FXB Outer Lubrication Stainless Steel Gear Pumps Power transmission gears and fluid delivery gears are located in separate pump chambers and are designed and manufactured to their own unique function for superior pump reliability. FXB in FXA pump type, based on the increase of a support, improve the working pressure, and designed to flange connection. The pump has a mechanical seal and packing seal in two forms. Scope of application: Suitable for transporting non-lubricity, corrosive, high hygienic conditions do not contain solid particles, fibers and other substances of general viscosity and high viscosity fluid. Medium temperature -20-80 ℃, viscosity 5-5000cst. Uses: used in machinery, petroleum, chemicals, food, medicine, metallurgy, printing and dyeing, brewing, cosmetics, beverages and other industries. Structural features: The power transmission gear and the fluid delivery gear are in different pump chambers, which are designed and manufactured according to their different functions, therefore, the pump has higher reliability. FXB in FXA pump type, based on the increase of a support, improve the working pressure, and designed to flange connection. The pump has a mechanical seal and packing seal in two forms.
