Double Helical Rotary Gear Pump (Series - DRRN/DRRX)

Double Helical Rotary Gear Pump

Double Helical Rotary Gear Pump (Series - DRRN/DRRX)

Apollo Road Equipments is the leading crude oil pump manufacturer, we design and manufacture extremely reliable and long lasting double helical rotary gear pump using high quality components and high end technology. We have a cutting edge production unit which manufactures heavy duty foot mounting type positive displacement rotary twin gear pump which are widely used in chemical plants to pump high viscosity fluids. This makes us the most trusted crude oil pump manufacturer in India. Our highly advanced bitumen pump have double helical gear to prevent axial load & side thrust which helps increase the longevity and performance. These pumps are widely used for transferring those viscous liquids which because of their offending nature could not be handled by pumps of PSG Series. Recommended for liquids like crude oil cottonseed oil, dirty lube oil, High Speed Diesel, our rotary gear pump are suitable for liquid up to viscosity of 1,00,000 SSU. Being the best bitumen pump manufacturers in India, we offer the most efficient and economic range of Positive Displacement Double Helical Gear Pump. We are prominent suppliers and exporters of highly reliable, easily portable, compact size double helical pumps. All our Molasses pump have special features, simple & compact design. They are also appreciated by our clients for low noise, easy maintenance and high efficiency.

Apollo Road Equipments is Manufacturers of Molasses Pump and it can be operated up to pressure of 10 kg/cm� with 8.30 LPM to 2000 LPM flow capacity and are suitable for liquid up to viscosity of 1,00,000 SSU and maximum temperature up to 200�c.

Selection Of Double helical Gear pump.

DRRN/ DRRB

The self lubricated needle roller bearing type Model DRRN used for clean viscous liquid having sufficient lubricating property such as clean lube oil, Gear oil, Animal oil, Fish oil, Hydraulic oil, Honey, Vegetable oil, SAE lubricating oil for continues duty, However for Intermittent duty Bush Bearing type pump Model DRRB used.

Model DRRX

This Model independent lubricated needle roller bearing type pump is suitable for handling of Crude oil, Dirty lube oil, HSD, Kerosene, LDO, Paints, Varnish, Wood Pulp, Liquid which have poor lubricant value.

Model DRRBJ

This Model should be selected for liquid which tends to solidify at room temperature such as Bitumen, Furnace oil, Asphalt, Tar, Starch, Molasses, Naphtha, RFO, Silicate, Wax, Soap solution. Because This model have jacketing construction facilitate the heating the pump by steam or thermic fluid.
