Rotary Twin Gear Pump ( Type Dpms )

Rotary Twin Gear Pump Type DPMS General ROTOJET Rotary gear pump type DPMS is a positive displacement pump with positive pressure characteristic. Rotojet Rotary gear pump type DPMS is all SS pump, specially designed to handle thinner or thicker even corrosive liquid having lesser or no liberating value. ROTOJET rotary gear pump has a self priming capability however some net positive suction head is always required to avoid cavitations depending upon the liquid to be handled & the pump speedMOC Casing CF8Front Cover CF8Back Cover CF8Rotor Gear SS-316Stator Gear SS-316R.V.

Adjustable type Relief Valve facility offered with all model of DPMS series pumps, to rescue the pump and drive by suddenly developed back pressure & also for bypass the flow. Relief Valve is Designed to relieve 100% of capacity with in 10% to 25% of set pressure.Speed All model of DPMS series pumps are designed to run at 1440 rpm up to viscosity of 500 Cst however in higher size of above 2" pump speed is required to be reduced with increase in viscosity for consult the work. By reducing the speed the pump shaft should not be loaded with heavy gears or pulley use bearing block to take up such load.Uses Rotojet Rotary DPMS series gear pumps are ideally suited for handling thinner liquid at moderate pressuring viz. foam pressurizing application for fire fighting, medium pressure coolant transfer application, light fuel pressurizing application, heavy viscous liquid transfer application such as Molasses, Magma, Soap sock, Tar, Bitumen, Paints, Varnish, Crude, sodal etc.Future Double Helical Herringbone gear ensure no side thrust, maintains constant volumetric efficiency over longer period. Modified tooth profile enhances the tooth life, increase volumetric efficiency. Sleeve on shaft make maintenance economical & easy. Extra thick shaft gives higher bearing life, withstands bending effectively.
