FEATURES
- SIG Series positive displacement gear pumps are self priming pumps which has totally new pumping concept resulting reliable and simple design.
- Manufacturing techniques ensure more accuracy in dimensions, interchangeability and pump characteristics.
- There are only two pumping elements in internal gearing principle, this result in unmatched suction characteristics that is impossible in double helical gear pumps.
- There is only one shaft well supported at both ends of rotor for smooth, vibration free running and eliminating bearing problems normally found in the conventional gear pump.
- The noise level is very low and this series needs practically no maintenance and much longer service life then other gear pump.
- Precision machined components guarantee high volumetric efficiency and overall efficiency.
- Internal gearing principle with axial flow ensures pulsation free continuous flow.
- Compact and light weight design eliminates elaborate foundations.
- Single shaft design permits pump dismantling without removing pump from base or disconnecting pipes. Pump can be serviced in place.
- Available in bare shaft pump, mono block pump and motor coupled pump design.
APPLICATIONS
“SIG” Series rotary gear pumps are used to handle lubricating oils, fuel and other fluids which have lubrication properties. These pumps are ideally suited for following typical applications.
- To transfer or circulate the fuel oils, lube oils and neutral liquids with lubricating properties.
- Gear lubrication, oil circulation, through cooler, cooling of bearings and in pressure lubrication.
- To transfer all kind of oils without solid particles.
- Boosting of fuel oil pressure for oil burner service and fuel injection pumps.
- Unidirectional flow designs for reversing shaft duties as in machine tools, gear boxes and crane duties.
- Transfer of fuel oils to daily service tanks, preheating circulating etc.
- Transfer of lubricating oils when emptying barrels and tanks.
