CB-B for the external gearing gear pump displacement gear pump with two kinds of spur and helical gears for liquids with a viscosity of 1 ~ 8 ° mineral oil, oil temperature at 10 ℃ ~ 60 ℃, such as hydraulic oil, mechanical oil, fuel oil. Widely used in machine tools, hydraulic machinery, engineering machinery, hydraulic systems, as the system's power source can also be used lubrication oil station, metallurgy, mining, petroleum, chemical, textile machinery and other equipment for pump, lubrication pump, fuel pump . CB-B-type gear pump is widely used in a variety of machine tools in the hydraulic system, as well as for each feed pressure oil commutation institutions, but also to the various rail surface and provide oil lubrication points, such as grinders, lathes, hydraulic machines. CB-B gear pump simple structure, low noise, oil steady, self-priming performance, reliable operation, long service life. Widely used in machine tools and large low-pressure hydraulic system mechanical equipment lubrication oil station fuel supply and cooling systems, and a variety of mechanical equipment lubrication system.
