We manufacture high performance gear pumps that are positive displacement type having spur, helical or herring bone pair of gears. Gears are precision hobbed and press fitted and keyed to a drive shaft. The basic types of gears are:
Gear Types Available
- Internal gear pumps
- External gear pumps
- Foot-mounted internal gear
- Herringbone gear
More Application Examples
- Pressurizing fuel oil
- Machine tool lubrication
- Oil transfer & circulation
- Hydraulic power packs
Typical capacity up to 2000 LPM and withstands pressures of about 30 kg/cm² (application-dependent).
Design Features
- Back pullout-flanged design which facilitates easy maintenance without disturbing installed pipelines. Flanged end connections dismantling andinstallation is very convenient.
- Double helical herringbone gear design ensures'no' side thrust, maintains constant volumetric efficiency over longer period, for higher models only.
- Lesser number of modified profile teeth on rotors gives low moment of inertia, low frictional losses and high tooth life.
- Extra heavy shaft gives higher bearing life. Withstands bending load effectively.
- Low leakage path by design gives high volumetric efficiency.
- Equal-rating flanges on suction and delivery allows running of the pump in either direction.
- Pressure relief valve facilitate easy changeover of the direction.
