External Gear Pumps
Foot / Flange Mounted Rotary Gear Pumps :Type RGP / HGP / CGX
RGP / HGP Foot Mounted CGX-Flange Mounted CGXM-Close Coupled Monoblock Type Mini Monoblock Gear Pumps

The “ DEVPUMPS ” / “ DEV ” ‘s RGP / HGP Series Positive Displacement Rotary External Gear Pumps are most efficient and economic range with variety of materials for transferring of oils & viscous liquid, which has special features like Simple & compact in design, Low Noise Level, High in Efficiency and Easy to maintain. It has two piece construction with pump body and cover. The Pump’s element is a pair of single helical modified profile alloy steel gears , which is shrink fitted on carbon steel harden and ground shaft.  And it is supported on either side by self lubricated, oil impregnate, sintered bronze bush bearing , which ensures longer life and smooth performance of pumps. The shaft sealing is by Neoprene Rubber oil seal , which  ensures leak proof working than gland packing design.  The in – built pressure relief vale design gives safety against overloading of electric motor and release excess pressure . This pumps are available in different sizes and capacity with maximum working pressure 10 Kg/cm2 from 2.5 LPM to 500 LPM with ¼” to 3” sizes. 

The flange mounting type pump is suitable for mounting on any equipment or machine. The company is also provide right angle L-type mounting bracket in different frame size to make it foot type pump. By this during the maintenance period you can easily dismantle the pump without disturbing the alignment with motor , which is the main advantage of flange type gear pump .

Design features : Go to Top
The “ DEVPUMPS “ / “ DEV “ ‘s GP / DIRN / DIRB / DIMS -series Positive Displacement Double Helical ( Herringbone ) External Gear Pumps are design in three piece construction with pump body, front cover and back cover with in-built pressure relief valve. The front cover ( stuffing box ) has extra deep to minimize the leakage. These pumps can supply with mechanical seal type arrangement for leak proof application on special request .The special double helical gears eliminates the axial thrust & prevents trapping of the liquid between the teeth, resulting in maximum pumping efficiency , smooth flow and quite operation. The pump has large diameter shaft , which eliminate shaft deflection problems and gives maximum bearing life. A special type of bush bearing arrangement is provided in these pumps. By this the replacement of the bushes is done very easily and quickly by the removing the end covers. So the wear and tear of the pump body and gears due to play in the bushes can be easily avoided by constant checking of the bushes and easy replacement. The pumps are also supplied with ball or needle roller bearings, if pumping liquid has lubricating property. In built pressure relief valve design does not allow to develop excessive pressure by the pump, if the discharge line is closed. The jacketed features are also available on special request.
