At the inlet, the gears are separated from each other to form negative pressure and the liquid is sucked in. The gears are constantly embedded and engaged at the outlet and the liquid is extruded out.Because of this unique structure, it is especially suitable for conveying medium with high viscosity, viscosity range is 0.2-1000000CP;

   Internal gear pump can be reversed transmission, as long as the replacement of motor steering;
   Internal gear pump body can be turned, the import and export position at right angles, easy to choose the import and export position;
   Internal gear pump in the pump body, end cover, bearing seat are connected between convenient heat preservation or cooling medium inlet and outlet interface.
   Internal gear pump has the following advantages: trapped oil phenomenon, smooth transmission, high efficiency, low noise and long service life.
(2)  Internal gear pump is suitable for conveying petroleum, chemical, paint, dyes, food, grease, medicine and other industries in Newtonian liquid or non-Newtonian liquid, the type of conveying liquid can be from light, volatile liquid, until heavy, viscous, or even semi-solid liquid.
