Durga Pumps’ DRX Series is a self-priming, bi-directional rotary gear pump designed for industrial liquid transfer. It features a two-piece cast iron body, carbon steel helical gears, hardened alloy steel shafts, and self-lubricating bronze bushes for dependable operation. Suitable applications include oil filtration, heating, cooling, centralized lubrication, petroleum processing, and machine tools. Available capacities range from 10 to 225 LPM at 1440 RPM.
Apollo Road Equipments manufactures, supplies, and exports Flange Mounting Rotary Gear Pumps under the brand name Durga Pumps. The DRX Series is a self-priming, bi-directional positive displacement pump featuring a two-piece cast iron body and modified-profile, single-helical carbon steel gears.
The gears are shrink-fitted onto hardened and ground alloy steel shafts, supported by four self-lubricating sintered bronze bushes. The pump can operate in either direction, with the inlet and outlet ports exchanging roles when rotation is reversed. Relief valve operation can be adapted by repositioning the valve components to the opposite side.
The DRX Series uses a self-priming, positive displacement gear mechanism for liquid transfer in industrial pumping and lubrication systems.
A two-piece cast iron body houses modified-profile carbon steel helical gears mounted on hardened and ground alloy steel shafts.
The pump supports rotation in either direction. The inlet and outlet ports exchange roles when the direction of rotation changes.
Four self-lubricating sintered bronze bushes support the shafts, providing bearing support for the rotating components.
Relief valve operation can be adapted to the rotation direction by repositioning the valve components to the opposite side.
Suitable for oil filtration, heating, cleaning, cooling, centralized lubrication, petroleum processing, and machine tool systems.
Capacities at 1440 RPM. Select a model to request its price and delivery time.

Suitable for liquids that demand hygiene, corrosion resistance or accurate, steady flow.
Transfer and circulation of compatible oils during filtration.
Liquid transfer and circulation in industrial heating processes.
Circulation of compatible cleaning and cooling fluids.
Oil supply to multiple machinery lubrication points.
Transfer of compatible petroleum-based oils.
Lubricating oil circulation for machine tools and associated equipment.
It is a self-priming, positive displacement pump that uses rotating gears to transfer compatible liquids in industrial systems.
Yes. Reversing rotation exchanges the inlet and outlet ports. The relief valve components must also be repositioned for the required direction.
The pump features a cast iron body, carbon steel helical gears, hardened alloy steel shafts, and self-lubricating sintered bronze bushes.
Available models offer capacities from 10 to 225 LPM at 1440 RPM. Actual flow depends on the liquid and operating conditions.
Applications include oil filtration, heating, cleaning, cooling, centralized lubrication, petroleum processing, and machine tool systems.
Selection depends on liquid compatibility, viscosity, temperature, required flow rate, operating pressure, and installation requirements.
