Apollo mechanical industries designs and supplies the most efficient and economic range of positive attitude rotary gear pumps. These rotary gear pumps have extraordinary features, like simple and compact design, low noise, high spirit, easy-to-maintain, reliable and lower price. These rotary gear pumps find their applications in: chemical, petrochemical, food, oil, steel, refining, paints, dairy, sugar and pharmaceutical industries. These rotary gear pumps are best suited for handling viscous liquids, like all kinds of oils, viscous chemicals and food application. All positive displacement rotary gear pumps are selfpriming pumps in which the efficiency of transferring the liquid is deter mined by the cavity between the gear teeth. Following are some of the technical features of these gear pumps: the accuracy in capacity thus depends upon the accuracy of teeth cutting and its profile. The dr series of gear pumps has modified profile teeth cutting yield accurate capacity within the force range. Constant volume without any pulsation is delivered by the double helical heringsbone gear design. All gear pumps are self-priming type pump with suction lift of 5 metres at mean viscosity and speed of 1440 rpm. The discharge pressure indicated by the pumps is nothing but the over coming of pressure exerted by the resistance of the pipeline and the shearing force of the liquid.
