Advantages of stainless steel gear pump castings

The main products include stainless steel gear pump forging products , ordinary sand casting products, casting products and silica sol casting products. Exquisite appearance , beautiful, low noise, long service life . Equipment for the chemical and corrosive product of choice . ZB-B series stainless steel gear pump gear involute helical gear structure , the use of corrosion-resistant fluorine rubber oil seal and PTFE packing and assembled a high temperature , good sealing effect , high temperature . Special working conditions can be made ??of stainless steel corrosion-resistant mechanical seal. Stainless steel gear pump gear common to have straight teeth , helical , herringbone gear , helical gear , involute tooth profile of the main types of lines and arcs . Gear pumps are usually small and more involute spur gears , gear pumps often used high-temperature shifted gears , transmission of high viscosity, high-pressure melt the polymer melt pump to use more involute helical gears. Gear formed integrally with the shaft , its rigidity and reliability of the shaft above the gear pump gears made separately . Foreign pressure gear pump gear often used a square structure, namely the gear tooth width equal to the tip diameter . High viscosity and high pressures using a pump gear teeth of a width less than the diameter of the addendum circle , which is to reduce the radial pressure receiving area of ??the gear, the gear to reduce the bearing load. Stainless steel gear pump is a new type of transmission fluid machinery, has a simple structure , safe and reliable , easy maintenance , the liquid continuous uniform, stable pressure ....
