Product Description

External Gear pump

Product Features

External gear pump uses two external helical gears. In this, one gear is driven by the prime mover and drives another gear. The gears are supported by bearings in both side of the gear shaft. As the gears rotate they separate on the intake side of the pump, creating a void and suction which is filled by fluid. The fluid is carried in the teeth cavity to the discharge side of the pump, where the meshing of the gears displaces the fluid. The mechanical clearances are fixed to suit the liquid viscosity, to keep the slip minimum. As the shafts are supported at both the sides, these pumps are highly suitable for highly viscous fluids like resins, soap stocks etc. besides for normal fuel/lube oil applications. Because of the precise clearances between the gears to suit the application and fluid properties, these pumps are well suited for precise applications.
