Rotary Internal Gear / Lobe Tracoidial Pump by Dev Engineers

The “ DEVPUMPS ” / “ ROTOWELL ” ‘s DSIG series are totally new pumping concept resulting in exceptionally reliable, economy & simple design. Advanced technology ensures accuracies in dimensions, interchangeability, pump characteristics and at the same time the cost of end product is considerably reduced than conventional pumps.
Design Features :In DSIG series, there are only two pumping elements in latest internal gearing cum lobe principle. The flow of liquid is axial through the elements. This results in unmatched suction characteristics that are impossible in double helical external gear pumps. Also there is only one shaft well supported at both ends of rotor for smooth, Silent, vibration-free running and eliminating bearing problems normally found in conventional gear pumps. Consequently, series DSIG series pump has a very low noise level. This series needs practically no maintenance and has much longer service life than other types.
Application

This DSIG series of Internal Gear pumps has been designed to handle fuel and lubricating oils as well as other fluids with similar properties. These pumps are therefore ideally suited for following typical applications:

• Transfer of lubricating oils when emptying barrels and tanks.
• Pressure lubrication and cooling of bearings, oil circulation through cooler, gear lubrications etc.
• Transfer of fuel oils to daily service tanks, preheating, circulation etc.r lubrications etc.
• Transfer of fuel oils to daily service tanks, preheating, circulation etc.
• Boosting of fuel oil pressure for oil burner service and fuel injection pumps.
• Unidirectional flow design for reversing shaft duties as in machine tools, gear boxes and crane duties
