Contact SupplierProven Principle of Internal Gear is used in pumping. Rotor (Outer Gear) is keyed to drive shaft whereas idler (Inner Gear) is located eccentrically on a pin on the front cover. Both the gears are in mesh and the ports are sealed by a crescent located at the front cover. As the rotor and idler gear un-mesh, an under pressure is created and the liquid enters the new created cavities. Liquid is transported in sealed pockets to the discharge side. The walls of the pump casing and the crescent are creating a seal and separate suction from discharge side. The rotor and idler gear mesh pushing the liquid into the discharge line. Reversing the shaft rotation will reverse the flow through the pump as well.
