Durga Pumps manufactures DR Series Rotary Gear Pumps for efficient transfer of oil, fuel and compatible viscous industrial liquids. Designed for dependable fluid handling, these positive displacement pumps offer consistent delivery, robust construction and convenient maintenance for a wide range of industrial applications.
Durga Pumps offers the DR Series Rotary Gear Pump for dependable transfer of oils, fuels, petroleum products and other compatible viscous liquids. Designed for steady fluid movement in industrial processes, the pump uses a positive-displacement operating principle to deliver a consistent volume with every revolution. Its robust construction, accurately manufactured gears and carefully selected components make it suitable for continuous-duty applications where reliable suction and controlled flow are important.
As a trusted Rotary Gear Pump Manufacturer in India, Durga Pumps provides multiple DR Series models for different capacity and connection requirements. The standard range extends from compact 1/4-inch models to 3-inch models, with capacities listed from 5 LPM to 500 LPM at 1440 RPM. This range allows users to select a pump according to required flow, fluid properties and operating conditions. The DR Series can be considered for transferring compatible lubricating oil, furnace oil, diesel, light fuel oil and other non-corrosive viscous fluids. Final pump selection must always be based on the liquid viscosity, operating temperature, required flow rate, discharge pressure, suction conditions and material compatibility. Share these details with Durga Pumps to receive an application-specific recommendation.
A Rotary Gear Pump is a positive displacement pump that moves liquid using two rotating gears enclosed within a close-fitting casing. As the gears rotate and separate on the suction side, they create space that draws liquid into the pump. The liquid becomes trapped between the gear teeth and the casing and is carried towards the discharge side. When the gears re-mesh, the liquid is pushed out through the delivery port. Unlike a centrifugal pump, a gear pump moves an approximately fixed volume of liquid per revolution. This makes it useful for applications that require a stable and predictable flow. Rotary gear pumps are particularly effective with clean, lubricating and viscous liquids. They are widely used in lubrication systems, oil circulation units, fuel transfer systems and general industrial fluid-handling installations.

The DR Series Industrial Rotary Gear Pump can be used in compatible fluid-transfer and circulation duties across a range of sectors, including:
Lubrication and oil-circulation systems.
Fuel and diesel transfer installations.
Handling and transfer of compatible petroleum products.
Fuel-feeding systems for boilers and burners.
Oil circulation in machine-tool lubrication units.
Fluid-transfer applications in automotive and engineering plants.
Transfer of compatible non-corrosive liquids.
Fluid circulation for textile and paper-processing equipment.
General-purpose industrial fluid-transfer systems.
Loading, unloading and tank-to-tank transfer operations.
Depending on material and seal compatibility, a Rotary Gear Pump may be considered for clean, lubricating fluids such as:
Choosing the correct pump requires more than matching the pipe connection. Provide the following information to Durga Pumps:
Confirms material and seal compatibility.
Influences pump speed, suction performance and power requirement.
Affects viscosity, clearances and sealing selection.
Helps identify the appropriate DR Series model.
Required to assess the complete duty point.
Poor suction design can cause noise, cavitation or reduced delivery.
Specify whether the application is intermittent or continuous.
Speed and power must suit the liquid and operating pressure.
Indoor, outdoor, hazardous or dusty environments may need additional provisions.
Durga Pumps focuses on practical pumping solutions for industrial liquid-transfer requirements. The DR Series offers multiple sizes and capacities, enabling users to select a model that is closer to their required duty. Clearly listed construction details and model-wise capacity data also simplify preliminary comparison.
Customers can share their liquid type, viscosity, temperature, flow, pressure and installation information to receive selection assistance. This application-based approach is important because the long-term performance of a gear pump depends on correct sizing as much as it depends on pump construction.
