in the empty space. This continuous process happening at a high speed, gives rise to an unbreakable stream of Vacuum and Pressure. The oil circulation system is so designed that after providing lubrication to all the vital components of the pump, oil travels ahead without contaminating the air and gets automatically collected in its original chamber for re-circulation. Advantages High Pumping Speed High Water-Vapour Tolerance Dynamically Balanced Rotor Built in Oil Circulation System Air Cooled Built-in Anti-Suckback System No Oil Mist / Fumes Low Noise Level Low Power Consumption Applications These models are quite versatile and find their applications in Pharmaceutical & Chemical Industries for Distillation, Evacuation & Filtration and is suitable for host of other general Vacuum applications like Holding, Conveying, Glass Blowing, Lamination, Labeling, Paper Feeding, Vacuum Forming, Blister Packing, Bottle Filling, Vacuum Sealing & Food Processing etc. Standard Models Model No. Air Displacement Ultimate Pressure Suction Port Inches BSP Oil Charge Ltrs.

Lyophilizer

Freeze-drying or lyophilization Freeze-drying, or lyophilization, is the process of freezing a material then sublimating any frozen liquid directly from solid to gas. The method is often used to preserve food and pharmaceuticals, as it allows products to be easily stored and transported without requiring constant refrigeration. Vacuum pumps are required for this process, and should be sized according to the freeze-dryer. If the pump’s flow rate is too high, then vapor will be pulled through the freeze-dryer’s condenser too quickly, reducing its efficiency. It is also important to clean the condenser after each run to prevent sublimation of frozen chemicals into the vacuum pump. Freeze-dryer applications require an ultimate vacuum of 10-1 to 10-3 mbar, which can be achieved with single- and two-stage rotary vane pumps or ChemStar Dry Lyophilizer

Turbomolecular pumps

Turbomolecular Vacuum Pumps For a consistent, reliable performance and zero maintenance, you can rely on Turbomolecular Pumps to deliver every time. Our first Turbomolecular Pumps were sold in 1993, we now have over 16,000 installations worldwide. 85% are operating on semiconductor process tools, where they demonstrate exceptional levels of performance and reliability. Turbomolecular Pumps are the first choice for applications demanding high up-time, hydrocarbon-free pumping, minimal maintenance and low vibration. The rotor is entirely suspended by magnetic bearings so all contact between the rotor and the remainder of the pump is eliminated. As well as giving very low vibration, the elimination of contact means no bearing contact when rotor is rotated and no requirement for consequent pump maintenance. Energy saving technologies have been incorporated into each design phase of the product development to ensure reduced power consumption and operation efficiency, with no compromise on quality or performance. Increased Productivity: Quicker Pump Down to Base Pressure Compact Size: Saves Space & Makes for Easy Installation Low Cost of Ownership: Low Power & Utilities Consumption Maintenance Free: Economic

Oil Sealed Rotary High Vacuum Pumps Oil Sealed Rotary High Vacuum Pumps These are available in single & double stage and are oil sealed, rotary vane type positive displacement pumps where, not only complete assembly is immersed in oil but shaft seal is also designed in such a way that it totally eliminates the possibility of suction of air through it. These are designed to achieve maximum vacuum in a very short time and rise in temperature of the unit also remains under check, which in turn reduces the wear and tear of its components and makes it suitable for noiseless and trouble free performance for years and thus helps in reduction of repair bills. These pumps are very compact and are so simple in design that all minor repairs, in case of need, can be carried out easily without removing the main housing from its base plate and without disturbing the alignment. In industrial models, or in vacuum pumps of higher capacities which are operated continuously for very long spells of time the oil gets heated either on account of friction or on account of heavy intake of hot mixture of gas and vapours, the performance of the pump drops. In order to keep it cool, a jacket is constructed around three sides of the pump housing, in which water is made to circulate for keeping the temperature of vacuum pump under control and retaining the performance at its best. In this model an inbuilt device, known as Gas Ballast is provided, which effectively checks to a large extent condensation of the water vapours which otherwise would not only had contaminated the oil, but had also diminished the performance of the pump. Applications Vacuum Creation, Filling, Drying, Lifting, Forming, Filtration, Distillation, Annealing, Impregnation, Dehydration, Sublimation, Film Coating & Many More.
