Product overview
Details that help confirm the fit.
The Durga DFIG 600 is a self-priming, positive-displacement internal gear pump designed for fuel injection, pressure boosting and liquid-fuel transfer applications. It has a nominal capacity of 600 litres per hour at 1440 RPM and is suitable for operation at pressures up to 30 kg/cm².
The pump is designed to handle LDO, furnace oil, diesel, HSD, LSHS and other compatible non-corrosive and non-abrasive liquids. It can handle liquids with viscosity up to 500 cSt and temperatures up to 200°C, subject to correct pump selection, sealing arrangement and operating conditions.
The DFIG 600 features flange mounting, precision-cut gear profiles and close manufacturing tolerances to provide consistent capacity across the specified pressure range. Its self-priming design assists fuel withdrawal and transfer from storage or service tanks.
A built-in pressure-relief valve and bypass help protect the pump and fuel circuit from excessive pressure. The mechanical shaft seal is designed to minimize leakage during operation.
The pump body and eccentric are manufactured from FG 220 grade cast iron. The idler gear and rotor shaft are manufactured from SAE 8620 material, while the piston and pressure-adjusting screw use EN 8 material.
Typical applications include oil burners, industrial boilers, furnaces, ovens, thermic-fluid heating systems, fuel-injection installations, diesel and LDO transfer systems, hydraulic systems and diesel-locomotive booster applications.
Pump rotation, coupling alignment, motor selection, filtration, pipe sizing, relief-pressure adjustment and commissioning must be verified by qualified personnel. The pump should not be operated dry or used with corrosive, abrasive or otherwise incompatible liquids. ``
Model, voltage, rotation, pressure range and mounting can vary. Final compatibility is confirmed against the nameplate or existing component.
