The internal gear pump was invented more than 100 years ago, but at that time the invention has significant drawbacks: lower efficiency due to low gear engagement ration, larger noise and vibration, non-conformance with API standards. Currently this traditional gear pump technology is still widely used by many pump manufacturers.

After technical innovation, our SMC internal gear pumps features:

1.efficiency increased 10%

2.noise reduced 10%

3.vibration reduced 0.8 mm/s

4.pressure balance design

5.drain port design at pump bottom

6.gear engagement ratio up to 1.3

7.high-speed design

Gear pump wide application:

1.chemicals: plastics, resin, paint, printing inks, soap, rubber, pigment, drug

2.refined oil: fuel oil, asphalt, lubricating oil, tar, marine fuel oil

3.food: chocolate, dairy, beverage, edible oil, molasses, animal food

4.machinery:engine&turbine, pump&compressor, farm machinery, packing machinery, printing machinery, construction machinery, machine tools

5.other:refrigeration, metal, pulp&paper, heating equipment, utilities
