Rotary Gear Pump Characteristics     Capacity:     All Positive displacement rotary gear pumps are self priming pumps in which the efficiency of transferring the liquid is deter mined by the cavity between the gear teeth.The accuracy in capacity thus depends upon the accuracy of teeth cutting and its profile. The DR series of Durga gear pumps has modified profile teeth cutting yield accurate capacity within the force range. The double helical heringesbone gear design delivers constant volume without any pulsation. It also avoids internal slipage and gives great volumetric efficiency.   Pressure:   All Durga gear pumps are self priming type pump with suction lift of 5 metres at mean viscocity and speed of 1440 RPM. The liquid flows into the pump due to a difference in pressure is called NPSH (Net Positive Suction Head), the accurate calculation of which is very much necessary for the selection of a pump. When the suction lift is more than 5 meters the pump has to be run at slow speed.The discharge pressure indicated by the pump is nothing but the over coming of pressure exerted by the resistance of the pipeline and the shearing force of the Liquid.Thus a gear pump does not develope pressure by its own but work against the system pressure exerted on it.  

Special application pump designed to be used with a wide variety of media that cannot be pumped using a regular cast iron or steel pumpBody made from glass filled polypropylene with ryton vanesViton rubber seal & stainless steel hardwareComplete with 3 pc threaded suction tube suitable for use on 50-210 litre drumsWETTED COMPONENTSPolypropylene, Ryton, Viton & Stainless SteelRECOMMENDED USEWater based media, acids, chemicals, detergents, benzene, glycerine etc. DO NOT USE WITHAcetone, Lacquer, Mineral Oils, Solvents, Turpentine etc.

rotary gear pumps are useful for handling viscous liquids i.e. All kinds of oils, viscous chemicals, and food application. Following liquid can be handle with them. Rotary gear pumps finds wide application in power plant, steel mills, refineries, oil storage instolations etc. compact in size low noise high efficiency easy to maintain low cost

Oil Sealed Rotary High Vacuum Pumps are of oil-immersed, rotary vane type pumps from 0.25 HP to 20 HP in One/Two Stages.   These are of oil-immersed, rotary vane type pumps. The rotor, with two spring loaded vanes, is mounted eccentric in the stator body. As the rotor, rotates the vanes sweep the crescent shape air space twice in each revolution. There is in-built non-return valve which prevents back flow of air.   Manufactured from graded material, all moving parts are precisely machined, ground and assembled with close tolerances. This results in increased efficiency and long trouble free operating life.   APPLICATIONS   ·        Distillation ·        Dehydration and filtration processes. ·        Exhausting Electric Tubes -        GLS Lamps,  Mercury Vapor Lamps and Tubes. ·        Vacuum Metaiiurgy -        Vacuum Sublimation, Vacuum impregnation, Thin film Coating ·        Refrigerator and Air-conditioner servicing. ·        Freeze drying of Foods.
